My Stairs are old! What width runner carpet should I get?

The Width of a Stair Runner is a Personal Preference! Some people's stair risers and stair treads are old and all scuffed up, they are looking for maximum coverage.

In my professional opinion stair runners should never cover the entire stair, Stairs are never straight and if you only leave a 1-inch gap showing on each side chances are it will look crooked because the separation between the stair runner and the stringer is so close.

Best Practices and the best rule of thumb for new runners!

Stair runners should have at least a 3-inch space on either side of the rug, this way if the stairs are crooked you won't notice as much and a little old wood never hurt anyone.

In North America Most Staircase Runners are Installed from the Bottom Up starting at the First Riser, the carpet runner is stapled on Bottom Riser then stapled under the first stair tread stretched or kicked towards the Next stair riser, tucked into that next stair tread and riser up under or over the next stair tread, this is repeated all the way up the staircase using a tape measure to center your stair runner.
