On some modern stairs, the riser is set at an angle less than 90º, this will not change the working dimension between tread surfaces. Traditional riser angle. The pitched riser.. When numbering the goings and rises for the stairs, it is good practice to number the stairs from going 1 through to the top of the building regardless to how many.

The size of each 'going' and 'riser' in a flight of stairs must be consistent. The goings must be between 220 and 300mm. The risers must be between 150 and 220mm. The total of a going plus 2 risers should be between 550 and 700mm. The maximum angle of the stairs (as measured between the pitch line and the horizontal) is 42 degrees.

Important - To give you the true phisical measurment you need to add on the thickness of the top riser (9.6mm is our standard riser thickness) and the nosing size (our standard nosing size is 20mm) which overlaps the bottom riser. So on your 2676mm you need to add another 30mm (29.6) to give you 2706mm total. METRIC SIZES IN mm's.

Every step on your staircase needs to equal the same run and rise. Basically, building one step 185mm high and the next 220mm high is illegal (due to all the accidents). The rise (height) should be a minimum of 150mm and a maximum of 220mm. The run (tread length) should be a minimum of 223mm and a maximum of 320mm.

Rise/Riser: The rise, or height of a step is measured from the top of one tread to the top of the next tread. It is not the physical height of the riser because this excludes the thickness of the tread. The number of risers, not the number of treads, is used to determine the number of steps that comprise a staircase.

How to calculate stair treads (rise and run) stringer layout Stair treads, Stair stringer

Let's say you're designing a staircase for a domestic property in the UK. According to the regulations, the maximum rise (R) is 220mm and the minimum going (G) is 220mm. If you have a total vertical distance (floor-to-floor height) of 2.64 meters to cover, you would divide this by the maximum rise to find out the number of steps needed.

Ultimate Guide to Stairs Stair Riser and Going Dimensions in mm Design

In order to work out our stair angle we can use a bit of basic trigonometry. Total rise = 2800mm. Total run (when working out the angle) = no of risers x going. Total Run = 14 x 275mm. Total Run = 3850mm (note that when working out the angle the top step 14 is included in the total run) Tan = Opposite / Adjacent. So:

Going and riser dimensions: The purpose of 3.9.1.2 is to achieve constant going and riser dimensions deemed safe for people to walk up and down. This minimises the risk of people overstepping during descent on uneven stairs (due to short goings) and tripping on ascent (due to high risers).
