Washer and Dryer Space: Stacked and Side-by-Side Closet Sizes

How much space a washer and dryer need

Machine dimensions alone undersell the space. The table adds the clearances that installation guides ask for: about 1 in on each side, 4 to 6 in behind for hoses and the dryer vent, and 1 in or more above. Machine sizes themselves are in the washing machine dimensions chart.

Minimum laundry space by arrangement (inside width × depth × height)
Arrangement	Width	Depth	Height
Side by side, full-size front-load	56 to 60 in 142 to 152 cm	35 to 40 in 89 to 102 cm	41 in; 50 to 56 in on pedestals
Side by side, top-load washer + dryer	57 to 60 in 145 to 152 cm	31 to 36 in 79 to 91 cm	Lid open: about 54 to 60 in
Stacked, full-size front-load	28 to 30 in 71 to 76 cm	35 to 40 in 89 to 102 cm	81 in 206 cm or more
Stacked, 24 in compact	25 to 26 in 64 to 66 cm	30 to 32 in 76 to 81 cm	68 to 70 in 173 to 178 cm
Laundry center (one unit)	25 to 28 in	32 to 36 in	72 to 78 in
Under a counter, compact	25 in per machine	26 to 30 in	Counter underside 34.5 in

Wall space taken by the three common arrangements, including side and top clearances, drawn to scale.

In front of the machines, keep at least 42 in (107 cm) clear. A front-load door swings about 22 in, and you need to stand and bend in front of it with a basket. That makes a walk-in laundry room with machines on one wall at least 82 in (about 7 ft, 208 cm) deep.

Stacked washer and dryer dimensions

Stacking is the usual answer when the floor space is under 56 in wide. It works only with a front-load washer and a front-load dryer of the same width, usually of the same brand, joined with the maker's stacking kit.

Full-size (27 in): each machine is 38 to 39.75 in tall, so the stack is about 76 to 80 in (193 to 203 cm). The dryer controls end up at 74 to 79 in, and the lint filter on many models is at the top of the door opening. Shorter users may need a step stool.
Compact (24 in): each machine is about 33.5 in tall, so the stack is 67 to 68 in (170 to 173 cm), and the dryer controls stay within reach for most adults.
Laundry centers: a single cabinet with a small top-load washer below and a dryer above, 24 or 27 in wide and roughly 71 to 77 in tall. Drum capacities are smaller than separate full-size machines.

Pedestals cannot go under a stack, and the dryer cannot go on the bottom. Check the depths match too: a dryer 2 in deeper than the washer below it overhangs at the front or back.

Closet doors and ventilation

Bifold and sliding closet doors take 1 to 4 in of depth, so measure from the back wall to the inside of the closed door, not to the frame. A dryer in a closet also needs make-up air: Whirlpool-group installation instructions, for example, call for door openings of at least 48 sq in near the top and 24 sq in near the bottom (a louvered door usually provides this). Gas dryers have stricter rules, so follow the dryer's own guide.

Side-by-side layouts and door swing

Two 27 in machines are 54 in wide together. With 1 in between them and about 1 in at each wall, the opening needs 56 in; 60 in leaves space to slide them out for service without scraping the walls.

Door direction: put the washer door's hinge on the side away from the dryer and the dryer door's hinge away from the washer. Both doors then open outward and the gap in the middle is free for moving wet laundry across. Most dryer doors and some washer doors can be reversed.
Pedestals: 10 to 15 in drawers raise the openings to a more comfortable loading height but make the pair 50 to 55 in tall, which blocks a 36 in counter or shelf above.
Counter over the pair: a worktop above full-size front-loaders must have its underside at about 40.5 in or higher, so the top sits near 42 in. A standard 36 in kitchen counter only clears 24 in compact machines.

Hookups and where to put them

Getting the services in the right place matters as much as the floor space, because hoses and the vent set how close the machines can sit to the wall.

Washer and dryer connections
Connection	Standard	Notes
Water supply	Hot and cold valves with 3/4 in hose threads	Usually in a recessed outlet box on the wall behind the washer
Drain standpipe	2 in pipe, 18 to 42 in above the trap weir (IRC P2706.2)	A front-loader pumps up to the standpipe, so it can be higher than the drum
Washer power	120 V outlet on a 20 A laundry circuit (NEC 210.11(C)(2))	Most compacts and all full-size washers use 120 V
Electric dryer	240 V, 30 A, 4-prong NEMA 14-30 outlet	Older homes may have a 3-prong 10-30; the dryer's cord must match
Gas dryer	Gas shutoff valve plus 120 V outlet	Natural gas or propane, matched to the dryer's burner
Dryer vent	4 in rigid metal duct, 35 ft maximum (IRC), less for each elbow	Ventless condenser and heat pump dryers need no duct

Place the outlet box and electrical outlets above the top of the machines or to one side, not directly behind them, so you can shut off the water without pulling a 200 lb washer out. For a stacked pair, keep them within reach at roughly 42 to 48 in from the floor beside the stack. Vent lengths and elbow deductions are covered in detail in the dryer dimensions guide.

