How do you calculate rise and run on stair stringers?

How do you calculate rise and run on stair stringers?

How do I calculate a stair stringer?

1. Start by finding the overall height that the staircase will be.
2. Decide the height or “rise” you’ll want for each step.
3. Divide the total height of the staircase by the height or “rise” you want for each step.

How long of a 2×12 do I need for stairs?

10.5″
We suggest 10.5″ for 2×12 or 2 – 2×6 Treads. Treads may be cut to suit other widths. Either B or C is required.

Can I use 2×8 for stair stringers?

If your first tread steps down from the deck, you must extend the rim joist to create a solid surface below the deck rim to attach it to. You should attach 2×6 or 2×8 support framing under the rim flush to the bottom of the stringer. Mark the location for each stair stringer. Most wood stairs use 16″ on center.

What size timber should I use for stair stringers?

300 x 50 mm
For stringers: 300 x 50 mm DAR/dressed-all-round selected native hardwoods, selected plantation pine, selected to provide relatively straight grained, clear pieces. For cleats: 75 x 38 mm DAR, cut to length to suit width of treads (refer to item No. 1 0).

How to build deck steps without stringers?

1) Determine the overall length and width of the first step frame. The largest step frame will be on the bottom. 2) Once all boards are cut, mark your long frame boards at 16” on center for the bracing. 3) Attach remaining bracers into the frame by nailing or screwing through the 2×6 frame and into each bracing board. 4) Subtract the length of a single stair from the overall length of the last frame. This will be the length of your second stair. 5) First attach the two ends inside the 48” front and back pieces to create the outer frame. Next, fasten the remaining two inside bracers into position. 6) Repeat steps 4 and 5 for all remaining step frames. 7) There are two ways to fasten the box steps together. You could nail/screw through the back of each box frame and directly into the deck. 8) It is now time to install the decking boards.

How to measure and cut stair stringers?

Use a framing square to trace the stair pattern on your stringer board.

Situate the tread arm of the square nearest to the end of the board.

Mark the first step. Holding the square in place with one hand,run the tip of a pencil along the outer edge of the angle.

Slide the square down to draw every next step.

What is a stair string?

A stair stringer (also called ‘string’ or ‘stringer board’) is the housing on either side of a flight of stairs, into which the treads and risers are fixed.

What is a stair molding?

Stair nose molding is used in conjunction with a hardwood floor installation to finish off the step or stairwell where the hardwood floor stops. Stair nose molding is about 4 to 5 inches wide, with a rounded bullnose edge that extends down to cover the edge of the step and is typically placed on the step before the hardwood.
