I've had yet another look at screen font sizes on all platforms. As far
as I can tell the current behavior (in wbeta, probably not changed since
vbeta) is the best I can do at this time.
I've run win, win64, linux, linux64, and mac with the same screen
switched between them at 1280*1024 (LCD 19 real inches diagonal).
Here are the isigraph pixel heights for each point size on each
platform:
09 10 11 12 13 14 15 - point size
15 16 17 18 19 22 23 - win jwdw
14 15 16 18 20 21 23 - win jwdp (java 1.4)
14 15 16 18 20 21 23 - win64 jwdp (java 1.5)
14 15 17 19 21 22 23 - linux (java 1.4)
14 15 17 19 21 22 23 - linux64 (java 1.5)
12 13 14 16 17 18 20 - mac (java 1.4)
Comparisons with 45 lines on windows with notepad are exact at 12pt and
vary a little bit over the range.
At least in my test environment the linux results look OK. Comparing
with various linux text editors show quite a range in ideas of 12pt
though generally they are a bit larger than J.
The mac results are a bit small. But compared to other text apps on the
Mac they tend to be about right or even a bit large.
The screen rendered size is somewhat arbitrary and is stated to not be
exact. Everyone has there own ideas. In general Mac favors small,
Windows medium, and Linux large.
Examples and insight welcome. Note that comparisons with other than
1280*1024 on a roughly similar size screen introduce too many variables
to be usefull in doing any tweaking.

Subject: [Jbeta] Font sizes for Linux
I had a look at Linux with beta v and it
seems like it has the same font size problem
that is now fixed for Mac.
See the screenshot, which compares fonts in
J session, a font sampler and Mozilla, etc. browsers.

If the same phenomenon is visible on other systems
(that J fonts at size 13 look like 10pt in a browser),
then its the same problem as was fixed for Mac.
On Windows, the fonts in Java are OK.

...
* Mac fonts are smaller than Windows fonts, to be exact
The ratio reflects 96/72 DPI between Windows and Mac
As a result, fonts are disproportional to geometry
as shown in Plot demo. Grid uses some magic so
that fonts fit, but that may be non-standard ...
