Planning Stairs With a Landing: Splitting the Rise Into Flights

How to plan a staircase with a landing: splitting total rise into two flights, keeping risers equal across both, and laying out a comfortable mid-stair landing.

Question

What makes planning stairs with a landing: splitting the rise into flights useful enough to become a repeatable app workflow?

Why A Landing Changes The Plan

A landing splits one tall staircase into two shorter flights. It is required when a stair is very tall, when the run will not fit the available space, or when a turn is needed. The key challenge is that the riser height must stay equal across both flights, even though the landing interrupts the run. Treating each flight in isolation is how uneven steps creep in.

Total Rise Still Rules Everything

Even with a landing, the total rise from lower floor to upper floor sets the riser count. You divide that total rise into equal risers across both flights combined, not separately. The landing itself counts as one large step, a rise with a deep tread. Plan the riser height once for the whole climb, then assign risers to each flight.

Splitting The Flights

Decide how many risers go below the landing and how many above. The split is often driven by where the landing must sit for the turn or the space, but the riser height stays constant. A common pattern is a near-even split, but an L-shaped or U-shaped stair may put more risers in one flight than the other. The riser height does not change.

Landing Size And Code

A landing generally must be at least as deep as the stair is wide, and codes set minimum landing dimensions for safety. The landing gives a place to pause, turn, and recover footing. Plan it large enough to meet code and to handle the turn comfortably; a cramped landing makes a stair feel awkward and can fail inspection.

Each Flight Gets Its Own Stringers

Below the landing and above the landing are effectively two separate stairs, each with its own set of stringers cut to the shared riser height. The landing is framed as a small platform that both flights connect to. So you cut two stringer sets, but both use the identical rise so the climb feels seamless.

Headroom Across The Turn

Landings and turns are where headroom problems hide. As the upper flight passes over the lower, or as a turn brings the ceiling closer, you must keep the minimum headroom along the whole walking path. Check headroom at the landing and at the top of each flight, not just on the straight runs.

Calculate Each Flight, Share The Rise

The practical workflow is to set the riser height for the total rise, then run each flight through a stair calculator using that fixed riser height and the flight's run. The Stringer app lets you keep both flights as saved projects with matching risers, so the landing stair stays consistent and code-aware end to end.

Field Checklist

  • Divide total rise into equal risers across both flights.
  • Keep riser height identical above and below the landing.
  • Size the landing to at least the stair width and code minimum.
  • Cut separate stringer sets for each flight.
  • Check headroom through the landing and turn.

FAQ

Common questions

How do you plan stairs with a landing?

Set the riser height for the total floor-to-floor rise, divide the risers between the two flights, then lay out each flight with that shared riser height and its own run.

Do both flights need the same riser height?

Yes. Riser height must stay equal across the whole staircase, including across the landing, or the steps will feel uneven and may fail code.

How big should a stair landing be?

Generally at least as deep as the stair is wide, and no smaller than your local code minimum. A larger landing is safer and easier to turn on.

Does the landing count as a step?

Effectively yes. The landing is one large step, a rise with a deep tread, in the overall climb, so it is included when dividing the total rise.

Can a landing make a stair fit a smaller space?

Yes. Splitting the run with a landing and a turn lets a tall stair fit a footprint that a single straight run could not.

Where do headroom problems happen on landing stairs?

At the landing and turn, where the ceiling or the upper flight can come close to the walking path. Check headroom along the whole route.
