Tape Measure Markings
Date: 08/11/97 at 11:10:39 From: Anonymous Subject: Tape measure As a construction worker for years, I have noticed that there is a small diamond (or triangle according to the brand) on all tape measures every 19.2 inches, much like the mark at 16 inches (for marking the placement of studs at 16" on center). I had first thought that it was 1/10th of a rod, as 10 of the marks equals 16 feet (192 inches), but a rod is equal to 5 1/2 yards (16.5 feet). It is not really an important issue here, but just something that keeps bothering me, not knowing what it is for, and also knowing that it is put there for a reason, for some sort of measurement. Any help would be greatly appreciated. Thanks! - Greg

If you divide five into 96 inches, it will give 19.2 inches. In other words, 4 into 96" = 24", 5 into 96" = 19.2", and 6 into 96" = 16". These are the normal centerings of wall studs. - Johnny Johnny E.
