A:Answer Hi there, thanks for asking! For any size oven, the food item should have a minimum of one inch air space on all sides: top, bottom, right, left and back wall. 24-26 lbs. is usually the largest size turkey available for purchase. A normal bird size is 22-23 lbs. The pan size needed to accommodate the turkey may restrict sizing. Larger sized turkeys are baked on the lowest rack position in range/oven. - A 30" Freestanding Double Oven Range (and most 2017 and newer Slide-in Ranges) the lower oven will hold a turkey about 20 lbs. - The turkeys we test are normally in the 20-25lb range, and in those cases we use the lower oven of the double oven. We do not have any information on turkey sizes for the upper oven, nor do we recommend cooking whole turkeys/chickens/hams in the upper oven. - For availability, we'd reach out to Best Buy as they would be the best source of information regarding that. Hope this helps! Stay safe. -Michael@Cafe
