Stair runner fitting guide

Choosing the width

The runner should leave an even margin of exposed tread on both sides. On a typical staircase of around eighty five centimetres, a runner between sixty and seventy centimetres usually looks right, leaving roughly seven to twelve centimetres either side.

Wider looks more generous and hides more of the tread. Narrower shows off more timber but exposes the stringers to wear. Measure the narrowest point of the flight, not the widest, because the runner has to pass everywhere.

Waterfall or cap and band

There are two ways to take a runner over a step. Waterfall lets the carpet fall straight from the nose of the tread down to the next tread, which is quicker and gives a soft, relaxed look. Cap and band pulls the runner tight around the nosing and into the riser, following the shape of the step precisely.

Cap and band is the traditional, tailored finish and shows the profile of the staircase beautifully. It takes longer and uses slightly more material. If your staircase has fine original nosings, it is usually worth it.

Backing, edging and pattern

Runners are either bought as ready made lengths with a woven or stitched border, or cut from broadloom carpet and whipped or bound along both edges. Cut and bind gives you the whole carpet range to choose from, which is why most of our runner work is done that way.

With a pattern, the repeat has to be aligned so it lands consistently on each tread. Ask for that to be confirmed before the carpet is cut, because a stripe that drifts off square up a flight cannot be corrected afterwards.

• Whipped edge: neat wool yarn overstitch, traditional and hard wearing.
• Cotton or linen binding: crisp, slightly more contemporary look.
• Striped and geometric patterns: need careful setting out on winders.
• Wool blend construction: the sensible choice on a staircase that gets daily use.

Rods, gripper and how it is actually held down

A properly fitted runner is held by gripper in the angle of each step and by underlay pads cut to the runner width, exactly like a fitted stair carpet. That is what stops movement and stops the edges curling.

Decorative rods sit on top and are largely cosmetic, which is not a criticism. They look excellent on a period staircase and make the whole flight feel intentional. What they should not be is the only thing holding the runner in place. A runner fixed by rods alone will shift and wear unevenly.

Winders, half landings and awkward flights

Straight flights are simple. Winders, where the steps turn as a wedge, are where the skill shows. Each winder is set out individually so the runner keeps a consistent margin and the pattern stays square to the leading edge of every tread.

Expect winders to add meaningful time, and expect a good fitter to talk you through how the turn will be handled before they start rather than improvising.

What it costs and how it is priced

Runners are priced by the carpet or ready made runner, plus binding or whipping, plus underlay and gripper, plus fitting charged per step. Rods, if you want them, are a separate item and there are two brackets per step.

Because labour is per step, a thirteen step straight flight is much more predictable than a flight with three winders and a half landing. Ask for the step count on the quote so you can see how the number was reached.

Living with a runner

Exposed timber either side will need occasional attention, so it is worth sanding and finishing the treads before the runner goes down rather than after. Vacuum the runner with the pile, and keep an eye on the nosings, which take the most wear.

If you plan a wool runner on a staircase used by a dog every day, choose a tight twist rather than a loop, because claws pull loops far more readily.
