Sizing Recommendations: 

Try our Size Calculator. 

ATTENTION *** FOR MEN WITH WIDE BASES:  Use your widest base girth.

Room for 10 to 15% Expansion is recommended.

So, multiply your current girth by 1.10 or 1.15 to get a cylinder that allows for expansion. (ex; 5 x 1.10 = 5.5)

So, a 5-inch girth multiplied by 1.10 is 5.5 and by 1.15 is 5.75 so this specimen would be recommended to get the 2.0 since it allows for room for growth and immediate pump gains.

We recommend not going over 30% of your current size with the internal circumference of the cylinder.

While we work on sourcing a smaller size, other companies SHOULD have options for men less than 4.0 Girth that matches our recommendations.

General consensus is to measure off your thickest points but for men with exceptionally wide bases and would like to focus higher on the shaft measure your mid-shaft instead of your largest point.
