Tape Measure Mystery

You might not use a tape measure that much, but when you do, have you ever noticed all extra numbers and shapes on it?

One of the most mind-bending has to be the black diamonds which are on some versions. They usually sit above the numbers, nestled into the lines which show segments of an inch.

It’s pretty obvious they aren’t just for decoration, but you probably have no idea what they are actually for.

The black diamonds are actually called truss marks (also known as stud or joist marks.) Turns out they are used by people who make a living in construction. They are also helpful for the everyday person too. They help determine the spacing of studs in the walls. So, they can be used as a guide when trying to hang pictures evenly.

Next time you use your tape measure, be sure to use all the numbers and shapes!!
