BMI Calculator
BMI Calculator For A Man: BMI or Body Mass Index (BMI) Calculator can be used to calculate BMI value & corresponding weight status at the time of taking age into consideration. Basically, it’s a measure of body fat based on an individual’s weight and height.
This tool is highly used as a general indicator of whether a person has a healthy body weight for their height.
Mainly, the value derived from the calculation of BMI is used to classify a person as underweight, normal weight, overweight or obese depending on the range within which the value falls.
Being under-weight or over-weight can have significant health issues, so while BMI is an imperfect measure of healthy body weight, it can be a useful indicator of whether additional testing or action is needed.

| Normal | 18.5 – 25 |
| Overweight | 25 – 30 |
| Obese Class I | 30 – 35 |
| Obese Class II | 35 – 40 |
| Obese Class III | > 40 |
BMI Calculation Chart For Children

Here’s an example of a BMI Calculation Chart for children based on the Centers for Disease Control and Prevention (CDC) growth charts –
| Classification | Percentile Range |
| Underweight | <5% |
| Healthy weight | 5% – 85% |
| At risk of overweight | 85% – 95% |
| Overweight | >95% |

BMI Calculator Kids
BMI calculators for kids use specific charts and formulas designed for children and teenagers to assess their BMI percentile.
The BMI percentile compares a child’s BMI to other children of the same age and gender, taking into account their growth patterns.
To use a BMI calculator for kids, you will need the following information:
- Age: The exact age of the child in years.
- Gender: Whether the child is male or female.
- Weight: The weight of the child in kilograms (kg) or pounds (lbs).
- Height: The height of the child in centimeters (cm) or inches (in).
Once you have collected this information, you can enter it into a BMI calculator specifically designed for children.
The calculator will use age- and gender-specific growth charts from organizations such as the World Health Organization (WHO) or the Centers for Disease Control and Prevention (CDC).
It will then calculate the child’s BMI percentile, indicating where they fall in relation to other children of the same age and gender.
BMI-for-age percentile categories commonly used for children include:
- Underweight: Below the 5th percentile
- Healthy weight: 5th percentile to less than the 85th percentile
- Overweight: 85th percentile to less than the 95th percentile
- Obesity: Equal to or greater than the 95th percentile
Using a BMI calculator for kids can be a helpful tool to assess a child’s weight status, but it’s important to interpret the results in conjunction with other factors and consult with a healthcare professional for a comprehensive evaluation of a child’s health.
