What is BMI? Download our FREE chart!

As a medical weighing scales manufacturer and seller, we deal with BMI on a daily basis. That’s in terms of answering questions about BMI, providing information on how to get BMI from your medical scales, and actually making weighing scales with a BMI function!

But having had people asking from time to time what BMI actually is - we thought we’d provide an explanation of what BMI is, how to find out your BMI… And what your BMI says about you!

Additionally, if you’re a GP surgery, pharmacy or gym/sports centre, we’ve also created a free, A3 BMI chart for you to download and print out. It can be displayed somewhere that centre or practice visitors can see it, and understand if they’re the right weight for their height!

You can download the chart below (simply click on the link and save to your computer) but for now, if you need an explanation of BMI… Here it is!

BMI stands for Body Mass Index. As mentioned above, your BMI can be used to determine if you are a healthy weight for your height. It is a measure of your body fat based on your weight and height.

BMI was introduced in the 19th century by a Belgian mathematician. The formula was produced to measure obesity within the country’s population - and has continued to be used to this day.

Obviously, BMI does not measure body fat directly - merely, it estimates the fat from the height you are. However, BMI is a simple, inexpensive and noninvasive measure of body fat that is used by fitness instructors, GPs and hospitals. Because BMI does not measure body fat directly, it is not used as a diagnostic tool.

From our chart, you can work out your BMI. For most adults, an ideal BMI is in the 18.5 to 24.9 range. If your BMI is 25 or more, you weigh more than is ideal for your height. And, of course, if your BMI is below 18.5, you weigh less than is ideal for your height.

Our BMI chart is only for adults; for those aged 2-20, a different calculation, based on height, weight, age and sex will give the BMI.

You can find out more about BMI for both adults and children here on the NHS website. If you’d like more information on medical weighing scales - or gym weighing scales - that automatically calculate a person’s BMI, browse our products or get in touch with us here.
