Why 1080×1920
A 9:16 frame fills the whole phone screen. Horizontal videos play with large black bars above and below, which makes them look small in the For You feed. 1080×1920 is also what Instagram Reels and YouTube Shorts recommend, so one export works for all three.
Frame rate
TikTok accepts 23 to 60 fps. Export at the frame rate you filmed, usually 30 fps. Converting 24 fps footage to 60 fps does not make it smoother and makes the file bigger.
Leave room for the interface
TikTok puts the caption, sound name and buttons over the bottom and right side of the video. Keep text, faces and products in the middle of the frame.
