An Easy way to properly estimate a goaltender's size for a pair of goal pads is to take the following three measurements:
1. Floor to mid-point of knee cap (A)
2. Mid-point of knee cap to desired height on thigh (B)- measurement is generally 2/3s of the inseam measurement from mid-point of kneecap up. If a taller pad is desired, 3/4 of this measurement can be used
3. Skate size multiplied by 0.75 (C) - only add up to size 10 skate as a goal skate cowling does not get larger over size 10
The estimated size of pads would then be (A) + (B) + (C).
