1. 7:42–8:55 Calculate Number of Risers From How to Calculate How Many Stairs You Need, Step 3: Calculate the Number of Risers

   Practice calculating the number of risers required for a given floor-to-floor height. For example, if the floor-to-floor height is 3300mm and you aim for a rise of 190mm, dividing 3300 by 190 gives approximately 17.36 risers. Since risers must be of equal size for comfortable use, you cannot have a fractional riser. Instead, round the number of risers (e.g., to 17 or 18) and then divide the total height by the chosen number of risers to get the exact uniform rise dimension for each step. It is crucial to always mention the total floor-to-floor height along with the number of equal parts (risers) when dimensioning, rather than just stating the individual riser height.
