3-Step Ground Contact Pressure-Treated Pine Stair Stringer

Typically steps are rated as rise over run which means height of step over tread depth. The ideal number is 7/10 which means a 7" rise and a 10" tread. That is what I would guess are their dimensions however this is not a hard and fast rule. I believe building code allows for 6/10, 7/10 and 8/10 steps. The best way to chose this number is to measure from the top of the platform to the bottom and then divide this number by 6, 7 or 8 and chose the best number.

Standard is 7". Would be best to measure one at the store.

Will, There is an Installation Guide to click on within the boxed-off Info & Guides section on the product page. That should be of some help to you.

The bottom riser is shorter because that’s the base. So, basically, when you put the treats on each stringer, 2x6s in your case, it will raise the step by 1.5” but the tread on the next riser will raise that step 1.5” too so you never actually raise the steps. Treads are usually an inch thick so the bottom step is 1” less because that step rests on the floor or slab. Stair code is generally steps between 4” and 7”. 8” is a big step and probably too big for your local code. Whatever riser height you have, let’s say 6-3/4”, code generally dictates you can have more than a 3/8” height difference with the bottom or top riser.

5 stringers to maintain at least a 16 inch gap between

It is cut for a 5/4" tread, if you're using 2 by you should cut it down accordingly

16 inches

The rise of the first step measures 6 in., while the rise of the last two steps measures 6-3/4 in. The run of all three steps measures 10 in.

what is the dimensions's of the stair depth? Will "2" 2 x 6's fit?

30 in
