ThighLength
How to measure
Application
Used in seating design, prosthetic thigh sizing, and trouser leg proportioning.
Posture
Stand upright or sit with the thigh horizontal and parallel to the floor.
Landmark
Measured from the greater trochanter (outer hip joint) to the lateral knee joint, along the outer thigh.
Tool
Tape measure.
Assistance
A second person should locate both landmarks and hold the tape ends in place.
Common mistake
Measuring along the inner thigh gives a longer result. Measure along the outer side only.
