The Ideal Weight Calculator gives you a healthy weight range based on your height, age and gender using four established medical formulas: Hamwi, Devine, Robinson and Miller. No single formula is perfect — the range gives you a realistic target.
Frequently Asked Questions
How is ideal weight calculated?
This calculator uses four formulas simultaneously: Hamwi (1964), Devine (1974), Robinson (1983) and Miller (1983). Each gives a slightly different result — the average is your best target.
Is ideal weight the same for everyone of the same height?
No — body frame size, muscle mass, age and gender all affect what a healthy weight looks like for a given height.
What if I am above my ideal weight range?
Ideal weight ranges are guidelines, not strict targets. Focus on healthy habits rather than a specific number. Consult a doctor for personalised advice.
How accurate are ideal weight formulas?
They are useful starting points but were developed on limited populations. Use them alongside BMI and body fat percentage for a fuller picture.
