Shop How to Find Your Size

 

 

It's important!  

Proper fit is critical. If you aren't sure what size is best for you, take the time to measure and calculate.

 

Here's how, in three easy steps:

 

 

1. Prepare

A tailor's measuring tape is ideal. If you have none, you will need a string at least one foot long, a ruler and a marking pen. Now, make yourself erect.


2. Measure

You can measure in inches, centimeters or millimeters.

If using a tailor's tape, simply encircle it from under your balls up and around the top of the penis. Pull the tape until you have a very snug fit, but not an uncomfortable choke. Note the measurement.

If using a string, encircle it the same way. Pull the ends to get a really snug fit. Mark the string on both sides where they meet. Remove the string and measure between the marks.

Tip: Sometimes a more accurate measurement is taken when flaccid, so take several readings in arousal states of soft, hard or semi-erect. 

If you aren't sure if you're pulling your string or tape tightly enough, use the "one finger rule": When soft you should be able to JUST fit one finger under the string. But when hard you should NOT be able to fit even one finger under the string when it's tight but comfortable.

 

3. Use The Calculator Below

    More Measurements

    While you're at it, use the same technique for three more measurements:

    > around the shaft of the penis, at the base

    > around the penis, just over the glans head

    > around the scrotal sac, above the testicles

    Head and shaft rings can be worn when soft or partially or fully erect. Many guys like to have several sizes, and choose which to wear depending on their anticipated arousal state. Inside diameters 7/8 to 1-3/8 inch (20mm to 35mm) are the most popular sizes. 

    The scrotal sac measurement will be useful for choosing a ball stretcher. There is only a small variance here, with inside diameters often falling between 30 and 40mm, and 35mm being standard.
