I don't knwo if it'll work for you sheree, but when I measure my LRs, I put em on the floor right next to the base board, and they kinda just "shimmy-slide" up against it....i bust out the measurin tape and get a quick measurement when they are all stretched out...I may be off by an inch or two, but that's as accurate as I can get. it works for my BPs too.
