I love how this white stair runner contrasts with the color of the wood and yet allows the spectacular pattern of the railing to be the real standout. It also helps answer two of the most common questions:1. Where should the stair runner end? You have a few choices. In this photo, the stair runner ends just under the lip of the bottom tread. Look closely and you'll notice that they ended it there because that stair has an overhang with lighting under it. At the top, they ended the runner at the back of the top tread. You'll see more options in later photos.2. How wide should the stair runner be? As a general rule of thumb, 4" of bare wood on either side of the stair runner is usually aesthetically pleasing and still allows the runner to be wide enough to give you a comfortable path for walking. But you can vary this depending on the look you want for your stairs.
