What TikTok says about covers
A 9x16 aspect ratio at 1080×1920 for the best results, with important elements kept away from the edges.
TikTok’s Creator Academy article on video covers says to use a 9x16 aspect ratio and a 1080×1920 pixel resolution for the best results. It also tells creators to work within the safety zone, the area of the frame that is not covered by For You feed elements such as buttons, the creator’s name and the caption, and suggests a simple rule: avoid placing elements around the edges of the frame.
