How to detect the pixel pitch of a display

I'm looking for a way to match the size of the scale shown on the display with the actual size.
Is there a way to detect the pixel pitch of the display?

Hi,

you mean for getting the physical size?

That's unfortunately not possible, no today system or browser provides these information.

That best thing that could be done is using the user-agent of a mobile-device and looking it up on a device-database that contains the physical screen size.

krpano is doing something similar for the MobileVR/Cardboard support, because for the correct VR display and lens-distortion knowing the correct physical screensize is necessary:
