Enter your height to see the adult BMI-based reference weight range (BMI 18.5–24.9) in kilograms and pounds.
Your height is processed only in your browser. Nothing is uploaded to our servers, saved in cookies, or sent to analytics.
Adult heights between 50 and 250 cm (about 20 to 98 in) are accepted.
The adult BMI healthy range is 18.5 to 24.9 kg/m². The lower and upper reference weights are that interval multiplied by your height in metres squared. Imperial inputs are converted with exact factors (1 in = 2.54 cm; 1 lb = 0.45359237 kg), so results differ from calculators that use the rounded '703' shortcut.
BMI is a screening measure, not a diagnosis. It does not directly measure body fat and can misclassify muscular, older, pregnant, or ethnically diverse individuals. Standard adult BMI ranges must not be applied to children, teenagers, or pregnancy — those use age- and sex-specific charts assessed by clinicians.
lower weight = 18.5 × height² (m) upper weight = 24.9 × height² (m)
It multiplies your height in metres squared by the healthy adult BMI boundaries: 18.5 for the lower bound and 24.9 for the upper bound.
No. It is an adult BMI-based reference range. A personalized healthy weight considers muscle mass, bone density, fat distribution, and health history.
No. Adult BMI ranges do not apply to children, teenagers, or pregnancy. Growth and pregnancy use specialized charts that clinicians assess.
The BMI Calculator computes your BMI from height and weight and shows the category. This tool does the reverse direction: it gives the weight range that corresponds to the healthy BMI band for your height.
This calculator provides a general adult screening reference for educational purposes, not medical advice or a diagnosis. Weight and BMI have real limitations as health measures. Discuss weight, nutrition, and body composition goals with a healthcare professional — especially during pregnancy, in childhood, or when managing a health condition.
