Creative formats

These are the numbers the network actually enforces on upload, read from the same catalogue the creative studio validates against.

Two rules worth knowing before you design
  • Headlines over 60 characters risk being cut off on mobile devices.
  • Brand logos should be 1:1, at least 120×120, with a transparent background — a solid one shows as a visible box on a publisher's page.
