Suggested Condom Width In Relation To Penis Circumference

condom width to circumference
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 :)

    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 they came through a combination of personal experiments and personal preference, feedback from readers and researching few studies that one can find on the topic of condom size.

    There aren’t many studies that dealt with this topic. An old study published in the International Journal of STD & AIDS tried to find how penis size influence condom slippage and breakage. In their results they concluded that “each additional centimetre of penile circumference increases the risk of condom breakage by 50 to 100%”.

    That would mean that a man with a penis circumference of 14 cm is about twice as likely
    to experience condom breakage as a man with a girth of 13 cm.

    Researchers like John Gerofi dealt with this topic in more details. He examined the available studies and tried to measure the pressure of condom on penis and how much it changes with different sizes.

    In his publication called Condom size he writes how condom circumference should be smaller than penis circumference so there is enough radial force which ensures the condom stays in place.

    The analysis suggests 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.

    Would love to hear your comments!

    Update: some guys are confused about how condom width is measured. Please read this post for more details.

    unsure what size
