Every now and then I get a new comment on one of my posts and in most cases a visitor is asking for a condom recommendation, giving his penis circumference and length.
It’s becoming tedious to reply everyone individually, so I’ decided to put here a table which shows suggested condom width in relation to penis circumference.
How this works
- 1. first, of course, you have to know your size. Read here about how to measure it
- 2. Once you have your circumference check where it stands on the table below.
- 3. To the right you’ll see suggested condom width for your size, both in inches and milimeters. Clicking on these numbers will lead you to the appropriate section in the condom size chart.
You can use the figures below as a guidance, but be sure to do your own research as well. First hand experience will always be the best judge. Also, I’m not responsible for any misuse 
| Penis Circumference (inches) | Suggested Condom Width (in) | Penis Circumference (mm) | Suggested Condom Width (mm) |
|---|---|---|---|
| <4 | 1.77 - 1.85 | <102 | 45 - 47 |
| 4.1 – 4.5 | 1.85 – 1.93 | 104 -114 | 47 - 49 |
| 4.5 – 4.7 | 1.96 – 2.05 | 114 – 119 | 50 - 51 |
| 4.7 - 4.9 | 2.05 - 2.09 | 119 – 124 | 52 – 53 |
| 4.9 – 5.1 | 2.09 - 2.13 | 125 – 130 | 53 – 54 |
| 5.1 – 5.5 | 2.15 - 2.28 | 130 – 140 | 55 - 58 |
| 5.5 – 5.8 | 2.28 – 2.37 | 140 – 147 | 58 – 60 |
| 5.8 – 6.1 | 2.37 – 2.53 | 147 – 155 | 60 - 64 |
| >6.1 | 2.53 – 2.72 | >155 | 64 - 69 |
Note: in some cases you won’t find a condom with the suggested width. Then go with the closest you can find.
How did I get these numbers
Some of you might be interested to know how I got these numbers. Well, a study published in the International Journal of STD & AIDS tried to find how penis size influence condom slippage and breakage. After conducting their experiments, the authors concluded that the ideal ratio between condom circumference and penis circumference should be from 80 to 90%. More than that increases the risk of slippage, and if the ratio is less than 80% there is a greater risk of condom breakage.
If we take an average penis girth of 4.9 inches and compare it to average condom circumference (4.1 inches) we see that they’re within the suggested ratio.
I’ve applied this factor to all (well, almost all) possible sizes and got the above table.
