How To Measure For A Cock Cage (Fitting & Sizing)

Ever wondered how to measure for a cock cage, so you get the right size? I’ve been through that, so let me show you how I solved this problem.

Measuring for a cock cage is simple:

  • Measure while flaccid and take two measurements. 
  • Go lengthways from the base to the tip.
  • Find your girth (thickness) at the base.
  • Check three times to be sure of accuracy. 
  • Once you get the same result three times in a row, you can fit your cage.

Let’s Have A Closer Look!

A long time ago, chastity was only for maidens and enforced by knights. Now, anyone can have some fun with it – including guys who want their lady to control them. 

A cock cage is a perfect way to achieve this.

If you’re wondering how to measure for a cock cage but feel uncertain, don’t fret. It’s simple once you know the anatomy of both the penis and the cage. 

If you take your measurements correctly, you’ll end up with a comfortable cage that works.


Two Main Components of Cock Cages

  1. Cage – This is the part that goes over the penis. It’s the most visible, and there are plenty of different designs to choose from, from fully enclosed to cages with open sections for breathability. 
  2. Ring – The other part of the whole cage package that’s arguably even more important to get right in terms of measurement. The ring goes around and behind the scrotum to hold the whole thing in place. It’s the base that ensures no escaping. It’s very important because a ring that’s too loose means you can slip out of it, but too tight can actually be dangerous as it will cut off your circulation.

Types of Cock Cages

There are many different kinds of cock cages, which we can divide up based on material, function, and features. 

  • Steel – Reliable, heavy, and sexy to look at. 
  • Plastic – Affordable, a little more forgiving, and comes in many colors. 
  • Silicone – Not as common as plastic or metal. Comfortable, more elastic, and easier to use than steel. 
  • Leather – Used for harnesses quite frequently, much less common to see a cage made out of leather. 
  • Open-sided – Has windows to allow air in and keep things more fresh. 
  • Closed cages – For a feeling of total enclosure. Will get sweaty, though. 
  • Inverted chastity cages – Pushes the penis all the way in so it looks like there’s nothing there in profile. 
  • Electro-shock cages –  Usually remote-controlled so Dom can give electric shocks. 
  • Cages with urethral plugs – Stops you from peeing or ejaculating. 
  • Cages with sounding rods – Like urethral plugs, but they go much further, i.e., sounding.

Types of Base Ring

There are three kinds of base ring shapes to consider. These are: 

  • Circular – The most common type. A circle that you push your penis and testicles through, then lock in place. 
  • Curved/Oval – A bit more ergonomic for many people. These have a different, more oval shape, so the sides are narrower, but there’s more room at the bottom. Probably better if you have a lot of skin. 
  • Curved Hinged – Instead of pushing your bits through the ring, you open it up, put it under the scrotum, then close it and lock it in place. They’re usually similar in shape to curved or oval. Just watch out for the hinge so that it doesn’t pinch the scrotum. Ouch.

Key Measurements You Need to Take

  1. Base ring – you’ll need to measure the distance around the base, so over the top of the penis and under the scrotum. 
  2. Cage length – You will need to know how long your penis is when completely flaccid, from base to tip.
  3. Cage diameter – You need your penis girth for this above all else. Diameter is probably a better measure than circumference because penises aren’t perfectly cylindrical. 
  4. Ball trap gap – The gap between the cage itself and the ring. This is important to measure for comfort, especially if you plan to wear it for a significant time. 

What You Will Need to Follow This Tutorial

The Tape Measure

It doesn’t take a lot of equipment to measure a cock cage. The primary tool you’ll require is a measuring tape.

Don’t use the measuring tape you might have in your toolbox. It won’t be accurate because you can’t wrap it around your penis – and you need to know your exact girth for a cock cage.

The edges are sharp, too – do you want to risk that down there?

You should also avoid using a ruler because that won’t work for girth. 

The best measuring tape to use will be one people use to measure clothes sizes. They’re long and can wrap around snugly for an accurate reading.


The String

It can be tricky to measure your girth with even a soft tape measure. How do you slide it off while holding the right number?

Get a soft string with no elastic because elastic will change the measurement’s outcome. You’ll need two pieces and make them long because you’ll need to tie a knot in one. Strings about 12 inches long should be plenty.

Get something to measure the string. Any measuring device will suffice.


How to Measure for a Cock Cage

Step 1: Measure the ring size

Aside from the soft and flexible sewing tape measure and string mentioned above, you will also need a marker pen for this

Start with the top of the string or tape measure at the top of the base of the penis. Then loop it around under the scrotum and bring it back up, so it makes a ring around your penis and testicles. 

You can then tighten or loosen it based on your preferences, but make sure that it doesn’t feel uncomfortably tight. If it does, loosen it a little as otherwise, you might find it cuts off your circulation, and we don’t want that. 


