Making Stairs Wider

It s not as difficult as you.
Making stairs wider. Cut lumber to be at or slightly longer than the tread run in width and as long as the stairs are wide or just wider if you prefer a slight overhang on the ends of your stairs. For stair treads less than 9 inches deep secure a new deeper tread directly on top of the existing tread. This includes the recommended 3 4 to 1 1 4 inch overhang. Clamp the stair gauges to the carpenter s square.
Use the narrow part of the square for clamping the riser gauge and the wider part for the 10 1 4 in. Stairs with 14 inch runs tread widths should have rises of between 5 1 2 and 6 1 2 inches. A stair tread should be at least 9 inches deep. A prime example is the standard stair width.
Lay out the stairs by drawing on the outside of the square sliding the square along until it meets the last mark to learn how to build steps. The 7 11 rule means the risers or vertical boards at the back of each step are no higher than 7 inches. Secure the treads to the steps of the stringers with 2 5 in 6 4 cm screws over each stringer. The stair riser must measure 8 to 8 1 4 inches high.
Most interior steps are built from either hardwood composite material or plywood and can be remodeled for more width. This will create a stair stringer calculator. As long as the 3 foot width standard is met you can expand the stairs width as far as you wish. Building codes typically require that stair treads be within 3 4 inch of 10 inches wide.
Staircase code states that stairs must be 3 feet wide or wider. The landing is made of concrete pavers set in a sand bed. Some builders use the 7 11 rule to create comfortable and safe staircases. For a typical staircase the stair tread must measure 8 1 4 inches to 9 inches deep measure 1 inch thick or more and have a maximum 1 1 2 inch deep nosing.
The tongue is the narrower leg of the framing. Now when handrails are introduced they shall not project more than 4 inches on either side. Attach the other gauge to the body of the square at the run dimension. The wider the treads the more total run the stringers have to span.
Clamp one stair gauge on the square s tongue directly at the rise dimension. At the same time staircase code measurements do allow for some flexibility since most measurements are accompanied by minimums or maximums.
