Best image size for Instagram posts and stories
If your Instagram images look cropped, blurry, or inconsistent, the problem is often the file dimensions. Using the right Instagram image size makes posting faster and reduces extra editing work.
Quick answer
The most common Instagram sizes are 1080 x 1080 for square posts, 1080 x 1350 for portrait posts, and 1080 x 1920 for stories. These sizes work well because they match how Instagram usually displays images on mobile devices.

Why image size matters on Instagram
Posting the wrong dimensions can lead to awkward crops, wasted space, or extra resizing before publishing. For creators, marketers, and store owners, that slows down publishing and makes content look less polished.
Using the right Instagram image size also helps when you prepare several posts at once. You can keep visuals more consistent across your feed, stories, and product promotions.

Best format for Instagram uploads
JPEG is usually the easiest format for social posting because it keeps file size lower. PNG can still be useful in some cases, but larger files can slow down posting and sharing.
