Rise Over Run Roof Pitch Calculator

Here is an online rise and run calculator which helps to calculate pitch slope and angle with the help of rise and run values.

Rise over run roof pitch calculator.

A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. This is rarely is a whole number it is not a rare event and it is not a nightmare. 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. 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.

The rise is the height of the roof and the run is the horizontal span as pictured above. The pitch is commonly defined as the ratio of rise over run in the form of x 12. The triangle diagram will be re drawn to scale with all dimensions marked. 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 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. Drag sliders to animate the results and diagram. Pitch tan angle where angle is the roof pitch expressed in degrees.

Rise run pitch where pitch is expressed in percent. 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. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. Enter the rise and run for the pitch length and angle of the rafter.

As aforementioned there is no standard pitch of a roof. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. Calculate roof pitches with this free and simple online tool. 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 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. The roof pitch is the slope of the rafter.
