How to Measure for a Stair Runner — A Simple Guide
1. Choosing the Right Width
When selecting a stair runner, allow for a margin of at least 3-4 inches on either side between the runner and the edge of the staircase. Unless you are covering the entire step. Our rugs come in any widths. Standard width are approximately 60 cm (24"), 70 cm (27") and 76 cm (29.5") — though actual widths may vary slightly, and some designs are available in multiple width options.
If you already have a target runner width in mind, you can use our website filter to narrow down the choices.
2. Calculating How Much Runner You Need
For straight stairs:
-
Measure one riser (vertical portion) and one tread (horizontal portion), and include the “nose” (the edge where tread meets riser) in your measurement.
-
Confirm that all steps are the same depth — if not, measure each individually.
-
Multiply the number of steps by the needed length per step to get the total required runner length.
For winding or curved stairs:
-
Measure along the outer edge of the stairs — from the top to the bottom — including the riser measurement for each step.
-
For the final riser on a flight, always add an extra 1'7" (50 cm ) per flight as a margin for tolerance.
These steps will help you determine the total meterage required to cover your stairs safely and neatly.
3. Special Considerations
-
Winding stairs: If your staircase turns or curves (e.g., a 90° turn), we recommend a flat-weave runner. Flat-weave is more supple and flexible, making it easier to conform to the shape of winding stairs. In many cases — where there are at least three winding steps — a skilled installer can match the runner’s stripe or pattern at the crutch of the turn for a seamless look.
-
Installation matters: Flat-weave runners require professional fitting to ensure proper tension and a neat finish. We strongly advise using an experienced installer. Ask for their previous work or references to make sure they’ve handled similar stair types.
-
Landing areas: For stair landings or hallways, you have multiple options: fitted landing runners, wall-to-wall carpeting, or loose rugs. Choose based on the flow of your home and how you’d like the different floor spaces connected.
