The rafter square, also known as a rafter angle triangle, has the shape of an isosceles right triangle with a stop on one leg. The variety of scales and cutouts makes the rafter square a multifunctional tool, ideal for marking lines and angles, as well as serving as a scribing tool and saw guide.
Rafter squares are typically made from steel, aluminum, or plastic and are marked with metric units (millimeters, centimeters) or imperial units (inches). Common metric sizes include 18 cm and 30 cm, while common imperial sizes are 7 inches and 12 inches.
The different scales and cutouts of the rafter square, along with the practical stop edge, are particularly suited for working with wood, whether in carpentry, joinery, or woodworking. The rafter square originally comes from the American context, where it is still primarily used in framing for roof construction and rafters. Hence the name rafter square.
With the rafter square, the pitch or angle for regular rafters, ridge rafters, valley rafters, and hip rafters can be determined.
