Facebook ad sizes and specs cheat sheet for 2026

Key takeaways

1. The most versatile Facebook ad size is 1080 x 1080 pixels (1:1), which works across Feed, Marketplace, carousel, and search results placements.
2. For Stories and Reels, use 1080 x 1920 pixels (9:16) to fill the full screen on mobile.
3. When running Feed ads on mobile, 4:5 aspect ratio (1080 x 1350) gives you more screen real estate than 1:1.
4. All specs below are current as of 2026 and sourced from Meta’s official Ads Guide.

Facebook advertising guidelines

Before you dive into placement-specific sizes, it helps to know the rules that apply to almost every Facebook ad you’ll run. A few quick notes first: “facebook ad sizes” and “meta ad sizes” refer to the exact same specs, since Facebook is one product inside Meta’s family of apps. For a detailed overview of the different formats, check out this guide on Facebook ad tools.

Here are the universal guidelines to keep in mind:

• Default to 1080 x 1080 pixels. If you can only make one asset, the 1:1 square is the safest choice because it displays cleanly across the most placements.
• Use 4:5 for mobile Feed. A 4:5 aspect ratio (1080 x 1350) takes up more vertical space in the mobile feed, so your ad occupies more of the screen as people scroll.
• Go 9:16 for full-screen placements. Stories and Reels are vertical, so use 1080 x 1920 pixels to fill the whole screen.
• Keep text on images light. Meta no longer enforces the old 20% text rule, but ads with less text on the image still tend to get broader delivery and better results, so put your key message in the ad caption instead.
• Respect safe zones. On vertical formats, UI elements and CTA buttons cover the top and bottom of the frame. Keep your key visuals and copy in the center of the canvas.
• Give Advantage+ room to work. When you use Advantage+ placements through your ads manager, Meta automatically adjusts and crops your creative to fit each placement, so upload the highest-resolution assets you can.

Facebook feed ad sizes

The Facebook news feed is probably what you think of most when it comes to Facebook ad sizes. It’s the endlessly scrollable place to find all your friends’ status updates, photo posts, videos, and more, plus content from brands and Facebook Pages you follow.

Facebook feed ads come in many styles, from carousel ads to single image or video ads, and choosing the right format is a key part of your ad campaign strategy. The second item in a user’s feed is an ad, with more mixed between organic content as a user continues scrolling.

For the mobile feed, 4:5 aspect ratio is usually the better choice because it takes up more screen space and pushes competing content out of view, a difference you can confirm in your paid ad analytics, especially since 81.8% of Facebook users access it only via mobile.

If your ad will run across multiple placements, 1:1 is the safer default since it crops predictably everywhere. The same feed specs apply if you’re advertising in the dedicated video feed (the video tab you reach from the desktop app or the mobile menu), where video ads appear with a “sponsored” label alongside organic clips.

Facebook feed image ad sizes

• Display size: 1440 x 1440 pixels (1:1 ratio) or 1440 x 1800 pixels (4:5 ratio)
• Minimum image ad width: 600 pixels
• Minimum image ad height: 600 pixels (1:1 ratio) or 750 pixels (4:5 ratio)
• Aspect ratio: 1:1 or 4:5
• File type: PNG or JPG
• Maximum file size: 30MB

Facebook feed video ad sizes

• Display size: 1440 x 1440 pixels (1:1 ratio) or 1440 x 1800 pixels (4:5 ratio)
• Minimum video ad width: 120 pixels
• Minimum video ad height: 120 pixels
• Aspect ratio: 1:1 for desktop or mobile, or 4:5 for mobile only
• File type: MP4, MOV, GIF
• Recommended video settings: H.264 compression, square pixels, fixed frame rate, progressive scan and stereo AAC audio compression at 128kbps+
• Maximum file size: 4GB
• Maximum video length: 241 minutes

Facebook carousel ad sizes

Facebook carousel ad types allow you to showcase between two and 10 images, videos, or a mix of both and link each one to a separate URL or landing page. These are one of the most popular Facebook ad formats thanks to their versatility and having so many placement options across Facebook on desktop and mobile.

Carousel isn’t limited to the feed either. You can run carousel ads in Stories, Reels, and in-stream placements too, and the specs stay the same at 1:1. One of the most effective carousel formats is collection carousel ads, which pull images and links from your connected product catalog to automatically generate relevant, conversion-focused ads for e-commerce retailers.

