A standard stackable washer and dryer measures 27 inches wide, 74 to 80 inches tall, and 30 to 34 inches deep once stacked. Those are the cabinet numbers. The installed numbers run bigger: about 29 inches of finished width, 38 to 41 inches of depth in an enclosed closet, 20 inches of clear floor in front for the doors, and a ceiling that clears the stack with working room to spare. This guide runs the full fit math, because the box dimensions are only the start.
What are stackable washer and dryer dimensions?
Stackable washer and dryer dimensions describe the combined size of a front-load washer with a dryer mounted on top using a stacking kit. A full-size stacked pair measures about 27 inches wide, 74 to 80 inches tall, and 30 to 34 inches deep. Compact stacked pairs run about 24 inches wide, 66 to 72 inches tall, and 22 to 29 inches deep. This page covers pair configurations only; single-machine numbers live on our washing machine dimensions hub.
Stackable washer and dryer dimensions chart
Every row below is cabinet dimensions, in inches, without hoses, vents, or door swing. The installed footprint always runs bigger, and the sections after the chart run that math.
| Pair configuration | Width | Height | Depth (cabinet) |
|---|---|---|---|
| Full-size stacked (two machines + kit) | 27 in | 74 to 80 in | 30 to 34 in |
| Laundry center (single cabinet) | 27 in | 74 to 77 in | 30 to 33 in |
| Compact stacked (two machines + kit) | 24 in | 66 to 72 in | 22 to 29 in |
| Side-by-side pair (two machines) | 54 in | 39 to 44 in | 27 to 34 in |
Where the stacked height comes from
The 74 to 80 inch range is not a guess. It is two machine heights plus the stacking kit, and you can check it against real models:
- A standard front-load washer is 39 inches tall; a matching dryer is about 36 inches; the stacking kit adds roughly 2 inches. 39 + 36 + 2 = 77 inches, dead center of the range.
- LG’s WashTower, a single integrated cabinet, specs at 27 wide by 74.38 tall by 30.38 deep.
- GE’s Spacemaker laundry center specs at 27 wide by 75.5 tall by 30.81 deep.
- A Frigidaire laundry center lists 27 wide by 77 tall by 32 deep; a Samsung washer-dryer stacked with its kit totals 77.5 inches.
So when a retailer lists a stacked pair at “75 inches” or “80 inches,” both are inside the normal band. The exact number is a property of the model, not a standard, which is why the chart carries the range and the fit math below plans for the worst case, 80 inches.
Side-by-side pair width math
Two full-size machines side by side are 27 + 27 = 54 inches of cabinet. The installed width is bigger:
- One inch between the machines, which Whirlpool specifies for side-by-side installs.
- One inch of air on each outer side for circulation and vibration, per the standard clearance rule.
54 + 1 + 1 + 1 = 57 inches of finished width. A standard 60-inch laundry alcove therefore fits a side-by-side pair with 3 inches to spare. If your alcove is exactly 54 inches, the cabinets fit and the clearances do not; expect more vibration noise and harder servicing.
The closet-fit math (the part nobody publishes)
A stacked pair looks like a closet appliance, but a standard 24-inch-deep reach-in closet cannot hold one. Here is the subtraction, using a typical 32-inch-deep full-size stack:
- Cabinet depth: 32 inches
- Hoses and dryer vent behind: 4 to 6 inches (vented dryers need the full amount; a kinked vent overheats the dryer)
- Working margin so the unit slides in and out for service: 1 to 3 inches
32 + 6 + 3 = 41 inches of enclosed depth for a comfortable install. Samsung’s own installation guidance specifies approximately 41 inches of depth for enclosed closet installs, which lands on the same number from the manufacturer side.
Now the fit test, direction by direction, for a 27-wide by 77-tall by 32-deep stack:
- Width: 27 + 1 + 1 = 29 inches minimum. A 30-inch-wide closet fits with one inch per side; tighter than that is a vibration problem.
- Depth: 32 + 6 = 38 inches minimum, 41 ideal. A 24-inch-deep reach-in fails this test by 8 to 17 inches: the cabinet sticks out past the closet frame by roughly 8 inches before you connect a single hose. A ventless (condenser or heat pump) dryer saves about 3 to 4 inches of rear depth, but it does not close an 8-inch gap.
- Height: 77 inches of stack plus 6 inches of working headroom for lifting the dryer into place, per Samsung’s installation clearance. 83 inches, which a standard 96-inch (8-foot) ceiling clears comfortably.
The diagram below draws this envelope to scale, including the 24-inch closet the cabinet overflows.
The honest closet answer: a full-size stacked pair wants a purpose-built laundry closet at least 29 inches wide, 38 to 41 inches deep, and 83 inches of clear height. A 24-inch-deep reach-in is a compact-stacked job (24 wide by 66 to 72 tall by 22 to 29 deep), not a full-size one. Our reach-in closet dimensions guide covers how that 24-inch standard is measured, if you want to double-check your own.
The clearances that actually matter
| Clearance | Rule | Why |
|---|---|---|
| Sides | 1 in each side | Air circulation; stops vibration transferring into walls |
| Behind (vented) | 4 to 6 in | Water hoses, drain line, and dryer vent need gentle bends, not kinks |
| Behind (ventless) | 2 to 3 in | No exhaust duct; saves 3 to 4 in of depth against a vented unit |
| Top | 1 to 3 in working; 6 in install headroom | Airflow, plus room to lift the dryer onto the washer at install |
| Front | 20 in minimum | Both doors (washer and dryer) swing out for loading |
| Door-open total | ~55 in from the wall | 30.38 in cabinet + 4 in hoses + 20 in door, per LG’s 90-degree door-open spec |
Keep 20 inches of clear floor in front of the stack for the doors. That zone cannot hold a laundry basket permanently, and in a narrow hallway it can block the walking path while you load.
