and grandparents' height, use the following formula:
Your father's height = F cm (inches)
Your mother's height = M cm (inches)
Your father's father's height = FF cm (inches)
Your father's mother's height = FM cm (inches)
Your mother's father's height = MF cm (inches)
Your mother's mother's height = MM cm (inches)
If you are a male, with 95% certainty,
Your Maximum Natural Height in cm (inches)
= (F + M + FF + FM + MF + MM) / 6 * 1.08 + 8.8 cm (3.5 inches)
If you are a male, with 99% certainty,
Your Maximum Natural Height in cm (inches)
= (F + M + FF + FM + MF + MM) / 6 * 1.08 + 14 cm (5.5 inches)
If you are a female, with 95% certainty,
Your Maximum Natural Height in cm (inches)
= (F + M + FF + FM + MF + MM) / 6 * 0.92 + 6.4 cm (2.5 inches)
If you are a female, with 99% certainty,
Your Maximum Natural Height in cm (inches)
= (F + M + FF + FM + MF + MM) / 6 * 0.92 + 11.4 cm (4.5 inches)
Extensive statistic and scientific research shows the average
height of males is equivalent to the average height of their
parents and grandparents multiply by a conversion factor of 1.08.
This will be most males' natural height. However, 95 out of
100 males' maximum possible natural height is below the sum of
their natural height plus 8.8 cm (3.5 inches), and 99 out of 100
males' maximum possible natural height is below the sum of their
natural height plus 14 cm (5.5 inches).
Similarly, the average height of females is equivalent to the
average height of their parents and grandparents multiply by a
conversion factor of 0.92.
This will be most females' natural height. However, 95 out of 100
females' maximum possible natural height is below the sum of
their natural height plus 6.4 cm (2.5 inches), and 99 out of 100
females' maximum possible natural height is below the sum of
their natural height plus 11.4 cm (4.5 inches).
