Product review (1 stars): Very satisified...
The diameter for our small and larger stove burners measure 6-1/2 and 8-3/4. These Range Kleen drip pans are a perfect fit. (see photo)

UPDATE May 18: These might fit my stove, but it wasn't more than a month before they began to chip. I wondered what the little black slivers were on the stove top, until I looked closer and could see the paint on the drip pans was coming off. I'm would never buy them again, and have changed the star rating from five to one. I would give them zero if I could.
