A BMI Chart or Body Mass Index Chart is a useful tool for visualizing the ranges for underweight, healthy weight, overweight, and obesity based on an individual height. The simplicity of Body Mass Index chart formula has made it extremely popular as an initial diagnosing tool for determining a person’s healthy body weight. The formula does have its demerits because it does not take into account age, frame size, gender, or muscularity.
There are many other formulas besides the BMI that are used for determining ideal weight. Our Ideal Weight Chart includes some additional formulas, but keep in mind that “ideal” weight can be highly subjective, and formulas are usually approximations. Also check out our Weight Loss Charts.
BMI calculator kg
This spreadsheet contains a BMI calculator that uses both the CDC and the NHANES II definitions for BMI. The chart shows your BMI on the spectrum based on the chosen formula and gender. This spreadsheet also contains a worksheet use for creating the BMI charts.
Technically, the CDC and NHANES II definitions use the same BMI formula. It’s only the range of values for each category that is different for each other.
The BMI Formula
BMI is defined as a person’s weight divided by the square of a person’s height, using the metric units kg/m^2.
- Metric Units: BMI = Weight[kg] / ( Height[m] x Height[m] )
- English Units: 703 x Weight[lb] / ( Height[in] x Height[in] )
BMI Chart for Children
BMI is calculated the same way for children as for adults, but the way for determining a “normal” weight is different. Replacement of specific BMI thresholds, a BMI percentile is used to compare to other children of the same age and gender. Just as there are Weight-for-Age, Height-for-Age, and Head Circumference-for-Age growth charts, there are also BMI-for-Age charts.
For children, the weight status category is defined based on the BMI percentile (less than the 5th percentile, 5th to less than the 85th, 85th to less than the 95th, and equal to or greater than 95th, respectively).
