That s another story for another day though. The first black diamond is at 19 2 and after that black diamonds appear at 38 4 57 6 76 8 and 96 or 8 feet. The next black diamond is 19 2 inches away from the first stud 38 4 inches from the beginning of the tape measure and the diamonds go all the way to the 96 inch mark or 8 feet. The tape measures also come with markings that are supposed to help you when it comes time to space your wall studs.

The tapes that don t have these marks have no guaranteed level of accuracy. The numbers that were mentioned above also come into play here. That is one less stud for every 8 feet of wall counting the beginning and end studs. Your tape measure may look like a simple measurement tool but it s equipped with a rich variety of useful marks that help construction and remodeling professionals work with greater speed and accuracy.
