Interested in purchasing a fixed sized cock ring? Knowing how to properly measure for size is important and easy to determine.
Using a tailors tape, a piece of string, a ribbon or even a shoelace, wrap it around the base of the penis and behind the scrotum and mark where they overlap at a snugness that's comfortable for you. Now line it up with a ruler to obtain the circumference measurement. Divide the measurement by 3.14 to obtain the diameter or ring size. We recommend you take the measurement when both soft and erect to determine the best fit for you. Keep in mind, the ideal cock ring stays in place when the penis is soft, yet it can fairly easily slip off or unsnap when the penis is hard.
Most fixed size cock rings are available in either 45mm (1.77"), 50mm (1.97") or 55mm (2.17").
45mm = 1.7717" diameter | 5-1/2" circumference
50mm = 1.9685" diameter | 6-1/2" circumference
55mm = 2.1654" diameter | 6-3/4" circumference