Facebook carousel image ad sizes

• Display size: 1080 x 1080 pixels or larger
• Aspect ratio: 1:1 (4:5 is supported only for Advantage+ catalog carousel ads)
• File type: PNG or JPG
• Maximum file size: 30MB

Facebook carousel video ad sizes

• Display size: 1080 x 1080 pixels or larger
• Aspect ratio: 1:1 (4:5 is supported only for Advantage+ catalog carousel ads)
• File type: MP4, MOV, GIF
• Maximum file size: 4GB
• Maximum video length: 240 minutes

Facebook Stories ad sizes

Facebook Stories ads appear between organic Stories as users scroll through their friends’ Stories.

You can place either an image or video Stories ad and link it to a website. Video Story ads play 10 seconds at a time. Image Story ads show for five seconds, unless someone swipes away sooner. These same specs also apply to Messenger Stories placements, so you don’t need separate assets. Because this is a 9:16 format, keep your CTA buttons and key visuals within the center 1080 x 1420 area so UI elements at the top and bottom don’t cover them.

Facebook Stories image ad sizes

• Display size: 1440 x 2560 pixels
• Minimum width: 500 pixels
• Aspect ratio: 9:16
• File type: PNG or JPG
• Maximum file size: 30MB

Facebook Stories video ad sizes

• Display size: 1440 x 2560 pixels
• Minimum video ad width: 250 pixels
• Aspect ratio: 9:16
• File type: MP4, MOV, GIF
• Recommended video settings: H.264 compression, square pixels, fixed frame rate, progressive scan and stereo AAC audio compression at 128kbps+
• Maximum file size: 4GB
• Maximum video length: 2 minutes, though Facebook will only fully show video ads that are 10 seconds or less. Video ads longer than 10 seconds will be broken up into multiple Stories cards—up to three. After three Stories cards, users will be prompted to Play Full to see the rest of the video.

Facebook Reels ad sizes

Promote an existing Reel or create an ad-specific one to be inserted between organic Reels as users scroll the Reels section on desktop or mobile. The only difference between a regular Reel and an ad is that on Reels ads, you can include a call to action button with a link.

Image ads can also be used as an overlay ad that appears at the bottom of an organic Reel as users watch. It’s a small image with ad copy next to it, so make sure to choose an image that stands out. As with Stories, watch your safe zones: UI overlays cover roughly the top and bottom 250px of a 9:16 Reel, so keep important text and visuals centered.

Facebook Reels image ad sizes

• Display size: 1080 x 1080 pixels or larger
• Minimum width: 600 pixels
• Aspect ratio: 1.91:1 to 1:1
• File type: PNG or JPG
• Maximum file size: 30MB

Facebook Reels video ad sizes

• Display size: 1440 x 2560 pixels
• Aspect ratio: 9:16
• File type: MP4, MOV, GIF
• Recommended video settings: H.264 compression, square pixels, fixed frame rate, progressive scan and stereo AAC audio compression at 128kbps+
• Maximum file size: 4GB
• Maximum video length: No maximum limit

Facebook in-stream video ad sizes

In-stream video ads “pop in” during organic video content and play at the start, during, or after another video, including in live streams. You can have a shorter, non-skippable ad, or choose to have a longer, skippable one, where the user can tap to close it after the first five seconds.

Facebook in-stream video ad sizes

• Display size: 1080 x 1080 pixels or larger
• Aspect ratio: 16:9 or 1:1
• File type: MP4, MOV, GIF
• Recommended video settings: H.264 compression, square pixels, fixed frame rate, progressive scan and stereo AAC audio compression at 128kbps+
• Maximum video file size: 4GB
• Maximum video length (desktop): Between 5 and 15 seconds
• Maximum video length (mobile): Between 5 seconds and 10 minutes

Facebook collection ad sizes

Facebook Collection ads look like carousel ads (because they are) but they’re a bit different as they’re automatically generated from your e-commerce product catalog, which you can add and manage in Commerce Manager.

You can also manually choose products from your connected catalog to put together specifically-targeted collection ads. Collection ads use product images or videos in a square (1:1) aspect ratio. You can upload other sizes, but they’ll be cropped to 1:1.

When someone taps a product in your collection ad on a mobile device, they see a full-screen view of your products, called an Instant Experience. It’s like a mini storefront.

