FAQ
Instagram image size: questions and answers
What is the best Instagram post size?
1080 × 1350 px (4:5 portrait) takes up the most room in the feed. 1080 × 1080 px (1:1 square) is the classic size. Both are one tap away here.
What size is an Instagram Story?
1080 × 1920 px, a tall 9:16 frame. The same size works for Reels covers, Facebook Stories and WhatsApp Status.
Why does Instagram crop or blur my photo?
Instagram crops photos that are wider or taller than it allows and recompresses large files. Resizing to exactly 1080 px wide in the right shape first means you choose the crop, not the app.
Is my photo uploaded to a server?
No. The image is resized inside your web browser on your own device, so 0 bytes are uploaded and nothing is stored. It even works offline once the page has loaded.
