How to Resize Images for Instagram (All Sizes)
Instagram supports multiple image formats and each has a specific recommended size. Using the wrong dimensions results in automatic cropping or blurring — this guide covers all the correct sizes.
Step-by-Step Instructions
1
Choose your format
Square post: 1080×1080px. Portrait post: 1080×1350px. Landscape post: 1080×566px. Story/Reel: 1080×1920px.
2
Upload and resize
Upload your image to the Instagram Resizer — the tool has all Instagram presets pre-loaded.
3
Choose Cover mode
Use Cover (crop-to-fill) mode for posts to ensure no white bars appear in the feed.
4
Export as JPEG at 90%
Save as JPEG at 90% quality for the best file size — Instagram will re-compress uploads anyway.

- Instagram crops the preview in the feed to a 4:5 ratio even for square posts — keep important content in the central 1080×1080 area.
- Use 1080×1350px (portrait) for the most feed real estate.
- Stories and Reels should always be 1080×1920px (9:16 ratio).
