Use Slimming World's height/weight chart to:
- Check what range you fall in
- Consider your weight loss goals
- Track your progress
The chart is based on body mass index – BMI. BMI assesses weight in relation to height and is a method used by the government and medical profession for both men and women. You can work out your body mass index using our BMI calculator.
Please note: A BMI guide may not be accurate for people with a high muscle mass.
how to use the BMI chart
Use the Weight Range Chart to the left (click to zoom in) to help you set your weight loss goals.
Line up your height (vertical) measurement, and then your weight (horizontal) measurement. Where the lines cross is where you are in the weight range.
what range am I in?
In this range you're underweight
Intentionally trying to lose weight to reach and stay within this range can be unhealthy. You may not be eating enough food to supply your body with all the nutrients it needs. Being underweight can lead to problems such as osteoporosis and anaemia and also affects fertility.
The healthiest weight range
You're at least risk of developing weight-related medical problems. Your health may not necessarily benefit from further weight loss. It's important not to aim to go below this range.
In this range you may be at greater risk of developing weight-related health problems
Losing weight will reduce this risk and could also improve existing health conditions. Many of our members tell us that their general health has improved significantly since joining Slimming World and following Food Optimising. A number also report that they require less medication now they have lost weight. Find out more about the amazing health benefits Food Optimising can bring here…
In this range your health is at greater risk
Losing weight and keeping it off will improve your health and fitness. Losing as little as just 10% of your body weight could bring enormous health benefits. See how you could benefit from losing JUST 10% of your weight.
The point at which someone's health is at risk due to their weight varies between ethnic groups. It is recommended that Asian (South Asian and Chinese), black African and African Caribbean populations use the area between the dotted lines as an indicator for when their health may be at increased risk due to their weight and the area to the right of the purple dotted line as an indicator that their health is at greater risk.
If you're under 16 years old, or if you're a mum-to-be, the BMI calculator and chart are not suitable to assess your weight range. If you’re aged 11-15, ask in group for Free2Go – a guide for you and your doctor, which features BMI charts suitable for your age range that can be used, with your doctor's support, to assess your current weight.
