BMI Table For Children

For children and adolescents under the age of 18, the BMI is calculated in the same way as for adults, but the interpretation of the BMI result is different. For children and teens, their BMI is plotted on a growth chart that takes into account their age and sex, in addition to their BMI.


The result is then interpreted as a percentile ranking, which compares their BMI to that of other children of the same age and sex.

The following Percentile Range are Used to Categorize a Child or Adolescent's BMI: 


  • Underweight: <5%

  • Healthy Weight: 5% - 85%

  • At Risk of Overweight: 85% - 95%

  • Overweight: >95%

It's important to note that BMI is just one indicator of a child or adolescent's overall health, and should be used in combination with other measures such as physical activity, diet, and medical history.

What is your BMI?

Your body mass index (BMI) is a calculation that estimates your body weight in relation to your height. While it does not directly measure your body fat percentage, BMI is a useful tool to gauge a healthy body weight based on your height.


Its widespread use is due to its ease of calculation and measurement, making it the most commonly used diagnostic indicator to determine a person's optimal weight based on their height. Calculating your BMI can determine whether you are underweight, of normal weight, overweight, or obese.

However, it is important to note that BMI should not be the only factor used to diagnose weight-related health issues. This is because body types can vary widely, as can muscle and bone mass distribution. Therefore, BMI should be used in conjunction with other diagnostic indicators to gain a more accurate picture of an individual's health status.

BMI Table For Adults

The World Health Organization (WHO) recommends a specific body weight range based on Body Mass Index (BMI) values for adults, regardless of gender. This chart is designed for individuals who are 18 years or older. It's important to note that there are separate body mass charts for adults and children since BMI is calculated differently based on age and growth patterns.


The following BMI charts are recommended by the WHO for adults, with separate charts for women and men:

  • Women's & Men's BMI Chart:                           

  • Underweight: Below 18.5

  • Normal weight: 18.5-24.9

  • Overweight: 25.0-29.9

  • Obesity: 30.0 and above

It's important to note that while BMI is a useful tool to assess weight status, it does not account for other factors such as body composition, muscle mass, or bone density. Therefore, it's always best to consult with a healthcare professional to determine an appropriate and healthy weight range for your specific needs.

What is BMR?

Basal Metabolic Rate (BMR) refers to the rate at which the body uses energy (measured in calories) for essential life functions. Basal metabolism includes involuntary bodily processes that support life, such as blood circulation, breathing, nervous system operations, and regulation of body temperature, among others.


However, it does not include the additional energy required for any physical activities like gym exercises.


Essentially, if you were to spend an entire day in bed without any other physical activity, you would need to consume at least the number of calories equivalent to your BMR to maintain normal body functions.

What Does the Calorie Widget do?

The calorie widget is a helpful tool for those looking to manage their weight, allowing you to calculate the number of calories you need to consume in order to either gain or lose weight.

To use the calorie calculator widget, simply follow two easy steps. Firstly, input your height, age, gender, weight and activity level to calculate your total daily calorie expenditure.


Secondly, input the amount of weight you wish to gain or lose, and the widget will create a calorie surplus or deficit accordingly, helping you to reach your desired weight goal. Based on the amount of weight you wish to gain or lose, you can then adjust your calorie intake or activity level to achieve your desired result.


Remember, calories are used to measure the energy consumed by the body.
