13,072
According to this blog post : ( from 2012 )
-
window.devicePixelRatio
is mostly trustworthy on most browsers. - On iOS devices, multiply
devicePixelRatio
byscreen.width
to get the physical pixel count. - On Android and Windows Phone devices, divide
screen.width
bydevicePixelRatio
to get the dips count.
2017 UPDATE:
This property returns the ratio of the resolution in physical pixels to the resolution in CSS pixels for the current display device. This value could also be interpreted as the ratio of pixel sizes: the size of one CSS pixel to the size of one physical pixel.
Desktop browsers support:
Chrome Edge Firefox Internet Explorer Opera Safari 49 (Yes) 49 11 41 9.1
Mobile Browsers:
Android Edge Firefox IE Mobile Opera Safari Mobile 4.4 (Yes) ? ? all 9.3

I have been looking around the web to find what browser support there is for

, without much luck.Does anyone know what browers/devices support this?

Huangism over 10 yearsif you need to support the newer iOS or androids, then this should work. Logically I would say any device with a pixel ratio that is greater than 1 should support this, but who knows... what do you need to do? Perhaps there are other ways to solving your problem

Jules almost 7 yearsNote: "On iOS devices, multiply devicePixelRatio by screen.width to get the physical pixel count" is no longer true - it gives an incorrect result on iPhone 6+, 6s+ & 7+ due to downsampling.
