BMI stands for Body Mass Index. It’s a measure that uses your height and weight to work out if your weight is healthy. It provides a quick way to categorize individuals into underweight, normal, overweight, or obese ranges.

How is BMI calculated? ▼

BMI is calculated by dividing your weight in kilograms by the square of your height in meters (kg/m²). Our calculator does this for you automatically when you input your measurements.

Is BMI accurate for everyone? ▼

While BMI is a widely used and useful screening tool, it may not be accurate for everyone. For example, it might overestimate body fat in athletes with high muscle mass or underestimate it in older people who have lost muscle mass.

What are the BMI classifications? ▼

Generally, the classifications are: Underweight (BMI less than 18.5), Normal weight (BMI 18.5-24.9), Overweight (BMI 25-29.9), and Obese (BMI 30 or greater).
