Waist-to-height ratio
—
Unitless anthropometric screening estimate; no diagnosis is assigned
Normalized waist: — cm · height: — cm
About
Waist-to-height ratio (WHtR) divides waist circumference by height. It is a practical anthropometric estimate of central adiposity, not a direct measure of visceral fat and not a stand-alone diagnosis of obesity or cardiometabolic disease.
Formula
Interpretation
What the result represents: A unitless waist-size-to-stature ratio.
Input units: Enter waist and height in centimeters or both in inches. The calculator normalizes both to centimeters.
Measurement: NICE and WHO-based guidance places the tape horizontally midway between the lowest palpable rib and iliac crest, after a natural breath out.
Worked example: Waist 85 cm and height 170 cm gives 0.50. Equivalent inch measurements give the same ratio.
Applicable population: Anthropometric screening in adults and, under applicable guidance, children aged 5 years and older. Age, growth, pregnancy, body shape, population, and measurement method remain relevant.
Interpretation limitations: “Keep the waist below half the height” is a general screening message used in guidance, not a universal diagnostic standard. This result does not establish obesity, visceral adiposity, metabolic syndrome, or individual disease risk.
