Bakers Select Non-stick Cookie Sheets 13 1/4 x 9 1/4 Inch- Small

The dimensions are for inside the rim and I needed it to fit in a new tabletop convection oven. Sadly, it was too large for the tabletop, but works well in the regular oven when I'm only doing small quantities or need a 'drip' tray.Needed both inside and outside dimensions. Because of this issue, unlikely to buy similar things onine and waste time returning because dimensions were incomplete and/or misleading. Had they said whether these were the inside or outside dimensions - or better yet provided both, I would have had known if it would fit.

My mom lives on a boat, has a super small loven and limited storage space. She wanted a spare cookie sheet, since she was down to 1 left and it was getting hard to bake those cookies. If you have a full size oven, this might not be for you, but if you need a petitie baking sheet or have storage issues or use baking sheets for heating small items (1 slice of pizza, etc.), this sheet is great.

The cookie sheet is exactly the right size for most of the things I cook. The only thing I don't like about it is that it buckles in the heat of the oven.

I needed this size for a vintage portable convection oven that became my primary oven when my full size oven quite working. They are heavier than expected and have a smooth finish that nothing sticks to. Great buy and I will use them in my full size new oven.
