USEFUL PERSONAL MEASURES
It is sometimes a great convenience to measure a length of ribbon, lace or other goods without the use of a rule or tape measure; but what shall we use in their place? Look at your thumb—how long is it from the end to the first joint? And the middle finger, from the end to the knuckle on the back of the hand? Isn't it nearly four and one-half inches or one-eighth of a yard? That is what the average grown person's finger measures. To get the correct length of your finger, hold the end of a tape line to the end of the finger with the thumb of the same hand, draw the tape measure tight over the bent finger to the knuckle. This is a very useful measure for short lengths.
Another measure for longer lengths is the distance from the end of your nose, when your head is turned sharply to one side, to the end of your thumb when your arm is stretched straight out from the shoulder in the opposite direction. Measure and find out this distance for yourself by holding the very end of a ribbon, tape or rope with the left hand to the end of the nose, head turned to the left, and with the right hand run the fingers along the edge of the ribbon until it is stretched to arm's length. Marking the ribbon with a pin where the right thumb and forefinger have held it, measure the distance with a yard measure or rule from the end of the ribbon to the pin. This length will be about the same as the standard unit of length used in this country. When measuring a long length of goods, use the point held by the right hand as the starting point to be held by left hand.
If you know the distance between the end of your little finger and the end of your thumb when they are stretched apart, the palm of the hand being flat, you can measure a distance such as the length of a table, shelf, pole, etc. When judging the height of a person, remember that the distance from the top of the head to the chin is about one-ninth of the height of the body. The distance between the middle fingers when the arms are stretched straight out from the shoulders is about equal to the height of the body.
