When submitting your awesome app to the iOS App Store you need to provide screenshots for all the iPhone/iPod/iPad screen sizes. In itunes connect they're labeled by the inch size of the screen, but this doesn't help you know which simulator to fire up. So, here's a handy table of all the portrait screen sizes:
- 3.5 inch (4s) 640×960
- 4 inch (5, 5s) 640×1136
- 4.7 inch (6) 750×1334
- 5.5 inch (6+) 1242×2208
It's also worth knowing that although you can update your app description after submitting the app, you can only update your screenshots with a full new app version. So make sure you get them right with your submission.
