BMI Calculator for Women and Men – Body Mass Index Checker

Whenever you hear someone talk about health, weight and fitness, you often hear the word ‘BMI’. And you are left wondering what BMI is, how it affects your body and how you can make sure your BMI is as per charts and well within your healthy weight range.

In this article, we will explain what BMI is, how to calculate BMI, what should your ideal BMI be and some tips on how to lose weight and stay healthy.

What is BMI?

BMI means Body Mass Index. In simple words, BMI is used to determine whether your weight is proportionate to your height and whether you are in the healthy weight range compared to many factors such as your age, height, etc.

How to calculate BMI?

What BMI does is that it compares your body weight with your height. To calculate your body’s BMI, you divide the weight of your body in kilograms with your height (measured in meters square). You then compare the end figure with a set range to understand whether you are underweight, overweight, obese or healthy for an individual of your height.

As a measure, BMI is intended for use by adults only and not by adolescents and children. This is because children and adolescents are growing and calculating BMIs for them is not a true representation of their health as their height constantly grows. For adults, because they have stopped growing, BMI increases when the fat component in the body increases.

Here is an indication of BMIs for you to understand which category you can fall under after you calculate your individual BMIs.

  • BMI of 18.5 kilogram per meter square or under: you are underweight and most probably malnourished
  • BMI between 18.5 kilogram per meter square and 24.9 kilogram per meter square: you come under the healthy weight range of a young adult and middle-aged being
  • BMI between 25 kilogram per meter square and 29.9 kilogram per meter square: you are overweight
  • BMI of over 30 kilogram per meter square: you are obese

Weight loss and calories

Now that you have calculated your BMI, if your result says you are overweight or obese, the next thing you should start considering is calories and how many calories does your body need to start losing weight in a healthy manner.

On an average, a woman in the age group of 30 to 40 years old need about 2000 calories in one day to maintain weight and shed off any excess fat from the body. On the other hand, a man in the age group of 30 to 40 years old, needs about 2500 calories in one day to maintain a healthy weight and height ratio and get rid of any excess fat stored in the layers of the skin over time.

Calorie intake also depends on a number of factors such as the following:

  • Your age
  • Your height
  • Your current weight
  • Your desired weight
  • Your activity level
  • Your metabolic health
  • And many other medical factors


Now that you understand what BMI is and how to calculate your BMI, you can start your journey to a healthy life and take the necessary steps that will help you achieve a healthy weight and height balance that can stay with you in the long run.
