How to choose the right size?
Most people will use a ring with a 45mm diameter. Here is a 4 step procedure to help you find the right diameter for you.
- 1. Use a measureing tape or a string about 30 cm (12 inches) long, and place it around your scrotum and penis. Remember not to use elastic string, as this would skew the measurements.
- 2. Make a double knot: the string should be tight enough to make it difficult for you to slip a finger under it, yet not so strong as to cut off the blood flow. Leave the string on for 5 minutes to make sure it is the right diameter.
- 3. Cut the string with a pair of scissors, taking care not to cut yourself!
- 4. Measure the length of the string, and consult the following table to learn which is the right diameter for you.
Length in mm | Length in Inches | Size Birdlocked |
119mm to 132mm | 4.68 to 5.2 inches | 40 |
133mm to 148mm | 5.21 to 5.82 | 45 |
149mm to 163mm | 5.83 to 6.41 inches | 50 |
164mm to 169mm | 6.45 to 6.65 inches | 53 |
