If you need to approximately measure an object but there’s no ruler at hand, you can use the fingers of one hand. In accordance with the average human proportions, the distance between the tips of the thumb and forefinger is about 18 cm (7″), and the distance between the thumb and little finger is about 20 cm (7.87″).
Of course, this method isn’t absolutely accurate because each of us has a different hand size. Yet it can be useful if you need to measure a large object with a small ruler: just measure the distance between your fingers in advance.

#1 = false: How wide away is the hand from the eyes? That makes no difference?
#7 = okay. My children will get tattoos on their fingers; the counts from 6 to 10, haha. Or better: all 25 possible results (6..10 * 6..10) on the back-side of the hand.
#10 = false: I have a 110-degrees-hand. My third finger is not 45, it is 30.
