Ideal Weight for Height Calculator
Find a healthy target weight for your height. This calculator uses the Devine formula and also shows your healthy BMI-based weight range, so you get a realistic window rather than one number.

Enter the requested values using consistent units. Change one input at a time when comparing scenarios, and verify every value before using the result.
The estimate uses the values currently entered and the formula described on this page. Any fees, taxes, timing rules or personal circumstances not requested are excluded.
This tool provides formula-based reference weights and a BMI-derived range for adults.
The healthy-range calculation applies adult BMI values of 18.5 to 24.9 to height: weight = BMI × height². Other named formulas provide reference points, not medical targets.
At 1.75 m, the BMI-derived reference range is approximately 56.7 to 76.3 kg.
The range is broader and more useful than treating one formula result as a perfect weight.
Body frame, muscle mass, age, pregnancy and health conditions are not fully represented. The output is not a diagnosis or personal treatment goal.
