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.
Stair tread riser diagram.
Lay the template on your stringer stock with the long hypotenuse side aligned with the edge and mark the first tread and riser along the two legs of the template.
Steep stairs make climbing more tiring and dangerous while shallow stairs are awkward and inefficient for our human stride.
Laying out your risers and the stair tread is an essential part of the process.
Riser thickness of 1 inch.
1 understanding treads risers and nosings.
Order the length for each piece of landing tread needed.
With these dimensions cut a template with the riser height and the tread depth minus one inch as 2 legs of a right triangle.
Nosing is the portion of the tread that overhangs the front of the riser.
The stair calculator is used for calculating stair rise and run stair angle stringer length step height tread depth and the number of steps required for a given run of stairs.
Order your length of riser as the same length as your treads.
Stair riser heights and stair tread depths should be within the parameters of the code to avoid any potential trip hazards for inconsistencies.
Building stairs can be much simpler when you have accurate information to rely on.
The rise is the vertical dimension from tread to tread.
Count the number of steps.
In doing so we shall calculate the dimensions of the steps and the staircase.
And a stringer width of 12 inches.
This tool will prove to be invaluable to you when you re performing these tasks.
Inconsistencies or variations in risers or treads could interfere with the rhythm of the individual using the stairs.
Running measurements vertically lower floor to top of each tread possible landing heights blue middle to calculate and display upper floor opening and stair head room enter upper floor thickness check the show head room check box and drag the head slider to calculate and animate diagram head room and floor opening.
Often a stair builder will talk about the rise and run of the stair.
The tread on the other hand is the horizontal surface of the stair and the part of the stair you step on.
A uniform flight of stairs provides a safety factor.

Landing tread is used along balconies at landings.
Required 1 to 1 1 2 projection beyond the riser face.
We shall take you through the example calculations for first a standard mount and then a flush mount set of stairs.
Don t forget to add one for each flight of stairs for your total number of risers.
The riser is the vertical surface of the stair.
