Stackable Washer and Dryer Dimensions

A stacked washer and dryer keeps a full-size laundry pair in the footprint of a single machine — about 27″ wide, with the dryer bolted on top of the washer. The number that decides the install isn’t the width, it’s the stacked height: plan for 74–80″ floor-to-top once the units and the stacking kit are combined.

Standard stacked dimensions

Two front-load machines plus a stacking bracket. Width and depth are a single unit’s; height is both, added together.

Dimension	Full-size (27″)	Compact (24″)
Width	27″	24″
Depth (body)	31–34″	24–26″
Each unit height	38–39″	33–34″
Stacked height	74–80″	67–70″

Depth is the sneaky one: the 31–34″ body grows by roughly 6″ once you add the dryer vent elbow and water hookups behind, so plan for the unit to sit about 31–34″ off the wall and budget door-open clearance of 50–55″ in front.

Can you stack any washer and dryer?

No — three rules decide it:

Front-load only. A top-load washer opens upward, so nothing can sit on it. Both machines must be front-loaders.
Matching width and brand. The dryer has to be the same width as the washer (27″ on 27″), and in practice the same brand/series so the stacking kit fits.
A stacking kit is required. It’s a model-specific bracket that locks the dryer to the washer — never stack without one. The kit can add up to ~1¼″ to the combined height.

Measure the stacked height against the ceiling

Before buying, check floor-to-ceiling (or floor-to-cabinet) against the 74–80″ stacked height plus the room to lift the dryer onto the washer during install. A low closet shelf is the most common reason a stack won’t go in.

The laundry-closet clearances that bite

A 27″ pair needs more than a 27″ closet. Plan for:

Width: a 30–33″ opening so the machine slides in with a finger-gap each side.
Depth: 31–34″ for the body, vent and hoses — plus the door swing if the closet has doors.
Venting: the dryer still needs a vent run behind it; a ventless heat-pump or condenser dryer removes that, at the cost of longer cycles.

Stacked pair vs. a laundry center

They look similar but aren’t the same. A stacked pair is two separate full-size machines joined by a kit — full capacity, taller (74–80″). A laundry center (unitized) is one welded appliance with the dryer permanently above the washer — shorter (about 74–76″) and narrower (24 or 27″), but with smaller drums. Choose the laundry center for the tightest spaces, the stacked pair for capacity.

Frequently asked

How tall is a stacked washer and dryer?

About 74–80″ for a full-size 27″ pair, and 67–70″ for a compact 24″ pair — measured floor to the top of the dryer with the stacking kit installed.

How wide is a stackable washer and dryer?

27″ for full-size machines and 24″ for compact. The dryer must match the washer’s width to stack.

Can you stack any washer and dryer?

Only front-loaders of matching width, almost always the same brand, and only with the manufacturer’s stacking kit. Top-load washers can’t be stacked.

Do you need a stacking kit?

Yes. The kit is a model-specific bracket that secures the dryer to the washer so it can’t walk off during the spin cycle. Stacking without one is unsafe.

What size closet do I need for a stacked unit?

Plan a 30–33″ wide opening and 31–34″ of depth for the body, hoses and vent — more than the 27″ machine width alone.
