App Store Screenshot Rejected for Wrong Size: How to Fix It

The most common cause is simple: the screenshot does not match an accepted App Store slot. A file that is close, such as a resized canvas that is a few pixels off, still fails because the validation is based on exact dimensions.

Apple's current iPhone slots include sizes like 1320 x 2868, 1290 x 2796, and 1260 x 2736 for the 6.9-inch display class in portrait. If your app runs on iPad, Apple's 13-inch iPad slot accepts 2064 x 2752 or 2048 x 2732 in portrait. Landscape uses the same dimensions swapped.

A portrait screenshot and a landscape screenshot can use the same numbers in the opposite order, but they are not the same upload. For example, 1320 x 2868 is portrait, while 2868 x 1320 is landscape.

If your app is portrait-first, do not export the landscape version by accident. If your app is landscape-first, upload the landscape dimensions to the landscape slot and keep the full screenshot set consistent.

A raw screenshot from Simulator, Xcode, or a physical device can be useful as source material, but it is not automatically the right App Store Connect upload size. Device hardware pixels, display classes, status bars, and store upload slots do not always line up in the way you expect.

Use raw screenshots as the app UI inside the design, then export the final store screenshot from a canvas that matches the accepted slot. This keeps headlines, frames, backgrounds, and UI crops under control.

An iPhone screenshot cannot be uploaded into an iPad slot just because the aspect ratio feels similar. App Store Connect validates the device family as well as the exact pixel size.

If your app supports iPad, create a real iPad screenshot set instead of stretching the iPhone set. The 13-inch iPad slot is required for apps that run on iPad, and it uses different dimensions from iPhone slots.

Small export changes cause big delays. Cropping a few pixels from the top, exporting from a scaled artboard, compressing through another tool, or resizing a finished PNG can leave you with a file that looks correct but no longer matches Apple's accepted dimensions.

Avoid last-step resizing when possible. Recreate the screenshot on the correct canvas and export the final file once, so the dimensions are intentional instead of patched after the design is done.

First, check the image dimensions. Use the ScreenKit App Store Screenshot Size Checker or your operating system's image info panel to read the exact width and height.

Second, compare those dimensions with the accepted App Store screenshot sizes. Third, pick the right iPhone or iPad slot for the upload you are trying to fill.

Fourth, recreate or export the screenshot at the exact size instead of stretching a rejected file. Fifth, upload one test screenshot in App Store Connect before finishing the full set, so you catch size problems before repeating them across every image.
