This stair calculator helps you estimate the dimensions of the stairs in a simple way. The rise is the height of the roof and the run is the horizontal span as pictured above. Here we explain and include examples of simple calculations and also examples of using the Tangent function to tell us the roof slope or angle the rise and run of a roof the distance under the ridge to the attic floor and how wide we can build an attic room and still have decent head.

Lets use some previous calculations as examples. What is the roof pitch. The roof pitch is the slope of the rafter.

A flat roof has a pitch of zero in either instance. If youre not sure what that means think of it this way. One way to calculate the rise is to measure the height of the roof at its highest point floor to ceiling and then subtract the height at its lowest point typically from the.

This calculator computes slope as rise over run first output row and slope as rise over slope length second output row. The first number is the rise or the amount of height the roof gains over the horizontal run usually measured in inches. After theyre up you can snap a line to mark and trim the tails in a nice straight line to make up for any ridge warp or marking cutting and fixing errors.

For example roof slope of 412 has a 4 inch rise every. Input 396 rise and 15840 run then click calculate. For example if a roof has a pitch of 412 then for every 12 inches the building extends horizontally it rises 4 inches.
