Broadloom cut to size, or a ready-made runner?
Broadloom is carpet sold on a roll, typically 4 m or 5 m wide in the UK and 12 or 15 ft wide in the US, from which a retailer cuts a strip to your chosen width and binds or serges the raw edges. A ready-made runner is pre-cut and pre-finished at a small number of fixed widths, usually sold by the linear foot or metre and simply trimmed to length at each end. Both end up looking identical once fitted, but the buying process, lead time and cost structure differ.
| Factor | Broadloom cut to order | Ready-made runner |
|---|---|---|
| Width choice | Any width up to the roll width | Fixed stock widths, usually 24-36 in / 60-90 cm |
| Lead time | 1-3 weeks for cutting and binding | Often in stock, ships same week |
| Cost per unit | Lower per sq yd/m for the carpet itself | Higher per linear ft/m but no binding fee |
| Colour matching | One continuous length, single dye lot | May need joining on very long flights |
| Best for | Non-standard widths, long or curved flights | Standard-width straight flights, quick turnaround |
If your staircase is a common width — around 36 in (91 cm) in the US or a similar figure in UK new-builds — a ready-made runner in a standard width will very likely fit with room to spare either side. If your staircase is unusually narrow, unusually wide, curved, or has an awkward winder section, broadloom cut to order is almost always the better route because you are not compromising the width to fit a stock size.
Pile weight and construction in gray
Gray stair runner carpet spans the full range of constructions, and weight matters more on a staircase than in any other room because every fibre on a stair tread takes concentrated abrasion at the nosing edge, unlike a flat floor where wear spreads out.
- Under 1,000 g/m2 (around 30 oz/sq yd): light-duty, fine for a rarely used secondary stair, not for a main flight.
- 1,000-1,500 g/m2 (30-45 oz/sq yd): standard domestic weight, suitable for most family staircases.
- Over 1,500 g/m2 (45+ oz/sq yd): heavy domestic or commercial-grade, the safer choice for a main staircase used daily by a family or in a rental property.
Ask for the wear rating, not just the weight
Two carpets with the same pile weight can wear very differently depending on twist level and fibre type. Ask the supplier for a stated wear or traffic rating (heavy domestic, extra heavy domestic, or commercial) rather than relying on weight alone — it is a better predictor of how the gray will look after two years on a main staircase.
Ordering broadloom: what to specify
- Give the supplier your total run length including wrap allowance per step, not just the visible flight length.
- State your chosen width precisely, and confirm whether the quoted price includes binding both edges.
- Ask whether the roll is wide enough to cut your whole run in one continuous piece with no seam.
- Request the dye lot number and keep it on file in case you ever need a matching offcut for a repair.
- Confirm the pile direction (nap) so it will run consistently down the flight rather than reversing partway.
- Order 0.5 to 1 m (or 1.5 to 3 ft) extra as a repair offcut, kept flat in storage rather than rolled tightly.
What it costs
| Item | Typical US | Typical UK |
|---|---|---|
| Gray broadloom, synthetic, mid weight | $18-32 per sq yd | GBP 15-28 per sq m |
| Gray broadloom, wool-blend, heavy | $35-65 per sq yd | GBP 30-56 per sq m |
| Binding both edges, broadloom cut | $3-7 per linear ft | GBP 3-6 per linear m |
| Ready-made bound runner, mid weight | $22-45 per linear ft | GBP 18-38 per linear m |
| Underlay, stair grade | $4-8 per sq yd | GBP 5-9 per sq m |
| Professional fitting, straight flight | $25-50 per step | GBP 20-42 per step |
For a straight thirteen-step flight, the material cost difference between the two routes is often modest once binding fees are added to broadloom, so the deciding factor is usually width and lead time rather than price. Run your own step count and chosen width through the stair runner calculator before ordering so you can compare like-for-like quotes from more than one supplier.
Underlay and fixing
Gray stair carpet, whether broadloom or ready-made, performs and lasts far better over a proper stair-grade underlay — a dense crumb rubber or firm PU foam cut to the tread width and wrapped over the nosing. Skipping underlay to save cost is the single most common false economy in stair carpet fitting; it roughly halves the life of the nosing edge, which is exactly where a gray carpet shows wear first as a pale, flattened line.
