What to do when the delivery arrives
First, inspect the outer packaging. If it is torn, crushed, or shows signs of water damage, point it out to the driver immediately and make a note on the delivery note. Ideally, unroll the first few feet of the runner in front of the driver if you suspect the contents are damaged.
Storage and preparation
Once delivered, do not keep the runner wrapped tightly in plastic for weeks. Natural fibres like sisal or wool need to 'breathe'. Store it in a cool, dry, and clean room, ideally lying flat or standing vertically—but be careful not to bend or kink it, as this can create permanent creases.
How much runner do I need?
For a 13-step flight: 10 in tread + 7.5 in riser + 0.75 in wrap = 18.25 in per step. Total 237.25 in. Adding 24 in for finishing = 261.25 in (21.77 ft). Including a 10% safety margin, aim for 24 ft. Metric: 25 cm tread + 19 cm riser + 1.9 cm wrap = 45.9 cm per step. Total 596.7 cm, plus 60 cm = 656.7 cm. With 10% safety, aim for 7.3 m.

A full-length stair runner is heavy and can be awkward to carry. Enlist help to get it into your house and store it safely until the fitter arrives.
- Check that the label matches your order.
- Store in a clean, dust-free environment.
- Do not fold or kink the runner.
- Allow the runner to unroll and relax before the fitter arrives.
Acclimatisation
Carpets, especially natural fibres, expand and contract with temperature and humidity changes. Bring your runner inside the house at least 24-48 hours before fitting so it can reach room temperature. This makes it much more pliable and easier for the fitter to install without buckling.
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.
Still deciding on material, width or pattern? Our hub on stair runners compares weaves, widths, backings and fitting styles side by side, then hands the numbers straight to the calculator.
Frequently asked questions
What if the runner is damaged?
Photograph the damage, refuse the delivery if it's severe, and contact the supplier immediately.
Can I leave it in the box/plastic?
Short-term is fine, but for long-term storage, remove the plastic to prevent damp or mould buildup.
Should I unroll it?
If you have the space, yes. This allows it to relax, which makes fitting much easier.
Is it heavy?
Yes, especially if it's a dense wool or a natural fibre weave. Get help lifting.
How do I check for dye lot accuracy?
Compare the label on the delivered roll with your invoice.
What should I tell the fitter?
Ensure the runner is ready and waiting in the same room where the work is taking place.
Should I inspect every inch?
Yes, carefully unroll it once to check for defects like fraying or weaving errors before the fitter arrives.
How much space do I need?
Just enough to lay it out flat. If you don't have enough space, standing it vertically in a corner is acceptable.
