TikTok Aspect Ratio - Exact Size & Safe Zones

TikTok's 9:16 full-screen format and the safe zones the UI covers.

Quick answer: TikTok is 9:16 vertical at 1080×1920 - the only ratio that fills the screen. Keep captions and key action out of the top ~10% and bottom ~20%, where the interface and caption text sit.

Pick or enter a ratio, give the one side you know, and get the other side.

What is TikTok Aspect Ratio?

TikTok is a full-screen vertical platform: the native format is 9:16 at 1080×1920 pixels, and that is the only shape that fills a phone edge to edge. Anything uploaded in 16:9 or 1:1 plays inside black bars, which reads as repurposed content and reliably underperforms. Beyond the ratio, TikTok design is about the safe zones - the username, caption, music attribution and interaction buttons overlay the top and bottom of the frame, so text, faces and key action belong in the middle band of the picture.

Common Uses for TikTok Aspect Ratio

  • Export native TikTok videos at 1080×1920
  • Place captions where the UI will not cover them
  • Reframe horizontal footage into a vertical centre-crop
  • Design covers that read at grid size

Designing inside 1080×1920

Treat the frame as three bands: an unsafe top strip, an unsafe bottom strip, and a free middle. Practice: put on-screen text centred around the vertical middle, faces in the upper-middle third, and end cards inside the middle 70%. When repurposing from YouTube, the fastest path is not a crop but a re-edit: 9:16 rewards close-ups, big type and vertical pacing, while a letterboxed upload signals 'cross-post' and gets swiped past.

Frequently Asked Questions

What resolution does TikTok use?
1080×1920 (9:16). Uploads at this size play full-screen with no processing surprises; larger vertical sizes are downscaled, and non-vertical sizes are letterboxed.
Can I post a 16:9 video on TikTok?
It uploads, but it plays as a small letterboxed strip - viewers see black above and below. For reach, reframe to 9:16: either a centre crop (a 16:9 frame keeps only 31% of its width) or a padded vertical canvas with blurred footage behind.
Where are TikTok's safe zones?
Roughly: the top 10% carries status icons, the bottom 20% carries the caption, username and music title, and the right edge carries the interaction rail. Keep essential text and action inside the central 60-70% of the frame.
Do TikTok photos use a different ratio?
Photo-mode posts display at 9:16 too; images in other ratios are shown with padding. 1080×1920 works for both video and photo posts.
