TikTok, Reels and Shorts video size and safe zones (2026)
Vertical 9:16 is the common format for TikTok, Instagram Reels and YouTube Shorts. The table below lists the dimensions and limits each platform publishes on its own help pages; every figure links to that page. Where a figure could not be sourced from an official page it has been left out rather than copied from blogs.

Safe zones
Each platform overlays UI (captions, profile, action buttons, progress bar) on top of the video. Keep logos, text and faces out of the bottom and right edges. Millwards Studio shows a safe-zone overlay in the editor; toggle it from the ratio bar.
