Finding the right accessories to fit your individual air fryer often seems to be a problem, no matter where you buy the fryer unit itself. These measurements are for the Bellagione 8-piece accessory set only. They fit my QVC Cook's Essentials 3.4 quart air fryer that was a Today's Special toward the end of January perfectly, and should fit most units in the same size range, measure carefully to be sure. That particular Cook's Essentials has a removable basket with a 7 3/4 inch maximum inside diameter and includes a cake pan with handle, pie pan and problematic recipe booklet. Don't depend on their booklet, get a cookbook or look for recipes online if you're new to air frying.Cake pan - 7 1/2 inches including the "ears" where the handle is attached. I'd recommend folding a few layers of aluminum foil over those ears or they might scratch the basket if the pan moves a bit during cooking. It's about 1/2 inch bigger than the pan that comes with the QVC unit.Pie / pizza pan - 7 inches outside, 6-inch inside diameter, about 1/2 inch bigger than the Q's panThe metal racks, silicon trivet and small tools aren't included with the QVC set and make a nice addition although the "pot lifter" might not be very practical. The more basic wire rack is about 6 3/4 inches in diameter, the other one with the 3-skewer holder is about 7 1/8 inches and the 3 skewers are 7 inches long. They can't really be stacked to make 2 cooking levels unless you turn the basic rack upside down so don't plan on using them that way. Both racks fit the 3.4 quart QVC fryer very well. Just from comparing what's online, it seems the 3-skewer racks usually fits baskets between 7 and 8 inches and the 4-skewer racks in some other sets fit the bigger 5-quart-plus units but that's just a guess, don't hold me to it.So far everything fits my fryer and it seems like a nice set. Hope my good luck holds.
