The Condom Size Wizard

The Condom Size Wizard or how to find the right condom size
Welcome to the Condom Size Wizard, a tool to determine the best fitting condom to your erect penis.

The condom size is the width when laid flat. Therefore the condom size corresponds to half the condom circumference. 

As discussed here, Determination of a correct measuring system, the choice of the correct condom size depends greatly on the girth, or circumference, of the erect penis.



Please provide your erect penis circumference (girth):
The diameter of the erection is therefore: mm or inches

Depending on its size, a condom will be more or less stretched with this erect penis circumference. Please find below a chart reporting the stretch percentage depending on the most common condom sizes:

condom size (mm) 45 47 49 52 53 54 57 60 64 69
Condom stretch % % % % % % % % % %

As one can understand, not all condom sizes will fit a given erect penis circumference. As a matter of fact, the condom stretch should be between 10% and 20%, a good compromise between comfort and safety.

Condom Best Fit and other possible fits




Please provide your erect penis circumference (girth) to find out the perfect condom fit. Then you can select the perfect condom fit to see on the last list the other possible condom fits.


NB: this tool is only a general guideline. In case a condom company provides specific instructions about the condom and erect penis size correspondence, please follow them.

Also try out this Condom Size Calculator to see what exact condoms you should buy.

  1. There is no condom size for me.

    I have a natural 7" girth penis.

    I have only worn a condom once in my life with my first girlfriend. It was extremely near impossible to get on and could not feel anything once it was on.

    I just ended a long term relationship and would like to start wearing condoms again for obvious reasons. Could you recommend any condoms that will fit me.

    3. Have your partner wear a female condom - you won't need to worry about sizing.

  2. In fact, I can see three acceptable solutions to your issue:
    - Either have your partner use a female condom. There is a great chance she will accept when facing the cause of your request.
    - Or simply wear a MySize 69mm. The stretch ratio will be 28.9%, which may feel tight and uncomfortable, but not impossible. As a comparison, it would be like a 5.25in erect penis wearing a standard condom.
    - The last solution consists in buying a Coripa condom. They have 55 different sizes, and the biggest one might be as big or bigger as the MySize 69mm condom.

    No worries then.

  3. chart ends quite a bit early for myself as well.
    Anyone have the stats on the female condom? What's it's girth?

    1. Yes, the FC2 female condom is approx 172mm long. This is an ideal condom for larger men because instead of being placed on the penis, this condom forms and expands to fit the women's vaginal walls. Size dimensions found here: http://condommonologues.com/non-latex-condom-dam-size-chart/

  4. Could you be so kind and share a link to other sources that open up this topic of course in case you know some.

  5. Is this based on the girth of the penis
    1. half way down.
    2. a cm from the base
    3. at the widest point

    1. You can consider safely it is at the widest point (the different studies listed here differ though on this particular point).

  6. I think that your percentages based on penis girth are incorrect, because as seen in the video on 'condom size test' many of had a penis of about 15 cm in girth (which is in the 98%) and some had even more, so the probabilities of that happening are next to impossible, therefore your statistics are wrong, aren't they?

    1. Well, I would not be so naive... After all, they self-measured and publicly reported it on TV. I would take their words with a grain of salt...

      And anyway even if they didn't lie, the sample is so small that it has no statistical value.

      Don't forget it is not a scientific study whereas the studies reported here are truly scientific.

  7. hi i just wanted to thank you for the information this site provided for me,
    i finally found a condom my size,
    i am 6.5" mid shaft and 6.7" at the base in girth,
    i ordered online a trial pack for cas 7,8,9,
    got 3x60mm, 2x64mm and 2x 69mm, 7 condoms total,

    as your wizard stated a stretching factor exceeding 20% is not recommended and let me add IMPOSSIBLE to wear,
    for me 64mm were wearable but the erection wasn't full and even with long stimulation it impossible to beat the rubber grip,
    so anyone stating that they are of a certain big girth and still capable of wearing a normal condom are simply lying and busted,
    i found that 69mm are a good match for me, (i have series of pictures with each condom size as proofs)
    your theories are correct.

    so guys who says that they are 6" girth and that magnum XL fit them are liars,
    except for baseball bat shaped ones,
    so a penis constrained is a limp penis..if you want to bust someone lying about his girth just ask him about the condom he wears and check the wizard for stretching factor if it is exceeding 25% or 30% then it's BS..

    1. FWIW, I am 5.2" girth. I always thought the difference between normal and large was a big enough leap that it didn't make sense for me. I've almost always worn a 51mm condom, which is 30% stretch for me. While uncomfortable and a bit tough to get on, it wasn't painful enough to discourage me from having sex. A girl once gave me a snug fit which was about ~35% stretch. That was the point where I simply couldn't get it on. For me the limit was 30%.

    2. Yes you're right. There are straight numbers and there is sensitivity. Some,like you, bear a fairly high pressure. Other can't as they really fill pain, or are enough disturbed to loose their erection.

      I myself have a lower acceptance limit.

  8. Thanks for given such a lovely information about the penis length and girth.

  9. I simply don't understand, Joe of TheyFit said on Reddit that the nominal width of a normal durex is 56mm, and to know your nominal width you have to take your circumference (in my case 130mm) and divide it by 2.36, my nominal width is 55 according to that. Under the normal durex size?

    1. Explanation here:
      http://condommonologues.com/tips-decoding-condom-size/

      I have been interviewed by ondom monologues.
      Basically, the 2.37 division factor is only for TheyFit condoms, due to the reciepe used for their condoms.
      For other condoms, test it for yourself, it should be between 2.2 and 2.4.

  10. But why would they make a regular durex condom 56mm if most men are between 12-13cm? People with 12.5 cm in circumference say they slip off sometimes, my suspicion is that the averages are higher?

    1. It's a good question. It may also be that the elasticity of the Durex material makeup requires a slightly larger "average" width compared to other condom manufacturers.

  12. Hi, I have a question about the difference between 2 websites for my size of condom. I have a 152 cm girth penis approximatively. But my size recommends me to choose a 69 whereas they fit says I should take their "22" which is 64 (I tried their fit kit). It seems that the sizes are very ≠ because my size says a 69 is for 14-15 cm girth whereas they fit says their "31" (69) is for people until 7,5 inch girth. Can you help me to understand and choose the right condom for me ?
    Thank you very much
