I have a pair of men's jeans. If I lay them flat, while buttoned, and measure the width of the cloth with a cloth measure, I get 16.5", so roughly a 33" circumference. They're a 32"x34" size pair, … so that's basically spot on.

Note that, at least AIUI, the measurement printed on the pair is the wearer's waist measurement, so we thus expect the measured circumference of the top of the jeans to be slightly wider, since men's jeans are not intended to sit at the waist.

The outer measurement will also be larger than the inner. If your waist measures precisely 32", a 32" outer-measurement waistband (sans some stretch) will be too snug.

While I don't disagree, the fabric is a few millimeters thick. I think there's more error in my measurement with a cloth measure with them laid on the bed than the inner vs. outer diameter.
