what size washer is standard?
In addition to a washer's external dimensions, you will also want to think about size of the washing drum inside the unit. Excluding compact units, most of which have a drum somewhere in the 2-cubic-foot range, the majority of standard-size front- and top-load washer drums today range from roughly 4 to 5 cubic feet. That's a great range for a typical 8-pound load.
