What is the Instagram profile photo size?
Instagram profile photos are stored at 320×320 pixels and displayed in a circle. Upload a square image at 320×320 or larger for the best quality.
Why does my Instagram profile picture look blurry?
Uploading an image smaller than 320×320 will cause Instagram to upscale it, making it blurry. Always use an image at least 320×320 pixels. Avoid heavy compression before uploading.
How do I make my profile picture fit without cropping?
Instagram crops profile photos into a circle from a square image. Make sure your face or logo is centered within the square so nothing important is cut off by the circular mask.
