BMI reference weight range

Mathematical weight interval for adult BMI 18.5 to below 25; not an ideal weight.

Calculated result

Lower adult BMI reference boundary; not an ideal weight or a diagnosis.

Upper BMI reference boundary (25 excluded): 81 kg

Results are estimates or simple arithmetic, not medical or investment advice.

How it works

See the approximate weight equivalents of the adult BMI 18.5 to below 25 reference interval for your height. This is not an ideal-weight recommendation.

Method and limitations

Square height in meters and multiply by the BMI boundaries. Body composition and personal medical history are not considered.

Lower boundary = 18.5 × height(m)²; upper boundary (excluded) = 25 × height(m)².

Frequently asked questions

Why exclude the upper boundary?

Adult BMI reference classification includes 18.5 but excludes 25.

Is this a weight target?

No. It is simply the mathematical height-based equivalent of BMI reference thresholds.
