How to measure your penis for cock ring sizing

When it comes to cock rings, the only size that matters is your girth - or, to use the math class name - circumference.

Now, it's worth noting that most penis rings fit around the base of an erect penis - but there are exceptions to this rule. Some rings are actually designed to fit around both your cock and balls - so these won't be the same size as one designed for your shaft only.

Don't worry though - in the next section, we'll explain how to go about sizing rings in both styles.

How to Measure Your Penis Circumference (Girth)

Measuring the base of the penis for a cock ring is actually fairly straightforward - but that task's much easier if you have the right equipment. You'll need:

• A piece of string or fabric ribbon (avoid anything made of a stretchy material)
• A pen or marker
• A ruler
• Your phone's calculator app

Note: You can use a measuring tape/tailor tape instead of string - but the width of the tape sometimes makes it difficult to place it and read an accurate measurement.

Step 1

Remove your underwear. Don't be tempted to tuck the waistband under your balls as you measure, as this can shift your balls any body fat you have around a little, making it harder to get the measurement just right.

Step 2

Taking the piece of string, wrap it around the bottom of the shaft of your penis where a cock ring will sit. Make sure the string is firmly against your skin without compressing your penis. Where the end of the string meets itself, make a mark with your pen.

Step 3

Remove the string, and then, using your ruler, measure the distance from the end of the string to the mark you made with your pen. This measurement is the circumference of your penis.

Cock Ring Size Calculator

Cock ring manufacturers sometimes use a girth/diameter measurement when sizing ring devices - but more often than not, you'll see width measurements listed instead.

Don't worry though - you can convert your circumference size into diameter size easily using your calculator. To get the diameter (width) from the circumference (girth), you simply divide the circumference measurement you've just made by 3.14.

Here's an example - where the penis circumference is 6 inches:

6 inches ÷ 3.14 = 1.9 inches

Here are some guideline circumference and diameter sizes:

Remember: Tension levels are important

When browsing online, you might find that your penis width is an exact match for a ring that a manufacturer produces - but more often than not, you'll have to choose an option that's as close as possible.

If this is the case, start by checking the sizing guide on the website you're looking at. Some manufacturers (especially those that offer tungsten ring options or other metal rings) will have unique fitting guidelines.

While cock rings are designed to prevent the blood from leaving the penis, it shouldn't stop blood flow completely. A ring that's fractionally bigger is a better option than one that's too small and likely to be uncomfortable.

Measuring Hard vs. Measuring Soft

In our step-by-step above, we've explained how to measure for a cock ring when your penis is erect. This is the most accurate way of measuring - quite simply because most cock rings are designed to fit around your erect penis.

Cock rings will almost always be measured with erect penises in mind - but if you find a manufacturer that lists flaccid sizes, you can repeat this process when you're soft. This can be useful if you're measuring for a ring that you're going to wear a ring when flaccid, either recreationally, as part of BDSM play, or simply for aesthetics.

How to Measure for a Cock and Ball ring

Cock and ball rings work differently to cock rings. Instead of wrapping around just your shaft, they go behind your balls and around the top of your penis.

If you need to measure for a cock and ball ring, you'll just need to make sure you loop the string under your balls and over the top of your shaft to mimic how the ring will fit. Aside from that, everything else is the same. Using this usually larger circumference, you'll be able work out the diameter needed so your cock and ball ring fits properly.

Why is it important to get the right cock ring size?

If you can spare just a few minutes to measure your penis, you'll have a better cock ring experience for a variety of reasons:

1. Better results

As we've already mentioned, tension is important with a cock ring. The right ring will offer better results by constraining the blood flow to the penis without stopping the blood flow completely and risking any numbness.

2. Safety

A cock ring that's too tight could lead to bruising if it damages the delicate blood vessels under the skin. Equally, a ring that's too big may move around during sex or masturbation, irritating or chafing the skin.

3. Comfort

A ring that's too tight can be uncomfortable or even painful. On the other hand, one that's too loose might not provide the desired effect and could slip off. The right size will ensure maximum comfort during both wear and removal.

4. Measure twice, buy once

Continually buying different sizes of cock rings due to improper fit is an unnecessary expense. Investing just a few minutes in finding the right size before you start shopping will usually save money in the long run.

5. Longevity

Although made from tough materials, cock rings are designed to fit snuggly without being overly stretched. If continually stretched too much, they may degrade and wear out faster than intended.

What influences the tension of a cock ring?
