11 cm around works out to about 3.5 cm (1.4 in) across.
This girth calls for a standard condom, roughly a 50 mm nominal (lay-flat) width. Fit is set by girth, not length.
What this size means
Slimmer than average, and well within the normal spread: 90% of men measure between about 9.9 and 13.5 cm around. Width, not length, decides condom fit, so check the fit box above before buying.
