Six scales on one ruler, so a 10-foot booth is one quick tick instead of arithmetic.
This is the three-sided ruler draftsmen use. Each face carries two scales, so you pick the one where your booth size lands on a clean mark and draw every space the same width without measuring twice.
The scales are laser-etched into aluminum rather than printed, so they do not rub off in a bag full of markers.
