Stair Runner with a Landing Turn
The transition between a staircase and a landing is one of the most visible and technically demanding parts of any runner installation.

A landing turn is where a staircase changes direction on a flat landing, usually by 90° (a quarter landing) or 180° (a half landing). It is the most visible part of a runner installation and the one most often done badly. The decisions are simple to describe — carry the runner across the landing or stop it, and how to turn the corner — but each has consequences for material, cost and how the stairs look.
Quarter-landing vs half-landing
| Quarter landing (90°) | Half landing (180°) | |
|---|---|---|
| Runner path | One corner | Two corners, or a straight run across |
| Usual method | Mitred corner or separate landing piece | Two mitres, or landing covered separately |
| Extra length to allow | The full landing run | Both legs of the landing run |
Option 1: carry the runner across the landing
Continuing the runner across the landing gives the strongest, most continuous look. The runner comes up the first flight, crosses the landing, turns and continues up the next flight at the same width and margin. It needs careful planning so the corner falls in the right place and the margins line up with both flights.
Option 2: stop at the landing
The runner can finish at the top riser of the first flight and start again at the bottom riser of the next, leaving the landing bare or covered with a rug or separate carpet. It uses less material and avoids a corner join, and it suits landings that are large or used as a space in their own right.
The art of the mitred corner
To turn a runner through 90° without folding it, the fitter cuts both pieces at 45° and joins them so the edges meet in a diagonal seam. The pile on the second piece now runs in a new direction, so the two halves can look slightly different in some lights; a good fitter plans the cut to keep that change as discreet as possible. A mitre is the cleanest result for bordered or striped runners, because the border carries round the corner unbroken.
Managing pattern flow through the bend
Patterns and stripes need the most planning. Stripes running along the runner turn neatly at a mitre; stripes running across the runner will change direction, which can look abrupt. Patterned runners need the motif centred on both flights, which sometimes means extra material at the corner. Ask the fitter to show you on paper where the pattern will fall before cutting.
Fitting a runner on winder steps
Some staircases turn on wedge-shaped winder steps instead of a flat landing. Winders need each step fitted individually, folding or cutting the runner at the narrow end so it stays centred. The winder stair runner guide covers that in detail.
Securing the inner corner
The inner corner of the turn takes the most traffic because people cut the corner. Make sure the runner is fixed firmly around the turn and at the nosing of the first step of the new flight, and that the seam (if there is one) is sealed and fixed down along its length.
Border continuity on turns
A bound or bordered runner shows mistakes at a corner more than anything else. The border should meet exactly in the mitre. If the runner is bought ready-made with a woven border, check with the supplier that a mitre is possible, as some borders are only woven on the long edges.
Underlay challenges for landing turns
On the landing, the runner usually sits on a continuous underlay rather than separate tread pads. Make sure its thickness matches the pads on the stairs, so the runner does not step up or down at the top riser, and keep it narrower than the runner so it never shows.
Common mistakes in corner fitting
- Folding the runner at the corner instead of cutting it, leaving a bulky lump.
- Margins that line up on one flight but not the other.
- Not allowing enough length for the landing, so the order falls short.
- Pattern or stripes that jump at the corner.
- A seam placed where it is walked on constantly and not fixed down.
Frequently asked questions
- How do you fit a runner around a 90-degree turn?
- This is usually done by mitring the corner or using a 'turn and tuck' method depending on the carpet's thickness and pattern.
- Can I install a runner on winders myself?
- It is significantly more difficult than a straight flight and usually requires professional experience to avoid bunching.
- How do I calculate material for a turn?
- Measure the widest part of each step and add a generous allowance for the turns and tucks required at the corner.
- What is a mitred join?
- A mitre is a diagonal cut at the corner that allows two pieces of runner to meet at a right angle while keeping the pattern aligned.
- Do I need extra rods for a turn?
- Rods are decorative and can be used on straight sections, but they are difficult to align on turns and are often omitted.
