A free, ad-free tool that turns your girth into a condom width in mm, using 178 condoms from 18 brands.
Who runs this site?
The publisher of Condom Size Calculator is Dimensa Health LLC, 3500 South Dupont Highway, Dover, DE 19901, United States. We don't sell condoms, earn no commission and run no ads. No brand pays for a spot in a table.
Where our figures come from
The manufacturer's own page or size chart is the source for all widths, lengths and wall thicknesses, and each row links there. The girth bands come from the Mister Size size table, named again under each chart.
The whole dataset is yours to reuse at no cost under CC BY 4.0, and you can download the CSV.
How the width is worked out
You measure your girth
The distance around the thickest part of your erect penis, in centimetres or inches.
We find your row in one size table
The condom brand Mister Size publishes a table that matches each girth range to a width in mm. We use that table for every brand, because a width in mm means the same on any box.
We list the condoms at that width
Every product within 1 mm of your width shows up, from any brand, each linked to the page its figures come from.
The table is a guide from one brand, not a medical test. Bodies and materials differ, so treat the answer as the width to try first. You can check every figure in the condom size chart, the CSV file or the Mister Size table itself.
Contact us and corrections
Spotted a width that its manufacturer has since changed? The quickest route is an email to contact@condom-size-calculator.com with the product name and a link to the page that shows the new width. Postal mail reaches us at Dimensa Health LLC, 3500 South Dupont Highway, Dover, DE 19901, United States. No figure changes until we've checked the report against the manufacturer's own page.
This site doesn't offer medical advice. See a doctor or a sexual health clinic about pain, a rash, or a condom breaking over and over even when the size fits.
