Product review (4 stars): correct product size is 9" x 9"
They look great, but I thought I was getting Product Dimensions: 12 x 11.2 x 2 inches ; 1.8 pounds --- what I got was 9" x 9"  Four(4) AppleJack Burner Cover Set... They fit my gas range very nicely.

The plastic bag that they were in measured(12 x 11.2 x 2 inches) made in 1997.
