Waist to Height Ratio Calculator

Your waist-to-height ratio is a ratio that is determined by dividing the circumference of your waist by your height. Some studies done have determined that this measurement is more accurate for predicting risk of heart attack and stroke than the widely used Body Mass Index (BMI). Enter your waist size and height in either imperial (American/British) or metric units below to see your waist to height ratio. Use the table below to determine your level of risk.
Please note that this is not real medical advice, just a simple calculation to give some insight.
