When you say the dialog is compacted, is it completely shrunk, or is it somewhat normal size with the text being too small?

Code:
//echo -a width $window(-1).w height $window(-1).h / dbuw $dbuw dbuh $dbuh


I'm curious what are the dbuw/dbuh values relative to the pixels width/height. I was under the impression that dbuw/dbuh were supposed to vary so that pixel-size divided by dbu-size would always be somewhere in the same ballpark.
