Hi list,
I'm trying to scale a text to the textwidth and textheight by keeping the aspect ratio, using different papersizes. When the dimensions get too big I get an "Arithmetic overflow". (I'm trying to do something similar to resizebox in LaTeX: http://tex.stackexchange.com/questions/55394/perfectly-scale-line-paragraph-...)
Minimal example: \setuppapersize[A4][A4] %% [A1][A1] \showframe \starttext \scale[factor=max,width=\textwidth,height=\textheight]{\framed[frame=on]{!}} \stoptext

Not sure where exactly, but likely you have reached a size calculation limit of TeX (seems like a box calculation since more text works fine). Start with the bigger font size if you want to enlarge the box that much: \setuppapersize[A4][A4] %% [A1][A1] \showframe \starttext \definedfont[Serif at 20pt] \scale[factor=max,width=\textwidth,height=\textheight]{\framed[frame=on]{!}} \stoptext Jano
