Begin by accurately measuring the total floor-to-floor height where the stairs will be installed. Record this measurement precisely, including any fractions (e.g., 119 and 1/8 inches). Next, using a construction calculator like the Construction Master Pro Trig, divide the total height by the planned number of rises (e.g., 16 rises) to determine the individual rise height for each step (e.g., 7 and 7/16 inches). The creator highlights the importance of using actual measured dimensions rather than just relying on plans. Note down the maximum allowable rise height to ensure compliance with building codes (e.g., 7 and 3/4 inches). Sketch a simplified stair profile on a piece of wood, marking each rise and run. Identify the specific riser that will correspond to the main platform height (e.g., the 8th riser).

okay so here's the first step anytime that i'm about to frame stairs i figure i go and i measure my actual floor to floor height so that's 119 and 1 8. the plan says that i have 16 rises i'm gonna divide that that's seven and seven sixteenths so that's good sometimes it's goofy i think our max riser height is seven and three quarters so seven and seven sixteenths
