Results are estimates based on height and sex only. Body composition, muscle mass, and individual variation are not accounted for.

Ideal Body Weight (IBW) is a clinical estimate of a healthy weight range for a given height and sex. It was originally developed for medical dosing and clinical purposes, not aesthetics. The result gives you a reference point — not a target — for understanding where your weight sits relative to your height.

How to Use This Calculator

Select your sex (male or female) — each formula uses sex-specific constants.

Enter your height in centimeters.

The calculator instantly shows results for all four formulas and their average.

Use the average as your reference point — individual formulas can vary by 5–10 kg.

How Ideal Body Weight Formulas Work

All four formulas share the same structure: a base weight (at 5 feet / 152 cm) plus an increment for each additional inch of height. They were developed in clinical settings between 1964 and 1983, originally to estimate proper drug dosages.

Because they only account for height and sex — not muscle mass, bone density, or body composition — they are best used as a rough reference rather than a precise target.

The Four Formulas

Devine (1974): Men = 50 + 2.3 × (height_in − 60) | Women = 45.5 + 2.3 × (height_in − 60)

Miller (1983): Men = 56.2 + 1.41 × (height_in − 60) | Women = 53.1 + 1.36 × (height_in − 60)

Robinson (1983): Men = 52 + 1.9 × (height_in − 60) | Women = 49 + 1.7 × (height_in − 60)

Hamwi (1964): Men = 48 + 2.7 × (height_in − 60) | Women = 45.5 + 2.2 × (height_in − 60)

Why Formulas Differ

Each formula was built from a different patient population at a different time. Devine was originally used for medication dosing in obese patients. Miller and Robinson were designed to represent typical healthy adults. Hamwi is the oldest and uses the most aggressive increment per inch.

The spread between them gives you a realistic range — typically 3–8 kg — that represents the uncertainty in any height-only estimate.

IBW vs BMI vs Body Fat

IBW gives you a single number based on height and sex. BMI also uses weight in the calculation, placing you on a spectrum from underweight to obese. Body fat percentage is the most accurate measure of body composition because it distinguishes muscle from fat.

For most people, IBW is a useful starting point — but body fat percentage tells a more complete story, especially for athletes and strength-trained individuals.

Ideal Body Weight for Personal Trainers

As a personal trainer, IBW calculators are useful for initial client assessments. They give you a quick, defensible reference point when discussing weight goals — and the multi-formula view helps you explain why a single number is never the whole picture.

With Gymkee, you can record and track client assessment data over time, including weight, body measurements, and fitness test results, giving you a complete picture of progress beyond any single metric.
