The minimum size of the tread is given as 11 inches. Staircase risers should be adequately deep to allow a majority of your foot to have enough room to rest on the stair. Rise R Nosing Tread Going G Angle of stairways.

The IBC maximum rise of a single stair flight is 12. The projection of nosing shall not be more than 1 ¼ inches and no less than ¾ inch. The going G must be not more than the tread depth plus a maximum gap of 30 mm between the rear edge of one tread and the nosing of the tread above.

The going shall be not greater than the tread depth TD plus a maximum gap of 30 mm between the rear edge of one tread and the nosing of the tread above. If it is impossible to avoid stairs then proper precautions should be taken. When located at the front of a stair nosing the luminance contrast strip cannot extend down the riser more than 10 mm.

Treads shall have a minimum live loading of 25 kPa or a 22 kN per linear metre or minimum point loading of 1. Stairs Landing shall have a minimum live loading of 25 kPa and minimum point loading of 11 kN applied on 100mm 100mm pad. The minimum length of a landing allows people using a stairway or ramp to rest and reduces the risk of people falling more than one flight of stairs.

Treads need to be a minimum of 240mm going to comply with the building code. Maximum 4-12 inch handrail projection into stairway width on either side.
