The type of freezer to purchase will depend on family size, whether fresh produce or large quantities of meat will be frozen, available floor space, and efficiency and defrosting features preferred. The standard capacity of a freezer is about 35 pounds of frozen food per cubic foot of useable space. Families that freeze garden produce should allow six cubic feet of freezer space per person. If other methods of food preservation are used, allow three cubic feet per person.
Additional space is needed if large amounts of meat are kept in the freezer.
They also maintain higher quality food than frostless models because they don't have a fan running to remove the moisture that would turn to frost. The constant removal of moisture from the freezer could cause freezer burn in improperly wrapped food. Frost-free chest freezers are not available, but frost builds up in them less readily. They have one or two outside doors and from three to seven shelves for storing food. Freezers of this type are popular due to their convenience, the small floor space they require and the ease with which food may be put in or removed.
