What is a stair tread and riser.
The tread depth shall be measured horizontally between the vertical planes of the foremost projection of adjacent treads and at a right angle to the tread s leading edge.
Stair riser heights shall be 7 inches 178 mm maximum and 4 inches 102 mm minimum.
The riser height shall be measured vertically between the leading edges of adjacent treads.
Stair risers are used in buildings of all shapes and sizes.
Total stair tread or total run it is the total horizontal length between two landing platforms.
The risers are the vertical portions of each step that elevate the treads.
The treads are the horizontal pieces that form stairs and they re the parts where you actually step when you climb up a flight of stairs.
The typical interior stair dimension is calculated as the formula riser r tread t 17 inches minimum or 18 inches maximum not including the nosing.

An open riser staircase is one in which the rise a k a the vertical part of the step between each tread is open rather than closed.
This design offers unobstructed views between treads so you can see through the staircase.
Stair treads and risers are key parts of a set of stairs that provide the structure.
Rise it is the vertical height between the risers.
Steep stairs make climbing more tiring and dangerous while shallow stairs are awkward and inefficient for our human stride.
Buildings codes have been created to control the minimum and maximum measurements of risers and treads.
Responding to the movement of the human body the sizes and relationships of stair risers and treads are regulated to make vertical motion safe and easy.
On the other hand stair risers also cover up areas under the stairs that people sometimes don t want to see.
Instead they may use solid side stringers that anchor the treads using metal connectors.
The treads and risers have a beautiful consistent oak surface which can be stained or varnished to compliment your decor.
Considered a modern staircase design which is a popular choice in contemporary homes.

Stair risers are used at all times on the common staircase.
This kit can be used as is for a closed stringer staircase ends of treads are hidden by stringers.
Tread it is the horizontal space where we will rest the foot while climbing.
Risers can either be enclosed or left open as in deck stairs or basement stairs.
