The banquet table skirts come in different lengths... the longest is 17.5'. The lengths are calibrated for standard tables, like a 6' folding, 6' round, etc. The height is also standard folding table height, about 29-30"

If you search for banquet table skirts, you will often find that a specific color or length is on sale because they have too many at the warehouse. Very affordable. You buy a stick-on roll of the opposite velcro to attach to the layout, then it's easy on/easy off!
