Instagram Feed (square) Ad Size: 1080×1080 px
Aspect ratio 1:1 · 1080×1080 pixels · JPG, PNG, MP4, MOV
The 1080×1080 square is Instagram's baseline feed asset — it renders cleanly on every device, in every grid preview, and gets used as the fallback for placements that don't have a native crop.
Why this size matters
1:1 is still the safest single-asset shape on Meta because it never gets letterboxed and previews correctly in the grid. It's not the highest-impression aspect (4:5 wins that on mobile feed) but it's the one you should ship first if you can only ship one.

Design tips that actually move the needle
- 01Export at exactly 1080×1080 — Instagram compresses harder when it has to downscale.
- 02Keep critical elements 60px inside every edge; the grid preview lightly crops.
- 03For product shots, place the SKU on-center — off-center compositions read as "stock" in the algorithm's preview.
- 04sRGB color profile, not Adobe RGB — Adobe RGB shifts colors in the mobile app.
- 05PNG only if you need transparency behind a logo; JPG at quality 85 is smaller and identical to the eye.
Common disapproval triggers
- — More than 20% text coverage in the image (soft-limited, not rejected — but reach drops).
- — Personal attribute callouts ("Are you overweight?") — instant rejection.
- — Before/after imagery on health/beauty products — restricted category.
People also ask
Is 1:1 still the best Instagram size in 2026?+
It's the safest single-asset shape but not the highest-performing. 4:5 (1080×1350) captures ~25% more vertical mobile feed real estate, so if you can ship two aspect ratios, ship 4:5 + 9:16.
What's the file size limit?+
30 MB for images, 4 GB for video (feed video max 60s, though anything over 15s completes at under 20%).
Do I need PNG or JPG?+
JPG at quality 85 is functionally identical and ~4× smaller. Use PNG only when you need real transparency (which the feed will flatten to white anyway).
What is 1:1 in pixels?+
For Instagram Feed (square), a 1:1 aspect ratio is 1080×1080 pixels. Any resolution with the same ratio works, but 1080×1080 px is the recommended native size and avoids upscaling.
Is 1080×1080 the right size for Instagram Feed (square)?+
Yes — 1080×1080 px (1:1) is the recommended Instagram Feed (square) ad size. Accepted formats: JPG, PNG, MP4, MOV. Maximum file size: 30 MB.
