Instagram Image Size Guide 2026: Resize for Perfect Posts
Instagram Image Size Guide 2026
Getting the right Instagram image size is crucial. Upload an image that is too small and it looks blurry. Upload one that is the wrong aspect ratio and Instagram crops it, cutting off important parts of your photo. This guide covers every Instagram format with the exact dimensions you need.
Instagram Post Sizes
| Post Type | Aspect Ratio | Recommended Size (px) |
|---|---|---|
| Square post | 1:1 | 1080 x 1080 |
| Portrait post | 4:5 | 1080 x 1350 |
| Landscape post | 1.91:1 | 1080 x 566 |
Instagram displays posts at a maximum width of 1080 pixels. Uploading larger images does not improve quality — Instagram will compress them down. For the sharpest results, upload at exactly 1080px wide.
Instagram Story and Reel Sizes
| Format | Aspect Ratio | Recommended Size (px) |
|---|---|---|
| Story | 9:16 | 1080 x 1920 |
| Reel | 9:16 | 1080 x 1920 |
| Reel cover | 1:1 | 1080 x 1080 |
Stories and Reels fill the entire phone screen in vertical orientation. The 9:16 aspect ratio is non-negotiable — any other ratio will result in cropping or letterboxing.
Instagram Profile and Highlight Sizes
| Element | Recommended Size (px) |
|---|---|
| Profile photo | 320 x 320 |
| Highlight cover | 1080 x 1080 |
Profile photos appear as circles, so make sure your important content is centered and not in the corners.
How to Resize Images for Instagram
Using PicKit Resize Tool
The fastest way to resize images for Instagram is using PicKit resize tool:
- Open the resize tool

PicKit includes presets for all Instagram formats, so you never have to remember the exact pixel dimensions.
Crop for the Right Aspect Ratio
If your image is the wrong aspect ratio, you need to crop it before posting:
- Open PicKit crop tool
- Upload your image
- Select the aspect ratio (1:1 for square, 4:5 for portrait, 9:16 for stories)
- Position the crop area to keep the most important part
- Download the cropped image
Compress for Fast Upload
Instagram compresses uploaded images, but starting with an optimized file gives better results:
- Use PicKit compressor after resizing
- Target 85% quality for the best balance
- Keep file size under 1MB for fastest upload
Tips for Best Instagram Image Quality
- Upload at 1080px wide: This is Instagram display width. Larger files get compressed, smaller ones look blurry.
- Use JPEG format: Instagram works best with JPEG. Convert PNG or WebP files using the format converter.
- Keep file size reasonable: Under 1MB uploads retain the most quality after Instagram processing.
- Avoid screenshots: They compress poorly. Use original photos whenever possible.
- Check on mobile: Always preview how your post looks on a phone before publishing.
FAQ
What happens if I upload an image larger than 1080px to Instagram? Instagram automatically compresses images larger than 1080px wide down to 1080px. This compression can reduce quality. For the best results, resize to exactly 1080px wide before uploading using the resize tool.
Can I upload PNG to Instagram? Yes, but Instagram converts PNG to JPEG during upload, which can reduce quality. For best results, convert your PNG to JPEG first using the image converter, then upload the JPEG file.
Why does my Instagram story look blurry? Stories look blurry when the image is not 1080 x 1920 pixels (9:16 ratio). If your image is a different size, Instagram stretches or crops it. Always resize to exactly 1080 x 1920 before uploading stories using the resize tool.
