# love.window.getPixelScale

Available since LÖVE 0.9.1
This function is not supported in earlier versions.

Gets the DPI scale factor associated with the window. In Mac OS X with the window in a retina screen and the `highdpi` window flag enabled this will be 2.0, otherwise it will be 1.0.

The scale factor is used to display graphics at a size the user is expecting, rather than the size of the pixels. On retina displays with the `highdpi` window flag enabled, the pixels in the window are 2x smaller than the scale of the normal content on the screen, so love.window.getPixelScale will return 2.

## Function
