How to Measure Your Laundry Space Before Buying
Laundry appliances fail the fit test more often than any other category, and it’s rarely the width that gets people. It’s the six inches of depth behind the machine that nobody accounts for, and suddenly the bifold closet door won’t close on a washer you already paid for.
Fifteen minutes and a tape measure. Here are the six measurements, in order, and what each one is actually protecting you from.
Measurement 1: Width
Measure between the walls, cabinets, or closet frame at three heights, and use the smallest number. Walls are rarely as straight as they look.
Then subtract about 1 inch per side for vibration clearance. A washer that touches drywall on the spin cycle transmits the vibration into the wall, and the whole house hears it. That clearance isn’t optional, it’s what makes the machine tolerable to live with.
Rough targets: 54–60″ for a side-by-side pair, 27–30″ for a stacked pair or a single machine.
Measurement 2: Depth (the one that ruins deliveries)
Measure from the back wall to the front edge of the space, or to the closed closet door.
Now add 6 inches to the appliance’s spec depth. That’s what the hoses, the electrical connection, and the vent duct need behind the machine. A dryer with a rigid vent elbow can need even more.
So a dryer that’s 31 inches deep on paper needs roughly 37 inches of real space. This single number is the most common reason a laundry closet door won’t shut on a new machine, and it’s completely avoidable.
Measurement 3: Height
Floor to the underside of any shelf, cabinet, or countertop above.
- Side-by-side: 36–40″ is typical. If a counter goes over the top, confirm the washer lid can open fully underneath it (top-loaders need overhead clearance to open, which a counter kills).
- Stacked: you need 75–80″. Critically, check the dryer’s control panel, some stand up at the back and add several inches that the headline spec doesn’t mention.
- Pedestals add 12–15 inches. If you want them, measure for them now.
Measurement 4: Door swing and opening clearance
This is where people create a problem they live with for a decade.
- A front-load washer’s door needs 20–25 inches of clearance in front of it to open fully. In a narrow laundry closet or a tight hallway, that door can hit the opposite wall.
- Check the hinge side, and whether it’s reversible (on washers and dryers, often it is not).
- If the pair sits side by side, check the doors don’t collide with each other. Two front-loaders with doors hinged toward each other is a genuinely annoying discovery.
- A top-load washer needs overhead clearance for the lid, roughly 20 inches above the machine. A shelf or upper cabinet directly above will stop the lid opening.
- The laundry closet door itself. Bifold doors restrict the opening width significantly, and they’re what the machine has to fit through.
Practical test: stand in the space and mime loading a basket of laundry. If it’s awkward in mime, it’s worse in reality.
Measurement 5: The delivery path
Laundry rooms are frequently at the end of the narrowest hallway in the house, behind the tightest turn.
- Front or garage door, including the storm door.
- Every hallway, and especially every 90-degree turn, which is where deliveries die.
- Interior doorways and the laundry closet opening.
- Stairs, low ceilings, and light fixtures.
Measure the narrowest point. If it’s within an inch or two of the machine’s width, tell the store before delivery day so the crew arrives prepared.
Measurement 6: The hookups
Not a measurement exactly, but it belongs on the same trip.
- Gas line? Determines whether a gas dryer is even possible. Gas vs. electric.
- Dryer outlet: electric dryers need 240V, and the plug comes in 3-prong and 4-prong versions that are not interchangeable. Photograph it.
- Hot and cold water valves, and how far they are from where the washer will sit.
- Drain: standpipe or laundry sink, and its height.
- Vent: where is it, and how long and kinked is the run? No vent means a ventless dryer.
The laundry measuring checklist
| Measure | Record | What it prevents |
|---|---|---|
| Width | Smallest of three heights, minus ~1″ per side | A machine that shakes the house |
| Depth | Space depth vs. appliance depth +6″ | A closet door that won’t close |
| Height | Floor to shelf/counter, plus control panel height | A stacked pair that doesn’t fit |
| Door swing | 20–25″ in front (front-load); ~20″ above (top-load) | A door you can never fully open |
| Delivery path | Narrowest doorway and every turn | A failed delivery |
| Hookups | Gas? 240V 3- or 4-prong? Water, drain, vent? | Buying a machine you can’t connect |
Then choose the configuration
Your numbers will usually decide this for you:
- 54″+ of width: side-by-side. The better setup, if you have the wall.
- 27–30″ wide and 75″+ tall: stack a front-load pair.
- Neither: a laundry center or an all-in-one combo.

Bring the numbers with you
Write them down, photograph the outlet and the vent, and bring it all when you shop. Used and scratch-and-dent inventory is one-of-a-kind, so "I’ll go home and measure" is how people lose the set they wanted. If you’re unsure about a tight fit, call us with your dimensions and we’ll tell you honestly whether it’ll work.
Frequently asked questions
How much space do I need behind a washer and dryer?
About 6 inches beyond the appliance’s spec depth, for hoses, the electrical connection, and the vent duct. This is the measurement people miss, and it’s why closet doors won’t close on new machines.
How much clearance does a washer need on the sides?
About an inch per side. A washer touching the wall transmits spin-cycle vibration straight into the structure, which the whole house will hear.
How much room does a front-load washer door need?
Roughly 20–25 inches of clearance in front of it to open fully. Check this before buying if your laundry space is a narrow closet or hallway.
How tall does a laundry closet need to be for a stacked pair?
About 75–80 inches, and check the dryer’s control panel height, some stand up at the back and add inches the main spec doesn’t include.
What measurements do I need before buying a washer and dryer?
Six: width (minus side clearance), depth (plus 6 inches), height (including any control panel), door swing, the delivery path, and your hookups (gas, 240V plug type, water, drain, vent).
