Instagram accepts several formats, but the safest choices are 1080 x 1080 px for square posts, 1080 x 1350 px for portrait posts and 1080 x 1920 px for Stories and Reels. Resizing before upload gives you control over the crop.
Portrait posts use more vertical feed space than square posts, while Stories and Reels need a full vertical 9:16 image.
| Format | Size | Use it for |
|---|---|---|
| Square post | 1080 x 1080 px | Products, quotes, profile-style visuals |
| Portrait post | 1080 x 1350 px | Photos, food, fashion, tall compositions |
| Story / Reel | 1080 x 1920 px | Full-screen vertical content |
| Landscape post | 1080 x 566 px | Wide photos and previews |
Choose the Instagram format before you design text overlays or crop the image. A square post, portrait post and Story all use different visible space, so the same source photo can need three different crops.
After export, check the file size. Instagram will recompress uploads, but starting with a correctly sized image gives you a cleaner result and avoids unpredictable automatic cropping. If you are preparing multiple posts, resize every image to the same format first so the grid looks consistent.
Use the result from this page as the decision point for your next action. If the image has the wrong pixel dimensions, open Resize Image and export the exact width and height you need. If the dimensions are correct but the file is too large, use Compress Image or a fixed target page such as Compress Image to 100KB.
For print, verify the final file with the Image DPI Checker before ordering. For social uploads, use Instagram Image Size, Facebook Image Size or the full Social Media Image Size tool so the crop matches the platform before upload.
