Visceral Fat Calculator
Visceral fat — the fat stored deep around your organs — is a stronger predictor of metabolic disease than total body fat. Estimate your risk level using your waist-to-height ratio, the most validated simple screening tool.
Your Measurements
Measure at the level of the navel, relaxed (not sucked in).
Your Result
Enter your waist circumference and height, then click Calculate.
📋 What Your Result Means

The gauge above shows where your result sits. The universal WHtR threshold of 0.5 applies across sex and ethnicity — if your waist is more than half your height, your cardiometabolic risk is elevated.
Understanding the 1–59 rating: Your visceral fat rating is derived from your waist-to-height ratio, adjusted for age (visceral fat tends to increase after age 30) and sex (men typically carry more visceral fat at the same WHtR). A rating of 1–12 is Healthy, 13–25 indicates Excess, and 26–59 is High. This is a screening estimate based on body proportions — only CT or MRI imaging can directly measure visceral fat volume.
| WHtR Range | Risk Category | Action |
|---|---|---|
| < 0.40 | Very Low | Maintain healthy habits |
| 0.40 – 0.50 | Low | Healthy range |
| 0.50 – 0.60 | Moderate | Reduce waist circumference |
| > 0.60 | High | Seek clinical assessment |
Why visceral fat is more dangerous than subcutaneous fat: Visceral fat (stored around the liver, intestines, and other organs) is metabolically active tissue. Unlike subcutaneous fat (the fat you can pinch), visceral fat releases inflammatory cytokines (IL-6, TNF-alpha), free fatty acids, and adipokines directly into the portal circulation. This drives insulin resistance, elevates triglycerides, raises blood pressure, and increases systemic inflammation — all independent risk factors for type 2 diabetes, cardiovascular disease, and certain cancers.
Exercise reduces visceral fat preferentially: A meta-analysis by Ohkawara et al. (2007) found that aerobic exercise at moderate to vigorous intensity reduces visceral fat even without dietary changes, and that visceral fat responds to exercise more readily than subcutaneous fat. The study concluded that 10+ MET-hours per week of aerobic activity (roughly 150 minutes of brisk walking or 75 minutes of running) produces measurable visceral fat reduction (DOI: 10.1249/mss.0b013e3180304713).
Absolute waist circumference thresholds: In addition to WHtR, the NHLBI defines increased metabolic risk at waist circumference above 102 cm (40 in) for men and above 88 cm (35 in) for women. If your waist exceeds these values, visceral fat reduction should be a priority regardless of your overall BMI.
WHtR = Waist circumference (cm) ÷ Height (cm)
NHLBI Waist Circumference Thresholds (absolute):
Men: > 102 cm = increased risk | Women: > 88 cm = increased risk
WHtR Universal Threshold: ≥ 0.5 = elevated risk (applies across sex and ethnicity)
Limitations
WHtR does not directly measure visceral fat volume — imaging (CT or MRI) is the gold standard. It cannot distinguish between subcutaneous and visceral abdominal fat. Results should be interpreted alongside other metabolic markers. Measurement technique matters: waist should be measured at the umbilicus level, relaxed, mid-breath.
