Snug fit finder
Find condoms that actually fit.
Two measurements, about two minutes, all in private. We'll work out your size and show you condoms chosen for it, with honest notes on each one.
How it works
No account, no email and nothing to send us.
Measure in private
Clear step-by-step pictures show you exactly what to measure. A tape measure, or a strip of paper and a ruler, is all you need.
See your size
We turn your girth into a condom width, the number on the pack that decides whether it stays put.
Compare, save and buy
Every product shows how it should fit you. Save your search, share it with a partner, and buy from the retailer.
Your numbers stay with you
Measurements are worked out in your browser and never sent anywhere. They're forgotten when you close the tab, unless you choose to save them.
Width matters most
Condoms that slip are almost always too wide, not too long. That's why we size you by girth first.
Easy to share
Send a link to a partner so you're both looking at the same shortlist. You choose whether it includes your measurements.
Questions
Why does width matter more than length?
Condoms are very stretchy lengthways, and most are longer than anyone needs, so the extra simply stays rolled at the base. Width is what stops a condom slipping off, so that's what we match.
Should I measure when erect?
Yes. Condoms are sized for erect measurements, so measuring when soft won't give you a useful answer.
What if I'm between two sizes?
Most people are. We show a range rather than one number, and label each product as a great fit, a snug fit or a bit roomy, so you can choose what feels right.
Is this medical advice?
No. It's a sizing guide. If you have pain, irritation or a latex allergy, a pharmacist or GP can help, and we mark latex-free options clearly.
