# How To Calculate The Pitch Angle Of A Roof

### Enter any angle or fraction of angle to find pitch.

How to calculate the pitch angle of a roof.

Rafter height width from pythagoras remember that at school so. For a simple gable roof the span wall to wall will be twice the size of the run wall to ridge horizontally. The pitch is commonly defined as the ratio of rise over run in the form of x 12. The rise is the height of the roof and the run is the horizontal span as pictured above.

Total height of building. With the help of these roof pitch degree calculator programs you can make sure that your home is nice and balanced. For example if a roof has a pitch of 4 12 then for every 12 inches the building extends horizontally it rises 4 inches. Rise run pitch where pitch is expressed in percent.

Enter any pitch or fraction of pitch to find angle. Rise run rise run slope. Now select the unit of measurement from the drop down menu of the. Rafter rise run from the pythagorean theorem.

Pitch is the incline of the roof represented as the ratio of rise to the span twice the run. To find the angle of a roof in degrees convert the pitch to a slope then convert to degrees by finding the arc tangent of the slope. Here are a couple examples. First of all you have to enter the value of the rise in the given place.

Then enter the value of the run and choose the unit of measurement from the drop down menu. For example if the roof rises 4 feet and the span is 16 feet twice the run then the pitch is 4 16 or 1 4. First convert the pitch to a slope. To do this simply convert the rise and run as a fraction to a decimal form eg.

The roof pitch is the slope of the rafter. How to calculate roof pitch. It always makes sense to the standard roof pitch angle spot on as the benefits of doing so are quite obvious. Divide the slope by two to get the pitch.

First enter the value of the rise and choose the unit of measurement from the drop down menu. If you do need to calculate the pitch an estimate or shortcut is usually more practical than measuring the roof s overall dimensions. The angle of your roof is calculated the same way you d work the angle of a right angled triangle. If you want to know how to find the pitch of a roof then start with a calculator.

Pitch tan angle where angle is the roof pitch expressed in degrees. This is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations. Right after you have to add the value of run in the given space. Now select the unit of measurement from the drop down menu of this.
