A condom that is too wide slips. One that is too tight is uncomfortable and more likely to tear. Neither is a minor annoyance, and neither is solved by buying a different brand of standard condom — standard is a single width, and it does not fit everyone. This shelf holds the narrow end of the range: 45, 47 and 49 mm.
"Small" means nominal width, not length
Nominal width is the flat measurement across the condom when it lies unrolled — not its circumference, and not its length. It is the number that decides fit, and it is the number both brands here put on the box.
Standard condoms sit around 52 to 56 mm. Everything on this page is below that:
- 45 mm — the narrowest available here, from My Size Pro
- 47 mm — Mister Size XS, described by the brand as the smallest of its seven sizes
- 49 mm — Mister Size S, the step between narrow and standard
How to find your number
Measure the circumference of an erect penis at the thickest point, with a tailor's tape or a strip of paper you then hold against a ruler. Divide by two, then subtract about 10 per cent — condoms are made slightly narrower than the measurement so they grip. A circumference of 10.5 cm puts you near 47 mm; 11 cm, near 49.
If the result falls between two sizes, take the narrower one first. A condom that has to stretch a little stays put; one that does not have to, moves.
The two ranges, and how they differ
My Size Pro covers the widest span, from 45 mm upward, and sells in packs from 3 to 80. If you are at the very narrow end, this is where the 45 mm option lives — a pack of three is the cheapest test on the shelf.
Mister Size runs seven sizes and prices every pack size identically, whatever the width. Its own description of the 47 mm is worth repeating, because it reframes the question — a slimmer fit allows more flexibility, not less pleasure.
Buy three before you buy a hundred
The price ladder rewards commitment, heavily. Three Mister Size 47 cost about five times as much per condom as a hundred. The same applies at My Size, between 36 at 45 mm and 80.
That ladder is a good reason to buy the small pack first and the large pack second, not the other way round.
Common questions
Is a smaller condom weaker?
No. Width and wall thickness are separate specifications. A 47 mm condom is made to the same standard as a 56 mm one; it is simply cut narrower.
What if the length is wrong too?
Length matters far less. Condoms are made longer than almost anyone needs and are not meant to unroll completely — leaving some rolled at the base is normal and does not affect how it works.
I am between sizes. Which way?
Narrower. Grip is what keeps it on, and a condom that stretches slightly is doing its job. If it feels constricting rather than snug, move up one step.
Where do the other sizes live?
The full sized range covers 45 to 72 mm, and the wide end is the mirror of this page. For everything else, the main condom shelf is the place to start.
