Convection oven racks are typically the same as standard oven racks, and manufacturers often make similar ovens both with and without convection functionality. Oven racks are designed to take up as little space as possible, which is desirable in both oven types.
The convection fan in most convection ovens can often be turned off, which transforms the oven into a standard oven. One of the advantages of convection ovens is the consistent heating throughout the unit. In traditional ovens, rack placement can have a dramatic impact on how long meals take to bake and whether the food is burned. In convection ovens, rack placement has little impact.
