Stackable Washer and Dryer Dimensions: Will a Stack Fit Your Space?
Last updated October 31, 2026
A full-size stacked pair measures about 27 inches wide, 74 to 80 inches tall and 30 to 34 inches deep. A compact stacked pair measures about 24 inches wide, 66 to 72 inches tall and 22 to 29 inches deep. The room you actually need is bigger: plan on roughly 29 inches wide, 38 to 41 inches deep and 83 inches tall once hoses, vent, service space and the headroom to lift the dryer are counted.
Width is effectively standardized at 27 inches for full-size front-loaders, so a 30-inch opening fits nearly any full-size stack and a 26-inch opening fits almost none.
The measurements that decide if a stack fits
Width is effectively standardized at 27 inches for full-size front-loaders, so a 30-inch opening fits nearly any full-size stack and a 26-inch opening fits almost none. The real alternative for a narrow spot is the 24-inch compact class, at roughly half the capacity.
| Configuration | Width | Height (stacked) | Depth (body) |
|---|---|---|---|
| Full-size stacked pair (front-load washer + dryer + kit) | ~27 in | 74–80 in | 30–34 in |
| Compact stacked pair (24-in class) | ~24 in | 66–72 in | 22–29 in |
| Laundry center (unitized tower) | 23–28 in | 52–76 in | 26–35 in |
| All-in-one washer-dryer combo | 23–28 in | 33–47 in | 22–34 in |
| Side-by-side pair (for comparison) | ~54 in | ~39 in | 30–34 in |
A laundry center is usually shorter than a self-stacked pair, which is the deciding fact for a low closet. An all-in-one combo is the shortest of the group because one drum does both jobs.
Where the numbers come from
Stacked height is a sum, not a standard. You add the washer's height, the dryer's height, the stacking kit and a little air.
Full-size front-load washers and dryers cluster around 39 inches tall each. Add a kit of about 1 to 1¼ inches and a small gap, and you get 39 + 39 + 2 ≈ 80 inches. That is why most full-size stacks land between 77 and 80 inches.
Compact units run about 33 to 36 inches each, which gives 66 to 72 inches stacked. The exact figure for any pair is the sum of the two machines' published heights plus the kit, and the pair's installation instructions are the final word.
Cabinet size vs. installed envelope
Your room has to provide the installed envelope: the cabinet plus everything the machine needs around it to run, vent and be serviced.
| Side | Clearance | Why |
|---|---|---|
| Each side | ~1 in | Vibration, door swing, service |
| Rear, vented dryer | 4–6 in | Hose and rigid vent elbow; a flat periscope duct cuts it to ~3 in |
| Rear, ventless dryer | ~2 in | No duct |
| Top | 1–3 in working; ~6 in install headroom | Room to lift the dryer onto the washer |
| Front | 20 in minimum door swing; ~4 ft comfortable | Loading and unloading |
| Closet door | 1 in gap under the door; two air openings totaling ~72 sq in when a dryer shares the closet | Airflow |
The rear clearance is the number most often underestimated, and it is the one that decides closet fit.
Stacking rules
Not every pair can go in a column, and the rules are not negotiable.
- Front-load washers only. A top-load washer cannot be stacked under a dryer.
- Dryer on top. The washer is heavier and vibrates.
- A manufacturer stacking kit is required. It adds about 1 to 1¼ inches to the height.
- Same brand and series in practice. Pairs are designed to stack together.
- Never stack on a pedestal. The column is already tall and top-heavy.
- Stackable pairs can usually be unstacked and used side by side later; a laundry center cannot be separated.
- Two electrical outlets for a stacked pair, one for a laundry center.
Can you reach the dryer once stacked?
On a full-size stack the dryer controls land about 68 to 74 inches off the floor. A comfortable upward reach is about 60 to 65 inches, so users shorter than roughly 5 ft 5 in will want a step stool for the top machine.
Center-control tower designs put the controls at chest height, which is the fix for reach. The trade-off is that a tower is one cabinet you cannot split later.
Vented vs. ventless and the depth math
A vented dryer needs the 4 to 6 inches of rear clearance for the duct. A ventless dryer, heat-pump or condenser, needs only about 2 inches, which can rescue a shallow closet.
Vent runs follow code: a 4-inch smooth metal duct, a maximum run of about 35 ft, minus 5 ft per 90° elbow and 2.5 ft per 45°, terminating outdoors with a backdraft damper and no screen.
A listed condensing (ductless) dryer is exempt from the vent requirement, which is what makes an interior closet with no exterior wall workable. It needs a drain or a water tank to empty.
Measure your space in six numbers
Write these down before you shop, in inches.
- Opening width, jamb to jamb.
- Opening height, floor to header.
- Cabinet depth, back wall to front edge.
- Depth available behind the opening for hoses and vent.
- Front clearance to the nearest wall or door.
- Ceiling height above the install spot.
Then check the delivery path. A 27-inch machine needs a 30-inch door with the slab removed. Measure the narrowest doorway on the route, the stair turns and the hallway width, and take door slabs off before delivery day.
