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.
