Check your BMI (body mass index)

Use this calculator to see if you underweight, overweight, or in a healthy range for your height

BMI is:
The WHO regards a BMI of less than 18.5 as underweight and may indicate malnutrition, an eating disorder, or other health problems.
A BMI between 18.5 and 25 is considered normal and healthy.
People who fall into this category may be at risk of developing obesity. This was earlier classified as "overweight".
People who have BMI equal or over 30 may have obesity, which is defined as an abnormal or excessive accumulation of fat that may harm health.

The Body Mass Index (BMI) is a numerical value that assesses an individual's body weight in relation to their height. It is calculated using the formula:

BMI=Weight(kg)Height(m)2BMI = \frac{Weight(kg)}{Height(m)^2}

BMI provides a simple way to categorize a person's weight into different categories, such as underweight, normal weight, overweight, and obesity. It is a useful tool for identifying potential health risks associated with being underweight or overweight. However, it has limitations and does not take into account factors like muscle mass and body composition.

Body mass index (BMI) is a value derived from the mass (weight) and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m2, resulting from mass in kilograms (kg) and height in metres (m).
