Ideal Weight Calculator
Compare your ideal body weight across four clinical equations (Devine, Robinson, Miller, Hamwi) and the Asian-Indian healthy BMI window.
Informational health estimates only
Outputs from this utility are based on population-level peer-reviewed formulas (WHO, Mifflin-St Jeor, US Navy, Devine) and are intended for educational wellness screening—not medical diagnosis or clinical treatment.

How the Ideal Weight Calculator works
Compare your ideal body weight across four clinical equations (Devine, Robinson, Miller, Hamwi) and the Asian-Indian healthy BMI window. Below is the exact mathematical or algorithmic model used by this body metrics utility, along with its key operating assumptions.
Devine (Male) = 50 kg + 2.3 kg × ( inches over 5 feet ); Female = 45.5 kg + 2.3 kg × ( inches over 5 feet ).Step-by-step workflow
- Select your clinical reference standard or biological sex and enter height, weight, or activity metrics in the Ideal Weight Calculator.
- The physiological model computes Devine (Male) = 50 kg + 2.3 kg × ( inches over 5 feet ); Female = 45.5 kg + 2.3 kg × ( inches over 5 feet ). and maps your score against established reference bands.
- Use the target range and daily macro/hydration breakdown as an educational baseline alongside professional medical guidance.
Worked example & key advantages
For a 173 cm (5 ft 8 in) male, the Devine formula estimates 68.7 kg inside an Asian-Indian normal BMI range of 55.4–68.5 kg.
Why use this Ideal Weight tool
- Includes both Asian-Indian (ICMR) and WHO global BMI cutoffs alongside Mifflin-St Jeor and US Navy equations.
- Translates raw metabolic numbers into actionable daily calorie, protein-per-meal, and hydration targets.
- Runs privately in your browser with no account sign-up or health-data tracking.
Important Assumptions & Scope
- Clinical formulas are height-based reference points and do not account for heavy skeletal muscle mass.

The Devine formula (1974) is the most widely used clinical reference for height-based weight estimation.
Are results from the Ideal Weight Calculator a substitute for medical advice?
No. The Ideal Weight Calculator implements peer-reviewed population equations for general wellness education and fitness screening. Always consult a physician or registered dietitian for clinical guidance.
How often should I recalculate my metrics in the Ideal Weight?
Recalculating every 4 to 8 weeks—or whenever your body weight, training volume, or lifestyle activity level changes significantly—helps keep your nutrition and wellness targets aligned.
