Safe zones

TikTok’s UI overlays a lot of the frame: username and caption bottom-left, engagement icons (like, comment, share) down the right edge, and navigation at top and very bottom. On a 1080 × 1920 canvas, keep critical text and logos roughly:

  • 130 px clear at the top
  • 480–500 px clear at the bottom (caption + CTA + nav stack up)
  • 140 px clear on the right edge
  • 60 px clear on the left edge

These margins are approximate and shift with caption length and device — preview your layout with the image crop preview safe-zone overlay using your own margins.

Spark Ads

Spark Ads boost organic posts (yours or, with authorisation, a creator’s) instead of uploading standalone creative. Specs follow the organic post; engagement accrues to the original post.
