What size should an Instagram post be?

1080 × 1080 for square, 1080 × 1350 for portrait, and 1080 × 566 for landscape. Square is the safest default.

Why does Instagram make my photos blurry?

Instagram re-compresses anything larger than its display size. Uploading at exactly 1080px wide means less re-processing and a cleaner result.

Stories are 1080 × 1920 (9:16). The resizer includes that as a one-click preset.

Instagram displays square posts at 1080 × 1080 pixels. Uploading the right size stops Instagram from re-compressing and softening your image.
