BMI Calculator

The Body Mass Index Calculator (BMI calculator) is an essential tool that helps you measure the body weight. With the calculator, you can ensure that you have a healthy weight, This minimizes the risks of developing weight-related diseases, such as high blood pressure, type 2 diabetes, heart conditions, and more.



How it works?

    BMI is a measurement unit that determines whether you are obese, overweight, normal-weight, or underweight for your height. BMI quantifies your tissue mass to determine if you belong to the healthy-weight range. Apart from the height, BMI also depends on your age and gender. You can use an online BMI calculator to get a better idea.

    The Centers for Disease Control and Prevention (CDC) recognizes people aged between 2 to 20 as kids and teens. Below is the BMI chart for this age category.

    • Underweight: Below 5th percentile

    • Healthy weight: 5% - less than the 85th percentile

    • At risk of overweight: 85th - less than the 95th percentile

    • Overweight: Over 95th percentile

    According to the World Health Organization (WHO), people aged 18 or over can use the body mass index calculator for adults to determine whether they have a healthy weight. Here is the adult BMI chart:

    • Normal weight: 18.5 – 24.9

    • Overweight: 25 – 29.9

    • Class I obese: 30 - 35

    • Class II obese: 35 - 40

    • Class III obese: Over 40

    To get an accurate BMI on the calculator, follow the below steps:

    1. Decide if you need an online BMI calculator in kg and feet or any other unit and use the appropriate system accordingly

    2. Input your current age

    3. Select your gender

    A body mass index calculator offers you an accurate BMI, but the indicator does have certain shortcomings, too. Humans have diverse body types, depending on factors like bone mass, muscle distribution, body fat, ethnicity, and more. The calculator does not take these into account, resulting in a less-than-accurate result from the BMI test online. Therefore, other tools like Blood Sugar Level Calculator come in handy for assessing different parameters and give you another perspective.
