Social media video sizes for every platform

Social media video sizes come down to four shapes. Vertical 1080×1920 (9:16) is used for Reels, Stories, TikTok, YouTube Shorts, Snapchat and WhatsApp Status. Portrait 1080×1350 (4:5) is the feed shape on Instagram, Facebook, Threads, X and LinkedIn. Square 1080×1080 (1:1) works almost everywhere as a fallback. Landscape 1920×1080 (16:9) is for YouTube, websites and screens. Export at those exact pixel sizes as MP4 and the platforms have nothing to crop or rescale.

Video sizes by platform

Notice how often the same few sizes repeat. A vertical video made for Reels also suits TikTok, Shorts, Snapchat and WhatsApp with no changes beyond checking where each app places its buttons. For still images on the same platforms, see social media image sizes.

Where a platform offers several shapes, choose by where the video will be seen. In a scrolling feed, portrait 4:5 takes the most room and is usually the better pick over square. On X and Bluesky, landscape 16:9 still sits naturally in the timeline, but a portrait 1080×1350 video takes more of a phone screen. Pinterest favours tall 2:3 pins, so a vertical design cropped to 1000×1500 usually works well there.

Length limits and file rules

Platforms change their maximum lengths, file sizes and frame rate rules regularly, sometimes more than once a year, and they vary by account type and region. Any list you read elsewhere is likely to be out of date somewhere. Check the source when it matters: Instagram Help, YouTube's recommended upload settings and X's video help are the places to look.

What doesn't change is the practical advice. Export MP4 with H.264 video, at the exact frame size, at a steady frame rate such as 30 fps, with good quality settings. Platforms re-encode everything you upload, so a clean, sharp original is the best way to make the compressed version look right. The format choice is covered in MP4 vs WebM.

Safe zones: where the app covers your video

Vertical apps draw their interface on top of the video: names and captions at the bottom, buttons down the right, progress bars and account details at the top. Your video still fills the frame, but anything placed under those overlays is hidden. Keep words, logos and faces in the centre of the frame and treat the edges as background.

Exact overlay positions differ between apps and move with redesigns. Social media safe zones keeps the current map, and Instagram Story size shows the bands for stories in pixels.

How to plan one video for every platform

1. 1

   Design the 9:16 version first

   It is the tallest and the one most platforms favour. Keep everything important inside the central square of the frame.

2. 2

   Derive 4:5 and 1:1 from it

   Because the key content sits in the centre, the feed versions are mostly a reframe rather than a redesign.

3. 3

   Make 16:9 separately when it matters

   Landscape is a different composition. For YouTube or a website hero, rearrange the words side by side instead of cropping.

4. 4

   Check each one at full size

   Look for words near the edges, a logo under the buttons and a background that now crops awkwardly.

5. 5

   Export each at its exact size

   Upload 1080×1920 to vertical formats and 1080×1350 to feeds, never one stretched into the other.

This is the part Gradiently takes off your hands. On Pro you can resize a design to every size in one step, and the Mark behind it is rendered fresh for each frame rather than cropped, so the calm area still lands behind your words in 9:16 and in 4:5. Then export each version as video. If your clips are mostly backgrounds with words, Reels and TikTok backgrounds has ideas to start from.
