BMI calculator FAQs
These BMI calculator FAQs explain the common reference ranges and why BMI should be treated as a screening tool.
What BMI range is considered normal?
For adults, a BMI from 18.5 to 24.9 is commonly considered the standard reference range.
Does BMI measure body fat directly?
No. BMI is a screening formula based on height and weight, so it cannot distinguish muscle from fat.
Is BMI useful for athletes?
It can be a rough reference, but athletes often have more muscle mass, so BMI may overstate body fat risk.
