The modern aesthetic
Black hardware has become a staple of modern design. On a staircase, black stair rods draw the eye and emphasize the geometry of the steps. They pair particularly well with light-coloured runners or high-contrast patterns.
How much runner do I need?
A 13-step flight (10 in / 25 cm treads, 7.5 in / 19 cm risers) requires roughly 23.5 ft (7.09 m) of material, allowing for a standard 0.75 in / 1.9 cm nosing wrap and 8% waste. Ensure your runner sits centered with enough room for rods to extend at least 2 inches past the carpet edges.
| 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 |
