Formulas Used

These formulas were developed as height-based reference weight equations. They use a base weight at 5 feet and add weight for each inch above 5 feet.

Devine
Male: 50 kg + 2.3 kg per inch over 5 ft
Female: 45.5 kg + 2.3 kg per inch over 5 ft
Robinson
Male: 52 kg + 1.9 kg per inch over 5 ft
Female: 49 kg + 1.7 kg per inch over 5 ft
Miller
Male: 56.2 kg + 1.41 kg per inch over 5 ft
Female: 53.1 kg + 1.36 kg per inch over 5 ft
Hamwi
Male: 48 kg + 2.7 kg per inch over 5 ft
Female: 45.5 kg + 2.2 kg per inch over 5 ft
Important: There is no single ideal body weight that applies to everyone. These formulas provide rough adult reference estimates and do not account for body composition, muscle mass, frame size, pregnancy, health conditions or individual differences. The BMI-based range is also a screening reference rather than a personal medical target.

Ideal Weight Calculator

Vedicaly's Ideal Weight Calculator provides an estimate of ideal body weight based on information such as height and sex. It uses established mathematical formulas to provide reference weight estimates.

How to Use the Ideal Weight Calculator

Enter the requested information, including your height and other available details. The calculator will calculate an estimated ideal weight based on the formulas used by the tool.

What Is Ideal Body Weight?

Ideal body weight is a calculated reference value rather than a single medically correct weight for every person. Different formulas can produce different results because they use different mathematical approaches.

What Can Affect a Healthy Weight?

A suitable body weight can vary according to factors such as height, age, body composition, muscle mass and individual circumstances. A calculated ideal weight should therefore be treated as a general reference rather than an exact target.

Why can ideal weight formulas give different results?

Ideal weight formulas were developed using different methods and assumptions. As a result, the estimated weight can vary depending on which formula is used.

Is ideal weight the same as BMI?

No. Ideal weight formulas estimate a reference body weight, while BMI relates a person's weight to their height. Both are general screening or reference tools and do not provide a complete assessment of an individual's health.
