ThumbTipToCrotch
How to measure
Application
Used in glove design to size the thumb section independently, ensuring correct thumb length and web space proportions.
Posture
Hand flat, thumb extended naturally to the side.
Landmark
Measured from the tip of the thumb to the webbed junction between the thumb and index finger (thumb crotch).
Tool
Rigid ruler or digital caliper.
Common mistake
Measuring to the base of the thumb rather than the web junction gives a longer and incorrect result.
