## How Do I Calculate My Body Mass Index?

Your body mass index is a body fat measurement based on your height and weight that applies to both adult men and women. The way you calculate your BMI in the English system is to take your weight in pounds (LBS) divided by your height in inches squared (in)2 and then finally multiplying by 703 to get your BMI result. Alternatively, you could just use the BMI calculator we’ve provided below.

### What is a good BMI for my age?

The ideal range for a healthy adult BMI is anywhere from 18.5 to 24.9, and this is taking into account someone over the age of 18. For children and teenagers, the number is closer to their age and height. For instance, a four-year-old child who weighs 120lbs could be considered obese amongst other four-year-olds.

A BMI range between 25 to 29.9 is considered overweight, and a BMI over 30 is considered obese.

### What is the best BMI for a woman?

The general consensus in regards to a healthy BMI is anywhere between 18.5 and 24.9 as a healthy range for any adult regardless of gender. We understand everyone is built differently and thus their ideal BMI could be higher or lower on the range in proportion to that individual’s height, for instance, a woman could have more body fat than a man with the same BMI.

### Does BMI increase with age?

As people get older muscle mass begins to disappear if normal exercise is not a part of the person’s daily routine. Body fat will take the place of lost muscle mass and can be a contributing factor to increasing one’s BMI. Light cardio exercise and a healthy diet will keep any adult’s BMI in check.

### What does the BMI tell you?

Body Mass Index is just that an index or more precisely simply a tool, and not a hard-fast rule. It should not be used as a barometer for your life, but what it can do is tell you if you could be in danger of certain health conditions if you wander into the overweight or obese ranges. High blood pressure, diabetes, breathing problems, and a number of other problems for those in the higher range of obesity.
