go to a reputable high end floor coverings retailer and discuss this with them. Especially ones that specialize in wovens and sewing. as long as there is a lengthwise pattern match in the runner, almmost any runner pattern can be made to line up but this can requires alot of angle cutting, seaming/sewing and pattern dropping because of the stair angles and radius'es, which end up consuming exponentially more runner material, and the larger the pattern match the more material is consumed to line up the patterns, because of waste factor in making the patterns line up. Expect alot of seaming or sewing. Expect to pay top dollar ... probably more than what you figure as top dollar. Most people specializing in this type of work will want or require you to purchase their materials. It's all custom work.

cand1781, I showed your pattern to my husband. He said it's not going to line up if you look at each individual step. Being a curved staircase you'd have to square it at the front of each step but the overall affect will look good and he's never had anyone complain (he's world famous for his staircase runners) :) BTW, there is a difference between a runner and carpeted stairs. A runner has to be templated and bound and goes over an existing wood staircase vs installed over a subfloor with stained wood (or tile) on each side of the stair. Is that what you're doing? What he said would work better is a smaller pattern or something with florals and/or vines, but what you're looking at will be fine if it's installed correctly. This is the only picture I have. It's winding but a much smaller pattern (if it even is a pattern). I just happen to be with him one day when he needed to stop by this house and tie in the stair with the landing at the top.

Hey Happy New Year! You could do a overlapp of the carpet runner on the luxary vinyl plank, because before they install the carpet it would have wood edges for the carpet nailed to be put in, thus overlapping would be a problem, and it would best to leave the LVT as is because you are technically creating a second sub-floor on top of the exisitng staircase wood. thanks Purewal Contractors Inc
