Body Mass Index (BMI) Nomogram
The Java script version of the BMI nomogram has been temporarily removed. It will be made available as soon as possible.
This BMI nomogram is not intended for use with:
- those under 18 years of age,
- and pregnant and lactating women.
Visit the Question and Answer (Q & A) section for more information about weight classification and answers to questions about weight and health.
You can also calculate your BMI using this formula:
BMI = weight(kg)/height(m)2
|Classification||BMI Category (kg/m2)||Risk of developing health problems|
|Normal Weight||18.5 - 24.9||Least|
|Overweight||25.0 - 29.9||Increased|
|Obese class I||30.0 - 34.9||High|
|Obese class II||35.0 - 39.9||Very high|
|Obese class III||>= 40.0||Extremely high|
Note: For persons 65 years and older the 'normal' range may begin slightly above BMI 18.5 and extend into the 'overweight' range.

To clarify risk for each individual, other factors such as lifestyle habits, fitness level, and presence or absence of other health risk conditions also need to be considered.
