BMI calculator

Insurance and other plans for those with pre-existing conditions.

Our calculator combines data from the BMI charts for adults, and the BMI charts for boys and girls. You can use feet, inches and pounds or centimeters and kilograms without using a body mass index chart or knowing the formula.

BMI is actually calculated using the same body mass index formula for men, women and youth. However, for kids, one usually has to reference a BMI chart for youth - one for girls and one for boys - in order to determine whether a child is:

Underweight or Potentially Anorexic
Normal - in a Healthy Weight Range
At risk of overweight
Over weight or Potentially Obese.

Data from the adult and both children's charts were added to this calculator to make interpreting your BMI a little easier. A BMI chart for youth is interprets the data differently for boys and girls. For adults BMI data for females is interpreted the same way when compared with that of males. A separate BMI chart for males is necessary for kids, however.

BMI can affect whether you qualify for insurance

I'm a health insurance agent by trade and find that BMI is an important factor in determining whether or not someone will qualify for medical insurance. I decided to create this resource for my clients and anyone else who would like to use it.
