I don't know of any seller in the U.S. that calls them logs or meters. Your the only person in a long time from the UK, active on here. Full rolls are 150 ft long. And can be cut in different widths. Like Oracal comes in 30 ft long or 150 ft long. 150 ft is pretty standard for a vinyl shop to use. That is all that I purchase. 150 ft. long Oracal . 15", 24" ,30" widths. Your vinyl supplier is where you should be asking. .
