Why vertical ads need a safe zone
A vertical ad fills the phone screen, and the platform draws its own interface on top of it: the account name, the caption, the call-to-action button, the like and share rail. Anything of yours underneath is hidden or unreadable, and the parts most often lost are exactly the ones you paid to show, the headline, the offer and the logo. Designing inside a safe area is the cheap fix. It costs nothing at the design stage and a lot to discover after the campaign is live.
