Frequently Asked Questions
Is a BMI of 18.2 considered healthy?
For adults, BMI categories are standardized. Your result falls in the underweight range. Use this as a screening signal, then pair it with waist and body-fat metrics for better individual context.
What weight range usually maps to a "normal" BMI at 68"?
At 68" (about 173 cm), the normal-BMI band is roughly 122-164 lb.
Should I use BMI alone to make decisions?
BMI is helpful for broad risk stratification, but it does not separate fat from muscle. Combine it with body-fat percentage, waist measurements, and trend data over time.
