How it works

The instagram story tool outputs images at exactly 1080×1920 pixels, matching the platform's current published guideline. Uploading an image at this precise size means the platform doesn't need to auto-crop or auto-scale it, so nothing important gets cut off and the result looks the same as what you designed. If your source photo has a different aspect ratio, the tool fits and centers it to 1080×1920 rather than stretching it, keeping proportions natural.

Tips for best results

Use a high-resolution source photo — platforms will crop or scale it, and a low-res start looks worse after upload.
Preview how the image looks on both mobile and desktop before publishing, since crops can differ.
Keep important content like faces or text away from the very edges in case the platform crops slightly differently.
Re-check platform size guidelines occasionally — social apps update recommended dimensions from time to time.

Frequently asked questions

What is the correct Instagram Story size?

Instagram Stories and Reels use a 9:16 vertical format. Our tool outputs the standard 1080x1920 px dimensions.

Will my horizontal photo work for Stories?

Our tool fits your image to the vertical format. Horizontal photos will have empty space on the sides or be cropped depending on the setting.

Can I add text or stickers after resizing?

Yes. Resize using our tool, then upload to Instagram where you can add text, stickers and other elements.

What format should Instagram Stories be in?

JPG for photos. PNG is also accepted by Instagram.

Can I use the same image for Stories and posts?

The dimensions are different. Use our Instagram Post tool for feed posts and this tool for Stories.

Will my photo be cropped automatically when I upload it to the platform?

Using the exact recommended size reduces the chance of an automatic crop, but always preview before posting.

Can I use this size for a different platform too?

Sizes are platform-specific, so check the exact requirement for each platform rather than reusing one size everywhere.

Do I need special software to prepare this size?

No, this tool runs entirely in your browser, so no software installation is needed.
