🚨 Ecomm and catalog advertisers on Meta, you may want to check your ad previews today.

The transition from square to 4:5 vertical images is coming to catalog ads. You may have some weird crops if you were using overlays and images optimized for square viewing.

Per Meta’s design specifications for carousel ads:

The 4:5 aspect ratio is only available for Advantage+ catalog ads that are created using the carousel format and with product images from your catalog.

Expect 4:5 to be the new default soon and prep your designers accordingly.
