Pump Size Calculator
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.
Fatigue Calculator
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.
