How do you measure stair treads?

31
Decide how much of the stair step that you want to cover. Say you want a 2-inch border. If you have a step that's 36 inches wide and 12 inches deep, to center your stair tread, you'd measure 2 inches on the right and the left side and 2 inches on the top and the bottom.


Just so, how do you calculate stair treads?

Steps

  1. Measure the height, or "rise," of the space you want to make stairs.
  2. Subtract 6–7 feet (1.8–2.1 m) from the total rise to account for headroom.
  3. Divide the rise by 6 or 7 inches (15 or 18 cm) to find the total number of stairs.
  4. Divide the rise by the number of stairs to find the individual stair rise.

Subsequently, question is, what is the code for stair treads? Stair riser heights shall be 7 inches (178 mm) maximum and 4 inches (102 mm) minimum. Stair tread depths shall be 11 inches (279 mm) minimum. The riser height shall be measured vertically between the leading edges of adjacent treads.

Also asked, what is rise and run of stairs?

A stair rise is the vertical distance from the top of one tread to the top of the next tread. The total run is the overall horizontal distance traveled by the stringer. The total rise is a stairway's overall change in height, from the landing pad to the top of the deck's decking.

Do stair stringers need support?

It depends. Yes, the stringers need to be supported along their length, but they can span a few feet too, depending on 1) the width of the stairs, 2) the number of stringers, and 3) size of riser board. Then, the riser board is fastened to each stringer.

What size board should I use for stair stringers?

bull-nosed decking for your treads, you'll have to keep stringers no more than 16 in. apart and you'll be limited to 32-in. wide stairs with three stringers. For wider stairs, add one or more evenly spaced stringers depending on the width of your stairs and the tread material you choose.

Can you build stairs without stringers?

A traditional staircase built with stringers can be less than optimal for very wide stairs. Box steps instead are the preferred choice because they are simple and can be built to any length. If your deck is low and requires only a few stairs or even just one, then steps without stringers are the way to go.

What is the formula for building 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).

How much does it cost to carpet 13 stairs?

For a stairwell with 13 stairs and one landing:
7+7+2 = 16 inches. 7 inches for each rise and run plus two inches for the nose and overage. 16 inches x 13 stairs = 208 inches. 208 inches/12 = 17.33 (round up) = 18 feet.

How much does it cost to carpet 14 stairs?

As for each step this is 12" deep by 33.5" wide. Multiplying this will give you 2.79 square feet (since 33.5 inches equals 2.70 feet.) Multiply 2.79 square feet by 24 steps and you get a total of 66.96 square feet for the step portion of your stairs.

Can you make your own stair treads?

When you must replace oak stair treads you have two options available to you. One option is to buy new replacement treads. The other option is to make your own. While this option involves a little more work than just buying a new one, it will save you some money and ensure that you get the tread that you want.

What saw to cut stair treads?

For starters, to cut a full 11-1/2" stair tread, a 12" sliding miter saw is best. This will allow you to make a full 12" cut in one pass. Using a 10" or smaller saw that doesn't slide means you'll have to make two cuts on each side of the tread and is very difficult to achieve a quality cut.

How do you hang stair stringers?

Attach the stringers to the deck using angle brackets and 3” galvanized deck screws. Cut a 2x6 board to fit snugly between the two stringers at their base. This will be used to fasten the stairs to the concrete pad. Place the board between the stringers and attach to stringers with 3” galvanized deck screws.

How far should stair tread overhang riser?

Nosings, the overhanging portion, must be curved with a radius under 0.56 inches. If the risers are solid, the nosing must project between 0.75 and 1.25 inches, and must be uniform between two stories, with variations of less than 0.375 inches. This applies to nosings on treads and landings.

What is the most comfortable angle for stairs?

The angle is based on the amount of space available, but is commonly determined by the rise and run of a stair. With a 7 inch riser and an 11 inch tread (this is usually a minimum) you get an angle of arctan(7/11) or 32 degrees. Most carpenters will simply use a framing square to figure this rather than doing trig.

Why do stairs have nosings?

The main purpose of a nosing is to improve the safety of the staircase. As it protrudes a little over the edge of the tread, it provides some extra space for users to place their feet.

Do all stair risers have to be the same height?

Riser height is measured from top of tread to top of tread of the next step. If these are in the same staircase, then they can only vary 3/8" between the shortest riser and the tallest riser.

How thick should stair treads be?

As you may have noted from the sketches and text above, typically building codes for stairs specify minimum stair tread thickness (1" if supported by a riser at front, or 1 1/2" thick treads if the stairs are open-construction without risers), but they do not specify a maximum allowable tread thickness.

How many stairs until you need a landing?

Stairs with more than 36 risers in consecutive flights should have at least one change in direction between flights. For buildings other than dwellings, the maximum number of risers between landings should be 16 for utility stairs and 12 for general access stairs. There should not be any single steps.
