BMI Calculator
Estimate your adult body mass index from height and weight, then read the number with the context it deserves.
Your Body Stats
Adjust height and weight to estimate your adult BMI.
Estimated BMI
Your BMI sits in the standard adult healthy-weight range.
For adults 20+. BMI is a screening tool and does not diagnose health.
BMI CONTEXT
Read your number with care
A useful calculator should give you direction without pretending one number explains your whole health.
Screening, not diagnosis
BMI is a quick screening number. It does not measure body fat directly or diagnose health.
Measure carefully
A small height or weight error can shift the result, so use recent measurements.
Watch the trend
A steady trend often tells a better story than a single weigh-in.
Add health context
Blood pressure, labs, waist size, sleep, and activity can change what the number means.
Use gentle targets
If weight change is the goal, small consistent shifts are easier to maintain.
Adults only
Children and teens need age- and sex-specific BMI percentiles, not this adult calculator.
