Comments

It appears that the average sinuosity of the letters in the alphabet is 3.14 (Pi), like the supposed average sinuosity of the rivers in the world.

Examples

			In Calibri the letter 'A' is in a rectangle 1 by 0.75, so l = 0.75. The letter A consists of two sloping lines which length is two times square root of (1^2 + 0.375^2) plus a line length 0.5, so L = 2,636. Therefore the sinuosity of A is 3.515 (2.636 divided by 0.75).

Formula

Sinuosity = L / l, where L is the length of the lines that make up the letter, l is the length of the straight line from the beginning to the end of the letter.
