Frigidaire upright freezer models come in capacities of 12.8 to 20.5 cubic feet, and chest freezer models are available in capacities of 5 to 21.5 cubic feet, as of 2015. Frigidaire also offers models that convert from freezer to refrigerator, and those units range from 16.6 to 20.5 cubic feet.
The larger upright models include adjustable shelves and door bins, pull-out baskets, digital temperature displays and high-temperature alarms. Frigidaire's large chest freezers come with removable sliding baskets and keyed door locks. Each cubic foot of freezer space holds about 35 pounds of food, and Lowe's recommends at least 2.5 cubic feet of freezer space per family member. Larger models are for families who preserve garden produce or who purchase bulk groceries.