For fixing, staples driven into the crotch of each step (where tread meets riser) give the most secure, permanent result and are the norm in both US and UK trade practice. Gripper strips plus stair rods suit a period property where you want the runner removable, but expect to re-tension the carpet roughly once a year as the fibres and backing settle.
Loop pile or cut pile for gray stair carpet
Construction affects how a gray shows wear as much as fibre or weight does. A loop pile (Berber-style) gray keeps a flatter, more even surface and resists crushing at the nosing well, but a single pulled loop can run visibly across a pale gray field. A cut pile gray has a softer, more velvety look and hides the odd snag better, but crushes and flattens faster on a heavily used nosing edge, showing as a paler worn line sooner than a loop construction would. A cut-and-loop or textured twist gray splits the difference and is a common choice for a main staircase precisely because it disguises wear patterns better than either pure construction alone.
Planning delivery and acclimatisation
Both broadloom and ready-made gray runners should sit indoors, ideally near the staircase, for at least 24 to 48 hours before fitting, so the fibres and backing adjust to your home's temperature and humidity rather than being fitted straight off a cold delivery van. This matters slightly more for wool-content gray carpet than for pure synthetic ranges, since natural fibre reacts more to sudden humidity change. Book fitting a few days after delivery rather than the same day if your schedule allows it, and keep the roll flat or loosely rolled rather than tightly folded in the meantime to avoid a crease line that can take weeks to fully relax out of a pale gray pile.

Frequently asked questions
Is ready-made or broadloom cheaper for gray stair carpet?
Broadloom is usually cheaper per square yard or metre for the carpet itself, but binding fees narrow the gap. Ready-made avoids a separate binding charge but is sold at a higher rate per linear foot or metre. For a standard-width straight flight the totals often land close together, so lead time and width flexibility usually decide it.
Can I join two pieces of gray broadloom on a long staircase?
Yes, but avoid a seam on a visible tread if at all possible — place any join at a riser or within a landing turn where foot contact and flex are lower. A visible seam on gray carpet is more noticeable than on a patterned runner because there is no design to disguise the line.
What pile weight should I choose for gray stair carpet?
Aim for at least 1,000 g/m2 (roughly 30 oz/sq yd) for a lightly used stair, and 1,500 g/m2 (45 oz/sq yd) or more for a main family staircase. Ask specifically for the wear rating alongside the weight, since twist level and fibre type affect durability as much as raw weight.
Does gray carpet need a different underlay to other colours?
No, underlay choice is driven by traffic level and pile type, not colour. Use a dense stair-grade crumb rubber or firm PU foam cut to the tread width and wrapped over the nosing, regardless of whether the carpet on top is gray, beige or any other shade.
How do I get an exact colour match if I need more gray carpet later?
Keep the dye lot number from your original order and request the same lot when reordering, since gray dye batches can shift subtly between production runs. Store a spare offcut flat, out of light, so you always have a physical reference in case a lot number is unavailable in future.
Will a gray runner look too plain on a plain staircase?
A solid gray can look flat on a very plain staircase with little other detail. A fleck, tweed or subtle herringbone weave in gray adds enough texture to avoid a flat, builder-grade look while keeping the same neutral colour advantage as a solid.
How long does gray stair carpet typically last?
A heavy domestic or commercial-grade gray carpet on a main staircase typically lasts 10 to 15 years with proper underlay and regular vacuuming, though households with large dogs or very high daily traffic should expect the lower end of that range, particularly at the top and bottom steps.
Should I choose loop pile or cut pile for gray stair carpet?
A loop or cut-and-loop construction generally hides nosing wear better on a main staircase, since it resists crushing and disguises the flattened line that develops on a heavily used edge. A pure cut pile looks softer and more luxurious but shows that same wear sooner, so reserve it for a lower-traffic secondary stair if you want the softer look without accepting the faster visible wear.
