The standard width of a washing machine is 60 cm, and the height is 85 cm. This generally applies to front loaders; washing machines that have your door on the front of the drum. Top-loading washing machines, which have the opening on the top of the drum, are generally a lot narrower and a little higher. Top loaders usually have a width of 40 cm and a height of 90 cm. Because of this, the drum of a top-loading washing machine is smaller, which means it can hold less laundry per wash.
