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.

Great all around use, we use this more commonly than any other we are slowly building a collection. This is our ‘Old Faithful’ perfect fit for me and great stretch for my partner

Ordered and surprised was bigger than expected. Initially was not expecting for my wife to be comfortable but she was a fan and finished without hesitation
