When installing a new staircase planning is everything. You must plan materials, measurements, timing, location; everything is important. Chances are you have already thought of and planned for the big things, but sometimes minor details can slip under the radar and turn out to be big hassles at the end of a project. One of these important, but minor details is planning the floor height and taking it into account when calculating the riser height.

The floor height at the bottom and top of a staircase might be as small as ⅜ inch up to around ¾ inch or so, but these fractional measurements can really throw you off. If a riser height does not allow for the ¾ inch floor height, it could end up sticking out and creating a tripping hazard. In addition, if stairs are not evenly flesh with the floor, they will often not be approved during inspection and you will have a whole new problem on your hands.

A less daunting reason, but still important to consider, is that human nature expects an even rise on each stair and believe it or not, ¾ inch difference will often be noticed. If you’ve ever expected a stair to be slightly higher than it is and gotten a falling sensation, then you know what I am talking about. The opposite also occurs that you expect a rise to be lower than it is and you end up pounding your foot down on the stair. To avoid these situations, be extra careful to consider all factors in riser height.
