General estimate
Reference Weight Range
Shows a broad BMI-based reference range, not a personal ideal.
How this estimate is calculated
The weight range that corresponds to a BMI of 18.5 to 24.9 at your height.
How to use the result
Treat it as a starting point to compare against how you actually feel and what you actually eat. Estimates are most useful for spotting a large gap, not for chasing a precise number.
What this cannot tell you
This is a statistical reference band, not a personal ideal. A healthy weight for you depends on body composition, history and health, and is a conversation with a clinician.
Estimates, not measurements: this tool runs a population equation, so it describes a typical person with your inputs rather than measuring you. Where a number drives a decision about a diagnosed condition or medication, have a dietitian or clinician sanity-check it against your history.
