Why TikTok sizes matter
TikTok is built around a full-screen 9:16 canvas, and the app overlays the caption, username, and action buttons on top of your video. Content that is not sized for that vertical frame gets cropped or pushed behind the interface. Getting the dimensions right keeps your hook, captions, and call to action visible to viewers.
TikTok content specificationsUpdated 2026
Video
Updated 2026TikTok video is vertical 1080x1920px (9:16) and can run up to 10 minutes. Keep important text and your subject in the central safe zone so the right-side buttons and bottom caption do not cover them.
Carousel
Updated 2026Photo Mode carousels use the same 1080x1920px (9:16) vertical frame and let viewers swipe through a set of images. Mixing aspect ratios across slides causes uneven cropping.
Profile Picture
Updated 2026Profile photos are uploaded around 720x720px (1:1) and shown in a small circle, so use a clear, high-contrast image that reads at thumbnail size.
