ARCHIVED - BMI Chart
The Body Mass Index (BMI) Nomogram is a graph that shows a person's Body Mass Index as the point on the chart nearest the dashed line (representing the Body Mass Index) where height (in inches or centimetres) and weight (in pounds or kilograms) intersect. Height is shown on the x-axis in centimetres or inches, and weight is shown on the y-axis in kilograms or pounds. Dashed lines, representing the Body Mass Index, are displayed on the graph as calculated by the formula of weight (in kilograms) divided by height squared (in metres).BMI Chart
To estimate BMI, locate the point on the chart where height and weight intersect. Read the number on the dashed line closest to this point. For example, if you weigh 69 kg and are 173 cm tall, you have a BMI of approximately 23, which is in Normal Weight.
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 |
|---|---|---|
| Underweight | < 18.5 | Increased |
| 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.
