Facebook Video Ad Size 2026: Pixels and Ratio by Placement

You finished a video for your business, and now Facebook wants to know what shape it is. The right Facebook video ad size depends on where the ad plays, so one number will not cover it.

For a Facebook video ad, Meta's Ads Guide lists 4:5 at 1440 x 1800 pixels for Feed, and 9:16 at 1440 x 2560 pixels for Reels and Stories. In-stream takes 16:9 or 1:1, at no less than 1080 x 1080 pixels. Each of these placements accepts files up to 4 GB.

If you would rather not deal with sizes at all, our team can make the ad for you. A 30-second Claymation Ad is $97 one-time, often half price in our holiday sales. We write it and make it, you approve every word and every scene, and it comes in vertical size for Reels and Stories.

Want to do it yourself? That's fine too. We opened Meta's own pages on November 6, 2026, and the specs below come from them, with a link to each page.

Key takeaways

• Meta's Ads Guide lists 4:5 at 1440 x 1800 pixels for Facebook Feed.
• Reels and Stories both list 9:16 at 1440 x 2560 pixels.
• Meta's ratio table has no check mark for 9:16 on Facebook Feed.
• In Stories, a video over 15 seconds gets split into cards.
• On a vertical ad, keep words out of the top 14% and the bottom 35%.

What is the Facebook video ad size for each placement in 2026?

The Facebook video ad size changes with the placement, which is the spot where your ad shows up, like Feed or Reels. Meta's Ads Guide recommends 4:5 for Feed and 9:16 for Reels and Stories.

Aspect ratio is the shape of the video, written as width to height. So 9:16 is tall, 1:1 is square and 16:9 is wide.

Here are the video specs and dimensions from each page of Meta's Ads Guide, as listed on November 6, 2026. The last row shows what we deliver through Ad Factory, our done-for-you ad team.

Meta's pages show these specs with the Awareness objective selected, and the in-stream page says length limits may vary by objective.

A plumber who wants one ad on phones hits a snag here: Feed and Reels ask for different shapes.

Can a 9:16 vertical video run in Facebook Feed?

Meta's ratio table has no check mark for 9:16 on Facebook Feed. Its Aspect ratios supported by placements page checks 1.91:1, 16:9, 1:1 and 4:5 for Feed, with 4:5 recommended for images and videos. The same table does check 4:5 for Reels and Stories, though 9:16 is the shape it recommends there.

Meta's best practices for aspect ratios says your media is automatically adjusted to fit more placements. If you don't supply all four shape variations, it fills the gaps with padding, media expansion, cropping and other AI-enabled features.

Our clay ads come in vertical size, which fits Reels and Stories. We do not supply a 4:5 cut for Feed.

If you run a vertical ad with Feed switched on, look at what Meta Ads Manager (the tool where you set up your ads) made of it before you publish. Meta's page says to review auto-generated crops so nothing important gets cut off. If you want a video to run only in certain spots, Meta says to turn off the other placements (it calls these placement opt-outs).

Here is a sample we made for a made-up plumber, in the same tall shape.

Why does a Facebook Feed video ad get black bars on a computer?

Facebook Feed shows video at 1:1 on the computer version, even when you upload 4:5. Meta says this "may cause black bars to appear on either side of the video" on its ratio page. The same note appears on its troubleshooting page.

So black bars on a laptop don't always mean your file is wrong. Check your ad on a phone as well, because the phone view is a different shape.

What is the safe zone on a Facebook Reels or Stories ad?

The safe zone is the part of a vertical ad that stays clear of Facebook's icons and buttons. On Reels and Stories ads, Meta suggests keeping about 14% of the top, 35% of the bottom and 6% of each side free of text and logos. The Facebook Reels page gives this advice so your profile icon and call-to-action button (the tap button on the ad) don't sit on top of your words. The Stories page gives the same three numbers.

Percentages are hard to use in an editor, so here they are in pixels on a 1440 x 2560 video. We did this math ourselves from Meta's percentages.

• Top: leave about 358 pixels clear.
• Bottom: leave about 896 pixels clear.
• Each side: leave about 86 pixels clear.
• What's left: an area about 1268 pixels wide and 1306 pixels tall for your words and logo.

That bottom number is the big one. More than a third of the screen is best left clear, so a phone number at the very bottom of the frame can end up under a button.

Meta adds one more note on its ratio page. On screens taller than 9:16, it may zoom the video, which can crop areas outside the safe zone, or show the video at 9:16 on a black background.

What happens to a 30-second video ad on each Facebook placement?

A 30-second video ad runs as one video on Facebook Feed and Reels. Stories splits it into cards, in-stream on mobile cuts it off after 15 seconds, and it is too long for in-stream on desktop and for Ads on Facebook Reels.

• Facebook Reels: the Ads Guide lists no maximum, so length is not a limit here.
• Facebook Stories: videos of 15 seconds or less play in full. Longer videos get split into separate cards, and Facebook shows 1, 2 or 3 cards before offering Play Full. That includes our 30-second clay ad, so on Stories it shows as cards.
• In-stream on desktop: the limit is 5 to 15 seconds.
• In-stream on mobile: the limit is 5 seconds to 10 minutes. Videos over 15 seconds show the first 15 seconds and then cut off, and viewers can click a card under the main video to keep watching. Ads may also be skippable after the first 5 seconds.
• Ads on Facebook Reels: the limit is 15 seconds, so a 30-second video is too long for this one.
• Facebook Feed: the limit is 241 minutes, so 30 seconds fits easily.

For how long your ad should be, see our guide to how long a Facebook video ad should be.

Why do Facebook ad size guides list different numbers?

Facebook ad size guides don't always match Meta's Ads Guide, and specs can change between updates. That's why this post links every number to the page it came from.

