How To Measure For A Chastity Cage

Whether you are starting out in chastity play or a seasoned wearer of chastity cages, it's very important to know how to measure yourself in order to have a perfectly fitting chastity cage. Don't have an uncomfortable cage, follow our tips and get it right from the start.

Chastity Cages Co sell chastity cages in a variety of shapes and sizes and for 99% of people there will be a great cage for you which you can get a lot of enjoyment from.  Our cages range from roughly half an inch in length to 5 inches in length, whilst the size of the rings for the cages will range between 36mm and 55mm.

So with so many options, we want to help you find a cage of which you both love the look and fit and can happily wear for months to come.  And so to achieve that perfect fit, you'll be making four measurements which are as follows:

1. Cage length,

2. Ring size

3. Internal cage diameter

4. Cage gap

1. Measuring the chastity cage length

So how long is too long and how short is too short? You want a chastity cage which fits snuggly.  Having a cage that is longer than your flaccid penis only allows for some expansion while getting semi-erect and in our view being able to gain any erection is not in line with the purpose of male chastity. 

The male penis is very much malleable when flaccid, so compressing to a small cage than the natural flaccid length is a possibility, but we would advise on trying to compress too much as this can be restrictive for blood flow.  You will know you have the perfect length when the tip of your penis in a flaccid state is touching the end of your chastity cage without pressing heavily against it.

For that same reason, to measure for your cage, you must ensure that you are in this state without being aroused.  This can be difficult but please take the time to allow any erection to subside and look for the most natural state possible before taking a measurement.

If you have a measuring tape, excellent, this will be slightly better than using a straight ruler but if a ruler is all you have at hand then don't panic, we can still get good measurements.  Start measuring from your pubic bone, running along the top of your penis to the tip.  Take a few different measurements during the day and aggregate them together as there will be natural variations.

When you have this measurement, it is common practice to subtract 1 quarter of an inch when you start looking at cages.  We want that fit to be snug, and we want the tip of your penis pressing slightly against the tube of the cage.  

And with that final measurement, penis length when flaccid minus 1/4 inch, you are ready to look at the lengths of chastity cages in the store.


2. Measuring the chastity cage ring

This is arguably the toughest part to get right as we really want a ring to be neat fitting around the testicles in order to hold your cage in place and grip your body whilst remaining comfortable and not compromising blood flow or your ability to use the bathroom.  

It's a common misconception that a tight ring will cause friction with the body as you wear it each day.  We tend to observe that a snug fitting ring will actually cause less friction on the body as it simply moves less.  Although loose, a ring that is too large will constantly move back and forth and irritate the skin.

To measure the distance around the base of your testicles, you will need that measuring tape again or if you do not have that, a piece of string which you can mark then measure against a ruler.  

Once more ensure that you are in a room where the temperature has been fairly neutral for some time and remove clothes to allow your body to equalise with the ambient temperature for a few minutes first.

Take your penis and testicles in one hand, think about clasping them all within your hand and gently pulling them away from the body to expose the line you are going to measure around.  Take your string or tape and run it around from the pubic bone at the top all the way under and back to meet at the top.

Mark your string with a pen when it crosses over and if you are using a tape then note the measurement as it crosses over the starting point.  Once more, repeat this process a couple more times throughout the day and average out that measurement.

Now comes time for a little maths to get the ring diameter.  The measurement you have recorded is the circumference.  So that's in essence a circle and we want to know the diameter - the distance from one side to the other in a straight line.  To find this we need to divide by 3.14 (pi) and that's the magic number.

For example, let's say you average out a measurement of 159mm.  Divide that by 3.14 and you will get a measurement of 50.5mm.  Based on that, the ring size that is best going to suit you is the 50mm ring, often known as 'large'.

Know your chastity ring types.

There are two shapes you will see recurring often in the world of chastity.  Circular and arced rings. Both sizes are comparable, the sizing doesn't change much based on shape, but feel a little different on the body.

Circular rings are the classic shape that most of the original chastity cage designs utilised.  A uniform circle, very easy to measure for and it's hard to go wrong.  

