Condom sizing starts with girth, not just length. A condom should roll on easily, stay in place, and feel secure without squeezing hard enough to hurt, numb sensation, or leave a deep ring.
If you came here looking for a condom size calculator, use the Condom Size Calculator first. It turns girth into a target nominal width and suggests close product matches from the live chart. You can also compare every option in the Condom Size Chart.
Once you have a width range: sanity-check it against the closest brand family before buying. Use the Durex condom size guide for common latex and Durex latex-free fits, the SKYN and LifeStyles condom size chart for non-latex or standard-width options, or the Trojan and Magnum size chart for roomier latex choices.

How to measure for condom sizing
Use a soft measuring tape, or wrap a string around the shaft and measure the string against a ruler.
- Measure while erect.
- Measure girth around the middle of the shaft. If the head is much wider, measure there too.
- Measure length from the base to the tip.
- Use girth to choose width first, then use length to avoid condoms that are obviously too short or too long.
Length matters, but girth usually decides whether a condom feels too tight, too loose, or just right.
Condom size guidelines by girth
A rough shortcut is to divide erect girth by about 2.25 to estimate a comfortable flat condom width in inches, then convert to millimeters. The calculator does this work for you.
- Under 4.8 inches girth: look at snugger condoms such as Atlas True Fit Snugger.
- Around 4.8 to 5.1 inches girth: standard-width options often work well; SKYN Elite is a strong non-latex starting point.
- Around 5.2 inches girth and up: consider roomier options such as Trojan Magnum Raw.
- Much thicker than standard: compare larger-width options such as Caliber XL against the full chart.
What a correctly sized condom should feel like
A good fit should feel secure but not punishing. It should not slide around, bunch badly, cut off circulation, or feel so tight that sensation disappears. If a condom keeps slipping, move narrower. If it feels painfully tight or hard to roll down, move wider.
If you are unsure, test two nearby widths instead of guessing from labels like regular, large, or XL. Brand labels are inconsistent; nominal width is the cleaner comparison.
