You can try \expanded{\definemeasure[SpineWidth][...]}
Yes, that works. I could have thought of that myself.
\definemeasure[SpineWidth][2mm + (0.09mm * 1.5 * 90)] doesn’t work:
You can use integers to multiply or divide a length, a float is only allowed before a length. e.g. 1.5\scratchdimen or 1.5\dimexpr ...\relax
In your case you have to use
\definemeasure[SpineWidth][2mm + (0.09mm * 3 * 90 / 2)]
or
\definemeasure[SpineWidth][2mm + (0.09mm * 135)]
Ah, the float/int usage was the missing link. Now I can document my calculated cover for wiki, CG journal, my book, DTK... Hraban
