RingFingerLength
How to measure
Application
Used in ring sizing for knuckle clearance, glove finger design, and medical digit proportion assessment.
Posture
Hand flat, palm facing upward, fingers straight and relaxed.
Landmark
Measured from the base crease of the ring finger to the fingertip.
Tool
Digital caliper or rigid ruler.
Common mistake
Measuring from the web between the fingers rather than the base crease shortens the result.
