On blue prints architects engineers usually display the pitch of a roof in the format shown on the image where number 4 represents a rise and number 12 represents a length. Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of pitches by using a roof angle calculator and by considering factors like the local climate and roofing materials.

Most roof s have a pitch in the 4 12 to 9 12 range. Enter any angle or fraction of angle to find pitch. Roof pitch calculator results explained. Common roof pitches and equivalent grade degree and radian angles.

Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. Enter any pitch or fraction of pitch to find angle. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
