Snapchat ad size

1080 × 1920 full screen, 9:16. The interface takes roughly the top 8 percent and bottom 20 percent, the latter for the swipe-up call to action.

The format constraint people underestimate is time rather than pixels. Snapchat ads are skippable almost immediately, so the first frame has to carry the message on its own — treat it as a poster rather than as the opening of a story. Snapchat’s own guidance is to front-load the brand in the first two seconds. The 9:16 full-screen frame is the same canvas as a TikTok or an Instagram story, which makes cross-posting easy, but the safe areas differ enough that a design pushed to the very bottom on one will sit under the call to action on another.
