Use 4:5 for feed posts
Portrait 4:5 (1080 × 1350 px) takes up the most room in the feed, so your post is more likely to be noticed.

About
Why resize photos for Instagram?
Instagram only accepts certain shapes. Feed posts can be anything from 1.91:1 landscape to 4:5 portrait, the profile grid has shown posts as 3:4 since 2025, and Stories and Reels are 9:16. A photo that doesn't match gets cropped, often cutting off heads, text or products. This resizer puts your whole photo into the right shape at 1080 px wide and fills the empty space with a blurred copy of the photo or a colour you choose.
Keep Story edges clear
Instagram shows the profile name at the top of a Story and the reply bar at the bottom. Keep important details away from the top and bottom 250 px.
Start with the original
Resize the original photo, not a screenshot or a copy downloaded from Instagram, for the sharpest result.

The photo is saved as a high-quality JPG at 1080 px wide, the width Instagram displays. Very small photos have to be enlarged and can look soft, so start with the largest version you have.
