Understanding your ideal weight is the first step in helping you set targets for weight loss.

‘Body Mass Index’ (BMI) is a simple measure which considers your current weight in relation to your height. For most people, a healthy BMI range is between 18.5 and 25.

Our handy calculator identifies what your current BMI is and suggests what your ideal weight range should be. It also suggests how much weight you need to lose to achieve this.

Note: BMI is not a perfect measure, but is widely used by healthcare professionals. It may not be accurate for people with a high muscle mass or mums-to-be and shouldn’t be used for under-16s. The point at which someone’s health is at risk due to their weight also varies between ethnic groups
