I'm typing this on a laptop with an external display connected, in

different characteristics. What is the pixel size for this window?

On most Windows computers, the answer will be 96 dpi: the value is
controlled by a setting in Display Properties->Settings->Advanced, and
very few people actually change it.

The setting has little to do with physical reality. I've
just measured, and on the plain-vanilla monitor I'm using right
this minute, the resolutions are 76.2+ and 71.4+ dpi, horizontally
and vertically (30 dots/cm and 28.1+ dots/cm). Windows calls it
"96 dpi" -- high by one-third -- and ignores orientation.

I tried your method, a little bit rougher, but still only 0.6% error, on my
monitor.
