TikTok sizes, safe zones and text limits in 2026
TikTok is watched full-screen on phones, with the app's buttons and text sitting on top of your video. Getting the size right fills the screen; knowing the safe zone keeps your subtitles and faces from being hidden.
Sizes
| Video | 1080 × 1920 px (9:16) |
|---|---|
| Photo post | 1080 × 1920 px (9:16) for full-screen |
| Cover | 1080 × 1920 px. The profile grid shows a shorter crop, so keep the subject in the middle. |
| Profile photo | Square image shown as a circle |
Square (1:1) and horizontal (16:9) videos are accepted but play smaller, with bars. The TikTok Resizer converts any image to full-screen 9:16.
The safe zone
On a 1080 × 1920 frame, these areas are roughly covered by the app:
- Top, about 108 px: account details and tabs.
- Bottom, about 320 px: your username, caption and the sound name.
- Right, about 120 px: the like, comment, save and share buttons.
- Left, about 60 px: a small edge margin.
That leaves a clear area of roughly 900 × 1490 px in the middle. Put subtitles, product names and faces there. Instagram Reels and YouTube Shorts have slightly different margins. Check all three on a real frame with the Safe Zone Checker.
Text limits
| Caption | Up to 4,000 characters in the app, hashtags included |
|---|---|
| Photo post title | Up to 90 characters |
| Bio | 80 characters for most accounts |
| Username | Up to 24 characters: letters, numbers, underscores and periods |
| Display name | Up to 30 characters |
Many scheduling tools still limit captions to 2,200 characters, so keep long captions for posts you publish in the app.
Caption tips
- Lead with the hook. Only the first line or two show over the video.
- Write for search. People search TikTok like a search engine, so use the words they'd type.
- Use 3–5 relevant hashtags. Specific tags describe your video better than a long generic list.
Check every text field against the limits with the Caption & Bio Counter.
