Waist to height ratio

Waist to height ratio calculatorWaist to height ratio is a simple measurement for assessment of lifestyle risk and overweight. Compared to just measuring waist circumference, waist to height ratio is equally fair for short and tall persons. This calculator is valid for children and adults.

1. Measure your waist circumference at a horizontal line one inch above your belly button.
2. Enter waist circumference and height by turning the dials.

Measuring waist to height ratio is gaining popularity in the scientific society as several studies have found that this is a more valid measurement than BMI. Just measuring waist circumference is inherently biased for people taller or shorter than average population.

This calculator uses the criteria for interpretitation suggested by Ashwell.


Indices of abdominal obesity are better discriminators of cardiovascular risk factors than BMI: a meta-analysis.

A systematic review of waist-to-height ratio as a screening tool for the prediction of cardiovascular disease and diabetes: 0·5 could be a suitable global boundary value.

The last time I was measured, I was 155cm tall. This was about March. My waist is 30in but I can fit into 28in. Am I fat? I feel like I am.

Quoting Abimbola adeyanju:
I am 157cm tall and 44 inches waist is that fat?

Yes. You are at extremely high risk of myocardial infarction (heart attack) and hearr disease. You should reduce your calorie intake (eat less food/eat less high calorie food) in order to lose weight.

You need to either:

A.) Grow until you are 226cm (imppssible)


B.) Lose weight until your waist measures 31 inches (possible)

Yeah, besides black people and muslims, people also often discriminate very short people. I'm 140 and the calculator is only for 150 and up. There should've been a warning "Don't use this if you're 149 and shorter" like on amusement parks there are always height warnings.

Quoting James:
So I'm 18 and 5"2 with a waist of 32 inches. So that's possibly overweight?. Wonderful .-.

Seriously?! I'm only 13 and I'm 5'5" 32 inches waist. Urgh.
