I just finished a 72" long table runner. It comes nearly to each end of the table because I wanted to cover a feature on the table top. I was afraid it would look funny, but it's perfect. I think there's a large range of lengths that would look good on the same table, but for sale I would make them in the 50 - 60" range. Mine has pointed ends that I like a lot. As an interior designer, I think the longer length makes the table and d.r. look larger.
