Calculate the ideal body weight for men and women using Creff’s formula based on height and sex

How do you calculate your ideal weight using Creff’s formula? Creff’s formula, which includes age and morphology, is an improved version of the Lorentz formula, which only takes height and sex into account. To find out your ideal weight as accurately as possible, you can also refer to the Lorentz ideal weight formula.

How do you calculate your ideal body weight using Creff’s formula?

Professor AF Creff’s formula, created in the 1970s, is very close to the ideal weight, and is intended to be more “accurate” than any other, provided you take a fair look at your morphology. Ideal weight, according to Creff’s formula, is calculated on the basis of three parameters:

  • Body type
  • Height in centimetres
  • Your age

Discover the formulas:

For an individual with a “normal” build:
Ideal weight (in lbs) = Height (in feet) – 100 + (Age (in years) /10) x 0.9

For an individual with a “large” build:
Ideal weight (in lbs) = Height (in feet) – 100 + (Age (in years) /10) x 0.9 x 1.1

For an individual with a “slender” build:
Ideal weight (in lbs) = Height (in feet) – 100 + (Age (in years) /10) x 0.9 x 0.9

Choose the appropriate formula and determine your ideal weight for good health.

The pros and cons of Creff’s formula:

Advantages: it incorporates the morphology dimension in addition to height and age.

Disadvantages: the use of this formula relies on the distinction between normal, large and slim people. These notions remain relatively vague and subjective. This formula does not take gender into account. It is approximate.

What is the ideal body weight?

Healthy weight refers to a person’s weight that is considered favorable for overall health. This depends on many factors, such asage, height, gender, body composition and general physical condition. Unlike ideal weight, which can be influenced by social stereotypes and slimming ideals, healthy weight focuses on a person’s health and well-being rather than their weight per se.

It’s important to remember that healthy weight can vary considerably from person to person, and that there is no universal definition of healthy weight. Healthcare professionals can help determine a healthy weight based on individual needs, using indicators such as BMI, body composition and general health.

Health weight is therefore a more holistic approach to assessing a person’s health, focusing on overall wellbeing rather than weight alone. Maintaining a healthy lifestyle that includes a balanced diet and regular physical activity is important to achieving and maintaining a healthy weight.

  • Heart disease: Being overweight can increase the risk of heart disease such as hypertension, coronary heart disease and stroke.
  • Type 2 diabetes: Being overweight can increase the risk of developing type 2 diabetes, a chronic disease that affects the body’s ability to produce and use insulin.
  • Respiratory disorders: Being overweight can make breathing more difficult, especially for people with sleep apnea.
  • Joint pain: Being overweight can lead to joint pain, particularly in the knee, hip and foot joints.
  • Cancer: Some studies suggest that being overweight may increase the risk of developing certain types of cancer, such as endometrial, breast, colon and liver cancer.
  • Depression: Being overweight can lead to lower self-esteem and self-confidence, which in turn can lead to depression.
  • Liver disease: Being overweight can increase the risk of developing hepatic steatosis (accumulation of fat in the liver), a condition that can progress to cirrhosis or liver cancer.

All the formulas for calculating your ideal weight

How do you calculate your ideal body weight?

The Lorentz formula, created by Dr Friedrich Lorentz (a member of the Department of Sports Hygiene at the Hamburg Institute) in 1929, is based on the Broca Index and it contains additional parameters, such as the person’s height and sex.

Advantage: It is the most common formula used these days to estimate your ideal weight.

Disadvantage: It’s an approximate formula as it does not take into account age or morphology.

Ideal weight for men(in lbs) = Height (in feet) – 100 – ((height in feet – 150) /4))

Ideal weight for women(in lbs) = Height (in feet) – 100 – ((Height in feet – 150) /2.5))

The Body Mass Index (BMI) is based on a weight-to-height ratio and it is used to determine and assess the risks associated with being underweight or obese.

In order to provide an even more accurate estimate of your ideal weight, this formula takes into account another parameter in addition to your height: your bone structure.

Advantage: It includes bone structure into its calculation, and muscle mass to a certain extent.

Disadvantage: The calculation formula is approximate.

Ideal weight (in lbs) = (Height in feet – 100 + 4 x Wrist circumference in inches) / 2

This is the oldest formula to calculate your ideal body weight: It was invented by Dr Paul Broca, a French surgeon, in 1871.

Advantage: It’s a simple formula that is easy to calculate.

Disadvantage: It’s an approximate calculation: It overestimates weight, not only for women, but also for anyone who is taller than 5 feet.

Ideal weight (in lbs) = Height (in feet) – 100

Dating back to 1891, Bornhardt’s formula was originally devised to determine the build of people enrolled in the army and thus determine their physical aptitude for military service. Although less popular than Broca’s Index, it is nonetheless more reliable and accurate, since it takes into account the individual’s specific build.

Advantage: It includes the chest circumference and, to a certain extent, muscle mass.

Disadvantage : It’s an approximate calculation.

Ideal weight (in lbs) = ((Height (in feet) x Chest circumference (in cm)) / 240

The formula was created by Professor AF Creff in the 1970s, and it offers a precise calculation of your ideal weight, provided that you have an accurate estimate of your body shape and type.

Advantage: It incorporates body morphology into its calculation, in addition to height and age.

Disadvantage: This formula is based on the distinction between “normal”, “broad” and “slender” people. These notions are relatively vague and subjective and thus the calculation remains fairly approximate.

For an individual with a “normal” build:
Ideal weight (in lbs) = Height (in feet) – 100 + (Age (in years) /10) x 0.9

For an individual with a “large” build:
Ideal weight (in lbs) = Height (in feet) – 100 + (Age (in years) /10) x 0.9 x 1.1

For an individual with a “slender” build:
Ideal weight (in lbs) = Height (in feet) – 100 + (Age (in years) /10) x 0.9 x 0.9

This formula was devised by Dr B.J. Devine in 1974. It was originally designed for medicinal dosage purposes. Widely used in English-speaking countries, this formula was employed by major medical and pharmaceutical houses between 1974 and 2000.

Advantage: It allows a given height, measured in feet, to be converted into an ideal weight, in lbs.

Disadvantage: The formula does not take age into account, thus it remains approximate.

Ideal weight for men (in lbs) = 50 (lbs) + 2.3 x [Height (in feet) – 60]

Ideal female weight (in lbs) = 45.5 (lbs) + 2.3 x [Height (in feet)- 60]

* one foot represents 30 centimeters.

The Perrault Formula is also a variation of Broca’s formula.

Advantage: This formula takes age into account.

Disadvantage: It does not take sex into account. However, it’s a very approximate calculation.

Ideal weight (in lbs) = Height (in feet) – 100 + (age (in years)/10) x 0.9
