How it compares
This girth calls for a large / XL condom, roughly a 57 mm nominal (lay-flat) width. Fit is set by girth, not length.
How this is measured
Girth is the circumference around the thickest part of the erect shaft, measured with a flexible tape or a strip of paper. It is unaffected by the bone-pressed convention that applies to length.
