The first step in choosing a condom! Understanding the relationship between the four sizes and diameter.
The diameter of a condom refers to the length from one end to the other when the condom is inflated with air.
To find a condom that fits you properly, the diameter (width) is important.

事例
Let's take an example where the thickest part of the erect penis measures 11cm (110mm).
Why do condoms with a diameter 1-3mm smaller than the penis diameter fit?
The reason is that condoms stretch when worn. If you choose a condom with the exact same diameter as your penis, it may feel loose.
After trying out 100 different condoms, I determined that condoms with a diameter 1-3mm smaller than my penis diameter fit well.
Please note that this is personal judgment, so there may be some margin of error.
Table for finding condom size and diameter based on erect penis circumference
Measure the circumference of the thickest part of the erect penis using a measuring tape. Match that circumference to the table below to find a list of condoms that fit you.
| Perimeter During Erection | Diameter That Fits | Size |
| 8..8cm-9.1cm | 27mm | S |
| 9.2cm-10cm | 27mm / 28mm | S |
| 10.1cm-10.3cm | 30mm / 31mm | s |
| 10.4cm-10.7cm | 31mm / 32mm / 33mm | S / M |
| 10.8cm-11.9cm | 35mm / 36mm | M |
| 12.0cm-12.2cm | 36mm / 37mm | M/L |
| 12.3cm-12.5cm | 37mm / 38mm | L |
| 12.6cm-12.9cm | 38mm / 39mm | L |
| 13.0cm-13.2cm | 39mm / 40mm | L |
| 13.3cm-13.5cm | 40mm / 41mm | L |
