Waist-to-Hip Ratio Calculator

The Waist-to-Hip Ratio Calculator is a free online tool that calculate whr with who health risk classification, visual gauge, age-based reference table, and bmi comparison. It runs entirely in your browser with no installation or sign-up needed.

WHO: below 0.90 male, below 0.80 female. Above these = increasing cardiovascular and metabolic disease risk.

Waist at narrowest point (above navel), hips at widest point of buttocks. Flexible tape, snug not tight, standing.

WHR assesses fat distribution (central vs peripheral) — stronger cardiovascular predictor. BMI measures overall weight/height. Use both together.

A high WHR means more of your body fat is stored centrally, around the abdomen, rather than peripherally on the hips and thighs. This central or visceral fat is the pattern most strongly linked to cardiovascular disease, type 2 diabetes, high blood pressure, and metabolic syndrome, which is why the ratio carries more weight than your waist measurement alone. Under the WHO thresholds this calculator uses, a ratio at or above 1.00 for men or 0.85 for women falls into the high-risk band, with moderate ranges just below. It is a screening signal, not a diagnosis, since ethnicity, age, muscle mass, and existing conditions all shift interpretation. Enter your two measurements above to see exactly which risk category your ratio lands in and how close it sits to the next boundary.

Either works, because the ratio is dimensionless: waist divided by hips cancels out the unit, so a person who is 90 cm by 100 cm gets the identical 0.90 ratio whether the numbers were taken in centimeters or inches. This calculator lets you toggle between metric and imperial and converts inches internally at 2.54 cm per inch, so the math stays consistent no matter which mode you pick. The only thing that matters is measuring both the waist and the hips with the same unit and the same tape technique. If your tape only shows inches, just switch the tool to imperial and enter the raw values directly rather than converting by hand. Choose your preferred unit above, type both figures, and the result updates instantly to three decimal places.

Body composition shifts over the decades: muscle mass tends to decline while fat redistributes, so the ratio that signals low risk drifts slightly upward as you get older. That is why this calculator includes an age-based reference table alongside the single WHO cutoff. For men, the low-risk threshold sits near 0.83 in the 20s and rises toward 0.92 past age 70; for women it climbs gradually across the same span. Using one fixed number for everyone can mislabel an older adult as high risk or give a younger one false reassurance, so reading your ratio against your own age bracket gives a fairer picture. The flat WHO thresholds remain useful as a quick screen, but the age table adds context. Check the reference table after calculating to see where your ratio falls for your decade.

Place the tape around the widest part of your buttocks, not at the hip bones or the waistline. Stand upright with your feet together and weight evenly distributed, keep the tape level and parallel to the floor all the way around, and hold it snug against the skin without compressing it. Looking in a mirror or having someone check from the side helps confirm you have captured the true widest point, since going too high or too low understates the hip figure and inflates your ratio. Take the reading after a normal exhale rather than sucking in. For consistency, measure at the same time of day each time you track. Because the ratio is sensitive to placement, a centimeter or two off can nudge you into a different band, so accurate tape work matters. Enter your hip and waist figures above to calculate.

Yes. After the calculator produces your ratio, you can copy a formatted text summary to your clipboard with one click, or download the full result as a CSV file. The export captures your waist and hip measurements in your chosen unit, the calculated ratio to three decimals, your sex, and the WHO risk band that applies, so you have a tidy record to paste into a note, email to a coach, or keep for tracking over time. The CSV opens cleanly in any spreadsheet, which makes it easy to log readings across weeks and watch the trend rather than a single snapshot. Nothing leaves your device during this, since everything runs locally in your browser. Calculate your ratio first, then use the copy or download button to keep a copy for your own records.
