⚖️ Ideal Weight Calculator

Our Ideal Weight Calculator uses four medically recognized formulas — Devine, Robinson, Miller, and Hamwi — to estimate your healthy weight range based on gender, height, age, and body frame size.

Simply enter your details: select male or female, input height in centimeters, provide your age, and choose small, medium, or large body frame. Get instant results calculated using all four methods side by side.

The Devine formula (1974) is widely used in clinical settings for medication dosing. Robinson (1983) and Miller (1983) offer refined adjustments, while Hamwi (1964) uniquely considers body frame size for personalized estimation.

Knowing your ideal weight helps set realistic fitness goals, monitor health risks, and maintain a balanced lifestyle. It serves as a guide — not an absolute target — for better well-being.

This free online calculator lets you compare results across established formulas. Ideal weight varies by individual; consult a healthcare professional for a comprehensive health assessment.
