Use this calculator to determine your correct pump cylinder width.
Room for 10 to 15% expansion is recommended. Do not exceed over 30% of your current size.
General consensus is to measure your thickest point.
ATTENTION *** FOR MEN WITH WIDE BASES: Use your widest base girth.
If you are trying to change shape or would like to focus higher on the shaft, measure your mid-shaft instead, while ensuring your base will still fit. And if you are relatively more oval-shaped or flat, or curved, you might need to go up a size to make sure it fits.
Use this calculator to target your proper fatigue levels.
Length:
Fatigue Target (out of device): 2-3% longer.
Strain Target (in device): 4-6% longer.
Girth:
Expansion Target: 4-8% thicker.
* More is not better. Reaching for the max does not mean a better session.
This calculator converts between inches and centimeters. Enter a value in inches or centimeters, and the corresponding value will automatically populate in the other field.
This calculator converts between kilopascals (kPa) and inches of mercury (inHg). Enter a value in either field, and the corresponding value will automatically populate in the other field.
We currently carry the common sizes.
Max Sizes per Cylinder:
** Leave room for expansion!
1.75 Erect Girth up to 5.5
2.0 Erect Girth up to 6.25
2.125 Erect Girth up to 6.66
2.25 up to 7

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.
