Body Mass Index is the main screening tool to indicate whether a person is - based on their height - underweight, overweight or a healthy weight – and how to calculate it is the latest in our best practice series of blog posts.
This post will take you through how and why BMI is used, and then we’ll show you how to use the function which features on all Marsden medical scales fitted with the DP-3810 indicator.
What is BMI?
BMI is probably the most common way of determining overall body health and whether a person is overweight or not.
Because BMI is such a commonly-used measure - simply a person’s weight in kilograms divided by the square of their height in metres - it means national (and international) figures can be compared and the overall body health of a nation can be determined. Alternatively you can calculate it on your Marsden weighing scale by following the instructions below.
If a person’s BMI is out of the healthy BMI range, their health risks may increase significantly.
However, BMI does not provide an indication of the distribution of body fat, and does not adjust for the effects of body shape, therefore it is best to use alongside other body composition readings.

How to calculate BMI quickly and accurately

To switch on the scale press the ON/OFF button. The scale will then start up and display 0.00kg.
Press the BMI button and the bottom display will flash. You can then enter your own or the person you are weighing’s height by using the numeric keypad on the indicator.
Stand on the scale and your weight will be calculated. The BMI reading will be displayed on the bottom of the screen.
