BMI Calculator

Calculate your Body Mass Index and understand your weight category.

About BMI Calculator

Free BMI (Body Mass Index) calculator that determines your BMI category using your height and weight. Supports both metric (kg/cm) and imperial (lbs/ft-in) units. Displays your BMI score, weight category (underweight, normal, overweight, obese), and healthy weight range for your height. Includes a visual BMI scale chart for easy interpretation. Note: BMI is a screening tool and not a diagnostic measure.

Frequently Asked Questions

How is BMI calculated?
BMI is calculated by dividing your weight in kilograms by your height in meters squared (kg/m²). The tool handles the math automatically - just enter your height and weight in either metric or imperial units.
What are the BMI categories?
The standard WHO categories are: Underweight (below 18.5), Normal weight (18.5-24.9), Overweight (25-29.9), and Obese (30 and above). The tool displays your category and a visual scale.
Is BMI an accurate measure of health?
BMI is a useful screening tool but has limitations. It doesn't account for muscle mass, bone density, age, or body fat distribution. Athletes and muscular individuals may have a high BMI while being healthy. Consult a healthcare provider for a complete assessment.
What is a healthy BMI range?
A BMI between 18.5 and 24.9 is considered normal or healthy weight by the WHO. Within this range, you have the lowest statistical risk for weight-related health conditions. The tool also shows the healthy weight range in kilograms or pounds for your specific height.
Does BMI differ for men and women?
The standard BMI formula and categories are the same for both men and women. However, women naturally have more body fat than men at the same BMI. For a more gender-specific assessment, consider waist circumference or body fat percentage measurements alongside BMI.
