The dual role of stair rods
While the primary fixation for a stair runner is usually under the tread, stair rods apply additional pressure to the fold of the carpet. This helps prevent the runner from shifting during use, making them a wise functional investment as well as a visual one.
How much runner do I need?
Using our 13-step flight standard (10 in / 25 cm treads, 7.5 in / 19 cm risers), you need 23.5 ft (7.09 m) of runner. Rods simply enhance the final presentation of that material.
| Measurement | US (in/ft) | UK (cm/m) |
|---|---|---|
| Tread run | 10 in | 25 cm |
| Riser height | 7.5 in | 19 cm |
| Per-step total | 18.25 in | 45.9 cm |
| Total (13 steps) | 19.77 ft | 5.97 m |
| With 8% waste | 23.5 ft | 7.09 m |
