BMI Calculator

BMI (Body Mass Index) is a means of checking you are a healthy weight for your height. A BMI > 26 is above the ideal range, meaning you are overweight.

Note: BMI is a reliable indicator for 17 to 70 year old adults, but cannot be used for pregnant or breastfeeding women or people of a very muscular build.

YOUR MEASUREMENTS:

The BMI sets the weight in relation to the square of the body height (kg/m²). With the BMI the body weight can be classified according to the weight classes of the WHO

Classification of the BMI for Adults according to the WHO¹

  • BMI (kg/m2)
  • Category
BMI (kg/m2) < 18,5
Category Underweight
BMI (kg/m2) 18,5–24,9
Category Normal weight
BMI (kg/m2) 25–29,9
Category Overweight
BMI (kg/m2) 30–34,9
Category Grade I Obesity
BMI (kg/m2) 35–39,9
Category Grade II Obesity
BMI (kg/m2) ≥ 40
Category Grade III Obesity

According to the Obesitological Society, the BMI is suitable for making an initial assessment of body weight and determining whether the weight is within the normal or overweight range. However, it does not consider whether the body weight is mainly derived from depot fat or muscle mass, how old the persons are or what gender they have. The distribution of body fat can also play a role.

Long-term studies have shown that people with a higher waist circumference (apple type) also have a higher health risk. The likelihood of developing Type 2 diabetes, heart disease, or high blood pressure is greatly increased. One indicator for “visceral obesity” is the waist measurement.

Calculation of Basal Metabolic Rate using the Harris-Benedict Formula (in kcal):

Men: 66.5 + (13.7 x weight in kg) + (5.0 x height in cm) – (6.8 x age in years)
Women: 655 +(9.6 x weight in kg) + (1.8 x height in cm) – (4.7 x age in years)

Calculation of the total energy rate

Basal Metabolic Rate x activity factor (very light: Basal Metabolic Rate x 1.2, normal: Basal Metabolic Rate x 1.4, moderate: Basal Metabolic Rate x 1.6, active: Basal Metabolic Rate x 1.8, very active: Basal Metabolic Rate x 2.0
