Instagram square post 1080×1080
The workable 1:1 square post canvas. Instagram preserves original resolution between 320 and 1080px wide and ratios from 1.91:1 to 3:4; outside that it crops.

Framing advice
- 1080px is the widest the platform processes photos; below 320px it upscales to 320px.
- This spec always outputs a square. When you need a portrait image, choose the matching portrait canvas instead of relying on the platform’s crop.
- Preview the published result in the feed and on the profile grid so nothing important ends up at the edges.
The most common failure
Posting a 16:9 landscape straight into a square slot: the platform centre-crops and the sides are gone.
