Expert FAQ: Everything About Ideal Weight

How is Ideal Body Weight (IBW) calculated?
Ideal Body Weight (IBW) is estimated using several common formulas, including the Devine, Robinson, and Miller formulas. These equations determine a healthy weight range based primarily on your gender and height, providing a target weight that supports overall health.
What is the ideal weight for my height?
The ideal weight for your height is typically determined by your Body Mass Index (BMI). For most adults, a healthy weight is one that maintains a BMI between 18.5 and 24.9. For example, a person who is 5'10" (178 cm) has an ideal weight range of 129 to 174 lbs.
Why does ideal weight differ between men and women?
Ideal weight differs between men and women because men generally have higher bone density and muscle mass, while women naturally have a higher percentage of body fat. The formulas use separate constants for men and women, derived from historical height–weight data.
Does age affect ideal weight calculations?
While standard IBW formulas focus on height, medical experts note that a 'healthy' weight may shift slightly with age, as older adults may benefit from higher lean mass for longevity.

Calculations use published formulas and the standard adult BMI categories. They do not replace medical advice.
