Does *anybody* here know what the hell the width of each character in a
Courier 10pt typeface is?! (Apparently it isn't 10pt.)

Thanks for the tips, guys.
Well, by a series of experiments, I have discovered that the neither the
character width or character hight of Courier 10pt is actually 10pt. The
distance from the baseline to the capline is more like 5.5pt or
something, and the distance between characters appears to be exactly 6pt...

Yes, the "pt" in fonts is a rather arbitrary measurement. I guess in
traditional typesetting it would refer to the height of the metal
"block" from which the letters were cut, so even there it would be only
indirectly related to the actual glyph dimensions.

Well, the glyph will be smaller than the metal block to allow some
whitespace around the glyph. But you'd think 10pt would be either the
width or the hieght of the block... Apparently it is neither.

Your point being...?
Last time I checked, PostScript measures everything in points.

"In metal type, the point size (and hence the em) is measured as the
height of the metal body from which the letter rises."
"In digital type, the relationship of the height of particular letters to
the em is arbitrarily set by the typeface designer. However, as a very
rough guideline, an 'average' font might have a cap height of 70% of the
em, and an x-height of 48% of the em."

With the "point size" corresponding to the em. In a 10pt font, one em
equals 10 points. The actual height of most letters will be smaller.

I knew that. ;-)

In other words, given a 10pt font, there is no way to determine how tall
or wide any of the letters are. (E.g., they could be 10pt, 1pt,
1000pt...) This is very helpful. :-/

Still doesn't help me figure out how wide the letters of Courier 10pt
are. (Being a monospace font, all the letters should be the same width...)
As I say, it appears to be exactly 6pt. But I have no idea why...

The size of a font refers to its height, not its width.
(And the "height" is that between two baselines in the font. The font
graphics themselves can go over those lines.)

I had a vague recollection this might be the case.

That at least makes some kind of sense...
