From How to Find the Angle of Your Stairs, Step 3: Calculate the stair angle
The video highlights the crucial importance of precisely calculating stair angles, identifying it as the most critical, challenging, and time-consuming phase in stair construction. It introduces a general formula for determining both the upper and bottom angles based on the main 'stair angle'. The stated formulas are: Upper Angle = Your stair angle + 2 degrees; Bottom Angle = (90 degrees - stair angle) + 2 degrees. The presenter illustrates this concept with a hand-drawn diagram of stairs, showing various angles (e.g., 16.5°, 33°, 28.5°) and calculations, explaining that once these core angles are correctly established, they can be consistently duplicated for every rise and run throughout the entire staircase. This approach ensures uniformity and simplifies the subsequent building process, allowing for efficient construction of symmetrical stairs regardless of the total number of steps.

0:01 The most important [music] part and the hardest part and the most time consuming part is making this piece right here. Once we got that figured out, then the [music] rest of this becomes a little bit easier and you're just duplicating your angles on [music] right and left. Now, the cool thing about this particular set of stairs, every single rise, every single run, they're exactly the same [music] on every staircase. So, even though there's different amounts of stairs, my angles should be able to be duplicated [music] for each set of stairs so that as long as I remember these angles or write them down, then I'll know that I'm in the right zone.
