Free BMI Calculator
What is your BMI?
Feel free to use our Free BMI calculator as often as you like.
BMI stands for body mass index and it directly conveys the relationship between your height and body weight. There is a misconception that people believe that their calculated BMI or body mass index is a measure of their body fat. This is not true but the figure you get from our free BMI calculator is a good indicator and assessor of your body condition than purely using body weight alone.
Why is my BMI important?
The figure you get from our free BMI calculator is important because it gives you a good guide to your body composition and from the colour graduated scale you can see where you lie in the range of being underweight to being obese. In general people in what is classed as the normal range (the green band on the colour chart) are perceived to have the lowest health risks.
There are drawbacks to the BMI calculator particularly when applied to athletes and muscle builders. It cannot be assumed that just because your BMI calculator has put you in the obese range that you are in fact too fat. The reason why athletes and muscle builders generally fall into the obese category is because they carry a large proportion of muscle and of course muscle weighs more than body fat. In fact this group of people even though they are towards the top of the scale tend to be in most cases both fit and healthy.
When we look at people at the very lower end of the scale (yellow underweight sector) again there may be some athletes that are extremely lean by body composition and fall in this category. However if you fall to the far left it can be an indication of a weight disorder including malnutrition or starvation.
The FREE BMI calculator uses the following weight categories when calculating your BMI score:
- Underweight = less than 18.5
- Normal Weight = 18.5 – 24.9
- Overweight = 25.0 – 29.9
- Obese = 30.0 or greater
