Mate picked up a couple pans today. I read the review here that indicated they would work in counter oven so mate did not measure when she picked them up. ok, first off, yes the pans are thin with a rolled lip and for less than one dollar they are fine. if you want a 10 dollar pan, buy one. now to the size, these pans are Not 12 inches in diameter, and not close to 12. Pans are a full 13+ inches in diameter. they will not fit in my cuisinart counter convection oven. i have 12" pizza pans and they do fit. so, be certain that this pan will work in your countertop oven. of course these are very well suited to your full size range if you wanted to make a more personal size pizza; 12" or less. anyway...measure your countertop oven width to be sure and also allow for a tiny bit extra.
