What size should Instagram stories be?

Instagram Stories and Reels should be 1080×1920px (9:16 aspect ratio). This is a full vertical phone screen format. Our Story preset creates exactly this size.

Will my image be cropped when resizing for Instagram?

Yes — to fit the exact Instagram dimensions without distortion, we center-crop your image to the correct ratio. Choose the format that best matches your original photo's orientation to minimize cropping.

Instagram Image Resizer — Perfect Dimensions for Post, Story & Reel

Resize your photos to the perfect dimensions for Instagram — square posts (1080×1080), landscape posts (1080×566), portrait posts (1080×1350), and stories/reels (1080×1920). Instagram uses specific aspect ratios to display content — uploading the wrong size causes unwanted cropping. This tool auto-crops your image to the exact Instagram format you choose, all in your browser without any app or account.
