Can the width of the landing be less than the width of the stairway?

The width of landings shall not be less than the width of stairways they serve. Every landing shall have a minimum dimension measured in the direction of travel equal to the width of the stairway. Such dimension need not exceed 48 inches (1219 mm) where the stairway has a straight run.

How big should a landing be on stairs?

The minimum recommended stair landing length is 36″ (or a length and width sufficiently greater than the swing of the door if a wider door is present). This stairway landing or platform dimension is often also expressed as “a minimum of 36-inches in the direction of travel.

How big should a landing be?

A minimum landing depth of 36 inches is specified in most building codes. In general, a landing need not be deeper than 4 feet, no matter how wide the stairs are, if it’s at the end of a straight run of stairs.

How much room do you need for a staircase with landing?

A standard staircase occupies 30-square-feet of space above and below the staircase. This is the most common dimension, given an 8-foot ceiling, where the staircase width measures 3-feet (36-inches) and horizontal floor space occupied measures between 9- to 10-feet.

Do you need a landing at the bottom of stairs?

Staircase Landings Every staircase should have a landing at the top and bottom. The width of the landing, measured perpendicular to the direction of travel, must be no less than the width of the staircase. The minimum depth, measured in the direction of travel, is 36 inches.

How long can stairs be without a landing?

The maximum length of a run of stairs is not measured in the number of risers, treads, or length of the stringer. It is defined by the International Residential Code (IRC) and Florida Building Code (FBC) as a maximum of 147 inches (12′-3”) of vertical height between floor levels or landings.

Does the landing count as a step?

Does the landing count as a step? Yes it does. Remember that when counting stairs, you are counting how many times you have to lift your foot. If you have to lift your foot to get onto the landing, then it counts as a step.

How wide should a patio landing be?

Just like a deck, a landing needs to have footings, posts, beams, and joists. The minimum size for a landing is 3 feet by 3 feet or the width of the stair sections meeting at the landing—whichever is greater. As shown in the illustration below, the minimum depth is measured from the nosing of the stair, not the riser.

How do you calculate stairs for landing?

How to Calculate Stairs – Example 1

1. 450mm / 150mm = 3. This tells us that with a riser of 150mm we will need 3 risers/steps.
2. 450mm / 2 = 225mm.
3. Twice the Rise plus the Going (2R + G) should be between 550mm and 700mm.
4. 2 x 150mm + 275mm = 575mm.

How wide should a step be?

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.

Does the landing count as a riser?

Riser: A riser is the vertical measurement of each stair. Tread: The tread is the horizontal section of each stair, sometimes called the run. Landing: A landing is a platform between two flights of stairs.

Can a landing be smaller than the width of a stair?

The width of landing should not be smaller than the width of stairway they serve as illustrated in Figure 7. The dimension of landing in the direction of travelling should be at least equal to the width of the stair and it should not surpass 1219mm where the stairway is a straight run.

What is the purpose of a staircase landing?

Landing in a staircase is a level floor or platform constructed at a location where the direction of stairs changes or between flights of the stair or at the top of stair flight. A typical landing allows the user to rest while climbing the flights of stairs as well as facilitates the change in direction of the stairs.

What is the building code for stairs and landing platforms?

Building Code Citations for Stairway Platforms & Landings. Summary of Recommended Stairway Landing Platform Length (run or dimension in direction of travel) & Landing Platform Width. The minimum recommended stair landing length is 36″ (or a length and width sufficiently greater than the swing of the door if a wider door is present).

What is a quarter turn landing for stairs?

Quarter Space Landing Quarter turn landing is provided when a 90º change in the direction of the stairs is to be made. It is suitable for the L-shaped stairs also known as the quarter-turn stairs. The minimum width of this type of landing must be 750 mm or equal to the width of the stairs.
