How Long Should My Stair Runner Be?
Quick Formula:
Count your Stair Treads and Risers. Multiply the total number of steps by 19 inches, then divide by 12 to get your total footage.
Example: 12 steps x 19" = 228 inches. 228 / 12 = 19 feet. (Always round up! For 12 steps, we recommend 20 Linear Feet to be safe).

Standard Stair Runner Length Chart
For standard straight staircases, use this quick reference guide:
- 10 Stairs = 18 ft Long
- 11 Stairs = 19 ft Long
- 12 Stairs = 20 ft Long
- 13 Stairs = 22 ft Long
- 14 Stairs = 23 ft Long
- 15 Stairs = 25 ft Long
How Wide Should My Stair Runner Be?
A stair runner should typically be 6 to 8 inches narrower than your total stair width. This leaves a beautiful 3 to 4-inch reveal of wood on each side. If your stairs are slightly crooked (very common in older homes), a wider reveal helps hide the imperfections!
Pro Installation Tips
In North America, we almost always install bottom-up. Start at the first riser, staple under the nose, and use a knee-kicker to ensure a tight, professional fit as you move up the staircase.
