Ideal Weight Calculator: compare Robinson, Miller, Devine, Hamwi, and healthy BMI range estimates from height, age, and gender.
Ideal Weight
The Ideal Weight Calculator estimates ideal body weight based on height and gender. It compares several well-known formulas, including Robinson, Miller, Devine, and Hamwi, and also shows the healthy weight range based on BMI.
Ideal body weight formulas are general references. They do not account for body composition, muscle mass, medical conditions, or individual health goals. Use the result as a guideline, not as a strict target.
Weight Formulas
Hamwi Formula, Devine Formula, Robinson Formula, and Miller Formula are classic adult ideal body weight equations. They give a quick comparison point, but they are not a substitute for clinical assessment.
Healthy BMI Range
The healthy BMI range used here is 18.5 to 25. The corresponding weight range depends on height, so taller people naturally have a higher healthy weight range than shorter people.
Limitations
Ideal weight formulas are designed for broad estimation and may not be accurate for athletes, children, teenagers, pregnant people, elderly people, or people with specific medical conditions.
Disclaimer: This calculator provides general estimates of ideal body weight based on standard formulas. Results may vary and do not consider individual factors such as body composition or health condition. The values should be used as guidelines only and not as medical advice. Consult a healthcare professional for personalized recommendations.
Ideal Weight Calculator FAQ
What is ideal body weight?
Ideal body weight is a formula-based estimate of the weight range commonly associated with a given height and gender.
Which ideal weight formula is best?
There is no single best formula for everyone. Robinson, Miller, Devine, and Hamwi are all widely used reference formulas, so this calculator shows them side by side.
Why does the calculator show a healthy BMI range too?
The healthy BMI range gives a height-based range from BMI 18.5 to 25. It is useful as a second reference next to the older ideal weight formulas.
Can children and teenagers use this calculator?
Not as a clinical target. Adult ideal body weight formulas are not suitable for children or teenagers. For under-18s, healthy weight is usually assessed with age- and sex-specific BMI percentiles.
Why are the formulas only estimates?
They do not account for muscle mass, body composition, medical conditions, pregnancy, athletic build, or individual goals. They are best used as general reference values.
