TikTok Video Size & Aspect Ratio
TikTok is a 9:16 app. 1080×1920 is the export that fills the screen. Other ratios play, but they show bars or get cropped in the feed.

Export notes
Film or recrop 9:16. Stretching a 16:9 clip makes faces look wrong and still leaves bars.
Username, caption, and buttons sit on the right and bottom. Leave a quiet margin there.
Covers are the first frame or a chosen still — same 9:16 canvas.
