What Does Your Measuring Tape’s Black Diamond Mean?
Those little black diamonds (sometimes triangles) on a tape measure serve a purpose other than decoration, which you may not have considered before. “Black truss” markings are what they’re called. They start at 19.2 inches and reach up to 96 inches in length (eight feet).

What is the point of their existence? There should be five-floor trusses 19 inches apart for every eight-foot piece of wall. The black markings indicate the location of the studs. The center of the first stud in a wall is indicated by the first mark. When it comes to hanging things on the wall, knowing where the studs are can be really helpful!
