What matters
TikTok Video Cover dimensions at a glance
TikTok video covers at 1080×1920 fill the full screen in the feed but get cropped to roughly 3:4 in the profile grid. The key visual needs to survive both contexts.
A well-designed cover turns your profile grid from random frame grabs into a cohesive portfolio. It also helps videos get tapped from the grid.
Text or subjects at the top and bottom get cropped in grid view. Auto-selected frames look unprofessional and random.
