What Is Ideal Body Weight?

Ideal Body Weight (IBW) is a clinical baseline calculated using height, gender, and validated medical formulas (Devine & Robinson).

Frequently Asked Questions

What is the Devine formula for ideal body weight?

The Devine formula calculates ideal weight based on height: Men = 50 kg + 2.3 kg per inch over 5 feet; Women = 45.5 kg + 2.3 kg per inch over 5 feet.

How does frame size affect ideal weight?

Larger skeletal frame sizes add roughly 10% to ideal body weight estimates, while smaller frames subtract 10%.

Is ideal body weight the same as healthy BMI weight?

Ideal weight formulas estimate aesthetic or clinical baselines, whereas healthy BMI weight spans a range corresponding to BMI 18.5–24.9.

Does muscle mass change ideal weight?

Yes. Athletes with high muscle mass may weigh more than standard ideal weight formulas suggest while maintaining low body fat.
