Condom Size Guide

Measure once and this guide works out the nominal width and length to look for, plus the fit category and the material that suits you. Take both measurements at full erection — length from base to tip along the top, girth around the thickest point of the shaft.

The Condom Size Guide is only an estimate based on two measurements. Published nominal widths vary between manufacturers and between production runs, so treat the result as a starting point and try a size either side of it to find what stays in place and feels comfortable.

The guide is not medical advice and does not diagnose or treat any condition. If condoms repeatedly slip or break, or if fit is painful, consult a licensed healthcare provider.


Why does condom fit matter?


Too tight: increased breakage risk, reduced sensation, can contribute to ED. Too loose: slips off, loses effectiveness. A properly fitted condom is more reliable and more comfortable.

What's 'nominal width'?


The width of the condom when laid flat — the standard size spec manufacturers publish. A flat width of ~52 mm is 'standard'; snug is 45–49 mm, large 55–57 mm, XL 58+ mm.

How do I measure properly?


Take both measurements at full erection. Length: from the base (pressed gently against the pubic bone) to the tip along the top. Girth: wrap a flexible tape around the thickest part of the shaft — usually just below the head.

Latex allergy — what are my options?


Polyisoprene (closest feel to latex) or polyurethane are both effective latex-free options. Lambskin condoms don't protect against STIs — they have micro-pores.
