What is the main purpose of a framing square?

The main purpose of a framing square is to ensure accuracy in layout and angles. A framing square, also known as a carpenter's square, is a tool that allows carpenters to check the squareness of corners and to mark out angles for various cuts and measurements. It consists of two arms: one longer (the blade) and one shorter (the tongue), which form a right angle. This right angle is essential for framing tasks, as it helps in creating precise joints and aligning materials correctly, which are critical for the structural integrity of a build.

Using a framing square, carpenters can create accurate layouts by marking angles and determining measurements for cuts, making it essential for producing square and level structures. This tool is fundamental in ensuring that all pieces of a project fit together seamlessly, contributing to the overall quality and accuracy of the work being performed.