Getting the machines in: delivery path

A washer that fits the closet is no use if it cannot get there. Check every point on the route.

Find the machine's narrowest side. For a full-size washer that is the 27 in width; depth is 30 to 34 in. Add about 1 in for hands and a dolly.
Measure door clear openings, not door sizes. The clear width is about 2 in less than the door slab. A 30 in door gives about 28 in clear, which passes a 27 in machine. A 28 in door gives about 26 in and does not, unless the door is taken off its hinges. See the door size guide for standard slabs.
Check turns. In a hallway, the corner has to clear the machine's diagonal. A 27 × 32 in washer has a 41.9 in diagonal, so tight 36 in halls with a right-angle turn can stop it.
Plan for weight on stairs. Front-loaders weigh about 160 to 230 lb (73 to 104 kg), dryers 100 to 150 lb. Delivery crews may refuse narrow or winding stairs, so mention them when you book.
Leave room to install. The machine has to be pushed in from the front, hooked up from the side or front, and leveled. In a 56 in alcove you will connect the hoses before sliding it the last 6 in.

Machine capacity for your household

A larger drum means fewer loads, but every extra cubic foot adds depth. Match the washer to the household first, then pair a dryer about 1.6 to 1.8 times its volume so the load can tumble freely.

Washer and dryer capacity by household size
Household	Washer	Matching dryer	Practical format
1 to 2 people	2.2 to 2.6 cu ft (6 to 7 kg)	4.0 to 4.5 cu ft	24 in compact, stacked or under a counter
2 to 3 people	3.5 to 4.0 cu ft (7 to 8 kg)	6.5 to 7.0 cu ft	27 in, side by side or stacked
3 to 4 people	4.5 cu ft (8 to 9 kg)	7.3 to 7.5 cu ft	27 in, the most common pairing
5 or more	5.0 cu ft or more (10 kg or more)	7.8 to 9.0 cu ft	27 in large-capacity, about 32 to 34 in deep

The large-capacity row is where planning catches people out: 5 cu ft front-loaders are 2 to 3 in deeper than 4.5 cu ft models, and that extra depth plus hoses can push the front past a closet door frame. Hamper and basket sizes to go with the machines are in the laundry basket guide, and shelving above the pair is covered in the closet organizer sizes.

Accessible laundry layouts

Door opening height: ICC A117.1 and the ADA Standards put the bottom of a front-loader's door opening between 15 and 36 in (38 to 91 cm) above the floor for an accessible machine. A pedestal raises a standard front-loader comfortably into that range and saves bending for everyone.
Clear floor space: ICC A117.1 calls for a 30 × 48 in (76 × 122 cm) clear floor area in front of accessible washers and dryers, for a parallel approach to top-loaders or a forward approach to front-loaders.
Controls on the front panel are easier to reach than those on a top-loader's rear console, which sits at the full 42 to 45 in height and behind the lid.

For counter heights, aisle widths and other room-wide figures, see the kitchen dimensions overview.

Frequently asked questions

How big does a laundry closet need to be for a washer and dryer?

For side-by-side full-size machines, about 56 to 60 in wide and 40 in deep inside the closet, with doors that open the full width. For a stacked pair, 28 to 30 in wide, 40 in deep and at least 81 in tall. Compact 24 in machines stacked need about 25 to 26 in wide, 30 to 32 in deep and 68 in tall.

How tall is a stacked washer and dryer?

Two full-size front-loaders stacked with a kit are about 76 to 80 in (193 to 203 cm) tall. A stacked 24 in compact pair is about 67 to 68 in (170 to 173 cm). Single-unit laundry centers, with a top-load washer below and a dryer above, are roughly 71 to 77 in tall.

Can you stack a dryer on a top-load washer?

No. Stacking kits only work with front-load washers, because a top-loader's lid has to open upward. If you need one column, buy a front-load pair of the same brand and width or a single laundry center unit.

What size door does a washing machine fit through?

A 27 in washer needs a clear opening of at least 28 in, which a standard 30 in (2 ft 6 in) interior door just provides. A 28 in door leaves only about 26 in clear, so the door has to come off its hinges or the machine has to go in another way. Compact 24 in machines fit through a 28 in door.

How much space do you need behind a washer and dryer?

Plan 4 to 6 in (10 to 15 cm) behind the washer for the supply hoses and drain hose, and about 5 to 6 in behind a vented dryer for the duct elbow. A slim periscope vent or a ventless dryer cuts that to 1 to 3 in. The exact minimums are printed in each machine's installation guide.
