Frequently Asked Questions
What is body frame type?
Body frame type (small, medium, large) describes your skeletal structure size. It is determined by bone size, typically measured via wrist circumference.
How do I measure my wrist?
Wrap a measuring tape around your wrist just below the wrist bone (the bony protrusion on the side). Measure in centimeters.
Why does frame type matter?
Frame type affects ideal body weight ranges. People with larger frames naturally weigh more at the same height.
What method does this calculator use?
This calculator uses the height-to-wrist circumference ratio method, which provides a simple and commonly used frame size classification.
