## What is the formula for laying out stairs?

Determining the Rise You divide the height by 7 inches; if, say, the floor-to-floor distance is 8 feet, 10 inches (or 106 inches), then you’ll need 15 treads (106 divided by 7 equals 15.14). Next, you divide the height by the number of treads (15 into 106), producing the exact tread height (7.06 inches).

## What angle should stairs be?

30 to 50 degrees
Standard stair angle by application Standard stairs have an angle of 30 to 50 degrees while steep stairs like alternating tread stairs and ship stairs have an angle between 50 and 70 degrees. Ladders have an angle range between 60 and 90 degrees.

## What is the standard step height for stairs?

Riser Heights In the United States, the step height standard should be between 7 or 7 ¾ inches at the most, and no less than 4 inches. You should follow other measurements if given by local building codes. In Canada, the maximum step riser height is 8 ¼ inches.

## What supports a floating staircase?

Traditional staircases typically use two wood stringers, one on either side of the flight of steps. Floating staircases, on the other hand, utilize a metal stair stringer, which supports the staircase from the bottom. Depending on the design, a floating stair may use a double or single stringer.

## What size board do I need to make a stair stringer?

Stringers should always be cut from 2x12s. Notching smaller stock doesn’t leave enough wood to safely carry the loads of a stair. When ordering stringers, allow about 14 inches of stringer length for each step. Look for straight stock with as few knots as possible.

## What is the best way to finish stairs?

Step#1: Sanding. Although all of our treads have undergone automated sanding it is essential that you fine-sand the edges and the top face one more time,to get the

• Step#2: Staining. Experiment first.
• Step#3: Top Coat. Today you still typically get a choice between water-based and/or oil-based polyurethane.
• ## How to build basic stairs?

Calculate Rise and Run Susan Pittard The first step in building stairs is finding the total rise,which is the overall vertical height of the staircase.

• Cut Stringers Susan Pittard Before laying out the steps on a 2×12,decide how the stringers will join the deck.
• Install Treads and Risers

• ## How to build modern curved stairs in 7 steps?

Use the tape measure to determine the vertical rise of your staircase. Decide how high you want each step to be.

• Take into account the amount the curve itself adds to the length of each side of the staircase and make your stringers the appropriate lengths.
• Divide the total rise by the number of steps and subtract the thickness of the tread material.
