What does your waist-to-height ratio mean?
Use this waist-to-height ratio calculator to compare your waist measurement with your height. The calculator divides waist by height using the same unit, such as inches or centimeters.
Waist-to-height ratio is one way to look at body fat distribution, especially fat carried around the middle. It is not a diagnosis, but it may help you decide what health markers to discuss with a healthcare professional.
Your result includes a ratio, a signal group, limitations, and related biomarkers such as glucose, A1C, triglycerides, and HDL cholesterol.

A waist-to-height ratio calculator compares your waist size with your height to estimate how your waist measurement relates to body size. It divides waist by height using the same unit. The result can give a general signal about central body fat, but it cannot diagnose diabetes, heart disease, or any other condition.
A waist-to-height ratio under 0.5 is often considered a lower signal for health risks related to abdominal fat. A ratio from 0.5 to 0.59 may be a moderate signal, and 0.6 or higher may be a higher signal. These cutoffs are general guides, not personal medical advice.
To calculate waist-to-height ratio, divide your waist measurement by your height using the same unit, such as inches or centimeters. For example, a 36-inch waist divided by a 70-inch height equals 0.51. Measuring the same way each time helps make repeat results easier to compare.
Waist-to-height ratio and BMI show different things, so one is not always better for every person. BMI compares weight with height, while waist-to-height ratio focuses on waist size compared with height. Waist measurements may better reflect central fat, but neither number diagnoses health conditions by itself.
Waist-to-height ratio may relate to metabolic health markers such as Hemoglobin A1C, fasting glucose, triglycerides, HDL cholesterol, and sometimes insulin. These markers can help show blood sugar and lipid patterns. A healthcare professional can explain which tests are appropriate based on your health history and risk factors.
No, waist-to-height ratio cannot tell whether you have diabetes, prediabetes, insulin resistance, or metabolic syndrome. It can only provide a general signal based on body measurements. Diagnosis requires medical criteria, which may include blood tests, blood pressure readings, waist circumference, symptoms, and a clinician’s evaluation.
A waist-to-height ratio result is only as accurate as your measurements and should be treated as an estimate. Tape placement, posture, breathing, recent meals, pregnancy, body shape, and muscle mass can affect the number. It is most useful when measured consistently and considered with other health information.
