Frequently asked questions

What's the best image size for Instagram?
1080×1080 for square posts. For portrait it's 1080×1350, and for stories/reels it's 1080×1920.
Why does Instagram blur my photos?
Usually because they're the wrong size and Instagram re-compresses them. Uploading at exactly 1080px wide keeps them sharp.
