Taking Your Chastity Cage Measurements For a Perfectly Sized Cage

Golden Sevanda Cages

Gold Sissy Cage (Clitty and Beetle Variants)

If you’re thinking about buying a Total Chastity cage, we strongly recommend taking measurements of your penis before purchase. This is an important step of the chastity process which is often overlooked, and can lead to poorly fitting cages.

In this page, you’ll learn the importance of taking accurate measurements, and how to do it so that every purchase you make will restrict your penis snugly and securely.

The Importance of Accurate Measurements

You might think that as long as your measurements are close then it should work out. You can get away with clothes that are slightly too big or too small, so why not chastity cages? But a poorly fitted chastity device can cause several problems.

Perhaps most importantly, you’ll be compromising on comfort. When you’re going to be wearing this device for hours, days or even weeks at a time, why not take the extra care to make sure it’s comfortable?

A poorly fitted cage won’t just be uncomfortable though. It could fall off completely, cause pain when you start getting hard, chafe and irritate your skin, and cause hygiene problems as the pee hole doesn’t line up properly with your urethra.

Save yourself the trouble and measure carefully, multiple times, before buying anything.

The Parts of a Chastity Cage

Chastity cages are relatively simple, and most have two distinct parts. These are the tube, or body, and the ring. When wearing the cage, the ring will be at the base of your penis, and the tube will slide over your shaft and attach to the ring. Sometimes rings will be solid, so you’ll need to push your penis and testicles through the hole, and some rings are hinged, so you can just close them around the entire package.

When you’re shopping for a cage, you’ll usually see three measurements on our product pages:

  • Ring Diameter.
  • Cage Diameter.
  • Cage Length.

Sometimes you’ll also see a measurement for the gap between the ring and the body, which can be useful if you have particularly large or high hanging testicles, but most of the time you won’t need to measure for this part.

The two most important measurements are the ring diameter, and the cage length. Diameter can also help with comfort but in the majority of cases if you choose the right length, the diameter will also be correct.

What You’ll Need Before Measuring

The best way to take accurate measurements is to use a flexible tape measure. These are the kind you usually see tailors use to measure for clothing.

If you don’t have one of these, you can use a piece of string/shoelace, a pen and a ruler. Wherever you take a measurement with these, you’ll need to make a mark on the string with a pen and then lay it out flat alongside the ruler to see how long the measurement is.

How to Measure for Your Chastity Cage

There are four simple steps to take all of the necessary measurements for any chastity device.

1 – Flaccid Penis Length

Hold your flaccid penis in your hand at a 90 degree angle from your body (pointing straight away from you). Place the end of the tape measure against your pubic muscle, and lay it flat along the length of your penis.

This measurement is the cage length you are looking for.

2 – Penis and Scrotum Diameter

Place the tape measure on top of your penis against your pubic muscle. Wrap the tape measure all the way around your penis and testicles and note where it crosses over.

This measurement is the circumference of your penis and scrotum. You need to divide this number by 3.14 to get the diameter.

This final measurement is the ring size you are looking for.

3 – Testicle Gap (Optional)

This measurement helps you find the right gap size for your chastity cage—the gap size is simply the distance between the bottom of the ring and the tube. This measurement is usually non-critical for most, but if you have larger-than-normal testicles or testicles that are tight and close to your body, you may find that cages with small gaps put uncomfortable pressure on your testicles.

To measure for the gap, hold your penis and scrotum at the base with your index and thumb forming a ring around them, as if you are wearing a cock ring, then pull down and squeeze very gently until your scrotum is tight and unwrinkled. Measure the height and length of your testicles—the biggest one, if there’s any difference.

If they hang down with a height of more than 2”, or extend away from your body with a length of more than 1.5”, then you should definitely choose a cage with a large gap.

While not all chastity devices list a gap size, it’s usually easy to see from pictures if a cage has a large or small gap, relative to the device's size itself. Estimates can be made from the product's total length.

4 – Flaccid Penis Diameter (Optional)

Similar to the penis and scrotum diameter, place the tape measure on top of your penis, but this time at the widest part of your glans (the head of the penis). Wrap it all the way around and note where it crosses over.

This measurement is the cage diameter you are looking for.

Tips for Measuring Your Penis

  • Measure when you are completely flaccid.
  • Measure several times, at different times of day. Your penis naturally changes size throughout the day.
  • Consider the temperature when measuring. If it’s cold your penis will be smaller. If it’s warm your penis will be larger.

Tips for Making Sure Your Cage Fits Properly

  • If you are between sizes, choose the larger size. This leaves room for your penis to grow slightly during the day.
  • Aim for the tip of your penis to touch the tip of the cage. This will let you urinate through the hole at the tip.
  • When you try a new cage, pay attention to your body. Any discomfort or pain indicates a problem with the fit.
  • Don’t be afraid to try multiple cages. Finding one that fits well can massively enhance your chastity experience.

Michael is the author of the Total Chastity Diary and has been in and out of chastity since his mid-thirties. He’s now 41. He lives and works in Boston, has a white-collar job, and is single by choice. 

“There’s nothing hugely special about me. I’d describe myself as your typical modern, forward-thinking guy. I enjoy sports, staying healthy, love my family and friends, and have a satisfying career that pushes me to work hard so I can enjoy some of life's luxuries. 

I’m whatever constitutes as “normal.” It just so happens that I also enjoy the feeling of putting my cock in a cage, leaving it there for a week or two, then reaping the benefits of being released from my cage. 

Starting my chastity journey felt like starting any other new hobby or interest. I wanted to make sure I was doing it right and had good equipment to help me achieve the results I wanted. But when I began looking into male chastity and cock cages, what I found was a lot of fetish talk. 

While I accept this is what male chastity means for some - dressing up as a sissy, being spanked by a Dominant and whatever - the kinky kicks aren’t what I’m into. 

My hope with the Total Chastity  Diary is to bring a more matter-of-fact voice to chastity experiences.”
