These are all the graphic sizes used for the app and website.
Apple is very particular on graphics required for the apps. There are a few things that will cause Apple reject your app, including graphics requirements not being met precisely.
- You must submit the EXACT sizes listed below. If they are one pixel off they will not load.
- Images must be .PNG files with no transparency.
- The splashscreens should be similar in design to all other splash screens. All squares should be similar in design to other squares. Apple wants consistency in the theme of all of the graphics. Sponsored loading screens with different branding are okay.
- Images should not have a border.
- Graphics must be less than 4MB each.
