To calculate growth of the child it is necessary to know only two figures authentically: growth of mom and dad. If parents try to learn concrete adult parameters of the kid, also his growth at the age of 1 year will be required.
Wisdom of centuries
Each formula has the creator, but the most popular option of determination of growth of the child lost any touch with the author. Nevertheless, the algorithm inspires trust. To determine growth of the son, parents need to put the indicators of growth expressed in centimeters, to increase this sum by 0.54 then from the received number to take away 4.5. Estimated growth of the daughter is calculated according to the similar scheme, only the total growth of parents is multiplied by 0.51, and from the end result 7.5 are taken away.
Hokera method
Doctor Hoker working in clinic with the exotic name "Mayo" offered own option of how to determine growth of the child in the future. Essence of calculations is as follows: growth of mother and father (in centimeters) develops and divided into 2. The result is an arithmetic average of these numbers. To learn growth of the boy it is necessary to add 6.4. For the girl, on the contrary, to take away 6.4.
Karkusa method
The Czech scientist V. Karkus removed the formula of calculation of growth of the child. For determination of growth at the boy it is necessary to add to growth of mother 1.08, then to add on growth of the father and to reduce the received result twice. Growth of the girl is calculated a little differently. Growth of the father is multiplied by 0.923, summarized with growth of mother and also halved.
Range of values
Professor Vladimir Smirnov, as well as his colleague on researches endocrinologist Gleb Gorbunov, the option of calculation of growth of the child showed serious awareness in this question. Their formula allows to receive not one value, but the whole range between the maximum and minimum growth. To learn the possible growth of the son it is necessary to summarize indicators of own growth, to increase this sum by 12.5 and to divide into 2. Having added to total number 8, it is possible to determine the maximum growth of the boy and on the contrary, having reduced total by 8, the minimum value of growth will be received. Growth of the daughter pays off similarly, only number 12.5 does not increase to total parental growth, and is taken away from it. The previous options of determination of growth at the child offer very hypothetical calculations by which result the mothers and fathers recognize only the most probable growth of children. Real figures can differ from valid in any given party. However there is also a national way allowing to define what will be growth of the child in the future. Following scheme: growth of the child reached in 1 year increases by 1 meter (for boys) or 95 cm (for girls).
