Risers (Fig. 2) are the vertical members at the back of each tread. 1″ surfaced boards (3/4″ net thickness) are the most common material used.
What should the rise and run be for deck stairs?
The stair treads should be at least 36 inches wide. Despite these minimum requirements, we recommend that stairs should be at least 48 inches wide so they don’t feel cramped. The maximum allowable stair rise is 7 3/4 inches, and the minimum stair rise is 4 inches.

What is OSHA standard handrail height?

OSHA states that guardrail must reach a height of 42 inches, plus or minus 3 inches, above the walking-working surface and withstand a force of 200 pounds at any point in a downward or outward direction. If the railing dips below 39 inches, due to the force, the railing is not OSHA compliant.

Which side should handrail be on stairs?
A landing is required for every 12 feet of vertical stairway rise. If the landing is not enclosed or has an open side, then there should be a handrailing along the open side. Ideally, the railing should not have any interruptions so that it could be held onto during a fall without the hand slipping off.
Can I use a 2×4 for a handrail?
