How big washing machine do I need?
Generally speaking, 4 cubic feet is enough to wash 12-16 pounds of laundry. A larger capacity unit at 4. 5 cubic feet can hold up to 20 pounds of laundry. A general rule of thumb is a queen size comforter can fit into 3. 5 cubic feet and a king size comforter fit into a 3. 8 cubic feet machine.
