Resize images for Instagram — 1080×1080 and up
Instagram crops and compresses badly if you feed it the wrong dimensions. Prep up to 20 images at the correct size before you post.

How it works
Choose your target
For square feed posts use 1080×1080. For portrait posts use 1080×1350. For stories and reels use 1080×1920.
Download and post
Instagram re-compresses everything you upload, so starting at 1080 wide with quality 90 gives it the best source material.
Questions
What size should Instagram images be?
Square post: 1080×1080. Portrait post: 1080×1350 (4:5, takes the most screen space). Story and Reel: 1080×1920 (9:16). Profile picture: 320×320.
Why do my posts look blurry?
Usually because you uploaded a small image and Instagram upscaled it, or you uploaded something enormous and it over-compressed. Feeding it exactly 1080 wide solves both.
Will this crop my image?
No — it only scales. If your aspect ratio does not match Instagram's, decide on your crop in an editor first, then resize here.
Does Instagram strip quality on upload?
It re-encodes everything. Uploading a correctly-sized, high-quality JPEG minimises the damage.
Instagram dimensions, current
Instagram has changed these more than once. These are the sizes that are accepted without downscaling as of now.
| Case | Value | Why it matters |
|---|---|---|
| Square feed post | 1080 × 1080 | 1:1. Safe everywhere; no crop in the grid. |
| Portrait feed post | 1080 × 1350 | 4:5. Takes the most vertical space in the feed, which is why it performs best. |
| Landscape feed post | 1080 × 566 | 1.91:1. Occupies the least feed space — worst reach per post. |
| Story / Reel | 1080 × 1920 | 9:16. Keep text away from the top 250 px and bottom 340 px, which the UI covers. |
| Profile picture | 320 × 320 | Displayed as a circle; upload square or it gets cropped from the centre. |
| Carousel slide | 1080 × 1350 | All slides must share the same ratio, or Instagram reshapes them. |
Five mistakes that waste the most time
Uploading full-resolution camera files
A 6000 px JPEG gets re-compressed to 1080 wide by Instagram with a harsher encoder than yours. Pre-shrinking to exactly 1080 with quality 90 preserves far more detail.
Sharpening before upload
Instagram applies its own sharpening pass. Pre-sharpening produces halo artefacts. Do the opposite: upload slightly soft.
Mixing ratios in a carousel
One 1:1 slide and one 4:5 slide forces Instagram to crop or pad the mismatched one.
Placing text in Story safe zones
Text within 250 px of the top or 340 px of the bottom is hidden behind the UI.
Exporting at quality 100
Quality 100 JPEG is often 3× larger with no visible gain, and Instagram compresses it away anyway. Quality 90 is the practical ceiling.

More questions
Does Instagram compress every upload?
Yes, always. You cannot avoid it. You can only control the starting quality, which is the entire point of pre-sizing to 1080.
Should I use 1080 or 1440 wide?
1080. Instagram downscales to 1080 wide on the standard path. Uploading 1440 gives it more bytes to throw away.
Why do my Reels look soft?
Reels are usually 1080 × 1920. If you cropped a horizontal video and stretched it, you lose resolution. Export native vertical instead.
Are these sizes different for Instagram on Android?
No. The upload pipeline normalises the same way on both platforms.
