Sitting Hip Breadth
The breadth of the hips while sitting.
SittingHipBreadth
How to measure
Application
Used in seat width design for chairs, vehicles, and aircraft to accommodate the spread of the hips and buttocks when seated.
Posture
Sit on a firm, flat surface with weight evenly distributed.
Landmark
Measured across the widest point of the hips and buttocks as seen from the front.
Tool
Tape measure.
Clothing
Remove bulky clothing around the hips.
Common mistake
Expect this to be wider than standing hip breadth due to tissue spreading when seated. That is correct and expected.
