Why test your site on Apple iPad Air 4?

Two orientations to validate

On Apple iPad Air 4, your visitors constantly switch from portrait to landscape. Both orientations correspond to two different breakpoints, and the second is almost always the least tested.

2x density

With a density of 2x, Apple iPad Air 4 provides a useful benchmark to ensure your images remain sharp without serving unnecessarily large files.

4G connection

This model is representative of 4G usage. Testing on it ensures your page remains usable when images and fonts load slowly.

CSS viewport resolution of Apple iPad Air 4

This resolution is what your stylesheet actually manipulates. It determines the applied breakpoint, the number of displayed columns, and the size of your images.

  • 820 pixels in width
  • 1180 pixels in height

The height remains indicative: Safari, Chrome, and other mobile browsers reduce the visible area with their address bar, which folds on scroll.

Be cautious when analyzing your statistics: some tools only report the manufacturer resolution, never the CSS viewport presented here.
