BMI Calculator Online Calculate your BMI Online


Age can be taken into account when calculating the Body Mass Index (BMI) and accompanying weight status using the BMI Calculator. To convert units into US or metric units, use the “Metric Units” page for the International System of Units or the “Other Units” option. Keep in mind that the calculator not only calculates BMI but also the Ponderal Index; they are covered in depth below.


You can compute and assess your Body Mass Index (BMI) with this ad-free BMI calculator by entering pertinent data about your height, age, sex, and body weight. Determine your target weight by looking at your body metrics. Being overweight or obese increases your chance of developing conditions including diabetes, heart disease, and hypertension. If you’re on a diet or wish to reduce weight, you can also use it to determine your healthy weight. The World Health Organization’s (WHO) website has more details regarding the BMI classification that the BMI Calculator uses.


BMI introduction

Based on a person’s height and weight, BMI calculates their leanness or corpulence and is used to determine tissue mass. It’s commonly used to determine whether an individual is at a healthy body weight for their height. To be more precise, the BMI value is used to determine a person’s classification as underweight, normal weight, overweight, or obese based on where the value falls in the range. These BMI ranges are subject to regional and age-based variations, and they are occasionally further classified into extremely underweight and extremely obese subcategories.

Although BMI is not a perfect estimate of healthy body weight, it can be a helpful tool in determining whether further testing or treatment is necessary because being overweight or underweight can have serious health consequences. View the table below to view the many BMI-based categories that the calculator uses.

What is BMI?

You can use your body mass index, or BMI, to find out if your weight is within the recommended range for your height.

It helps you determine if you are “underweight,” “overweight,” “obese,” or at a “healthy weight” in relation to your height. One type of instrument that health practitioners might use to determine a patient’s risk for chronic disease is BMI.

For the majority of adults over 20, BMI is a meaningful measurement. Given that it is an estimate and does not account for factors like age, gender, race, or body composition, it should only be used as a general reference.
