Calculadora de ratio cintura-altura
El ratio cintura-altura compara tu circunferencia de cintura con tu altura. Una guía muy citada es mantener la cintura por debajo de la mitad de tu altura (“mantén tu cintura a menos de la mitad de tu altura”), que correlaciona bien con el riesgo cardiovascular entre poblaciones.
Introduce tu cintura y altura en las mismas unidades. La calculadora devuelve el ratio y si se sitúa en el rango saludable.
It is a stronger predictor of metabolic risk than BMI for many people, because it captures abdominal fat directly — and the rule is easy to remember: keep your waist under half your height.

Cómo se calcula esto
The waist-to-height ratio divides your waist circumference by your height, using the same units for both. A widely cited guideline is to keep the ratio below 0.5 — "keep your waist to less than half your height" — which correlates well with cardiovascular risk across populations. This calculator returns the ratio and a quick read: below 0.5 is healthy, 0.5–0.6 indicates increased risk, and above 0.6 higher risk.
Unlike BMI, which only relates weight to height, WHtR captures where you carry fat. Excess abdominal fat is more strongly linked to metabolic problems than fat carried on the hips, so WHtR often flags risk that BMI misses, especially across different ethnic groups with different body compositions.
The model uses a single waist measurement and your height, with no adjustment for age, sex, or frame. It does not distinguish subcutaneous from visceral fat (the latter is riskier), and the 0.5 cut-off is a general guideline rather than a clinical threshold. Measure the waist halfway between the bottom of the ribs and the top of the hip bone, after a normal exhale, with the tape snug but not compressing.
Ejemplo resuelto
A 175 cm adult with an 85 cm waist.
- 1Ratio = waist ÷ height = 85 ÷ 175 = 0.486.
- 2At 0.486 the ratio sits just under 0.5, in the healthy range.
- 3If the waist rose to 95 cm, the ratio would be 0.543 — increased risk.
Preguntas frecuentes
- ¿Cuál es un ratio cintura-altura saludable?
- Un ratio por debajo de 0,5 se considera generalmente saludable para la mayoría de los adultos. Entre 0,5 y 0,6 indica riesgo aumentado, y por encima de 0,6 riesgo mayor de enfermedad cardiovascular.
- ¿Cómo se compara el WHtR con el IMC?
- El WHtR capta la grasa abdominal, que el IMC no detecta. A menudo predice el riesgo metabólico mejor que el IMC, especialmente entre distintos grupos étnicos.
- ¿Dónde debo medir la cintura?
- A medio camino entre el borde inferior de las costillas y la parte superior del hueso de la cadera, medido tras una espiración normal, con la cinta ajustada sin comprimir.
- What is a healthy waist-to-height ratio?
- A ratio below 0.5 is generally considered healthy for most adults. Between 0.5 and 0.6 indicates increased risk, and above 0.6 higher risk of cardiovascular disease.
- How does WHtR compare to BMI?
- WHtR captures abdominal fat, which BMI misses. It often predicts metabolic risk better than BMI, especially across different ethnic groups, because where you carry fat matters as much as how much you carry.
