A standard interior staircase should have no more than 15 steps in a row, with a landing provided after 15 steps. It is recommended that the landing measure at least the same as 3 treads. The ideal height between the steps and the ceiling must be 2.15 meters at minimum.
A standard interior staircase has steps each with a rise (height) of 19 cm and a run (horizontal depth) of 23 cm. Research suggests that the stairs would be safer for descent if the run were 28 cm. However, the general rule in the US is 7-11 (a 7 inch rise and 11 inch run) (17.78cm-27.94cm). This means no more than 7 3/4 inches (19.7cm) for the riser (vertical) and a minimum of 10 inches (25.4cm) for the tread.
A standard interior staircase has steps each with a rise (height) of 19 cm and a run (horizontal depth) of 23 cm. Research suggests that the stairs would be safer for descent if the run was 28 cm. Building codes typically require 7 inches in rise for every 11 inches in tread for standard stairs, although stairs can have up to 8 inches in rise.
In conclusion, a standard interior staircase should have no more than 15 steps in a row, with a landing provided after 15 steps. The ideal height between the steps and the ceiling must be 2.15 meters at minimum. Building codes typically require 7 inches in rise for every 11 inches in tread for standard stairs, but stairs can have up to 8 inches in rise.
