45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.
10 degree angle roof.
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.
A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof.
What degree angle is a 12 12 pitch roof.
Enter any angle or fraction of angle to find pitch.
While measuring tap to hear the spoken angle continuously as it changes.
With the use of this converter it will be easier for you to locate a 30 degree roof pitch 20 degree roof pitch 25 degree roof pitch or a 15 degree roof pitch.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
With a mobile device a button will appear.
To convert between american roofing ratios and pitch degrees follow these steps.
However if you to do the process using your own knowledge you can still convert pitch to degrees by dividing the rise and run and get its corresponding measurement.
Roof angles and rafter plumb cuts.
Visit this page on your phone to directly measure pitch and angles.
Other than the 45 roof slope which is 12 in 12 none of the standard roof pitches 5 in 12 6 in 12 etc are equal to a whole degree.
Divide the first part of the ratio by 12 to work out the pitch.
Find the inverse tangent of the pitch to find the angle in degrees.
Common roof pitches and equivalent grade degree and radian angles.
Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio.
Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch.

Roof pitch calculator results explained.
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.
The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72.
Most roof s have a pitch in the 4 12 to 9 12 range.
The triangle diagram will be re drawn to scale with all dimensions marked.
Tap the button to start measuring and lay your device on an angle roof to measure pitch and angle and animate the diagram.
A 12 12 pitch roof has a pitch angle of 45.
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.
