Which method of measuring weight involves comparing a person weight and height

The answer is BMI. This index has ranges that help indicate whether one is underweight, normal weight, overweight or obese. To calculate BMI, the following formulae are used;

Weight (kg)/height (m) ^ 2

Normal weight = 18.5–24.9

Overweight = 25–29.9

Obesity = BMI of 30 or greater
