A full-size stackable washer & dryer is about 27 inches wide, 30 to 34 inches deep and 74 to 79 inches tall when stacked. Compact sets are about 24 inches wide and 66 to 72 inches tall.
This guide covers stackable washer & dryer dimensions, space and clearance needs, the smallest sizes, and how stackables differ from laundry centers and combos.
Whirlpool’s sizing guide and other maker specs show clear patterns. Here are the typical stacked washer dryer dimensions by type.
Type
Width
Depth
Stacked height
Full-size stackable pair
27 in (69 cm)
30–34 in (76–86 cm)
74–79 in (188–201 cm)
Stacked laundry center
23–28 in (58–71 cm)
26–33 in (66–84 cm)
about 75 in (190 cm)
Compact stack
about 24 in (61 cm)
24–26 in (61–66 cm)
66–72 in (168–183 cm)
Sizes vary by brand and model, so always check the spec sheet.
How Tall Is Each Machine?
A front-load washer or dryer stands about 39 inches (99 cm) tall. Stack two and you get roughly 78 inches (198 cm). A stacking kit and control panel can add a little more.
Side by side, the same pair measures about 54 inches (137 cm) wide. Stacking cuts the floor space nearly in half.
Stacked Laundry Center Dimensions
A laundry center is one permanent unit. Whirlpool lists a 27-inch stacked laundry center at about 75½ inches tall and 27¼ inches wide. Most centers pair a top-load washer with a dryer on top.
Washer and Dryer Capacity
Standard washers hold about 3 to 5 cubic feet. Dryers hold about 5 to 7 cubic feet. Large-capacity washers start near 4.5 cubic feet, and large dryers go past 7.

Stackable Washer Dryer Space and Clearance Requirements
The machine’s size is only part of the answer. You also need room around it.
How Much Space Do You Need?
Use these stackable washer dryer clearance rules as a starting point:
Behind: Leave about 6 inches for hoses, vents and plugs.
Sides: Leave about 1 inch on each side for airflow.
Front: Leave about 4 feet so a front-load door can open and you can load laundry.
Above: Leave a few inches of headroom. Guides range from about 1 to 6 inches, so follow your model’s installation guide.
For a typical front-load set, Whirlpool suggests a space about 29 inches wide, 80 inches tall and 32 to 34 inches deep. That is roughly 74 × 203 × 86 cm.
Will It Fit My Closet?
Measure first, then match the stack. This is a simple rule of thumb.
Your closet
What usually fits
Height under 76 in
Compact stack only
Height 76–83 in
Compact stack or laundry center
Height 83 in or more
Any type, including a full-size pair
Depth under 30 in
Compact stack only
Bifold doors need extra thought. Make sure the folded leaves have somewhere to go.
How to Measure for a Stackable Washer and Dryer
Measure height from the floor to the ceiling or the lowest shelf.
Measure width from wall to wall.
Measure depth from the back wall to the closed door.
Check doorways and halls along the delivery path.
Add the clearances above.
Hookups and Venting
Electric dryers usually need a 240-volt outlet. The washer needs a standard outlet, hot and cold water lines and a drain. A vented dryer also needs an exterior vent. A ventless dryer does not.
Pedestals and Extra Height
A pedestal adds about 10 to 16 inches. Count that height if you add one.

Tight on space? Compact options go small.
How Small Can a Stackable Washer and Dryer Be?
Whirlpool lists a compact stackable set at about 24 inches wide, 66 to 72 inches tall and 24 to 26 inches deep. Some narrow laundry centers come in just under 24 inches wide.
Smallest Washer and Dryer Sizes
Option
Typical size
Compact washer or dryer
24 in wide, 33–36 in tall, 24–26 in deep
Compact stack
24 in wide, 66–72 in tall, 24–26 in deep
All-in-one washer dryer
23–27 in wide, 33–39 in tall, 22–30 in deep
All-in-one units hold about 2 to 4 cubic feet.
Trade-Offs of Going Small
Small machines hold smaller loads, so you may run more cycles. They suit apartments, condos, closets and RVs.

Can You Stack a Top-Load Washer?
Not as a separate pair. Only front-load washers are built to stack. A top-load washer works in a laundry center, where the maker designed the unit as one piece.
Downsides of a Stackable Washer and Dryer
Height: You need enough ceiling space.
Reach: The top machine’s controls sit high.
Stacking kit: You must use the matching kit for safety.
Laundry centers: You can’t separate or replace one half on its own.
Compact models: Loads are smaller.
Combo vs Stackable
A combo washes and dries in one drum. A ventless drying cycle can take longer, so Whirlpool suggests loading items loosely. A stackable set runs both jobs at the same time.
