App Store Connect rejects screenshot upload: “incorrect size” (subscription purchase flow) — tried all documented sizes

Hello Apple Developer Forums,

I’m preparing to submit an app update that includes an in-app subscription. As part of the submission, I need to provide screenshots showing where the user initiates and completes the subscription purchase flow.

The issue is that App Store Connect keeps rejecting my screenshot upload with an “incorrect size” (or size invalid) error. I have already tried exporting the screenshot in all sizes and resolutions described in Apple’s documentation, but none of them are being accepted so far.

Could you please advise:

What exact pixel dimensions / format requirements App Store Connect currently enforces for these screenshots (including file type and color profile, if relevant)?

Whether there are any known issues or common causes for this error (e.g., metadata, alpha channel, scaling, or export settings)?

Any recommended workflow/tools to generate a compliant screenshot that reliably uploads?

Thank you in advance for your help.

Hello everyone,

Just a quick update in case it helps others: I was able to successfully upload the review screenshot after resizing it to 640 × 920 px. After using that exact resolution, App Store Connect accepted the image without the “incorrect size” error.

Thank you to everyone who shared suggestions and guidance.

  • iPhone 6.5" 1242 × 2688px, 2688 × 1242px, 1284 × 2778px or 2778 × 1284px
  • iPad 3" 2064 × 2752px, 2752 × 2064px, 2048 × 2732px or 2732 × 2048px
  • macOS 1440 x 900px

Welcome to the forums.

So just select a simulator in Xcode for iPhone and iPad (e.g., iPhone 16 Plus 6.7" and iPad Air 13") and run the app on them.

The screenshots generated by the simulator (cmd-S) will provide the right sized images.

Note that you have to provide only one size for iPhone and one size for iPad.
