Quick answer: Durex fit starts with nominal width. Measure erect girth, divide by about 2.25, then compare the result with Durex widths. In the current Durex set we track, 52 mm is the closer fit, 54 mm is the standard middle, and 56 mm is the roomier Durex lane. If you want the interactive version, use the condom size calculator first, then confirm details in the Durex condom size chart.
Best path: measure girth, run the condom size calculator, compare Durex-only options in the Durex size guide, and use the full condom size chart if none of the Durex widths are close. For measuring help, keep the condom sizing guide and the girth-to-width formula guide open.
Durex condom size calculator shortcut
Use this table as a quick Durex-specific shortcut after you measure girth. The formula is simple: convert girth to millimeters, then divide by 2.25 to estimate a starting nominal width. Condom comfort still depends on shape, stretch, lubrication, and sensitivity, so treat the result as a first filter.
| If your calculated width is closest to… | Start with | Why |
|---|---|---|
| 52 mm | Durex Air Close Fit | Closer Durex fit if regular-width condoms feel loose or baggy |
| 54 mm | Durex Air Transparent or Durex Extra Sensitive Thin | Standard Durex lane for many average-width shoppers |
| 56 mm | Durex Avanti Bare Real Feel or Durex Performax Intense | Roomier Durex lane, including one non-latex option |
| Wider than 56 mm | Trojan and Magnum size chart or full condom chart | Durex may not be the best first brand family if you need more width |

Durex sizes at a glance
| Durex condom | Nominal width | Material | Best fit use |
|---|---|---|---|
| Durex Air Close Fit | 52 mm | Latex | Closer fit when standard condoms feel loose |

Which Durex size should you use?
If regular condoms feel loose, start with the 52 mm lane before jumping brands. Durex Air Close Fit is the cleanest Durex starting point in this narrower range.
If regular condoms usually fit and you want a thin-feel latex condom, the 54 mm lane is the practical middle. Compare Durex Air Transparent with Durex Extra Sensitive Thin if sensation is the main reason you are shopping Durex.
If 52-54 mm condoms feel tight, look at the 56 mm lane. Durex Avanti Bare Real Feel is useful if latex-free material matters, while Durex Performax Intense is more about a roomier latex fit with delay lubricant.
When Durex is not the best size match
If your calculated nominal width is well above 56 mm, do not force a Durex choice just because you know the brand. Use the Trojan and Magnum size chart for larger mainstream latex options, the SKYN and LifeStyles size chart for nearby non-latex and standard-width alternatives, or the non-latex condoms by size guide if material and width both matter.
Durex size questions
Does Durex have different condom sizes?
Yes. The Durex products we track here cluster around 52 mm, 54 mm, and 56 mm nominal width. That width difference is small on paper but noticeable in use.
Is there a Durex condom size calculator?
Use our condom size calculator as the calculator, then filter your result against the Durex widths on this page. Durex brand names alone do not tell you enough; nominal width is the useful comparison.
Are Durex condoms smaller than Trojan?
Some Durex options are narrower than the better-known Trojan and Magnum large-fit products. If you are comparing mainstream larger condoms, use the Trojan and Magnum size chart before buying.
What if Durex condoms feel too tight?
Move up by width first, then compare brands. If 56 mm Durex still feels tight, the next smart step is not another Durex guess. Use the calculator, then compare the full chart or the Trojan/Magnum size guide.
Bottom line
For most Durex shoppers, the decision is simple: 52 mm if regular condoms feel loose, 54 mm if regular condoms fit, and 56 mm if you need more room. Measure once, run the calculator, and then use the Durex chart before buying.
