Correct TikTok video dimensions, aspect ratios, and image sizes for maximum quality and reach on the platform.
TikTok is built around vertical full-screen video. Using the correct dimensions ensures your content fills the screen without black bars or cropping.
| Asset | Dimensions | Aspect Ratio | Notes | Copy |
|---|---|---|---|---|
| Video — Vertical Recommended | 1080 × 1920 px | 9:16 | Full screen, best performance | |
| Video — Horizontal | 1920 × 1080 px | 16:9 | Letterboxed on mobile | |
| Video — Square | 1080 × 1080 px | 1:1 | Pillarboxed on mobile | |
| Profile Picture | 200 × 200 px | 1:1 | Displayed as circle | |
| Cover Image | 1080 × 1920 px | 9:16 | Thumbnail shown in profile grid |
TikTok is designed as a mobile-first, full-screen vertical experience. Vertical 9:16 videos (1080×1920 px) fill the entire phone screen without any black bars. The algorithm strongly favors videos that use the full screen — horizontal videos shown with letterbox bars typically see lower completion rates and reduced algorithmic distribution. Always shoot and edit in 9:16 for TikTok content.
TikTok's UI overlays important areas of your video. The bottom ~300 pixels shows the username, video description, hashtags, and music information. The right side shows the like, comment, share, and follow buttons. Design with a central safe zone of approximately 1080×1420 px. Avoid placing important text or faces in the bottom 25% or right 15% of the frame.
The cover image is the frame shown in your profile video grid. You can select any frame from your video as the cover, or upload a custom image. Custom covers (1080×1920 px at 9:16) let you create a cohesive profile aesthetic. Many creators align cover images to form grid patterns or color themes on their profile page.
TikTok profile pictures display at 200×200 px. Upload a square image that looks clear at small sizes. The image appears as a circle on your profile page and as a small ring on your videos when they appear in the For You feed. Use a high-contrast image — a simple face or bold logo works better than complex photography at 200px.
Record in the highest resolution your device supports. Film in good lighting — TikTok's compression algorithm preserves well-lit content better than dark or grainy footage. Export at H.264 with a high bitrate before uploading. TikTok re-encodes all uploads, so starting from a high-quality source produces the best final result on the platform.
In 2026, the biggest avoidable mistake is placing captions or product text too low. TikTok’s bottom UI stack often covers more space than creators expect, especially on videos with long captions, Shop tags, or auto-generated subtitles. Keep key text and logos centered in the middle safe zone, and leave roughly the bottom 20% clear. Before posting, preview with captions turned on, because subtitle placement can hide call-to-action text that looked fine in your editor but gets blocked in the actual TikTok player.