Source: ohora.usa

On desktop, collection ads function as carousel ads, linking you over to that product’s page on your website (or other URL you’ve specified). You may recognize many of these details from the carousel ad specs.

Facebook feed collection ad sizes

• Display size: 1080 x 1080 pixels or larger
• Aspect ratio: 1:1
• File type: PNG or JPG (image), MP4, MOV, GIF (video)
• Maximum file size: 30MB (image), 4GB (video)

Facebook Reels and video collection ad sizes

These feature up to four products at the bottom of a Facebook Reel or video ad. For this video format, you’ll need a 9:16 video, like any other Facebook Reel you’d upload, plus an Advantage+ product catalog, which is automatically synced from Shopify, WooCommerce, Big Commerce, or several other partners.

Source: Meta Business

• Display size (image): 1080 x 1080 pixels or larger, 1:1 aspect ratio, PNG or JPG, 30MB max
• Display size (video): 1080 x 1920 pixels or larger, 9:16 aspect ratio, MP4, MOV, GIF, 4GB max

Facebook Marketplace ad sizes

Facebook Marketplace ads are an image-only format across desktop and mobile and, of course, are shown in the Marketplace tab. However, they also show up in the feed and across Facebook since they use Facebook’s automatic Advantage+ placement algorithm to match your ad with people who are most likely to buy.

Their primary purpose is to sell products and convert those in your target audience who are already looking to buy something. Marketplace ads always have a “sponsored” label alongside them.

Facebook Marketplace image ad sizes

• Display size: 1080 x 1080 pixels or larger
• Aspect ratio: 1:1
• File type: PNG or JPG
• Maximum file size: 30MB

Additional Facebook ad placements

These placements are more niche, but they’re worth knowing if you want full coverage across Meta’s network. Here are the specs for the smaller, secondary placements.

Facebook right-column ad sizes

Right column ads are a desktop-only Facebook ad format best for driving traffic or raising brand awareness. These are image-only ads, paired with a headline and link. Because it’s such a small ad visual, Facebook recommends against using any text or copy on your image file.

Source: Hooks & Needles and Hydroflask

• Display size: 1080 x 1080 pixels or larger
• Minimum width: 254 pixels
• Minimum height: 133 pixels
• Aspect ratio: 1:1
• File type: PNG or JPG
• Maximum file size: 30MB

Facebook search results ad sizes

Search results ads appear on, predictably, the search results page. These can perform very well if your targeting aligns with a user’s intent.

For example, my search for “planner” yields an ad from a planner company. Because I’m already searching for something related, it increases the chances of me clicking on this ad to learn more about the company and its products. Facebook search results are a great way to promote products, events, services, and more.

• File type: PNG or JPG (image), MP4, MOV, GIF (video)
• Maximum file size: 30MB (image), 4GB (video)
• Maximum video length: 241 minutes

Facebook Business Explore ad sizes

Business Explore shows up when someone taps an organic post from a business on a mobile device only. Scrolling down, they may see a heading to Explore more (the category the business they’re viewing is in). This shows a mix of organic and paid content from similar businesses.

Source: Meta Business

• Display size: 1080 x 1080 pixels or larger
• Minimum width: 600 pixels (image), 120 x 120 pixels (video)

• Maximum file size: 30MB (image), 4GB (video)
• Maximum video length: 241 minutes

Audience Network ad sizes

Meta’s Audience Network extends your ads to apps and sites outside of Facebook and Instagram. It supports a few distinct formats, so match your creative to the placement type.

• Banner: 320 x 50 pixels, PNG or JPG, 30MB max
• Interstitial: 320 x 480 pixels (vertical) or 480 x 320 pixels (horizontal), PNG or JPG for images (30MB max) or MP4/MOV for video (4GB max)
• Native: flexible sizing that adapts to the host app’s layout; supply a 1080 x 1080 pixels or larger asset (1:1) so it renders cleanly, PNG or JPG (30MB) or video (4GB)

FAQ: Facebook ad sizes

What’s the best size for a Facebook ad?

The best all-purpose Facebook ad size is 1080 x 1080 pixels (1:1 aspect ratio), which works across Feed, Marketplace, carousel, search results, and right-column placements. It crops predictably everywhere, so it’s the safest choice if you can only make one asset.

What size are Facebook ads in 2026?

