Washing Machine Dimensions: Standard Sizes by Type

There is no true industry standard, so each type is given as a range. The 27-inch width is a long-standing convention rather than a rule, and widths now run from 27 to 30 inches as makers chase larger drums.

The depth column is the cabinet alone. It leaves out the hoses, the vent and the plug behind the machine, and it leaves out a front door that stands open.

The US laundry category settled on a 27-inch width decades ago, and the number stuck because cabinets, closets and dryer pairs were built around it. The European machine is a different product: it is built to a cabinet about 23.6 inches (600 mm) wide, designed to slide under a kitchen counter. A page quoting 23.6 inches (60 cm) is describing a machine that is not sold in the US in that form, so its numbers do not transfer.

Width has also crept upward. A high-capacity washer can now be 28, 29 or 30 inches wide, because a wider drum holds more clothes. An opening that took a 27-inch machine ten years ago may not take its replacement, so measure the opening rather than trusting the old machine's size.

A washer that matches the opening on paper can still fail on one of four measurements. Take all four before you shop.

• Width of the opening, measured at its narrowest point, baseboards and trim included.
• Depth plus about 6 inches behind the machine for hoses, the vent and the plug. The listed depth excludes them.
• Height plus the swing: 20 to 24 inches of clear space above a top loader for the lid, and a front-loader door that projects roughly 22 to 25 inches when open.
• The path in: doorways and hallways at least 30 inches at the narrowest point, and about 43 inches to clear a 90-degree turn. Measure with knobs, closers and screen doors in place.

Plan on about 1 inch on each side and between the washer and dryer, about 6 inches behind, and 20 to 24 inches above a top loader. A front loader wants roughly 4 feet of clear floor in front of it so the door can open and you can stand with a basket.

Some installations require a drain pan under the machine, and the pan adds to the height you need to allow for. A front loader's open door needs room to swing, so a tight closet can rule one out even when the cabinet itself fits.

Work through these steps in this order, because each one can rule out a machine before you get to the next.

1. Measure the opening at its narrowest point, including baseboards and trim.
2. Measure the interior depth and add 6 inches for hoses, vent and plug.
3. Check the height, then the lid or door swing above and in front.
4. Check the hookups: water supply, drain, power and, for a dryer, the vent.
5. Walk the delivery path and measure every doorway and turn on it.
6. Check the floor for level and for whether a drain pan is required.

A top-load opening no higher than 36 inches above the finished floor keeps the drum reachable, and a front-load door whose opening sits between 15 and 36 inches above the floor lets you load without stooping or stretching. Controls should be reachable with one hand and light effort.

Deeper high-efficiency top loaders make the bottom of the drum harder to reach, which matters for shorter users. That is a reach trade-off against capacity, and it is worth checking with the lid open before you commit to a large drum.
