BMI Calculator

know your BMI

Body Mass Index (BMI) is a handy guide to the healthy weight range for your height, used by the government and health professionals. At Slimming World we’ll never tell you what you should weigh or what your personal target weight should be, however if you’d like some guidance in deciding your personal weight loss goal, BMI serves as a guide for most of us.

To calculate your BMI you need to know your height in meters and your weight in kilograms, then divide weight by height squared. Or you can use our handy calculator below.

Please note: A BMI guide may not be accurate for people with a high muscle mass. If you are under 16 years old, or if you are a mom-to-be, the BMI calculator and chart are not suitable to assess your weight range.