Installation heights and the reach problem
Stacking trades floor space for height, and the height has a daily cost: the dryer controls end up near the ceiling. Measured on a real Samsung stacked set, the dryer buttons sit about 72.5 inches off the floor with the power button at about 74.5; independent guides put the typical control band at 68 to 72 inches. Ergonomics research puts comfortable upward reach at 60 to 65 inches. If you are under about 5 foot 5, expect a step stool for every load.
Three things that fix it:
- Center-control towers. LG’s WashTower and Samsung’s integrated laundry centers put both control panels in the middle of the unit, at chest height, instead of at the top. If reach is a concern, this is the buying criterion that matters most.
- A lower stack. Compact stacked pairs top out at 66 to 72 inches, which drops the dryer controls proportionally.
- Side by side. The controls stay at 39 to 44 inches. If you have the 57 inches of width, the ergonomic problem never appears.
Two more height checks before you buy. First, the water shutoff valves and the 240-volt dryer outlet sit behind the stack; with an 80-inch stack under a 7-foot (84-inch) ceiling, only about 4 inches of working room remains above the unit, so confirm you can reach the connections before the machines go in. Second, only front-load washers stack; top-load washers cannot take a dryer on top, and no stacking kit changes that.
Pedestals: the rule everyone asks about
Can you put the washer on a pedestal and stack the dryer on top? No, and this one is not a guideline. LG’s pedestal installation manual states: “A stacked washer/dryer pair should never be mounted on a pedestal.” Appliance specialists add that it makes the tower unstable in the spin cycle and usually voids the manufacturer warranty. A stacking kit is designed to connect the dryer directly to the washer; a pedestal is designed to raise one machine for side-by-side layouts.
The pedestal math is still useful for side-by-side pairs: a 39-inch washer on LG’s 13.9-inch pedestal totals 52.9 inches, call it 53. Just never put a dryer above it.
Delivery path for a stacked pair
A stacked pair arrives as two separate boxes, each about 27 inches wide, or as one integrated cabinet (laundry centers like the WashTower ship as a single 27-inch-wide unit). Either way the narrowest point on the route decides. LG’s installation guidance calls for a minimum 30 inches of clear width through stairs and doorways, and a 27-inch-wide machine passes a 30-inch door with about 3 inches to spare. Measure jamb to jamb, remove doors that intrude into the opening, and check the turns: a machine that fits a straight hallway can still get stuck pivoting into the laundry room. Our guide on how to measure furniture for doorways covers the full route method, and the same pivot geometry applies to a washer box.
Stacking kit rules
- The washer goes on the bottom, always. It is heavier and it vibrates; the dryer rides on top.
- Washer and dryer should be the same brand and series so the dryer’s feet line up with the kit’s mounting points.
- Buy the manufacturer’s kit for your models, not a generic one. Kit thickness and screw alignment are model-specific, and a wrong kit is a stability risk at 1,200-plus RPM spin speeds.
- Have a second person or a pro for the lift. A dryer at chest height over a washer is a two-person job, and dropping it turns a thousand-dollar appliance into scrap.
Frequently asked questions
Can I stack any washer and dryer?
No. Only front-load washers are designed for stacking, and only with the matching manufacturer’s stacking kit for the same brand and series. Top-load washers cannot support a dryer on top. Laundry centers skip the question entirely: they ship as one pre-stacked cabinet.
Will a stackable washer and dryer fit in a standard 24-inch-deep closet?
No, not a full-size one. A 32-inch-deep stack needs 38 to 41 inches of enclosed depth once hoses and the dryer vent are connected, so it overflows a 24-inch reach-in by roughly 8 inches. A compact stacked pair (24 wide, 22 to 29 deep) or a purpose-built laundry closet is the fix.
How tall a ceiling do I need for a stacked washer and dryer?
Plan for the stack plus 6 inches of install headroom: about 83 inches for a 77-inch stack, more if your model runs to 80. A standard 8-foot (96-inch) ceiling clears any full-size stack comfortably; a 7-foot ceiling with an 80-inch stack leaves only about 4 inches of working room above the unit.
Can I put a stacked washer and dryer on a pedestal?
No. LG’s pedestal installation guide explicitly warns that a stacked washer and dryer pair should never be mounted on a pedestal, and stacking on one risks instability and voids the warranty. Pedestals are for side-by-side layouts only.
Will a stacked washer and dryer fit through a 30-inch door?
Yes. Each machine (or the single integrated cabinet) is about 27 inches wide and passes a 30-inch doorway with about 3 inches to spare. Measure the actual clear opening jamb to jamb, and remove the door slab if it intrudes into the opening.
What is the difference between a laundry center and a stacked washer and dryer?
A laundry center is one pre-assembled cabinet with the dryer permanently mounted above the washer and a single control panel, typically 27 wide by 74 to 77 tall. A stacked pair is two separate machines joined by a stacking kit, 27 wide by 74 to 80 tall, which you can unstack for service or replace one half at a time.
