About the Weight Calculator
This weight calculator shows the healthy weight range for your height, based on the standard healthy BMI band (18.5 to 24.9). It is a quick reference for understanding a reasonable target range rather than a single "ideal" number, since healthy bodies come in a range of weights.
How it works
A healthy weight range is calculated as BMI × height² across the healthy band: the lower bound uses BMI 18.5 and the upper bound uses BMI 24.9, with height in metres. Enter an optional current weight to see where you fall on the scale.
Reading the chart
The band chart shows the under, healthy, over, and obese weight ranges for your height, with a marker at your current weight if you enter one.

FAQ
Is BMI a perfect measure?
No. BMI does not distinguish muscle from fat, so very muscular people may read as "overweight" despite low body fat. Use it as one general indicator, not a verdict.
Why a range instead of one number?
Because healthy weight depends on build, muscle mass, and body composition. A range acknowledges that several weights can be perfectly healthy for one height.
What should I do with this?
Treat it as context. For personalized goals, a doctor or dietitian can account for your body composition, health history, and lifestyle.
