BMI Calculator — Overview

The Body Mass Index (BMI) is a measure that uses your height and weight to work out if your weight is healthy. The BMI calculation divides an adult's weight in kilograms by their height in metres squared.

How is it calculated?

The formula for BMI is weight in kilograms divided by height in meters squared (kg/m²). A BMI between 18.5 and 24.9 is considered healthy. Below 18.5 is underweight, 25 to 29.9 is overweight, and 30 or above is obesity.

Frequently Asked Questions

BMI is a good general indicator for most adults. However, it's not a diagnostic tool. It can be less accurate for athletes or bodybuilders, as muscle is denser than fat. It also doesn't consider factors like body composition, age, or gender in its formula.

To lower a high BMI, focus on a balanced diet with a calorie deficit and regular physical activity, including both cardio and strength training. To increase a low BMI, focus on a calorie surplus with nutrient-dense foods and strength training to build muscle mass. Always consult a professional before making drastic changes.

The most important metric is your pre-pregnancy BMI, which helps your doctor recommend a healthy weight gain range. BMI is NOT tracked during pregnancy because the number becomes misleading as it doesn't account for the weight of the baby, placenta, or increased fluids. Instead, doctors monitor total weight gain.
