How much runner do I need?
A few quick measurements is all it takes. We add a small waste buffer for cutting and pattern matching, so what you order is what you can install.

Estimates only. For winders, pie-shaped treads, or curved staircases, send us a photo and we'll measure with you.
How to measure
- Count your stairs from the bottom step to the top landing.
- Measure one tread depth (the flat surface you step on) and one riser height (the vertical face).
- If you want the runner to wrap over the front edge of the step (a "wrap" install), keep the toggle on — we'll add the nosing allowance for you.
- Add the length of any landings the runner will cross.
