In this tutorial, we learn how to read a tape measure like a professional. Rulers are awkward and you can't measure something over 13 inches with them. A retractable tape measure will measure as long as you would like and it has different markings on it. It has an inch, half inch, and goes on and on. The smallest is 3 32nd's of an inch. As you become more familiar with measuring the tape measure, you will take more accurate measurements for the projects you're working on. When finished learning, you will never use a ruler again, enjoy!
