An In-App Purchase in App Store Connect has two image fields, and people mix them up:
| Field | Purpose | Shown on the App Store? | Size |
|---|---|---|---|
| App Review Screenshot | Shows App Review the item exists in your app | No | Any screenshot specification your app supports |
| Image (promotional image) | Promotes the purchase on your product page, or sets up win-back offers | Yes | Fixed 1024 × 1024 |

So when you search "in app purchase screenshot size" or "in app purchase review screenshot dimensions," first decide which image you mean. The sizes are completely different.
Apple's description of the App Review Screenshot:
"Any of the screenshot specifications" means your app's regular screenshot sizes. For an iPhone app, the required slot's 1206 × 2622 or 1179 × 2556 (iPhone with Dynamic Island, medium display) works. If you support iPad, the 13-inch 2064 × 2752 or 2048 × 2732 also works. The full list is in our App Store screenshot size guide.
The general screenshot rules apply too: .jpeg, .jpg or .png, and no alpha channel.
If the reviewer needs a test account, put it in Review Notes on the same page (up to 4,000 characters).
You need it only when you want to promote the In-App Purchase on your product page or set up win-back offers. Also, if you use offer codes for auto-renewable subscriptions, the promotional image appears on the App Store page when customers redeem codes on iOS 14 or later.
Apple's requirements:
The image represents the purchase in every country or region where your app is available. Design tips are in our promoted In-App Purchase image guide.
Uploading the 1024 × 1024 image as the review screenshot. 1024 × 1024 isn't an iPhone or iPad screenshot size. Use a screenshot size.
Polishing the review screenshot like marketing art. Apple says it's for review only. Spend that time on the promotional image and your product page screenshots.
Uploading a placeholder to delete later. You can update it but you can't remove it. Upload a clear one the first time.
The localized fields on the same page have these limits:
Changes to localized information go through review. The old text stays live until the new text is approved.
What is the in app purchase screenshot size, exactly? There's no separate size for the review screenshot. Use any screenshot size your app supports, such as 1206 × 2622 for iPhone. Only the promotional image is fixed at 1024 × 1024.
Do I need a review screenshot per language? On Apple's page the review screenshot is part of the general information, not the localizable fields. Upload one as the page asks.
Do I need the promotional image if I'm not promoting the item? Apple says it's required when you want to promote the item on your product page or set up win-back offers.
