2 Standard oven, = 4 racks. Meaning those no shape big flat very big tray.

I think I bought it in Target....one of those not circle, so your entire oven 4 tray, to the tray that is big square. Almost full size of the Oven width. These are not the circle pizza tray.

When you having the guests over, you practically doing nothing but making the food standing there. I finish the first 4 pizza, rectangle /Square, huge, that is entire them eating. Then while they are eating, that is the second batch of the Pizza baking. They just don't bother keep eating the whole day long, the food its on the counter.
