Vertical video specs 2026: sizes for every platform

One shape, four platforms, a few rules that differ.

Vertical video specs 2026 are simpler than they look: every major platform takes 9:16 video at 1080 x 1920 pixels, exported as an MP4 with H.264 video and AAC audio. What differs is the maximum length, the file size limit and where each app puts its buttons, so those are the parts to check per platform.

What are the vertical video specs for 2026?

The core spec is the same everywhere: a 9:16 frame at 1080 pixels wide by 1920 pixels tall. Meta, TikTok and YouTube all recommend it, and LinkedIn accepts it for vertical video ads.

Export as MP4 (MOV also works on most platforms), with H.264 video and AAC audio. Use a fixed frame rate, usually the rate you filmed at. In the UK that's commonly 25 or 30 frames per second. Going higher rarely helps on a phone screen and makes files bigger.

How do the platforms differ?

Mostly on length and on where the buttons sit. The table below covers the specs from each platform's own documentation at the time of writing. Each platform updates its guide, so treat this as a starting point and check before a launch.

What are safe zones, and why do they matter?

Safe zones are the parts of the frame that won't be covered by the app's own interface. Put text or a logo outside them and it can sit under the caption, the profile name or the like and share buttons.

Meta's Ads Guide is the most specific: for Reels ads it asks you to keep the top 14%, the bottom 35% and 6% on each side free of text and logos. For Stories, keep roughly the top and bottom 14% clear. TikTok and YouTube Shorts both place buttons down the right-hand side and captions at the bottom, so the same rule of thumb works there: keep anything important in the centre of the frame.

How do you set up a vertical video edit, step by step?

This is the order we work in, so one edit works on every platform.

  1. Film vertical where you can. Cropping landscape to vertical throws away most of the frame.
  2. If you have to crop, film landscape in 4K and frame the subject in the centre, so a 1080 x 1920 crop still looks sharp.
  3. Set the edit timeline to 1080 x 1920 at your filming frame rate.
  4. Place a safe zone overlay on the timeline before you add any text.
  5. Keep captions in the middle band of the frame, above the bottom caption area.
  6. Export MP4, H.264 video, AAC audio, at the same frame rate as the timeline.
  7. Check the file against the platform's length and size limits before upload.
  8. Watch the upload on a phone, in the app, before you post or launch the ad.

Should you also make square or 4:5 versions?

For ads, often yes. Some placements, such as the Facebook and Instagram feeds, show 4:5 or square video more cleanly than 9:16. If you plan for it at the edit stage, making extra shapes is quick: keep the subject and text near the centre and the crop takes care of itself.

For organic posts on Reels, TikTok and Shorts, 9:16 is the shape to use. Instagram also shows a 3:4 crop of Reels on your profile grid, so check the cover frame still looks right.

What usually goes wrong with vertical video uploads?

Nearly always one of these.

  • Text or a logo hidden behind the app's buttons or caption.
  • A landscape video dropped onto a vertical canvas, with black bars above and below.
  • A video uploaded after being sent through a messaging app, which compresses it.
  • A variable frame rate from a phone, which can cause stutter after upload.
  • A file over the size or length limit for that placement.

Vertical video specs by platform

From each platform's own documentation. Check the official guide before a big launch, because specs change.

How does Foundry handle video specs?

Every edit we deliver comes in the sizes each platform needs, with captions inside the safe zones, checked on a phone before it goes anywhere. We keep one master edit and cut the shapes from it, so a 9:16 Reel, a 4:5 feed ad and a landscape YouTube version all match.

We also run Meta, TikTok and LinkedIn ads, so we see when a platform changes its rules and update our exports before it becomes a problem.

Vertical video specs FAQs

  • 1080 pixels wide by 1920 pixels tall, a 9:16 frame. Every major platform recommends it.

  • 1080 x 1920 is one resolution at the 9:16 shape. You can export larger at the same shape, but 1080 x 1920 is what the platforms recommend.

  • Yes, if text sits in the centre of the frame and the video fits each platform's length limit. Upload the original file to each, rather than downloading and reposting.

  • Film in 4K if you want room to crop or punch in. Export at 1080 x 1920, which is what the platforms recommend and display.

  • MP4 with H.264 video and AAC audio. Every major platform accepts it.

  • Yes, especially maximum lengths and ad placements. Check the platform's own guide before a big launch.
