Estimating Your Ideal Body Weight
Overview
Ideal body weight formulas estimate a healthy weight range based on your height and sex, giving a reference point for fitness and health goals. This calculator applies established formulas instantly in your browser. It is a general guide, not medical advice.
How to Use (Step by Step)
- 1
Enter your height
Use centimeters or feet and inches.
- 2
Select your sex
Formulas adjust the target slightly by sex.
- 3
Read the range
Compare your current weight to the estimated ideal range.
How It Works
The tool uses classic equations — such as Devine, Robinson, and Hamwi — that derive a target weight from height, with an adjustment for sex. These formulas were developed for clinical dosing and give a reasonable healthy-weight reference, though they do not account for muscle mass, frame size, or body composition. Comparing your weight to the range is more useful than fixating on a single number.
When to Use This
Setting a realistic weight goal. Getting a reference range for a fitness plan. Comparing several formula results to understand a healthy band rather than one figure.
Frequently Asked Questions
Not exactly. These formulas give a reference point but ignore muscle, frame, and body composition. A range, plus measures like body fat, gives a fuller picture.
