Q: Which ideal weight formula is most accurate?
A: Each formula has different strengths. Devine is widely used in medical settings, Hamwi is simpler, Robinson adjusts for height, and Miller provides a slightly higher estimate. The average of all four is often the most balanced.
Q: What is a healthy BMI range?
A: A BMI between 18.5 and 24.9 is considered healthy for most adults. The calculator shows the healthy weight range corresponding to these BMI values for your height.
Q: Why are the results from different formulas different?
A: Each formula was developed using different populations and methodologies. Devine (1974) was designed for medical dosing, while Hamwi (1964) is a simpler rule. The variations reflect different approaches to defining 'ideal' weight.
