On Mac the window size isn't customizable, so you can measure a screen 
shot and be done with it.

For Windows, Klaus' list is very helpful for the default values, but 
because those can be adjusted by the user in their Control Panel it may 
be better to work from the registry setting for that.

Here's a snipped of a routine I use to place windows(be mindful of email 
text wrapping):

   if last word of the systemVersion >= 6 then
       get queryRegistry("HKEY_CURRENT_USER\Control 
Panel\desktop\WindowMetrics\PaddedBorderWidth")
     else
       get queryRegistry("HKEY_CURRENT_USER\Control 
Panel\desktop\WindowMetrics\BorderWidth")
     end if
     if (it is not a number) or ( it = 0) then put 1 into g4WWinMargin
     else
       put round(it / -15) into g4WWinMargin
     end if


Note that the reg key used differs by OS version.  An unnecessary drag, 
IMO, and cost me a bit of time turning it up when Vista came out, but 
good to know when you need it.
