About Ideal Weight Calculator

The ideal weight calculator uses established formulas — including the Hamwi, Devine, and Robinson methods — to estimate a healthy target weight range based on your height and gender. Because no single number is right for every person, the calculator presents a range that accounts for natural variation in body frame and muscle mass. Use it as a general health guideline, not a rigid target.

Frequently Asked Questions

Which ideal weight formula is most accurate?

No single formula is universally best. The Devine formula is widely used in clinical settings, while the Hamwi method is popular for nutritional assessments. This calculator shows results from multiple methods so you can see the consensus range rather than relying on one figure.

Should I aim for the exact ideal weight number?

Not necessarily. Ideal weight formulas don't account for muscle mass, bone density, or body composition. A person with significant muscle may weigh more than the 'ideal' while being extremely healthy. Use the range as a general guide, and prioritize body fat percentage and how you feel over a specific number.

How is ideal weight different from BMI?

BMI uses your current weight relative to height to classify you as underweight, normal, overweight, or obese. Ideal weight calculators instead estimate what you should weigh given your height, giving you a goal to aim for rather than a classification of where you currently stand.
