Measure consistently
Measure standing height without shoes. If including current weight, use consistent equipment and conditions for trend comparisons.
Adult BMI-derived weight interval
Adult Weight Range by BMI
Calculate the weight interval corresponding to adult BMI 18.5–24.9, show every category boundary at the entered height, and add current weight only as neutral screening context.

Method and interpretation guide
Use the adult weight range result as a transparent estimate
Measure standing height without shoes. If including current weight, use consistent equipment and conditions for trend comparisons. The worksheet exposes its assumptions so the result can be checked instead of accepted as a black box.
Read the assumptions
The interval comes only from BMI 18.5–24.9. BMI is a screening measure and cannot determine a personal goal or diagnose health.
Escalate important decisions
A calculator cannot examine symptoms, medical history, medication effects or measurement quality. Use qualified professional guidance when the decision has health consequences.

False precision
Extra decimal places do not remove biological variation, input error or limits in the underlying population equation.
Scope