Here are four differences we found on November 6, 2026:

• Pixels: QuickFrame's March 2026 guide gives 1080 x 1920 for Stories. Meta's Ads Guide lists 1440 x 2560. Both are the same 9:16 shape.
• Reels length: that same guide gives 4 to 15 seconds for Reels. Meta's Reels page lists no maximum. The 4 to 15 second range matches Meta's separate Ads on Facebook Reels placement.
• Stories cut-off: Hootsuite's July 2026 guide says Facebook fully shows Stories ads of 10 seconds or less. Meta's Ads Guide says 15 seconds.
• Safe zone: QuickFrame's guide says to keep about 250 pixels clear at the top of Stories and about 340 at the bottom. Meta's 14% and 35% on a 1920-tall video come to about 269 and 672 pixels. Trust the larger bottom number, or your words can sit under the button.

Meta's own pages don't always match each other either. Its Ads Guide gives Stories a length of 1 second to 3 minutes, and its video length page says 1 to 120 seconds. Its ratio page marks 9:16 as recommended for Stories in the table, while the text under that table says 2:3.

When pages differ, go to the Ads Guide first, because Meta's help pages point you there for the correct ratio. Then check the preview in Ads Manager on the day you upload.

How do you check a Facebook video ad before you upload it?

Check six things before you upload a Facebook video ad, in this order: placements, ratio, length, file, safe zone and preview.

Step 1: Pick your placements

Choose where the ad will run before you export anything. A roofer who only wants Reels and Stories needs one tall file, not three.

Step 2: Match the ratio to the placement

Use 4:5 for Feed, 9:16 for Reels and Stories, and 16:9 or 1:1 for in-stream. Stories allows only 1% off the exact shape, so export it exactly.

Step 3: Check the length

Keep Stories to 15 seconds if you want the whole video to play without cards. Keep in-stream to 15 seconds for desktop.

Step 4: Check the file

Export an MP4 or MOV. The Ads Guide lists H.264 compression (the way the file is packed down), a fixed frame rate and stereo AAC audio at 128 kbps or more. Meta's troubleshooting page sets a 4 GB maximum for all videos.

Step 5: Move your words into the safe zone

Keep your words and logo out of the top 14%, the bottom 35% and 6% of each side. Do this on every vertical version.

Step 6: Preview before you publish

Open each placement in the Ads Manager preview, including phone and computer views. Meta's troubleshooting page says to preview the ad to check that it looks right.

If your goal is calls or bookings, check the footer too. With the Awareness objective (a campaign set up to get seen) or goals such as maximum reach, Meta says the footer does not show on Feed on mobile. That footer holds your headline, description and call-to-action button. A dentist who wants new patient bookings needs that button on screen.

Pro tip: Name each file with its shape, like spring-offer-9x16.mp4. Then you won't upload the wrong one to the wrong placement.

Who should make and size your Facebook video ad?

If you are busy running your business, our done-for-you team is the best option for making and sizing a Facebook video ad. Sizing is a small job, but it comes with the bigger job of writing and making the ad. So the question is how much of that work you want to do yourself.

With a tool, you do the work. With a marketplace gig, in our view quality is often low and uneven, and it takes a lot of back and forth. You are also not dealing with a professional marketing team.

30 Second Ad Factory is the done-for-you ad team at 30 Second Productions, and your clay ad is made in your own Ad Factory dashboard. You tell us about your business, then approve every word and every scene. You never write prompts, edit video or learn an app, and you can order more ads any time.

We make each clay ad with AI tools for the pictures, movement and voice, and our team checks every video before it reaches you. It's ready about 24 hours after you approve the scenes. You own the video, and we make the ad but do not run it for you.

Frequently asked questions

What is the best aspect ratio for a Facebook video ad?

Meta's Ads Guide recommends 4:5 for Facebook Feed and 9:16 for Reels and Stories. In-stream takes 16:9 or 1:1. If you only make one file, match it to the placement that matters most to you, then check the preview in Meta Ads Manager.

Is 1080 x 1920 okay for a Facebook video ad?

1080 x 1920 is the same 9:16 shape as the 1440 x 2560 that Meta's Ads Guide lists for Stories and Reels, with fewer pixels. It is well above the minimum width Meta's pages give. If you can export 1440 x 2560, use that, because it is the size Meta lists.

What file type does Facebook want for a video ad?

Meta's Ads Guide lists MP4, MOV or GIF for Feed, Reels, Stories and in-stream. Ads on Facebook Reels lists MP4 and MOV only. Meta also lists H.264 compression and stereo AAC audio.

Do I need a different video for each Facebook placement?

Not always, because Meta Ads Manager adjusts your media to fit more placements. Meta says you get more control by uploading specific shapes, such as a 9:16 file if Stories matters to you. For Feed plus Reels and Stories, Meta's recommended shapes are 4:5 and 9:16, so that means two files.

Are captions required on a Facebook video ad?

No, Meta's Ads Guide lists captions as optional but recommended on Feed, Reels, Stories and in-stream. It lists sound the same way, and strongly recommends it on Reels and in-stream. Our clay ads show every word on screen, so they work with the sound off.

Are Facebook Reels and Stories ads the same size?

Yes, Meta's Ads Guide lists both at 9:16 and 1440 x 2560 pixels. The difference is length. Stories splits videos over 15 seconds into cards, while Reels lists no maximum. Both pages ask you to leave the same areas clear of text.

The short version

For the right Facebook video ad size, use 4:5 at 1440 x 1800 pixels for Feed, 9:16 at 1440 x 2560 for Reels and Stories, and 16:9 or 1:1 for in-stream, then give the Ads Guide a quick look before you upload.

If you enjoy editing, that's a job you can do yourself. If you are busy running your business, our done-for-you team is the best option.
