BMI Calculator

About BMI Calculator

Body Mass Index is one of the most widely used screening tools in healthcare. While it doesn't directly measure body fat, it provides a quick population-level indicator of whether someone falls within a healthy weight range for their height. Davirix BMI Calculator computes your score using the standard formula (weight in kg divided by height in meters squared) and places you on a color-coded chart spanning underweight, normal, overweight, and obese categories. The tool accepts both metric and imperial units, shows the healthy weight range for your height, and includes context about what BMI does and doesn't tell you.

Frequently Asked Questions

What is a healthy BMI?

The WHO considers 18.5–24.9 a normal BMI range. Below 18.5 is underweight; 25–29.9 is overweight; 30+ is obese. These are population-level guidelines, not individual diagnoses.

Is BMI accurate for everyone?

BMI doesn't distinguish between muscle and fat. Athletes with high muscle mass may show an elevated BMI despite low body fat. It's a screening tool, not a diagnostic one.

Does it work for children?

This calculator uses the adult BMI formula. Pediatric BMI uses age-and-sex-specific percentile charts — consult your child's healthcare provider.
