Points, where 1 Point = 1/72 inch.
Why using points instead of just pixels?, it's convenient because you can
forget about resolution, for example one might want to show some text on
screen, maybe 20 pixels height would look nice for a big title, but that is so
because screen resolution is perhaps 96 pixels per inch, but what happen when
the text is printed on a 1200 dpi printer? it will probably do not stand out,
so without points one would need a way to specify pixel heights for several
resolutions. So a good property of points is that they are independent of
resolution.
