These are usually about 12 by 10, (can't remember the exact size) and can be trimmed to fit the bed of the machine if the machine bed is smaller. The slider has a bottom which tends to adhere to the machine bed without tape etc. The silicone mats for the ovens apparently need to be taped down but are larger, but I don't know how well they compare to the real thing. I have a supreme slider and think it works well. :-D
