How to get correct screenshot resolutions?

Hello,

Trying to upload an app to the store and got hit by guidelines.

According to the screenshots specifications for Iphone 11 the resolutions are:
1242 x 2688 pixels (portrait)
2688 x 1242 pixels (landscape)
Link to specifications: https://help.apple.com/app-store-connect/#/devd274dd925

Yet my Iphone 11, does 828 × 1792 resolution screenshots, so I hope you understand how this is confusing...

How are people getting their screenshots? Can't seem to find an option to change resolution in my phone.

Rather than target one screensize for the store, it can help to capture the largest, say via the Simulator, then re-size down accordingly.

If you insist on grabbing something singularly out of spec, you'll need to open the image, say in Preview on your mac, and resize there.

Note there are macOS applications in the store that can take one parent image, then batch-generate all the others as required by the store, thereby simplifying the process, etc.

I see, thank you.

That's a great "note" but that is it called? there are about 100 resizing apps....

But why do the devices themselves not produce the specified screenshot dimensions? boggle
