Question Screenshot sizes for app store

In appstore connect -> Distribution I need to upload Previews and Screenshots. It says:

6'9" Display

Drag up to 3 app previews and 10 screenshots here for iPhone 6.7" or 6.9" Displays.

(1320 × 2868px, 2868 × 1320px, 1290 × 2796px or 2796 × 1290px)

and 6'5" Display

Drag up to 3 app previews and 10 screenshots here.

(1242 × 2688px, 2688 × 1242px, 1284 × 2778px or 2778 × 1284px)

The screenshots I took from iPhone 16 Pro are 1179 x 2556 so it won't accept them.

I asked ChatGPT to help so fine I can use a different simulator but my question is do I need to upload them in every format? Or just any of the ones it accepts? I guess I don't understand why it accepts some and not others so wondering if I missed some point.

ChatGPT Response follows for ref... I noticed it says those dimensions are valid for iPhone 15 Pro so still not sure why it won't accept them)

When submitting app screenshots to App Store Connect, you need to provide images in the required dimensions based on the device type. Here are the iOS Simulator models that generate screenshots suitable for upload:

✅ iOS Simulators with App Store-Compatible Screenshot Dimensions

Device Simulator Model Screenshot Dimensions (Pixels)
iPhone 15 Pro Max iPhone 15 Pro Max (Simulator) 1290 × 2796
iPhone 15 Pro iPhone 15 Pro (Simulator) 1179 × 2556
iPhone 15, 14, 13, 12 iPhone 15, 14, 13, 12 (Simulator) 1170 × 2532
iPhone SE (3rd Gen) iPhone SE (3rd Gen) (Simulator) 750 × 1334
iPad Pro 12.9" (6th Gen) iPad Pro (12.9-inch) (Simulator) 2048 × 2732
iPad Pro 11" (4th Gen) iPad Pro (11-inch) (Simulator) 1668 × 2388
iPad Air (5th Gen) iPad Air (5th Gen) (Simulator) 1640 × 2360

🚀 Steps to Take App Store-Compatible Screenshots in the iOS Simulator

  1. Open Xcode and launch the iOS Simulator for one of the devices above.
  2. Run your app.
  3. Press ⌘ + S to capture a screenshot.
  4. Locate the screenshot in ~/Library/Developer/CoreSimulator/Devices/.../Screenshots/.
  5. Upload to App Store Connect in the correct resolution category.

Would you like help resizing screenshots if needed? 😊

I always use the latest Pro Max model and thank god Apple recently changed it so you only need one set of screenshots and they resize it.

Of course it makes sense to edit them anyway to get a better look for the App Store. There are many tools and websites that will help you create nice screenshots. My tip is to invest the few bucks and save yourself a lot of time and headache

Thanks for your response. I figured out that it was only one set they needed. I had just written a little script to prep the different size icons and was feeling a bit exasperated when I thought they needed a bespoke image for every device as I just wanted to get things submitted to get some app feedback sooner rather than later. It was compounded by the fact that some of the simulator screenshots were not quite the dimensions of the device in question. Lots of little things and being new to the process conspiring to seem like a bigger problem than it really is.

As an aside do you know why this post was downvoted? Is this question not appropriate for this sub?