Facebook ad sizes in 2026 remain consistent with recent years: 1080 x 1080 pixels for square placements, 1080 x 1350 for 4:5 Feed ads, and 1080 x 1920 pixels for vertical Stories and Reels.

What size is a 9:16 Facebook ad?

A 9:16 Facebook ad is 1080 x 1920 pixels, used for full-screen vertical placements like Stories and Reels. Keep key visuals centered so UI overlays don’t cover them.

Is 1:1 or 4:5 better for Meta ads?

For mobile Feed ads, 4:5 aspect ratio (1080 x 1350 pixels) is better because it occupies more screen space, but 1:1 (1080 x 1080 pixels) is the safer choice when your ad runs across multiple placements.

What are the Facebook ad formats?

Facebook supports image, video, carousel, collection, and Instant Experience ad formats, each available across multiple placements like Feed, Stories, Reels, Marketplace, and in-stream video.

What is the maximum Facebook ad image file size?

The maximum file size for a Facebook image ad is 30MB across all placements.

What is the maximum Facebook ad video file size?

The maximum file size for a Facebook video ad is 4GB across all placements.

What’s the difference between Facebook and Meta ad sizes?

There is no difference. “Facebook ad sizes” and “meta ad sizes” refer to the same specs, since Facebook is a product within Meta’s family of apps.

What aspect ratio should I use for Facebook carousel ads?

The recommended aspect ratio for Facebook carousel ads is 1:1 (square), with a minimum resolution of 1080 x 1080 pixels per card. A 4:5 ratio is also supported but currently only for Advantage+ catalog carousel ads.

Do Facebook ads need to follow a text limit on images?

Meta no longer enforces the 20% text rule, but ads with less text on the image still tend to perform better and receive broader delivery.

Ideal social media post length for every platform

Key takeaways

1. Shorter posts consistently outperform longer ones on most platforms, but the ideal length varies by network and content type (organic vs. paid).
2. Staying within recommended lengths (not just character limits) helps you avoid truncation, improve readability, and work with platform algorithms rather than against them.
3. The quick-reference cheat sheet below gives you every platform’s ideal social media post length at a glance, with detailed breakdowns for each network further down.
4. Test these benchmarks against your own analytics, because your audience may respond differently than the average.

Why social media post length matters

Social media post length shapes how many people see and interact with your content.

Most platforms cut off longer posts behind a See More button. That extra tap costs you readers, and fewer readers means fewer likes, comments, and shares, which are exactly the signals algorithms use to decide who else sees your post.

Here’s why keeping an eye on character count pays off:

• Algorithm visibility: Higher engagement tells the algorithm your content is worth surfacing to more people.
• Readability: The longer someone reads, the harder their brain works to process the message. Concise copy is easier to consume.
• Mobile experience: Most people scroll on their phones, where long blocks of text and truncated captions are easy to skip.
• Message clarity: Tighter posts force you to lead with your point instead of burying it.
• Shareability: Punchy, quick-to-grasp posts are more likely to get reshared.

Video follows the same logic. If you want a deeper dive on that, here’s our full guide to social media video length.

Social media post length cheat sheet

The ideal Facebook post length

While you have enough space to craft a short novella on FB — where 37% of U.S. adults scroll several times daily — shorter posts usually receive more likes, comments, and shares.

People like it when a message makes its point quickly and concisely. It’s satisfying, it tracks with current social trends, and it’s still Meta’s own guidance heading into 2026: lead with your key message so it lands before anyone has to tap See More.

Organic Facebook post length: 1 to 80 characters

The foundational research here is a few years old, but it still holds up against what Meta recommends today.

In 2016, BuzzSumo analyzed more than 800 million Facebook posts. Based on their findings, posts with less than 50 characters “were more engaging than long posts.” According to data published by Jeff Bullas (sourced from Buddy Media research), posts with 80 characters or fewer receive 66% higher engagement.

Two things explain this. First, Facebook cuts off longer posts with an ellipsis, forcing users to click See More to expand the text. That extra step reduces engagement, because every time you ask the audience to take action, a percentage of people lose interest. Second, shorter content demands less work to read and understand, and content that’s easy to consume enjoys higher engagement rates.

Facebook ad copy length: 5 to 19 words

Every Facebook ad in Meta Ads Manager has three main copy fields: primary text, headline, and description.

