What works on TikTok.

Shoot and design for 9:16 — anything else gets bands.
Keep text away from the bottom and right edge, where the caption and buttons sit.
Turn a slide post into photo mode or a short video with a voiceover; both keep the order.
Write the caption to 2,200 if a tool posts for you.
