On my tape measures, the mark shows up as a diamond. The distance is approximately 19.2 inches. This mark is used for determining the spacing of engineered wood beams rather than traditional 2x8's, 2x10's etc. Engineered beams are stronger than traditional wood and the span between them is greater. If you look further on the tape measure, the triangle or diamond mark is repeated at multiples of roughly 19.2 inches to facilitate construction with engineered beams.
Mark the center between studs
If you don't have enough other information about the triangle to allow you to calculate the width, then you have to use a ruler or a tape measure.
Well, .125 is 1/8 of an inch. If the tape measure is marked in sixteenths, 1/8 would be the 2nd line from the beginning of an inch. Then estimate or eyeball 1/4 of the way to the next line and that is rougly .15 on a tape measure. This is how I would figure this out. If someone knows a better way, please share.
A little bit more than 1/4
The answer depends on the units used for the tape measure.
With a ruler, or a measuring tape.
It is five and one tenths of an inch
Use a tape measure!
if each mark is 1/16 inch then 4 marks is 4/16 inch = 1/4 inch
You use a ruler or tape measure.
were is 15/16" of an inch on the measure tape
If you don't have enough other information about the triangle to allow you to calculate the width, then you have to use a ruler or a tape measure.
tape measure, triangle, table saw
A tape measure one inch thick.
A quarter of an inch.
It takes a piece of colored adhesive tape and a centimeter (or inch) tape and basically any thin flat object - better a ruler. Stand next to a wall, put a ruler horizontally on your head and stick the adhesive tape at the point where the ruler reache the wall. Then measure the distance from the floor to the adhesive tape.
The stud distance in houses.
You will not be able to measure to that accuracy using a tape measure. You should have marks at tenths of an inch and so you will get 2.3 inches on the tape measure. If you have a tape measure that has divisions to 1/32 of an inch then 2 and 10/32 is the nearest.
