Measure Girth • Read Size Bands • Compare Nominal Width
Use the Condom Girth Chart to record erect penis circumference, convert your measurement between inches, centimetres and millimetres, and compare it with practical condom nominal-width ranges. Girth is a body circumference while nominal width is a flat product measurement, so this guide keeps the two clearly separate.
Look up your girth band, compare a package width, convert measurement units or average repeated circumference readings.
Enter circumference around the fullest part while erect and get the matching girth band plus a practical nominal-width comparison range.
Full circumference around the fullest part while erect.
Enter your girth and a manufacturer's nominal width to compare the product with your girth chart band.
Use the manufacturer's stated flat-width figure.
Convert girth between inches, centimetres and millimetres and immediately see the matching chart range.
Average up to three repeated readings and use the result to select the most relevant girth chart row.
A condom girth chart helps turn a body circumference measurement into a more useful product-comparison range. Start by measuring the erect shaft around its fullest part. The chart then places that circumference into a practical band and shows a nearby condom nominal-width range that may be worth comparing.
The chart does not claim that every person with the same girth needs the same product. Condom brands use different shapes, materials, stretch characteristics and technical dimensions. Treat the width range as a starting point, then verify the exact product.
| Penis Girth | Approx. Inches | Starting Nominal Width | Comparison Band |
|---|---|---|---|
| Under 100 mm | Under 3.94 in | 45–49 mm | Narrower comparison |
| 100–109 mm | 3.94–4.29 in | 49–52 mm | Close comparison |
| 110–119 mm | 4.33–4.69 in | 52–54 mm | Close / regular comparison |
| 120–129 mm | 4.72–5.08 in | 54–57 mm | Mid-range comparison |
| 130–139 mm | 5.12–5.47 in | 57–60 mm | Wider comparison |
| 140–149 mm | 5.51–5.87 in | 60–64 mm | Wide comparison |
| 150 mm+ | 5.91 in+ | 64–69 mm+ | Extra-wide comparison |
Measure while fully erect. Wrap a flexible measuring tape around the fullest part of the shaft. Keep the tape snug enough to touch the skin without leaving a gap, but do not pull it so tightly that it compresses the tissue. Record the number and the measurement unit immediately.
If a flexible tape is unavailable, use non-stretch string or a narrow paper strip. Mark where the ends meet, lay the material flat against a ruler and record the result. Avoid elastic cord because stretching changes the reading.
Girth and nominal width are different measurements. Penis girth describes the full circumference around the body. Condom nominal width describes the product width when it is laid flat and is normally stated in millimetres. This difference explains why a 54 mm nominal-width condom is not meant for a 54 mm body circumference.
Use the chart to compare these measurements appropriately rather than treating them as the same number.
Penis circumference may be measured in inches or centimetres, while condom width is often printed in millimetres. Converting your girth to millimetres makes chart lookup and product comparison easier.
| Inches | Centimetres | Millimetres | Use |
|---|---|---|---|
| 4.0 in | 10.16 cm | 101.6 mm | Close-width comparison |
| 4.5 in | 11.43 cm | 114.3 mm | Close / regular comparison |
| 5.0 in | 12.70 cm | 127.0 mm | Mid-range comparison |
| 5.5 in | 13.97 cm | 139.7 mm | Wider comparison |
| 6.0 in | 15.24 cm | 152.4 mm | Extra-wide comparison |
This figure uses the same measurement visual style as the first page and shows which measurement belongs to the body and which belongs to the condom.
Measure around the fullest part while erect. The tape wraps completely around the shaft.
Convert inches or centimetres into millimetres when you want an easier comparison with product dimensions.
Compare the manufacturer's flat-width figure in millimetres. It is not the same as body girth.
Find your measured girth in the first column and then read across to the nominal-width comparison band. If your measurement falls near the edge between two rows, compare nearby products rather than assuming only one width can work. Small differences in product contour and elasticity can change how similar nominal widths feel.
If you already use a condom that fits well, note its nominal width. That number can be a useful technical reference when comparing another model or brand.
No single chart can predict the exact feel of every condom. Products differ in nominal width, usable length, shape, thickness, elasticity, material and lubrication. Two models with the same listed width can therefore feel different.
Use the chart to narrow the search, then check the manufacturer's current product page or packet. Correct application, comfort and security are more important than forcing a product into a category simply because its width sits inside a chart band.
Girth mainly helps organise width comparison, while length helps you evaluate whether the condom has enough usable length to unroll correctly. A product may be long enough but feel too tight or too loose around the shaft, or it may have a suitable width while differing in length or contour.
When a manufacturer publishes both measurements, compare both. Do not use penis length alone to select the girth chart row.
Latex is common, but latex-free condoms are also available. Material influences stretch and feel, so a familiar nominal-width number may not feel identical when you switch material, brand or shape. Check the packet if you have a latex allergy or sensitivity.
If a width looks appropriate on the chart but repeatedly slips or feels painfully tight, compare a nearby width or a different model rather than assuming the body measurement must be wrong.
Correct sizing does not replace correct use. Use a new condom each time, check the expiry date and packet, and follow the instructions supplied with the exact product. For latex condoms, avoid oil-based lubricants because they can weaken latex.
External-condom guidance also advises pinching air from the tip, unrolling the condom fully and holding the base during withdrawal. Do not use two condoms at the same time.

The chart is deliberately presented as a comparison guide, not a medical guarantee. The exact condom's manufacturer dimensions, material, instructions and real-world fit should take priority over the chart output.
