Stairs can be whatever you want them to be. It is usually a function of the room you have to work with and the elevation you are trying to bridge. 7 inch rise and 10 inch tread is very common.
you walk upstairs to get onto the top floor you walk downstairs to be on the lowest floor
rise = 7 inches run = 11 inches
not usually
rise and run for stairs
Dear sir/madam, please would you help me to calculate the rise & run of a stairs. Thank you, John.
The total of the rise plus run does not exceed 18" -
Rise divided by run. That is, the height of the stairs divided by how much they measure across (horizontally).
Normally 7" rise and 11" run.
rise/run x 100 is the percent of slope of a ramp, set of stairs, a street, and so forth.
plans for a set of stairs for the front of a new community center use the ratio of rise to run of 2units to 5 units. a.
when you add your rise and your run the two numbers have to equal between 15-17 inches. Typically there are 13.
rise divided by run: a fraction, rise is y and run is x (you run on a horizontal plane) (you rise on a vertical plane)
There are many components to a winding staircase.First know that your inside and outside radius will rise at different angles because your run changes(pie shaped treads)If you need some direction I will need some more info.
Rise over run ! Rise _____ run
It takes more power to run up the same stairs faster.
