Save Comment 97 Like Some stairways are easier to ascend than others, and there are reasons for that. The parameters of s tair design are set by building codes, and there are also recommended configurations based on average human proportions.

There are, for example, tread-width-to-riser height relationships that make stairs more comfortable for the average person to traverse. Building codes set a minimum for staircase width, but wider dimensions are often necessary. Other important considerations are head clearance, railing dimensions and landings.

Calculating Staircase Square Footage Since they require so much space, efficient staircases must be designed. The trick is a balance of comfort and efficiency that satisfies the building code and enhances the architecture of the space.

The length of the run is the total dimension the treads must occupy to complete the required rise. Staircases use significant square footage by the time all the steps are in place, landings are located and headroom has been cleared. Consider that if a tread is 12 inches and you need 19 of them, that is 19 feet for the length of the steps alone. Now add at least 3 ft. When you multiply the ft. Double those figures to account for the hall or path to go around the staircase, and you have square feet for one staircase.

This is the size of a single-car garage. Find an architect on Houzz to design your staircase. Risers and Treads Critical to stair design are the height of each riser and the width of each tread.

All risers should be exactly or nearly the same height. Varying riser heights feel awkward and are difficult to ascend, because we need rhythm when we climb steps. Building codes also mandate equal heights, though slight variations less than three-eighths inch per step are acceptable.

There are some rules of thumb when planning stairs. The first thing to work out is the required rise. That is the distance from the floor at the bottom to the floor at the top. Once you know the rise, you then need to work out the number of required risers steps. The maximum height per riser for a domestic building, in accordance with Building Regulations Document K, is mm, though on most staircases this is mm.

Next you need to work out the size of each tread. Bedroom Design. Closet Design. Laundry Room Design. Staircase Design. Garage Design. Members Area.