Which of the three fits your measurements
| Format | What it gives you |
|---|---|
| Stackable pair | Tallest of the three when stacked (77–80 in), separable, two outlets, repairable one machine at a time, needs a stacking kit |
| Laundry center | Shorter (52–76 in), one cabinet, one outlet, cannot be separated |
| All-in-one combo | Shortest footprint, one machine does both, no separate dryer, longer cycle times |
A low ceiling points to a laundry center. A shallow closet points to a compact stack or an all-in-one. Wanting to replace machines separately points to a stackable pair.
Keep three sets of numbers in mind: a full-size stack at 27 inches wide, 74 to 80 inches tall and 30 to 34 inches deep, a compact stack at 24 inches wide, 66 to 72 inches tall and 22 to 29 inches deep, and the room to plan for, about 29 inches wide, 38 to 41 inches deep and 83 inches tall. A standard 24-inch-deep reach-in closet will not take a full-size stack, so a compact stack, a laundry center or an all-in-one is the answer there.
The model's installation instructions govern the final fit and the warranty. Read them before you buy, not after delivery.
Frequently asked questions
The rear clearance is the number most often underestimated, and it is the one that decides closet fit.
What are the dimensions of a stackable washer and dryer?
A full-size pair in a column is the standard 27-inch width, and the compact class is 3 inches narrower. Height depends on the two machines you pair: full-size units stack to roughly 6½ feet, compact units to about 5½ to 6 feet. Depth is set by the dryer's venting, from about 2 feet on a ventless compact to nearly 3 feet on a vented full-size pair.
How much room do I need to lift the dryer onto the washer?
Plan on about 6 inches of headroom above the top of the stacked column so you can lift the dryer into place on the kit. The 1 to 3 inches of top clearance that keeps the pair running is not enough for the install itself, so measure floor to ceiling at the spot before delivery day. If the ceiling is lower than that, a laundry center or an all-in-one combo avoids the lift entirely.
How wide is a stackable washer and dryer?
Full-size front-loaders are 27 inches wide almost across the board, so the column is 27 inches plus an inch on each side. Compact units are 24 inches wide, and that 3-inch difference is what lets a compact stack slip into a narrow opening.
How deep is a stacked pair, and how much space goes behind it?
The machines themselves are 30 to 34 inches deep. A vented dryer needs another 4 to 6 inches behind for the hose and vent elbow, or about 3 inches with a flat periscope duct. A ventless dryer needs about 2 inches.
What size closet do I need for a stackable washer and dryer?
The depth is the figure that catches people out, because it includes the hoses and vent behind the machines, not just the cabinet. A standard 24-inch-deep reach-in closet cannot take a full-size pair.
What is the difference in footprint between a stacked pair and a side-by-side pair?
A side-by-side pair takes about 54 inches of width and roughly 39 inches of height, while a stacked full-size pair takes about 27 inches of width and 74 to 80 inches of height. Both are 30 to 34 inches deep at the body. Stacking trades floor width for height, which is why a narrow spot suits a column and a low, wide spot suits two machines on the floor.
What electrical setup does a stacked pair need compared with a laundry center?
A stacked pair of separate machines needs two electrical outlets, one for the washer and one for the dryer. A laundry center runs off a single outlet because the washer and dryer share one cabinet. That extra outlet is part of the space planning, so confirm you have both before the column goes in.
Can you stack a top-load washer and dryer?
No. A top-load washer opens from above, so a dryer cannot sit on it. Stacking starts with a front-load washer, and the dryer is mounted over it with a kit.
Can a stackable pair be unstacked and used side by side?
Usually yes, if the two machines are separate units. Take the dryer off the kit and set both on the floor. A laundry center cannot be split, because the washer and dryer share one welded cabinet.
Can you put a stacked pair on a pedestal?
No. A pedestal adds roughly 10 to 16 inches of height, which pushes the top machine's controls past 80 inches off the floor, well above the 60 to 65 inches a comfortable upward reach covers. Keep the pair on the floor and use a step stool instead.
Do stackable dryers need a vent?
A vented dryer does. A ventless heat-pump or condenser dryer needs no duct at all, but it must drain condensate or have its water tank emptied after every load. A ventless model also needs a drain line or a water tank you empty after each load, and it runs longer, cooler cycles than a vented dryer.
Is a stacked pair taller than a laundry center?
Yes, usually. A self-stacked full-size pair finishes at 77 to 80 inches, while laundry centers run 52 to 76 inches. That gap is why a low closet often ends up with a laundry center instead of a stack.
Will I be able to reach the controls on the dryer once it is stacked?
On a full-size pair the dryer controls end up roughly 68 to 74 inches above the floor, while a comfortable upward reach is only about 60 to 65 inches. If you stand under about 5 ft 5 in, you will need a step stool to operate the upper machine. A center-control tower brings the controls down to chest height, but it comes as a single unit that cannot be separated later.
Will a stacked pair fit through a 30-in door?
Yes, with the door slab removed. A 27-inch machine passes a 30-inch opening once the slab is off its hinges. Measure the full delivery route before you buy, and take door slabs off before delivery day.
What capacity comes with a stackable set?
A full-size pair typically gives about 4.5 cu ft in the washer and 7.4 cu ft in the dryer. The compact class gives about 2.3 cu ft in the washer and 4.1 cu ft in the dryer, which is the price of the smaller footprint.
