1080 × 1920, 9:16. What matters more than the resolution is that TikTok’s interface covers a large share of the frame — the caption along the bottom left and the action buttons down the right.
How to use the tiktok video size
The covered area is bigger than on Instagram: roughly the bottom quarter and a strip down the right-hand side, and the caption expands when someone taps it. Anything you need read — subtitles especially — belongs in the upper-middle. Subtitles matter here more than on any other platform, because a large share of TikTok is watched with sound off and the platform’s own auto-captions land in the same crowded bottom area. Burning your own captions higher in the frame is the reliable fix.
