Popliteal Height
The height from the sitting surface to the back of the knee.
PoplitealHeight
How to measure
Application
Used in chair seat height design to ensure feet rest flat on the floor without pressure behind the knee. Critical for classroom, office, and vehicle seating.
Posture
Sit on a firm, flat surface with knees bent to exactly 90° and feet flat on the floor.
Landmark
Measured from the floor to the back of the knee crease.
Tool
Rigid ruler or tape measure.
Clothing
Remove shoes, or measure and subtract heel height separately.
Common mistake
Sitting on a soft surface compresses and underestimates the result. Use a hard chair or bench.
API example
