Pattern repeat and why it costs money
The repeat is the distance before the design starts again. To keep the pattern aligned across flights, landings and winders, the fitter needs slack — the safe allowance is one full repeat per flight and per landing. On a large repeat that is a real cost, not a rounding error.
Ask for the repeat length before you order
Every supplier knows it. Enter it into the calculator and it adds the matching allowance automatically, so you order the right length the first time.

Open the stair runner calculatorPattern by pattern
| Pattern | On stairs | Notes |
|---|---|---|
| Herringbone | Excellent | Directional; keep it running down the flight |
| Stripe (lengthwise) | Excellent | Elongates the flight; needs precise centring |
| Stripe (across) | Good | Emphasises each step; unforgiving of uneven treads |
| Animal print | Excellent | Hides wear and soiling beautifully |
| Large geometric | Straight flights only | Big repeat, big allowance |
| Plaid / tartan | Good | Matching in two directions; use a skilled fitter |
| Small all-over texture | Excellent | Near-zero matching allowance |
Directional weaves
Herringbone, twill and most stripes have a direction. If the runner turns 90 degrees on a landing as one continuous piece, that direction rotates with it and reads as a mistake from below. Piece the landing separately instead, so every surface keeps the pattern upright.
Centring
Centre the pattern, not the physical edge of the runner. On a stripe or a symmetrical geometric, an off-centre repeat is obvious from the bottom of the flight even when the runner itself is perfectly centred. Tell your fitter which one takes priority.
Living with pattern
- Busy patterns hide traffic and pet hair remarkably well.
- High-contrast patterns show a badly aligned joint more than plain runners do.
- Small repeats are cheaper to match and easier to piece around landings.
- Keep a metre of off-cut — a patterned repair is impossible without matching material.
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.
Frequently asked questions
Do I need extra runner for pattern matching?
Yes. Allow one full pattern repeat per flight and per landing so the fitter can align the design. On a large-repeat pattern that can add 10–15% to the total length.
Is herringbone good for a stair runner?
Very. It is hard-wearing, hides marks and looks equally at home in period and modern houses. Keep the direction running down the flight and piece landings separately.
