Cock rings
The best way to do this is; measure the circumference around the base of the penis and testicles (as far back as you can go) with a piece of cord – then take a note of the length and divide by pi.
Length / 3.142 = Diameter
Now, the thing to remember when measuring for a cock ring is that you don't want one that will be too tight. Of course, if it's not tight enough it wont work. But it's better to start off with one that's too loose and size down to one that has the desired effect.

The same technique for measuring cock rings is used again – with the exception, that we don't measure at the base of the penis. The point for measurement is between the penis and testicles. You will need to pull the testicles down and measure the circumference and also the distance betwixt the body and the testis. So once you convert the circumference measurement using the formula above you should have two measurements;
The internal diameter: As with the cock rings, it may be wise to allow a little extra on this.
The Depth: Don't go for one too deep to start with.
