Upright freezers typically have smaller capacities than chest freezers of the same size because storage space is lost to shelving. Some chest freezers include dividers, but the partitions are removable, allowing users to fill all the available space.
Because chest freezers are wide rather than tall, they require more floor space than upright units. Even though upright freezers provide less storage capacity than chest freezers, they usually are more expensive because they provide shelves on the inside and bins in the door. Some upright freezers offer a frost-free option for an additional cost, but most chest freezers are available only with manual defrost.
