# Find out how tall you could be and compare your height to the average American man or woman.

If you're still growing and you'd like to know how tall you could possibly be try using the following height calculator! To calculate your maximum natural height based on your parents 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)

Explanation: Extensive statistic and scientific research shows the average height of a man 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 a woman 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).

So far studies have also shown that the average height for an American man is 69.1 inches (5 feet 9.1 inches) and the average height for an American woman is 63.7 inches (5 feet 3.7 inches).

In order to find out if your height to weight ratio is correct and to determine is you are over or under weight for your height, refer to a height weight chart that is easily obtainable from the internet.