After analyzing 752,626 Facebook ads back in 2018, AdEspresso found that the most common copy lengths among successful ads were clear and concise. According to the data, the typical length for a:

• Headline, the first text people read, is 5 words (median).
• Primary text (the copy above the ad) is 19 words (average).
• Description (which appears below the headline) is 13 words.

Here’s a great concise example from AirBnb. No words wasted here.

The bottom line: whether the post is organic or paid, brevity drives engagement. A Facebook post generator can help you draft tight copy that stays within the sweet spot.

Capitalize on this by keeping your ad copy concise: don’t use two words when one will do. And keep it clear: omit adverbs, jargon, and the passive voice from your copy.

Facebook video length: 30 to 60 seconds

Sure, you can upload a 240-minute video to Facebook, but will anyone actually watch it all the way through? With video length, one of the primary measures of success is how long people watch, also known as your video retention rate.

For viral content, Facebook recommends videos that are less than one minute, or stories that are less than 20 seconds in length.

That said, if you’re hoping to qualify for in-stream ads, you might want to linger a little longer. Videos need to be over three minutes to qualify.

Facebook also recommends videos over three minutes for episodic series, live streaming, or story development.

The ideal Instagram post length

Unlike Facebook and X, Instagram was founded on visual content. The platform was made to showcase pictures and videos, but the right combination of words will promote engagement on any post.

Engagement is what maximizes your content’s reach, since Instagram’s algorithm places posts with the most likes and comments near the top of your followers’ feeds.

Organic Instagram caption length: 138 to 150 characters

A successful Instagram caption adds context, shows off your brand’s personality, entertains audiences, and compels your followers to take action.

The Instagram caption length limit is 2,200 characters. But you’ll only need a fraction of that to move the needle (as our very scientific experiment about caption lengths can attest).

Most people scroll through their feed quickly, so it makes sense to keep your captions clear and punchy. The same applies to carousel posts: front-load the context that hooks people into swiping. Brief copy is easy to consume, and it doesn’t get cut off with an ellipsis. Need some writing inspo? Find 311 creative Instagram captions to get you started right here.

Sponsored Instagram caption length: 125 characters or less

Instagram recommends keeping the captions on sponsored posts under 125 characters.

Again, this length supports readability and ensures that the text won’t get truncated.

Looking for more inspiration? Here are 53 examples of amazing Instagram ads.

Instagram Reels and Stories length: 15 to 60 seconds

Most people will watch your Instagram content on their phones, so following mobile-first best practices is important if you want to keep the viewer’s attention.

Stories max out at 15 seconds per frame, and Meta notes that people consume Stories much faster than other content, so capture attention right off the bat.

Reels can now run up to 3 minutes for most accounts, with some creators getting even longer. In 2026, Reels between 15 and 60 seconds tend to earn the strongest engagement, while shorter Reels under 15 seconds still work well as hooks. Whatever length you choose, get to the point quickly.

Find more best practices for Instagram ads here.

Instagram hashtags: 3 to 5 per post, at fewer than 24 characters each

Instagram posts can have up to 30 hashtags, making it tempting to stuff each caption with as many as possible. As a marketer, fight this urge. Using more hashtags won’t necessarily yield higher visibility, so use a hashtag generator to pick targeted tags rather than maxing out your count.

In fact, Instagram revealed that 3-5 hashtags will actually get you the best results, and our own little experiment confirmed just that.

Of course, picking the right hashtags to use is a whole other story. Our guide to Instagram hashtags will walk you through your options.

The ideal TikTok video length

People have downloaded TikTok more than 3 billion times, which means you’ve got a lot of short attention spans out there to appease.

For most users, the max video length on TikTok is 10 minutes, though the platform has experimented with lengths of 20, 30, and even 60 minutes. TikTok also added text-based posts, but video is still king here.

Just because you can do something doesn’t mean you should. On TikTok, the right length depends on your goal.

Organic TikTok video length: 15 to 60 seconds

The old advice was to keep everything ultra-short, but TikTok’s algorithm now rewards watch time, so a strong 30- to 60-second video can outperform a rushed 10-second one. Aim for 15 to 60 seconds, and lead with a hook in the first second.

The more people who watch and like your video, the more likely you are to appear on someone else’s For You Page, so it’s worth knocking it out of the park. (For more on appeasing the great TikTok algorithm, click here.)

Short-and-snappy still works, too. TikTok’s 7-second challenge is a proven tactic. When our social team tried it, their video pulled in half a million views, which is not too shabby at all.

