What kind of computer do you have? Browser probably just asks the OS
which likely has a good idea.

I've got a random Dell box here connected to a random LG monitor by a
traditional 15 pin (?) VGA cable, but Centos knows roughly how big the
screen is:

$ xdpyinfo | grep -A2 ^screen
screen #0:
  dimensions:    1920x1080 pixels (508x285 millimeters)
  resolution:    96x96 dots per inch
$ xrandr |head -n2
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
VGA1 connected 1920x1080+0+0 (normal left inverted right x axis y axis)
480mm x 270mm
$ 

In cases like this, xrandr is likely to have the more accurate value
and xdpyinfo has a size which assumes 96x96 dots per inch unless
configured otherwise. Lacking a ruler at hand, I can't tell if the
screen is 480 or 508 mm across, both are in the right ballpark. But in
previous cases where I have measured, xrandr was within 5mm.

And of course, on an all-in-one device like a phone or a laptop, the
system having an accurate notion of the screen size is less remarkable.
