BMI calculator
BMI, or body mass index, is one way of measuring whether you’re a healthy weight for your height.
The result gives an indication of whether you’re a healthy weight for how tall you are, and if not, how over or underweight you are. BMI isn’t always the best measure to use because there are other things that you need to consider when it comes to weight (see our limitations information further down the page). But it can be a useful guide. Simply enter your details into our calculator to find out what your BMI is and whether you’re a healthy weight.