Arc rings are a smidge more long from top to bottom than circular rings, but conversely taper in a little as they go down so they slightly redistribute how the press against the testicles but ultimately give a very similar result.  

A 40mm circular ring, is directly comparable to a 40mm arc ring but it's always advisable to test out cages with each type to see what you personally prefer, but your measurements are good for either type.

The most common sizes you will encounter are 40mm, 45mm and 50mm.  These are also know as small, medium and large rings.  In some cases, cages will be compatible with sizes outside of that spectrum, including a 36mm, extra small ring, and a 55mm, extra large ring.  These cater to people who fall outside of the mean range of sizes but options are just a little more limited in these sizes.

 

3. Measuring for the internal cage diameter

Now that you are reacquainted with pi calculations, we will be repeating that once more, this time for the shaft of your penis.  Again ensure a relaxed state in a room that is not too cold and not too warm.  Using a measuring tape or string, wrap it around your penis and note where the measurement crosses over on your tape, or mark a string with a pen then measure it against a ruler.

Repeat this process a further 2-3 times throughout the day and average out the measurement before dividing by 3.14 to give you the flaccid diameter of your penis. 

As a reminder, we are looking for a snug fit.  Keep in mind that your penis will squeeze into an area slightly smaller with no discomfort so do not worry about that.  Our goal here is to stop any erection dead in its tracks.

4. Measuring the gap between cage and ring

This is an often overlooked part of the chastity fitting process and addresses the gap that exists between the closed cage, once it has been locked shut, and the ring that it is affixed to.  It is through this gap that your testicles will sit.  The role of this gap is to clasp your ball sack to prevent escape.  Narrow enough to not allow a gap for your testicles to slip through, and wide enough that it's not squashing the skin of your testicles uncomfortably. 

Some people find the challenge here is down to how tightly their testicles sit against their body.  While some may find initial discomfort as their testicles naturally try to retract a little, the chastity cage stopping this movement, others will find that their testicles sit naturally below the line of the ring comfortably from the outset.  

For everyone though, your body will adjust over the first week of wear and things that perhaps initially feel uncomfortable will settle as you get used to wearing the cage.  By the second week most people will almost forget that they are wearing it.

 

Other considerations

Material 

Silicone, resin or steel.  Roughly speaking that is the material choices for your chastity cage.  Each has their own advantage, whether it be practical or an aesthetic choice.

Silicone cages are typically soft and lightweight and therefore quite malleable under clothing. They also often come in a wide variety of colours giving you some interesting aesthetic choices.  Great for a beginner who is perhaps a little daunted about undertaking their journey of male chastity.

Resin cages are kind of high quality composite that feels hard like plastic but has a resilience approaching that of steel and firm, fixed shapes that do not bend and give the security of steel but with the lightweight feel of silicone.  Unsurprisingly this is a popular choice for many.

Steel chastity cages are perceived as the top tier of chastity cages.  Often this is more symbolic than anything but one cannot deny the allure of a beautifully crafted steel cage locked firmly onto their partners prized parts. Immovable, inflexible, thus is the aesthetic representation of chastity.

Color

Chastity cages occasionally offer you the opportunity to get a little creative on the color front.  Whilst steep cages are generally the typical silver color you would expect, special editions do become available on ocassion and offer you the opportunity to get a steel cage in black or gold.  

More typical colours are available on silicone and resin cages, with blue, black, clear, and pink being common to see. For those who include an element of feminisation in their chastity play, pink is a popular choice.  Our tip, give it a try, it's a lot more popular than you might think!

Lock

The locks on chastity cages will either be internal or external.  An external lock looks like a good old fashion padlock.  Typically there will be a small loop built into the top of the cage where the ring and cage connect and a lock will loop through there before being closed.  Such a lock provides an interesting look to the cage, especially for a key holder but keep in mind when your cage is steel, the movement of the lock will create a little noise as you move!

An internal lock forms a small tube between the ring and cage when they are connected.  A lock piece is then inserted into that newly formed tube and turned with the key ensuring it cannot come out and the cage cannot open.  This internal lock has become widespread in recent years and you will see it on most of our cages here in the store.
