How to measure an inch without a ruler

Updated April 17, 2017

There comes a time in every person's life when they need to measure a small object but they do not have a ruler to do so.

  1. Place the object that you intend to measure on a flat surface.

  2. Place the tip of your thumb at the edge of the object and measure back to the first knuckle. The 1-inch mark is established by the line on your palm side of the thumb.

  3. Hold the 1-inch mark with the tip of your index finger on the opposite hand and slide the tip of your thumb to the mark to continue measuring inch by inch.
