Cock Ring Size
Getting the right Cock Ring size is important for comfort and fit. Measure around your penis mid-way up your shaft for best results. You want to know the girth of your cock, not the length. Try both methods, string and paper to verify your size below.
​
How to Measure
String Method:
Measure Mid Shaft
​If your penis shaft girth (around) is about same from foreskin (after head) to base wrap a string around it, not tight, and mark where the string crosses itself.
If un-cut, retract your foreskin before measurements.
​
Lay the string flat and measure the length from mark to mark. Follow the chart below for the correct size. Use millimeters (mm) for best results.
If your penis varies in size from tip to base then make your measurements from the largest part of your penis shaft. If your Cock Ring sips or is too tight, order a free replacement.
Paper Method:
Measure by the paper method if your cock changes girth from the tip to base.
Cut a strip of paper about 8 inches long and about 1/2 inch wide. Wrap the paper around the mid-section of your cock. Mark where the paper intersects. Unroll the paper and measure the length from mark to mark. Use millimeters (mm) for best results. ​
