Product review (5 stars): 22.25x16.25 inches
I had an issue finding a rack for my Kenmore oven model #326B1229P003 and ordered a pair from another site that said "about 23x17 inches"

Well, the current racks I have are 22.5 by 16.5 inches and these are just about a quarter inch short on all sides of that, but they fit in the oven safely and don't wobble around so I'm happy.
