Apple App Store: Screenshot Sizes and Guidelines

Basic Principles

When publishing an app on the Apple App Store, you need to provide app screenshots in different sizes. For example, if you want to publish an app made for iPhone, you need to supply screenshots for a 6.5″ device (e.g. iPhone 11 Pro Max) and a 5.5″ device (e.g. iPhone 7 Plus).

Many developers leave screenshots until they are ready to publish their app and then rush them, ending up with low quality images. However, screenshots are important and play a huge role in driving more downloads.

Apple provides guidelines on what screenshots should communicate, e.g. here, but in summary, a good set of screenshots should:

  • be visually appealing
  • include simple language that’s straight to the point
  • employ a common design language

Here’s a great example:

SoSweat’s screenshots looks great, text is easy to read and to the point, and all screenshots share a common design language

Apple App Store Screenshot Guidelines

Apple currently requires app developers to supply screenshots for a range of devices. Apps for iPhone need to include screenshots for 6.5″ devices (e.g. iPhone 11 Pro Max) and 5.5″ devices (e.g. iPhone 7 Plus). If the app also targets iPad, then you also need to supply screenshots for both iPad Pro 2nd Gen (12.9″) and 3rd Gen (also 12.9″).

The following tables summarize the accepted resolutions for each of those devices.

App developers can upload up to ten screenshots and three options app previews (videos) for each device. The following formats are acceptable:

Screenshots must be in the JPG or PNG format, and in the RGB color space. App previews must be in the M4V, MP4, or MOV format and can’t exceed 500 MB.
