Free to start — no card needed

Getting Instagram ad sizes right keeps your creative crisp and uncropped across placements. The essentials: 1:1 (1080×1080) or 4:5 (1080×1350) for feed, and 9:16 (1080×1920) for stories and reels. This guide lists the dimensions and safe zones — and shows how Atelio generates every placement size from one concept so you never letterbox a landscape ad into a story again.

Why brands use Atelio for this

Feed

1:1 (1080×1080) or 4:5 (1080×1350) — 4:5 takes up more screen and tends to perform better.

Stories & reels

9:16 (1080×1920) full-screen vertical; keep text inside the safe zone away from edges.

Generate all at once

Produce feed, story and reel sizes from one concept so a single idea ships everywhere.
