Platforms change these details now and then. We updated this list in November 2026; before a big campaign it's worth a look at the platform's own help page.
- Reels: 9:16, 1080 × 1920.
- Stories: 9:16, 1080 × 1920.
- Feed post, portrait: 4:5, 1080 × 1350. Instagram also accepts 3:4 (1080 × 1440) portrait posts, and the profile grid now shows posts at 3:4.
- Feed post, square: 1:1, 1080 × 1080.
Portrait posts take up the most room in the feed. A square post uses less of the screen than a portrait one.
TikTok
- Video: 9:16, 1080 × 1920.
You can upload landscape video, but most of the screen stays empty. You'd need a good reason to use anything but vertical on TikTok.
YouTube
- Regular video: 16:9, 1920 × 1080 or 3840 × 2160.
- Shorts: 9:16, 1080 × 1920.
LinkedIn and X
- LinkedIn: 1:1, 4:5 and 16:9 all look good in the feed; vertical video may be cropped to something close to 4:5 on mobile.
- X (Twitter): 16:9 and 1:1 are the safest.
Where to put text
In vertical video the bottom of the screen is covered by likes, comments and the caption, and the right edge holds the buttons. Keep important text and the device's screen inside this area:
- About 250 pixels clear at the top.
- About 400 pixels clear at the bottom.
- About 150 pixels in from the right edge.
That's a rough safe zone rather than a rule. The apps move things around with each update, but these margins work on Reels, TikTok and Shorts alike.
Every size from one project
Rebuilding the video for each platform isn't necessary. Set up the scene once and export it in different frames. In Mockup Center you switch the frame to 9:16, 4:5, 1:1 or 16:9 and nudge the device and camera into place, so a vertical Reel and a horizontal YouTube video come from the same project.
In a vertical frame it helps to keep the device a little smaller. That leaves room for a headline above it and the platform's buttons below.
