Girth Calculator
- Take the circumference of the sleeve and divide that by 3.14. This will convert the circumference to the diameter of the sleeve for the rest of the equation (For example lets use the Barney sleeve which has a circumference of 5.6", divide that by 3.14 which will give you a diameter of roughly 1.8")
- Take that 1.8 and subtract the interior opening you will have cast into the sleeve. (For the example use 1.125" diameter interior opening, 1.8 - 1.125 = .675". .675" is the thickness of the silicone in the shaft area of the sleeve).
- Take the difference from step 2 which is .675 and add the diameter of your penis (for example say 1.7" diameter penis plus .675 = 2.375" in diameter once the sleeve is on. This number can be safely reduced by 10% to reflect variables that will inhibit that much expansion. 2.375 x .1 = 2.14" girth expected once the sleeve is on.

We purchased this in glow blue. Certainly a fun girthy glowing experience when this toy lights up! We certainly loved the girth and length of this toy!

Awesome this far I’ll definitely go for a softer shore and 1.25 next round

After overthinking too much, we just went ahead with this. Did not go for dual density, which is still great. Funny how there are second and third round effects: now we have a waterproof fitted sheet and a rotation of sheets to replace the ones from the night before.

This is one of my favorites. Very realistic and perfect fit for comfort on both sides. Definitely glad I went with the TDTZ. It is worth every penny.

The Dragonslayer is a favorite of ours. We did get it shortened as it’s a beast in length and girth. But the shape and girth is a great step up from the guru!
