What is BMI and how is it calculated?

BMI (Body Mass Index) is calculated by dividing your weight in kilograms by your height in meters squared. The formula is: BMI = weight (kg) ÷ height (m)². Our interactive calculator does this automatically.

What are the BMI categories?

BMI categories are: Underweight (< 18.5), Normal weight (18.5-24.9), Overweight (25-29.9), and Obese (≥ 30). These categories help assess health risks associated with weight.

Is BMI accurate for everyone?

BMI is a useful screening tool but has limitations. It doesn't distinguish between muscle and fat, so athletes may have higher BMI due to muscle mass. It may also be less accurate for older adults, pregnant women, and certain populations.

How do I use the BMI calculator?

Simply enter your height and weight using the sliders. The calculator will instantly show your BMI, category, and ideal weight range. You can adjust the weight slider to visualize how different weights affect your BMI.

What is a healthy BMI range?

A healthy BMI range is typically 18.5 to 24.9. This range is associated with lower health risks. However, individual factors like age, muscle mass, and medical conditions should be considered.
