One the the most useful tools in a tradesman"s toolbox is the typical tape measure. Let"s see exactly how to review a ice measure.

You are watching: 29/32 on a tape measure

The tape measure can be marked with united state or English measurements (feet and inches), metric dimensions (meters and also parts that meters: centimeters, millimeters, etc) or both shared on the exact same tape. Many tape measures have common aspects to be able to use castle easily. Most US tape measures have actually both inches and also foot marks. Notice that the 16", 32", 48", 64", etc. Are marked differently 보다 the other inch markers. Part tape measures have small black arrows or pointers with a box approximately the number, other tape measures have these numbers highlighted in red. These numbers refer to the 16" centers for laying out studs and also joists. Many carpenters have actually the 16" centers memorized approximately 8", yet a small help top top the tape measure up is well received once you obtain to 128". And the 16" marks, notice a black color diamond mark every 19.2 inches, likewise called the black truss mark. The was put on the ice cream measure initially to clues the on-center position of residential roof trusses. Rather than placing 6 trusses in 8", every 16", they saved a truss every paper of plywood by spreading them out. Us don"t use this position today with our trusses, which are generally designed because that 24 customs centers.

When you check out a tape measure a tiny knowledge of math is needed. We recognize that 1/2 is the same as 4/8, 8/16, 16/32, etc. We could refer to the 1/2" note as the 16/32" mark however we commonly use the simplest numbers possible. Since we recognize that 16/32 is 1/2, when searching for 15/32" top top the tape measure, because that example, it is the an initial 32nd before the 1/2" mark.

Actually, in the field a carpenter refers to a 32nd as plus or minus a significant fraction. Because that instance, 13/32 is 1/32 much less than 14/32 or 7/16, so we say "7/16 minus" and also 11/32 is 1/32 much more than 10/32 or 5/16, so we say "5/16 plus". This is a fast means of analysis the tape measure on the job as soon as taking a measurement of other to cut it come fit. What you have to do is memorize the typical fractions down to sixteenths.

Here they are:

1/16, 1/8, 3/16, 1/4, 5/16, 3/8, 7/16, 1/2, 9/16, 5/8, 11/16, 3/4, 13/16, 7/8, 15/16 and also the inch mark.

How to read a ice cream Measure

*
notice the size of the graduations on the tape measure transforms with the fraction; 1/2 is the largest, then 1/4 and also 3/4, climate the eighths, sixteenths and the smallest space the thirty-seconds. These divisions are the most common, but you can get a tape measure up in tenths and also hundredths. I have a framing square the divides an inch into one hundredths.

We use thirty-seconds in the stairway calculator, and other instances choose that, just for accuracy due to the fact that when you"re cutting 16 stair risers, if you space 1/16th inch the end on every stair, you are out a entirety inch at the end. Even being 1/32" out offers an error that 1/2"!

Here is a video I made through Dan"s assist (my brother and also webmaster).
