Frequently Asked Questions
Why does body frame size matter?
Ideal weight charts often assume an average frame. Knowing whether you have a small, medium, or large frame helps you interpret those ranges more accurately, since a large-framed person naturally carries more bone and muscle mass at a healthy weight.
How do I measure my wrist for this calculator?
Wrap a tape measure around your wrist just below the wrist bone (where a watch would sit), keeping the tape snug but not tight.
Is this the same for men and women?
No, the thresholds differ by sex because men and women have different average bone structures for the same height.
Can I use this with my height in feet and inches?
Enter your height in centimeters. If you know your height in feet and inches, multiply the total inches by 2.54 to convert to centimeters first.
