BMI Calculator
Please note that the BMI categories used in this calculation are based on general categories and might differ depending on specific health guidelines.

The graph shows the body mass index (BMI) for different combinations of weight and height. BMI is a way of measuring body fat based on weight and height, and it can be used to assess health risks related to obesity or being underweight.
The graph has four colored sections that indicate the ranges of BMI: underweight (blue), normal weight (green), overweight (yellow), and obese (red). A black line on the graph means the ideal weight for each height, which is equivalent to a BMI of 22.5.
To use the chart, you can find your weight on the horizontal axis and your height on the vertical axis, and then see which region your point falls in. For example, if your weight is 70 kg and your height is 1.7 m, your point would fall in the green region, meaning your BMI is normal.
You can also use the chart to see where your BMI would be if you lost or gained weight, or if you became taller. For example, if your height is 1.7 m and your weight is 70 kg, and you wanted to lose 5 kg, your point would move to the left, and your BMI would decrease from 24.2 to 22.5.
The calculation of BMI is based on the following formula:

The chart uses the following cutoff points for the BMI categories:
- Underweight: BMI < 18.5
- Normal weight: 18.5 ≤ BMI < 25
- Overweight: 25 ≤ BMI < 30
- Obese: BMI ≥ 30
Furthermore, the chart is merely a general guide and does not account for other variables like age, gender, bone density, muscle mass, or medical conditions that could have an impact on your health. If you are worried about your health or weight, you should speak with your doctor.
