The waist-to-height ratio is the best simple indicator of cardiovascular risk and mortality, followed by waist circumference and waist-to-hip ratio.1 For health promotion, you want to keep your waist-to-height ratio below 0.5. This translates to the simple rule “Keep your waist circumference less than half your height”.

For more information on the Waist-to-Height ratio, see waist to height ratio as a screening tool for testosterone deficiency and health risk

Don't forget to print out your results and take them to your doctor on your next visit.

See below for further guidance on how to interpret your waist-to-height ratio.

How to interpret your waist-to-height ratio value:


< 0.4

You might be too thin

0.4 – 0.5

You are a healthy pear

0.5 – 0.6

You are a pear-apple
You have more fat around your waist than is healthy. Exercise more and choose better food options. A value close to 0.6 may indicate that you have testosterone deficiency.2,3 Ask your doctor to check your testosterone level.

> 0.6

You are an unhealthy apple
The fat around your waist is damaging your health and shortening your life expectancy.4 You need to start exercising and eating healthier. You likely have testosterone deficiency.2,3 Tell your doctor you want to have your testosterone level checked.

* As a preparation for your appointment with your doctor you can check yourself for symptoms that might be indicative of testosterone deficiency with the Aging Males’ Symptoms (AMS) scale. A high AMS score combined with a waist-to-height ratio above 0.5 is strongly suggestive of testosterone deficiency.
