It is the length of a line beginning at the inside of the Birdsmouth drawn parallel to the edge of the rafter. Note that this is not the actual end-to-end length of the rafter. Rafter Length - The rafter length result from this calculator represents the Line Length of the Rafter(L). The angle information is valuable when performing roof framing tasks using tools that are not roof-pitch calibrated, such as the Bevel on a circular saw, which is degrees calibrated. The roof pitch calibrations on a Speed Square are also used for quickly marking the pitch cut angles on the head and tail ends of rafters.Īngle - Angle(A) is the roof's Pitch(X) represented in degrees. If you know a roof's Pitch(X), you can use the information to lay out rafters with a Framing Square. Pitch/Slope - Pitch and slope, often used interchangeably on the job site, refer to a roof's Pitch(X) represented as X in 12, where X is the number of inches of vertical rise for every 12 inches of horizontal run. Roof Pitch Calculator Results (Explained) The roof pitch chart is a visual representation of the actual slope of a roof, given the roof's Pitch(X)/Angle(A). Select this option if you know the rafter's Rise(M) and the roof's Pitch(X) and need to determine the Run(R) of the rafter. Run(R) - This option places the Rise(M) and Pitch(X) fields into the Input section and moves the Run(R) to the Results section. Select this option if you know the rafter's Run(R) and the roof's Pitch(X) and need to determine the Rise(M) of the rafter. Rise(M) - This option places the Run(R) and Pitch(X) fields into the Input section of the calculator and moves the Rise(M) field to the Results section. The Pitch(X/12) represents the number of inches of Rise(M) for every 12 inches of Run(R). Pitch(X) - This option (the default) places the Rise and Run fields into the Input section. The Roof Pitch Calculator Input Options (Explained) To determine the ( Y) height, measure from the inside of the Birdsmouth up the calculated Pitch (X in 12) to the top of the rafter. To determine the finished height of the Ridge Beam, add the Rise ( M) and the ( Y) height.
