Best Image Size for Instagram (2026 Guide) | Bsbshs
Open the tool →Instagram crops and compresses photos that aren't the right size, hurting quality. Resize to the correct dimensions first and your posts look crisp. Here are the sizes and how to hit them.
Instagram image sizes
- Square post — 1080 × 1080 pixels (1:1).
- Portrait post — 1080 × 1350 pixels (4:5), the tallest feed post allowed and great for reach.
- Landscape post — 1080 × 566 pixels (1.91:1).
- Stories and Reels — 1080 × 1920 pixels (9:16).
How to resize for Instagram
- Open the Resize tool and add your photo.
- Set the pixel dimensions for the format you want (e.g., 1080×1350).
- Crop first if the aspect ratio doesn't match, to avoid awkward cropping by Instagram.
- Download and upload.
Keep it sharp
Resize down to 1080 wide rather than letting Instagram shrink a huge file — you control the quality that way. Export as JPG at high quality for the best look after Instagram's own compression.
Do it privately
A browser resizer works on your device, so your photos aren't uploaded before you post.
