Rise Over Run Roof Pitch Calculator

If you want to find the roof pitch in the form of x 12 simply calculate the pitch and substitute 12 for the run length.

Rise over run roof pitch calculator.

The roof pitch is the slope of the rafter. Pitch tan angle where angle is the roof pitch expressed in degrees. As aforementioned there is no standard pitch of a roof. Express roof pitch as the ratio of the amount of the vertical rise of a roof or rise over the corresponding horizontal distance or run you write the pitch assuming a run of 12 inches thus the ratio would describe how much a roof rises for each foot of the run.

This is rarely is a whole number it is not a rare event and it is not a nightmare. A roof pitch that is based on a fixed rise and run and does not end up with a whole number is known as a bastard pitch. Enter run and known pitch angle or rise to calculate other dimensions enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch. In roof pitch calculator pitch value can be obtained by dividing n by 12 and divide s by the answer.

Pitch is thus the ratio of the rise in inches to a 12 inch run and is often expressed using a semicolon for example 6 12. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. The rise is the height of the roof and the run is the horizontal span as pictured above.

The triangle diagram will be re drawn to scale with all dimensions marked. Calculate roof pitches with this free and simple online tool. Drag sliders to animate the results and diagram. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch.

To see how pitch impacts the look of a garage and changes cost click the design center button on our pole barn kits page. The roof pitch calculator finds the length of the rafter and the roof slope in degrees and in percents and our roof pitch calculator also finds pitch in inches per foot slope degrees and rise over run. This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. The run is the distance from the outside of the wall to the inside of the ridge.

Rise run pitch where pitch is expressed in percent. Here is an online rise and run calculator which helps to calculate pitch slope and angle with the help of rise and run values. Roof pitch calculator results explained 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.
