This calculator finds the weight range that corresponds to a BMI between 18.5 and 25, the range widely classified as 'normal weight'. It rearranges the BMI formula (BMI = weight ÷ height²) to solve for weight at each end of that range, using your height in meters squared.
For example, at a height of 175 cm (1.75 m): the minimum healthy weight is 18.5 × 1.75² = 18.5 × 3.0625 ≈ 56.7 kg, and the maximum is 25 × 3.0625 ≈ 76.6 kg, giving a healthy weight range of roughly 56.7 to 76.6 kg (about 124.9 to 168.8 lb).
The Ideal Weight Calculator uses the Devine formula to give a single point estimate based on height and gender. This calculator instead gives a full range based on the standard BMI classification, which doesn't factor in gender at all, since BMI ranges are defined the same way for men and women.
Treating the top or bottom of the range as a strict personal target, the whole range is considered healthy for most people, there's no requirement to sit at any particular point within it.
Ignoring that this range doesn't account for muscle mass, a muscular individual can weigh above this range while still being healthy, since BMI-based ranges don't distinguish muscle from fat.
Using this range for children or teenagers, it's based on the adult BMI classification and doesn't apply to growing bodies, which need age- and sex-specific growth charts instead.
The standard BMI healthy-weight range (18.5-25) is defined the same way regardless of gender, so gender isn't a factor in this particular calculation.
No, BMI doesn't distinguish between muscle and fat mass, so athletes and very muscular individuals may fall outside this range while still being healthy. Use this as a general reference, not a definitive assessment.
The Ideal Weight Calculator gives one specific target weight using the Devine formula. This calculator gives a broader healthy range based on standard BMI classification instead.
