The current standard for stairs in the US is a maximum of 7" per riser.10' is 120", divided by 7" is just over 17,but since the maximum allowable is 7" you're going to have to have 18 risers at 6 2/3"Don't panic, your framing square has one leg divided into 12ths,8/12 = 2/3
The correct response varies per building codes. However, the most common is 7 3/8".
there are no set inches .... stairs are cut to a RATIO of the amount of space you need to climb [ say to the second floor of a house or to the top of a deck ] the steeper you make the stairs the higher this ratio will be. 10 inches of tread - and 8 inches of rise - is a common ballpark figure ... you cannot just decide i want my steps to be ______ height. you much use math and figure out how many steps can be divided equally into the total height. local building codes sometimes set a minimum and maximum height to the individual risers. making steps with one odd sized riser [ say shorter or higher than all the rest of the stairs so that it comes out correctly- and usually on the bottom step ] is a HUGE no-no as well. things too look up on the web are "framing square" and "stair stringer"
No more than 1-1/4 inch.
A 10/12 means for every foot of run your rise is 10". so, 10' x 10" = 100" rise in 10 feet.
Normally 7" rise and 11" run.
The rise of a stair is the vertical distance between the treads. The term can be used for the height of the full set of stairs. A riser is the vertical board running along the front of the step.
The maximum weight capacity of a stair lift is around 350 pounds. It depends on the brand you get, but the average is between 300 and 400 pounds.
code is no more then 7.5 inches
Minimum tread is 10" and maximum riser is 7.75".
You use the two scale's,leg's, of the square to layout the rise and run of your stair's. Rise = the height of each step example 7.5". Run = the length of each step example 12".
Nosing is not taken into account when calculating initial stair set-out, but added later. The rise of a residential stair in the US is 8" and the run is 10" with a nose of 1". This means that the tread depth is 10", the height from stair to stair is 8" and the tread sticks out 1" over the the tread below. It is still 10" from front to back. A commercial stair is 7" rise, 11" run, 1" nose.
The tread is what you step on, the riser is the part going up. Rise=riserThe tread is what you step on. The riser is the upright piece your toe hits.

there is plenty of information on actual stair const., but not a lot of info. about the pad the stairs start from. Standards say concrete slab 4'' thick . Can this slab be taller or thicker to change stairway rise and run ?
OSHA specifies that walkways over 4'-0 above ground or surrounding surface require railing. International Residential Code requires a guard rail once the deck is 30" or greater above grade.
Only a portion of a wheelchair stair lift is covered under Medicaid. The maximum coverage is generally only about 80% of the total cost. Also be aware that maintenance is NOT covered at all.
