Frequently Asked Questions
What is ideal body weight?+
Ideal body weight is an estimated healthy weight range based on height and sex. Four commonly used formulas (Devine, Robinson, Miller, Hamwi) give slightly different results. Use the average as a general guide.
How accurate are ideal weight formulas?+
These formulas are rough estimates that don't account for muscle mass, bone density, or body composition. A muscular person may weigh more than their 'ideal' weight and still be very healthy. Use BMI range as a complementary measure.
How do I know my frame size?+
Wrap your thumb and index finger around your wrist. If they overlap: small frame. Touch: medium frame. Don't touch: large frame. You can also measure wrist circumference — under 6.5 inches (women) or 6.5 inches (men) is small.
