Waist to Hip Ratio

Waist-to-Hip Ratio (WHR) is a dimensionless ratio calculated by dividing waist circumference by hip circumference, both measured in the same units. In biomechanics and ergonomics, WHR serves as a proxy for body fat distribution, influencing engineering design considerations for seating, protective equipment, and workspace optimization. A higher WHR indicates abdominal obesity, potentially impacting load-bearing capacity and range of motion assessments. This ratio informs the design of comfortable and safe products, ensuring inclusivity across varying body morphologies. Furthermore, WHR data contributes to statistical modeling for predicting population-level anthropometric requirements in mass production.
