Resize an Image for an Instagram Post
Instagram uploads look best at 1080 px wide — square for feed posts, portrait for maximum screen space. Crop to the right ratio and resize so Instagram doesn't recompress or crop your photo awkwardly.
The requirement
- Square post
- 1080 × 1080 px (1:1)
- Portrait post
- 1080 × 1350 px (4:5)
- Landscape post
- 1080 × 566 px (1.91:1)
- Format
- JPG or PNG
These are typical published values and can change from year to year and from one portal to another. Always confirm the exact requirement in the official notification or upload portal before you submit — the official source takes precedence over anything here.
Step by step
- 1Pick your layout — square, portrait or landscape — and crop to that ratio.
- 2Resize the width to 1080 px (height follows the ratio).
- 3Save and upload to Instagram.
