Calculation of the ideal weight

Formulas for calculating the ideal weight

The result of these mathematical formulas represents the theoretical ideal weight of the subject according to the author.

Lorenz formula

This formula for calculating the ideal weight does not take into account either the age or the skeletal structure, but it is widely used. Furthermore, it is badly applied in long-limbed and brachytic subjects.

Ideal weight Men = height in cm - 100 - (height in cm - 150) / 4

Ideal weight Women = height in cm - 100 - (height in cm - 150) / 2

Broca's formula

This formula for calculating the ideal weight is the simplest but takes into account only the height; the major limits reside in the mismatch of the ideal weight for medium to high stature.

Ideal weight Males = height in cm - 100

Ideal weight Females = height in cm - 104

Formula by Wan der Vael

This formula considers only the height

Ideal weight Men = (height in cm - 150) x 0.75 + 50

Ideal weight Women = (height in cm - 150) x 0.6 + 50

Berthean's formula

Ideal weight = 0.8 x (height in cm - 100) + age / 2

Perrault's formula

This formula takes into account age and height

Ideal weight = Height in cm - 100 + age / 10 x 0.9

Keys formula

Ideal weight Men = (height in m) ² x 22.1

Ideal weight Women = (height in m) ² x 20.6

Travia formula

Ideal weight = (1.012 x height in cm) - 107.5

Livi's formula

Ideal weight = (2.37 x height in m) 3

Buffon, Roher and Bardeen, later confirmed by Quételet and Martin

Ideal weight Men = (1.40 x height in dm3) / 100

Ideal weight Woman = (135 x height in dm3) / 100