TikTok ad length: 21 to 34 seconds

For top performance of ads, TikTok recommends 21-34 seconds.

But of course, length isn’t everything: content and quality formatting matter, too. We’ve got the rundown of everything you need to become a TikTok ads master right here.

Ideal LinkedIn post length

More than 1 billion professionals use LinkedIn, and as the platform’s user base grows, it becomes harder to win organic attention. Marketers must keep optimizing messaging for quality and timing as well as length. LinkedIn now supports carousels (document posts) — averaging 7.00% engagement — newsletters, and longer native text posts, so you have more formats to work with than ever.

Organic and paid LinkedIn post length: under 150 characters above the fold

As with other social updates, it’s best to keep LinkedIn posts short at the top.

The LinkedIn post length limit is 3,000 characters, but your text gets cut off behind a See More button after around 140 characters, like Shopify’s ad here did.

As a general rule of thumb, Hootsuite makes sure the key message is clear within the first 150 characters, so the most important part of your post lands before anyone has to expand it.

LinkedIn article and newsletter length: 1,900 to 2,000 words

Paul Shapiro, founder of Search Wilderness, analyzed more than 3,000 of the most successful posts on LinkedIn’s publishing platform. These posts, on average, received 42,505 views, 567 comments, and 138,841 likes.

He discovered that articles with more words perform better.

“Posts between 1900 and 2000 words perform the best,” writes Shapiro. “[They] gain the greatest number of post views, LinkedIn likes, LinkedIn comments, and LinkedIn shares.”

Shapiro also learned that the ideal LinkedIn character limit for titles is between 40 and 49 characters. Titles in this range received the greatest number of post views overall. The same long-form logic applies to LinkedIn newsletters, which give you a subscriber base and land directly in inboxes.

LinkedIn video length: 30 to 90 seconds

LinkedIn lets users natively upload videos that play automatically in their followers’ feeds. Unlike other platforms, LinkedIn also shares video data (e.g., viewers’ companies and job titles), making it a valuable resource for marketers.

According to LinkedIn, the most successful video ads are under 30 seconds long. Lengths can vary for native LinkedIn video, though.

For brand awareness and brand consideration videos, LinkedIn recommends keeping the length under 30 seconds — short videos achieve 200% higher completion rates than longer formats.

Videos that meet upper-funnel marketing goals should stick to a 30- to 90-second length.

The ideal length of a post on X

So, how many characters are in an X post (formerly known as a tweet)? Back in 2017, Twitter doubled its character limit from 140 to 280 to make writing on the platform easier. X Premium subscribers can now go far longer, up to 25,000 characters, but just because you have the room doesn’t mean people want to see you use it.

Organic and promoted X post length: 71 to 100 characters

The go-to data here comes from Buddy Media, which found that X posts containing less than 100 characters receive, on average, 17 percent higher engagement than longer ones. That study is old, but the principle still tracks in 2026: shorter posts are easier to read and comprehend, and they perform.

Even with X Premium’s extended limits, long-form posts tend to work best for threads or deep-dives, not everyday updates. Using a link shortener can also buy back a few precious characters.

X hashtag length: 6 characters

“The best hashtags are those composed of a single word or a few letters,” writes Vanessa Doctor from Hashtags.org. “Experts recommend keeping the keyword under 6 characters.”

Again, this length is about reader comprehension, especially since hashtags don’t support spaces. A social media hashtag generator can suggest concise options that are easy to scan and remember.

The ideal length for YouTube posts

At the end of the day, YouTube is a search engine, meaning it relies on text to organize and rank the nearly 500 hours of video uploaded to its servers every minute.

So in addition to optimizing video length, marketers must front-load their title and description copy with relevant keywords, and that means keeping an eye on character count.

YouTube long-form video length: 7 to 15 minutes

Whether you’re watching videos on YouTube or anywhere else, one of the most important KPIs is retention.

How long do people actually watch? Are viewers finishing your videos at a high rate? If so, you’re doing something right.

Statista reports that the average video is 11.7 minutes long, and Social Media Examiner endorses this as the ideal, writing that videos between 7 and 15 minutes have the best performance.

Of course, there’s more to a successful YouTube strategy than the right length. Here’s everything you need to know about creating great YouTube content for your business.

