How to calculate
Estimate the weight range corresponding to a chosen BMI range.
Lower weight = low*height^2; Upper weight = high*height^2
Worked example
Height (m): 1.75; Lower BMI: 18.5; Upper BMI: 24.9.
Lower weight: 56.66 kg; Upper weight: 76.26 kg.
Assumptions and limits
BMI ranges are screening conventions and do not measure body composition or define an individual ideal weight.
Results are rounded for display; calculations use unrounded values. Read our calculation methodology.
Understanding the result
Estimate the weight range corresponding to a chosen BMI range. The displayed figures use the inputs and formula shown on this page.
When this tool is useful
Use the ideal weight range to compare a scenario, check an estimate, or verify a manual calculation.
