Custom Stair Runner: Sizing, Options, and What It Costs

What ‘custom’ actually means

A custom stair runner typically refers to one of three things: a runner cut to a bespoke width not commonly stocked, a runner finished with a specific border or binding colour, or a fully made-to-measure runner including landings, winders, and turns sewn to match your exact staircase geometry. Understanding which of these you need shapes both the price and the lead time.

Standard runners come in common widths like 27 in, 32 in, or 36 in (roughly 68 cm, 80 cm, or 90 cm). If your staircase falls outside these common widths, or you want a specific margin gap on either side, a custom width order solves that cleanly rather than forcing a compromise.

Why go custom

• Your staircase has an unusual width that standard rolls do not fit cleanly
• You have winders or a landing that require pattern-matched, sewn pieces
• You want a specific border colour or binding style not offered as standard
• You are matching an existing runner elsewhere in the home
• You want continuous seamless coverage on an extra-long flight

How much runner do I need?

Even for a custom order, the underlying maths does not change. For a 13-step flight: 10 in tread + 7.5 in riser + 0.75 in wrap = 18.25 in per step, totalling 237.25 in. Add 24 in finishing to reach 261.25 in, or 21.77 ft. Add a 10% waste margin for custom cutting and finishing work, bringing the order to roughly 24 ft. In metric: 25 cm + 19 cm + 1.9 cm = 45.9 cm per step, 596.7 cm over 13 steps, plus 60 cm finishing gives 656.7 cm, and with 10% waste that is about 7.3 m. Use the stair runner calculator to plug in your own exact dimensions rather than relying on these averages, especially if your staircase includes a landing or winders.

Realistic cost expectations

For a 13-step flight in a mid-range wool blend, expect a custom order to run $600-1200 in the US or £450-900 in the UK for the runner alone, before installation labour. Fully bespoke stair runners with sewn winders and landing pieces sit at the higher end of that range, and premium natural fibres or hand-knotted options can exceed it significantly.

The ordering process, step by step

A custom order typically starts with an in-home or video measure, where the fitter records tread depth, riser height, staircase width, and the exact shape of any winders or landings. This gets turned into a cutting plan that the workroom uses to sew shaped pieces where needed, rather than relying on a single straight length. Expect to approve a written spec, including fibre, colour, border, and binding, before cutting begins, since custom orders are rarely returnable once made.

Ask for a physical sample of both the field colour and the border colour together, ideally viewed on your own staircase under your own lighting, since colours can shift noticeably between a swatch under shop lighting and the finished product on a dim stairwell.

What drives the price up or down

• Fibre choice, with hand-knotted wool and silk blends at the top of the range
• Number of winders or turns requiring sewn, shaped pieces
• Border and binding complexity, particularly contrast piping or double borders
• Rush turnaround fees if you need the order faster than standard lead time
• Old carpet removal and subfloor repair, often quoted separately from the runner itself

Spec checklist before signing off

Confirm in writing the exact width, the number of steps and any winders covered, the fibre and pile weight, the border colour and width, and the binding method. Also confirm who is responsible for final measuring, since a mismatch between a supplier's remote measurement and the actual staircase is one of the most common sources of dispute on custom orders.

Lead times and scheduling around a custom order

Because custom stair runners are cut and sewn to order rather than pulled from stock, lead times run considerably longer than an off-the-roll purchase. A straightforward custom width order might ship in 2-3 weeks, while a fully bespoke runner with sewn winders, a landing piece, and a custom border can take 6-8 weeks from final measure to delivery. Build this into any renovation schedule, particularly if the stair runner installation is one of the last jobs before move-in, since a late delivery can hold up an entire project timeline.

It is worth asking your supplier for a firm delivery window in writing rather than a vague estimate, and building in a buffer of at least a week before your planned fitting date, since custom workrooms can run behind during peak renovation seasons in spring and early autumn.

Returns and changes once cut

Custom orders are almost always non-returnable once cutting has started, unlike a standard roll purchase which many suppliers will accept back in original condition. Double-check every measurement and colour choice before giving final approval, and ask specifically whether any changes are possible after the order is placed but before cutting begins, since this window, if it exists, is usually your last chance to correct a mistake without cost.

Whatever you decide, get the numbers first: the stair runner calculator doubles as a stair runner length calculator, adding nosing wrap, landings, winders, pattern repeat and waste so you order the right length the first time.
