Bests & Worsts Reviews from Amazon

I keep seeing the review that this does or does not work on this size or that size pie plate. The problem is there is no standard on the actual size of the plate. But apparently when a manufacturer says a plate is say a 10", most of the time they are referring to inside of the diameter of the outer pie crust lip. Here is the bottom line, and all you need to know since the actual dimensions aren't on the description. The actual size is 11-7/16" on the outer diameter measured from the inside of the lip (see pics). The actual size on the inner diameter is 8-3/16" (see pic).