YouTube Shorts length: 30 to 60 seconds

YouTube Shorts have their own rules. As of late 2024, Shorts can run up to 3 minutes, but shorter Shorts in the 30- to 60-second range tend to earn more replays, and replays are a strong signal for the Shorts feed.

Treat Shorts like TikToks or Reels: hook viewers in the first second, keep the pacing tight, and give them a reason to loop back to the start.

YouTube title and description length

The most important SEO factor for YouTube is the title of your video. Include relevant keywords so you reach high rankings in Google and YouTube search, while being compelling enough to encourage clicks and views.

Keep your title to 70 characters maximum so it doesn’t get cut off, per Influencer Marketing Hub. Need help? Our free YouTube title generator will do it for you.

For descriptions, the first 100 to 150 characters appear under your video, so optimize that chunk with both rich detail and intriguing keywords. Hone your description skills with our YouTube caption guide or head straight to our AI-powered YouTube video description generator.

Threads post length

Threads, Meta’s text-first app, has grown into a serious channel with over 500 million monthly active users as of mid-2026. If you already post on Instagram, it’s an easy place to extend your conversation.

Ideal Threads post length: under 200 characters

Threads posts have a 500-character limit, but the platform is built for quick, conversational back-and-forth, so you rarely need all of it. Early engagement patterns favor posts under 200 characters, which read easily and invite replies. An AI caption generator can draft punchy options that fit within that range.

Threads doesn’t use traditional hashtags. Instead, you can add a single topic tag per post to join a conversation. Lead with a clear point or a question, keep it casual, and let the replies do the heavy lifting.

The ideal size and length for Pinterest posts

On Pinterest, image size matters. So does the length of your description.

Pinterest images: 1000 x 1500 pixels

According to Pinterest best practices, images on the platform should have a 2:3 aspect ratio, which is how the height and width of an image relate.

Description length: 300 characters

According to Social Marketing Writing, descriptions containing about 300 characters receive the most repins. (For more juicy numbers, check out our guide to must-know Pinterest stats here.)

Your Pinterest caption is your chance to add context and persuade readers to act. It’s where you tell a story and make a promise. The same goes for Idea Pins, the multi-page video format: keep each page’s text short so viewers stay through to the end.

A well-written description is also an opportunity to get discovered, so make sure to brush up on your Pinterest SEO best practices.

Careful! Don’t go over the limit:

The ideal length of Snapchat videos and captions

Given how brief the limits are on Snapchat captions and videos, it’s almost impossible to go too long.

To thrive with engagement on this platform, it’s more about what you’re posting than how long that content plays for.

Ideal Snapchat Story length: 15 seconds

Snapchat Story videos can be up to 60 seconds long, but it’s rare for engagement to stay high across those longer pieces of content.

Instead, aim for (we’ve said it before, and we’ll say it again!) short-and-sweet videos that hit hard off the top, like this hot sauce ad, which clocks in at just 20 seconds but makes a serious impact.

New to Snapchat? Here’s our guide to Snapchat for Business for beginners.

Ideal Snapchat video caption length: 50 characters

Captions for snaps can be up to 80 characters, but they’re really secondary to the visual content, so don’t stress too much about making the most of this.

Tips for optimizing your social media post length

These benchmarks are a strong starting point, but the best post length for engagement is the one your audience actually responds to. Here’s how to dial it in:

1. Use your analytics to find what works. Check which of your past posts performed best — an engagement rate calculator makes this quick — and note their length. Patterns will emerge faster than you’d think.
2. Run A/B tests. Try running A/B tests to see whether the suggested character counts in this guide really are ideal for you.
3. Front-load your message. Put your key point before the See More cutoff so it lands even if no one taps to expand.
4. Preview before you publish. Use a caption preview tool or a scheduler like Hootsuite to see exactly how your post will appear on each platform before it goes live.
5. Revisit quarterly. Platforms update their algorithms and formats constantly, so check your length strategy every few months.

FAQ: Ideal social media post length

What is the ideal social media post length?

The ideal post length depends on the platform, but shorter posts generally outperform longer ones: aim for under 80 characters on Facebook, 138 to 150 on Instagram, 71 to 100 on X, and under 150 characters above the fold on LinkedIn.

Should social media ad copy be shorter than organic posts?

Yes, ad copy should generally be shorter and more direct than organic posts, because paid content competes for attention in crowded feeds and needs to communicate value within the first few words before users scroll past.
