Cylinder Sizing

Find Your Size Before You Order

Measure your erect circumference — at the shaft base or the head, whichever is larger — then match to the chart below.

How to Measure in 3 Steps

Use a soft tape measure or a piece of string. Measure while fully erect. Use the larger of your two measurements to determine your size.

1
Wrap around the shaft base Measure the circumference at the base of the penis while erect. Note the measurement in inches.
2
Wrap around the head Measure the circumference at the widest point of the penis head. Note this measurement too.
3
Use the larger number Match your largest measurement to the size chart. If between two sizes, select the larger size.
Circumference Size Cylinder Diameter
Up to 5" Small 1.75"
5.10" – 5.50" Medium 2.00"
5.51" – 6.25" Large 2.25"
6.26" – 8.00" X-Large 2.50"
Medium (2.00") fits over 80% of men. All cylinders are 9" in length. Still unsure? Call us at 1-800-294-7777 — Mon–Fri 7:30AM–5PM PST.
