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.

Hello, I’m 13, and I’m 5’7 with a 26 inch waist. Apparently I’m 0.36. I weight around 120 pounds, but I’m fairly muscular. Is this heavy?

Im a 15 year old female, have a height of 5'7, waist of 24 inches and a height/waist ratio of 0.36. Apparently I need to "take care" but how accurate is this as I see no problem with my weight of 48.2 kg.
