To determine the right size, you measure the penis diameter with a ruler or the penis circumference. To measure the circumference just wrap a ribbon around the erected penis, mark the intercept and measure the length on the ribbon. A cock ring should always be smaller than the penis diameter. For example, if your penis has a circumference of 150mm/a diameter of 48mm then choose a ring with 45mm.
