New BMI calculator – good news for taller people!
The standard BMI calculator has been around since the 1830s. By dividing an individual’s weight by their height an estimated body fat percentage is calculated. Despite this being a standardised ‘tool’ for measuring body mass index, the results can somewhat misleading depending on your height!
Joe average, fits comfortably within the BMI calculator’s ‘sweet spot’ regarding height & weight, however, being tall can result in BMI estimation of being overweight even though this is not actually the case. Alternatively, being short can result in a false positive reading too. Some people can actually be overweight, but their BMI reading places them within the healthy reference range solely due to their height.
Professor Nick Trefethen, of Oxford University’s Mathematical Institute, identified the flaw and set about creating a new BMI calculator. The new formula (1.3 x weight/height2.5) addresses the inaccuracies between height and weight resulting in taller people (over 6ft) dropping down a BMI point and those under 5 feet gaining a point.
