Standard Step Height This stair calculator computes stair parameters such as rise total run angle and stringer length based on the height run tread and headroom requirements
Sometimes the dimensions of risers and going of treads vary in a flight of stairs This variation should not be more than 6 mm Further dimensions of each individual step can be checked for safety by adding the dimension of the going to 2 x the height of the riser This should be at least 570 mm and no more than 650 mm When it comes to residential stair standards the 2021 International Residential Code IRC establishes minimum requirements for stairs to insure a level of safety to the public Several components are looked at such as stair width headroom riser and tread heights

Stair treads have a minimum allowable depth of 11 28 cm with riser heights between 4 7 10 18 cm Stair nosings can protrude between 1 1 5 2 5 3 8 cm with a maximum riser angle of 30 degrees Stair treads are important for safety comfort and accessibility These notes describe an ideal stairway slope or angle and in a table we give the stairway as well as access ramp steepness expressed as stair or ramp angle slope and as typical step riser height and tread depth dimensions
Standard Stair Riser Height Requirements OSHA 1910 25 c 2 requires standard stairs to h ave a maximum riser height of 9 5 inches 24 cm IBC 1011 5 2 requires that stair riser heights shall be 7 inches 178 mm maximum and 4 inches 102 mm minimum For normal residential home standard size of stairs shall be 3 6 wide and their step height riser shall be 7 step width tread or going shall be 10 exclusive nosing height of flight shall be 2 2 m

When it comes to building stairs there are certain standard dimensions that must be taken into consideration These dimensions are important for safety and comfort when using stairs The size and shape of the stairway the type of steps the angle of the stairway the height and depth of each step and the width of each step all play a role in The standard measurement of the height of the step is 7 5 inches following the American codes For the depth the average number is 10 inches the maximum step riser can go up to 7 75 and can t be less than four inches
