An Overview On
Carpentry squares are a great tool for anyone who needs to lay out and mark patterns in frames, stairways and roofs. They can also be used as straightedges to determine how linear and flat surfaces are.
These tools are also referred to as rafter squares, roofing squares and flat squares. You can find carpentry squares that are designed to fit in your pocket and ones that are made to work with different surfaces such as wood or brick.
They are generally made from aluminum or steel and are shaped like the letter “L.” Though the standard size is 24 inches by 16 inches, they can also be found in other sizes. The longer part is called the blade, and the shorter part is the tongue; these join at the heel.
You’ll find many different types of squares, often specialized for certain jobs. A combination square, for example, can mark lines at 45 degrees, 90 degrees and 135 degrees and includes an adjustable slide ruler. Tri-squares do not have the adjustable rule, so they look like flat steel blades that are riveted at 90° to wooden handles. Drywall squares, speed squares, and many others also exist.
The measuring dimensions are stamped onto the surface and vary by the purpose the tool is designed for. Most carpentry squares are calibrated in inches and fractions of inches; look for ones that are clearly stamped and easy to read.
