So, I am going to show you how to properly measure for a chastity cage and reasons why chastity cage sizing is so important.

Types of Cages for the Right Chastity Cage Fit

Knowing how to measure for a chastity cage is just as important as finding the right type of cage for you. Whether you are choosing your own cage or it’s being chosen by your Dom, there are several different types of chastity cages to choose from. As a result, the chastity cage sizing and ring sizes will vary by material. So, here are some of the different types of chastity cages available:

  • Steel
  • Plastic
  • Polycarbonate
  • Silicone
  • Leather
  • Open-sided

  • Inverted chastity cages
  • Electro-shock cages
  • Cages with urethral plugs

Why Measure for a Chastity Cage?

Measuring for a chastity cage ensures that you get a proper fit all around. Now, chastity cages aren’t supposed to be as comfy as your favorite pair of underwear. No, they are meant to be uncomfortable. However, the chastity cage fit should not cause abrasions, blisters or cut off circulation to your penis. Simply put, a chastity cage should be snug enough as not to allow for an erection.

How Should a Chastity Cage Fit?

A chastity cage is built with a ring that goes around both the testicles and the penis. So, measuring for a chastity cage is crucial. Secondly, the cage is meant to encase the penis, from base to tip, with only a little room all the way around the shaft for air flow. Thus, with the right chastity cage sizing, you should be able to pee and go about your day. However, you should not be able to achieve an erection.

And that’s the whole idea of chastity, now, isn’t it?

Measuring for a Chastity Cage: Chastity Cage Size

Chastity cage measurements

What chastity cage size you buy depends on 2 chastity cage measurements; the cage itself and the ring. Therefore, you will be measuring your penis length and girth in order to get the perfect chastity cage fit. And no worries! Chastity cages come in all sizes from small to large. That way, whether you are short and thick or long and slim, you’ll find the perfect chastity cage size.

The Importance of Ring Size

The chastity cage ring size is just as important as the cage size, if not more so. That is because the ring goes around the penis and testicles. If the ring is too small, it can cut off circulation to both and cause permanent damage. Therefore, in getting the proper chastity cage measurements, you’ll be figuring out the right diameter for the ring itself.

Now, the reason for this is that chastity cage rings come in a wide variety of diameters for the perfect, safe chastity cage fit. Fortunately, many manufacturers are now making it easier to get the right chastity cage fitting by including different sized rings in a single cage kit.

However, the more elaborate cock cage kits are a bit pricier. So, if you’re a chastity cage beginner, you may want to keep the cost to a minimum until you know the type of cage you like best.

Preparation and Supplies

Now, let’s show you how to measure for a chastity cage. First of all, you need to be sure your penis is completely flaccid. It also helps if you haven’t just taken a shower or been exposed to cold water. Then, you will need the following supplies to get the right chastity cage measurements:

  • Thick string or cordage
  • Marker
  • Scissors
  • A 12” (or larger) ruler
  • Calculator (if you’re not the best at math)

Remember, you’ll need a thicker string or length of cordage as chastity cage rings are thick. This just helps to get a closer circumference measurement. Additionally, using a flat ruler for measuring is the most efficient way to get the proper chastity cage measurements. That is because measuring tapes don’t lie entirely flat.

Step 1: Measure for Your Ring Size

Step 1 measuring for a chastity cage

The first step in measuring for a chastity cage is to get the correct ring size. So, make sure you are completely limp – think about Aunt Ethel wearing nothing but support stockings – whatever it takes. Then, take a length of string and put it behind your testicles. Bring the string all the way around till it meets at the top of your penis.

Now, tie a loose knot in the string, making sure it isn’t too tight. You should be able to slip your pinky finger under the string with little resistance. Next, once you’re sure the string is comfortable, make a mark on the one side of the knot with a marker. Then, carefully cut the string at the line you drew. Finally, lay the string flat on the ruler, with the knot at the end.

You now have the circumference. So, you need to divide that number by 3.14 (pi) and you will have the diameter, which is how you get your chastity cage ring size.

Chastity Cage Ring Measurement Tips:

It’s best to do this 3 times in order to get the most precise chastity cage ring size. For example, measure once in the morning, once at midday and again in the evening. Since our bodies fluctuate in size, depending on the time of day, this will give you the best chastity cage fitting. Then, add all 3 measurements together and divide by 3. Then divide that number by 3.14.

Step 2: Measuring for a Chastity Cage Length

Now, you are going to measure for your chastity cage length. Remember, you don’t want any room to achieve an erection. Plus, having the tip of your penis touching the end of the cage makes urination easier and a lot less messy! Again, be sure your penis is completely flaccid to get the best chastity cage measurement.

Place the ruler under your penis, above your testicles and press it against your pubic bone. Look down and note the length of your penis. Next, to allow a wee bit of breathing room, add ¼ to 1/2” to that measurement. That’s it!

However, as mentioned during the ring measurement tips, it’s best to do this 3 times. Then, add those numbers together and divide the total by 3. This will give you the most precise chastity cage measurement.

Step 3: How to Measure the Diameter

Finally, the last step in knowing how to measure for a chastity cage is to measure the girth of your penis. This is to make sure you have the best chastity cage fit all the way around. Now, making sure your penis is still limp, take a peek down there and find the thickest part of your shaft. Note that can be the middle or even closer to the glands.

Next, as you did with the ring measurement, use a piece of string to wrap around the thickest part of your penis. Tie a loose knot, making sure you can easily slip your forefinger underneath the string. Now, mark the string on one side of the knot and slide it off your penis before snipping the string with scissors.

Finally, lay the string on the ruler, with the knot at the top. Next, take that number and divide it by pi (3.14) and you’ll have the diameter you need to ensure the safest chastity cage fit. Again, measuring for a chastity cage 3 times, then dividing that number by 3, will give you the most precise fit.
