What the healthy weight range calculator does
Rather than a single "ideal" number, this calculator shows the full span of weights considered healthy for your height, based on the World Health Organization's BMI guidelines. It returns the range in both kilograms and pounds, plus a midpoint you can use as a reference target.
How the calculation works
A healthy BMI is defined as 18.5 to 24.9. The tool multiplies each of those BMI values by the square of your height in metres to produce the lower and upper healthy weights. If you enter imperial units, your height is converted to centimetres first, so the result is consistent.
How to interpret your result
Anywhere within this range is generally associated with lower health risk for most adults. Where you sit within it can reflect frame size, muscle mass, and personal preference. Because BMI does not measure body fat directly, a muscular individual may weigh above the range while remaining lean and healthy.
Health recommendations
If your weight falls outside the range, gradual changes to nutrition and activity are safer and more durable than rapid swings. Use this alongside the BMI, Body Fat, and Ideal Weight calculators, and consult a healthcare professional for personalised advice.