Step 2: Measure the length

Using your sewing tape measure, place it at the pubic bone. Don’t press it into the flesh above the pubic bone, as this will distort the measurement. 

Then you measure the length of the top of the penis all the way to the tip.

IMPORTANT: You have to be completely flaccid for this to work. No semis, no taking a hot shower beforehand. Make sure it’s the normal flaccid length as best as you can. 

Once you’ve got your measurement, take off about a quarter of an inch as this will ensure a tighter, more secure fit. That’s actually better than it being too loose. 


Step 3: Measure the diameter

There are two ways to do this. 

First, it can be as simple as using a ruler to measure the width of the shaft from one side to the other. This is usually alright for other toys but might be less accurate than the other way for cock cages. 

The second way (probably better) is to use a string or sewing tape measure to make a loop around your shaft at the widest point (when completely soft). Take note of that measurement. 

Then you divide by 3.14 to get the diameter of the internal part of the cage should be. Easy. 


Step 4: Measure the space between the cage and the ring

The “gap” means the distance between the back of the cage and the back ring. This is mostly  down to personal preference, but the golden rule is this: 

If your testicles hang high up and close to your body most of the time, then you want a bigger gap. 

And if they hang loose and further away normally, then you want a smaller gap between the cage and the ring to keep things in place properly. 


Step 5: Measure three times to ensure accuracy

All done? Great! Now go back and measure all of these again.

It’s generally a good idea to get all of these measurements at different times of the day to get a better idea of your average size since this changes throughout the day. 

So maybe measure once in the morning, once around lunchtime, and finally before you go to sleep at night. Whatever you think is fitting. 

Then you take the average of these three measurements for every criterion by adding them together and dividing by 3. This should get you a better fit than using just one measured figure.


How to Choose Your Size

Now that you’ve got your measurements, it’s time to order the right size cage for you. 

Unless you’re willing to put down a lot of cash and pay for a custom-made cage for your exact measurements, you’ll be getting one off the shelf. 

So you want to make sure that the numbers are as close to your own measurements as possible. 

If your exact size for the base ring is between two that are offered, you should go for the larger size ring. It’s better to have one that’s a little bit loose than one that makes your dick turn blue, and you have to go to the hospital. 

For a cage, it’s the opposite – too tight on your penis is better than too loose. After all, what’s the point if you have space to start to get erect? 

Plus, if a cage is nice and tight, it’s easier to line up your urethra with the opening. And trust me, that makes going to the bathroom a LOT easier.


Top 3 Chastity Cages

CB-6000

The benchmark of what a good chastity cage should be. It’s made from highly durable polymer that is very strong and also doesn’t look cheap, so you can see that it’s high quality. 

And it’s comfortable enough for daily wear, no problem. That’s thanks to the convenient array of components they ship to you, allowing you to mix and match pieces to get your ideal fit – all without having to order more parts. 


Locked in Lust The Vice

A truly inescapable prison of a cock cage with an innovative anti-pullout system. It also comes with many different parts for you to try and build your customized prison. And it does all of this while being light and easy to walk around in comfortably, even under clothes. 


Holy Trainer v4

The Holy Trainer is made of natural resin instead of plastic, which feels nice on the skin. The design is enclosed for a more complete feeling of entrapment, unlike the more forgiving CB-6000. That does mean you’ll have to clean it more carefully, of course. 

The Holy Trainer has 5 different sizes to choose from and a huge variety of color options, and it’s so easy to just put it on and get locked up. Ideal if you’re in a hurry or don’t want to fiddle around with different parts.

Personal Cock Cage Preference

So far, we’ve covered the essentials of how to measure for a cage to choose from. 

But what about style? And personal preferences? How do you choose a cage that expresses you? 

Lock Type

Most cock cages either have a sliding barrel lock, which is smaller and more discreet. That makes it easier and more convenient to wear out in public without drawing attention to the crotch department. Plus, it doesn’t make a noise when you move around. 

A padlock has the opposite effect. It’s bigger, bulkier, and not that convenient. And padlocks tend to make a noise by hitting the side of the cage when you walk or crawl around. 

So why choose a padlock? Well, it’s a matter of aesthetic choice and psychology. Something about seeing yourself locked up with an actual padlock has a different effect on submissives than a simple sliding barrel. So the choice is yours. Or your keyholders, more likely. 

Color

Many cages come in a variety of colors, and some, like the Holy Trainer, let you choose from a lot of options. That means you can get exactly the right color to accompany you and describe your particular predicament.


Locking It Up

Well, that’s all there is to it. Once you’ve got the numbers down, you should know your size in any brand’s cage. 

Just remember that sizing differs, so your final measurements will not be the measurements you go by forever! 

They’re the basis for all future purchases. But the cage doesn’t fit, go a size up or down until you find your perfect match again.

So gentlemen, have fun. And ladies… have even more fun.
