Gord -
You'll note that I wrote "Create the workbook exactly the way you want
it".
You're right - pixels are almost impossible to work with. Graphics have
their own pixels per inch setting. Monitors have a set maximum number of
pixels per inch, but of course you can set the resolution to display a
different # of pixels per inch. In addition, while Macs equate points
and pixels per inch (i.e., 72 pixels/points per inch), Windows does an
automatic magnification (on almost everything *except* graphics) to
display 96 pixels per inch (points don't change). So a 12 point font
*generally* displays 16 pixels high. Because of that, web browsers,
(which may have a pixels per inch setting of their own), in order to
print, guess which platform/combination they're running on, and scale a
printout accordingly (though not always correctly).
I've found that, most of the time, when people mention "pixels" with
regard to column width, they mean "points", or rather something like
points that will stay relatively constant. So I assume that the OP
wanted the width of the column to be either 64 points or 64*(4/3) = 85.3
points.
Of course, Excel doesn't measure column width in points (except, sort
of, in Mac XL 2004). <g>
Instead, it sets it in character *widths* (using the "0" for
proportional fonts), so for my default of Verdana 10, the default 10
characters corresponds to 1.04" or 74.88 points. If I instead set my
default font to Courier New 12, the default 10 character widths is also
1.04", since the character widths are the same. OTOH, if I set the
default font to Verdana 12, the default width becomes 1.18" or 84.96
points. Again, this reflects the character *widths*, not heights, since
1.04" * 12/10 = 1.248", not 1.18"
In XL04, you *can* set the column widths directly in inches or
centimeters (since it assumes that the screen is at 72 ppi, and fonts
don't get scaled as in Windows). So you can set the column width
directly to 64/72 inches, or 0.89". The number of width units will
obviously vary with the font size.
