Calculate an estimated ideal body weight based on height and sex, plus a healthy weight range based on BMI.
The calculator uses the Devine formula, originally developed for medical dosing, but widely used today as a general estimate of ideal body weight:
The calculator also shows a healthy weight range based on a BMI between 18.5 and 25, which gives a broader and more flexible span than a single number. Ideal weight is still just a general estimate — body build, muscle mass and bone structure vary a lot from person to person.
The Devine formula accounts for the fact that men and women on average have different body composition, including muscle and bone mass, at the same height.
Not necessarily. Ideal weight is one specific number from a formula, while the healthy weight range based on BMI gives a broader span that better accounts for individual variation.
Athletes with high muscle mass can weigh more than their "ideal weight" without it being unhealthy. For this group, body fat percentage is often a better measure — try the body fat calculator.
