Solving mathematical equations can be a fun and challenging way to spend your time.

Measure the 'total rise' (from the surface of the upper floor to the surface of the lower floor). Enter this amount into Total Rise Select a common rise-run combination from Rises-Runs DropDown

12' - 2 = 146 inches of run 8' - 11 = 107 inches of rise divide the rise by the run 107 ÷ 146 = 0.7328767 plug 0.7328767. into an arctan calculation and the result = 36.2369 The stairway is built at an angle of 36.2° Rise and Run/Arctan

Enter Run and Known Pitch, Angle or Rise to Calculate other Values Slope 33.3 % Area 384 in² Pitch Run Scale Visit this page on your Phone to directly measure pitch and angles. With a mobile device, a button will appear. Tap the button to start measuring and lay your device on an angle (roof) to measure pitch and angle and animate the diagram.
