Body Shape Calculator FAQ
Common questions about this calculator and how to use the results.
Is hourglass the healthiest?
No shape is inherently healthier. Fitness depends on many factors beyond proportions.
Do I measure over clothes?
Light clothing is OK; bulky layers skew results.
What if I am between shapes?
The tool picks the closest match—you may blend traits.
Is this for men too?
Men can use it, though labels like pear/hourglass are more common in womenswear guides.
Does shape predict health risk?
Waist size matters more for metabolic risk than a style label alone.
