On a metal tape measure, what is the little diamond at every 19-1/5 inches used for, and who uses this increment? (I know about the one at every 16" used by carpenters for 16-on-center studs).

They mark an alternate spacing for studs. It will fall out on a four by eight piece of plywood. When using engineered studs, or 2x6 studs, 16" o.c. is not always required. This saves material by eliminating excess studs. Insulation is available for this stud width also.

well. im a general contractor and we use it on the floor joists...if you multiply it by 3 it gives you 96" and you save money by only having to use 3 joists instead of 4 every 8 feet.. you can't use it on trusses unless you want to sheet the roof with 3/4" plywood because 7/16 is only rated for 2 foot spans

Joist spacing is quite common at 19 1/4". That is what the diamond indicates.

It is sometimes used for stud, trusses, or rafter spacing. You see it lands on the 8 ft mark for running plywood sheets across the rafters.

96" divided by 5 equals 19.2" Duh!
BTW, Roger, I would never hire you to do any contracting in my house. 3 times 19.2" does not equal 96".

I'm not sure how they use it, but they're for installing roof trusses.
