The screen size map.
Yes, this is a map of popular screen sizes used with web browsers. It should provide you with an overview when planing for responsive web design. This map is work in progress. If you find anything missing or wrong: please ping us. If you like it: feel free to share it.

Units and values
Displays come in various resolutions, such as Retina, HD or 4K. This map uses an unit called device-independent-pixel (dp), which is not considering different screen resolutions. Instead dp is a unit used by designers and developers to set the sizes and values of layout elements for websites – no matter in which pixel density they will be rendered on a device.
We grouped screen sizes for the purpose of visualisation. They don't necessarily have to be seen as breakpoints in a responsive design.
