I did not pay attention to the depth on these liners. They fell short by a few inches. The biggest plus on these liners is they are sturdy like having a board underneath my can goods. I made the liners work versus sending them back. I place majority of the liners towards the front of the shelf. I say make the investment if your shelf is 11.25 inches.

This liner was really sturdy! Not cheap plastic like they usually are.
