Understanding App Store Screenshot Requirements

When submitting an app to the Apple App Store, developers are required to provide screenshots for various device sizes. This ensures users see an accurate representation of the app on their specific device. App Store Connect will reject images that do not exactly match their strictly required pixel dimensions.

Key Required Dimensions

While Apple periodically updates its display requirements, standard mandatory dimensions typically include:

  • 6.7-inch Display: 1290 x 2796 pixels (Portrait) or 2796 x 1290 pixels (Landscape)
  • 6.5-inch Display: 1284 x 2778 pixels or 1242 x 2688 pixels (Portrait)
  • 5.5-inch Display: 1242 x 2208 pixels (Mandatory fallback for all iPhone apps)
  • 12.9-inch iPad Pro: 2048 x 2732 pixels (Mandatory for iPad apps)

Cover vs. Contain Modes

When adapting an app screenshot from one aspect ratio to another, developers have two primary scaling choices:

  • Cover: The image is scaled proportionally to fill the exact dimensions of the target screen. If the aspect ratios do not perfectly match, parts of the original image will be cropped out (usually at the top and bottom, or sides). This method is best when the difference in aspect ratio is minimal and no critical UI elements are near the edges.
  • Contain: The entire original image is scaled down proportionally until it completely fits inside the target dimensions. Because it does not crop the original image, this mode leaves empty space (letterboxing or pillarboxing). You can fill this empty space using a complementary background color to make the padding look intentional and cohesive with your app's branding.
