I discovered that my biggest cookie pans and the half-sheet baking pan won’t fit in the new, double, wall oven I bought. It’s only 27” wide. But 10 x 15 and 12 x 16 pans fit just fine, so I can do three sheets of cookies at once. Both sections of the oven are regular and convection, so I’m looking forward to doing some baking in it.
And supposedly with the convection ovens, you can use every rack without difficulty, because the heat is even throughout the oven. No shuffling trays around in order to deal with some parts of the oven being hotter than others.
Should work well for cookies! I have room and racks for two trays...not bad.
