Product review (4 stars): The small ones are great, the large one is too big
I was hoping that I wouldn't be one of the few that this product didn't work for 100%. Alas, as others have said before me, the large drip pan is too big. I'll be keeping this set anyway since the others fit and hopefully I'll be able to find a large one that fits my stove. From edge to edge it is nearly 10 inches wide. The inside rim measures about 8.5 inches and the edge inside that measures about 7.5 inches. While my old drip pan that does fit is about 9.5, 8 and 7 1/4 respectively. Hopefully, they'll all fit your stove, though!

Update: I ended up buying the other style of these Range Kleen drip pans from Target and it turns out that I just bought the wrong style pans for my stove. The pans I bought from Amazon are "Style B", but I needed the "Style A" pans which I bought from Target. If I could find out the brand of my stove then I wouldn't have made that mistake.
