Ideal Weight Calculator
Find your ideal body weight range using multiple established formulas.
Ideal weight estimates are screening references, not medical targets.
Ideal weight calculator
Enter your height and sex estimate to compare common reference formulas.
Estimated reference weight range
65.2 kg–66.9 kg
Based on Devine, Robinson, Miller, and Hamwi formula estimates.
Midpoint estimate
66.0 kg
Average of formula-specific estimates.
BMI healthy reference range
53.5 kg–72.0 kg
Approximate BMI 18.5–24.9 range.
Uses standard ideal weight reference formulas. Reviewed for accuracy. Estimate only. Does not replace medical, dietetic, or professional health advice.
Personalized interpretation
For your height, common formulas estimate a reference weight range around 65.2 kg–66.9 kg.
Different formulas may produce different estimates because they use different assumptions.
A healthy weight is influenced by muscle mass, body composition, age, ethnicity, medications, pregnancy, health history, and personal goals.
This result should not be treated as a required target. If you have concerns about weight or health, consider speaking with a qualified healthcare professional.
Healthy weight range guide
Formula range
65.2 kg–66.9 kg
Range from common ideal body weight formulas.
Midpoint
66.0 kg
A simple average, not a required target.
BMI reference
53.5 kg–72.0 kg
Broader BMI-based screening range.
What ideal weight means
Ideal weight vs BMI vs body composition
Ideal weight
Estimates reference weight from height and sex.
BMI
Compares weight to height but does not directly measure body composition.
Body composition
Estimates fat mass versus lean mass and can add useful context.
Formula methods compared
Devine
Commonly used reference formula based on height over 5 feet.
Robinson
A height-based formula with slightly different sex-specific assumptions.
Miller
Another reference formula that often gives a different estimate.
Hamwi
Often referenced in dietetic settings and based on pounds over 5 feet.
BMI healthy range
A broader screening reference based on BMI 18.5–24.9.
Why results vary between formulas
Variation between formulas is normal. A range is usually more useful than one number.
Limitations and healthy context
Ideal weight calculators are not a diagnosis, not a treatment plan, and should not replace professional medical advice.
Formula explanation
Devine: Men = 50 kg + 2.3 kg/in over 5 ft; Women = 45.5 kg + 2.3 kg/in over 5 ftRobinson: Men = 52 kg + 1.9 kg/in; Women = 49 kg + 1.7 kg/inMiller: Men = 56.2 kg + 1.41 kg/in; Women = 53.1 kg + 1.36 kg/inHamwi: Men = 106 lb + 6 lb/in; Women = 100 lb + 5 lb/inBMI healthy range: Healthy Weight = BMI × height²Example: 5 ft 10 in
Common formulas often estimate a broad reference range, while BMI gives a wider screening range for the same height.
Example: 170 cm
With the current calculator defaults, the formula reference range is 65.2 kg–66.9 kg.
