Choose your washer first, then match a dryer to its capacity and your home’s hookups — that order prevents mismatched pairs and failed installations.
Picking a new washer and dryer is a two-step decision, and the order matters more than most shoppers realize. Consumer Reports puts it plainly: “Whether you opt for a manufacturer’s set or create your own pair, we recommend choosing your washer first.” That advice exists because the washer does the heavy lifting on cycle options and load sizes, while the dryer mainly needs to keep up with it. Here is the process that works, from measuring your space to confirming hookups, without the guesswork.
Start With Space and Measurements
Before shopping, measure the laundry area with a tape measure — including baseboard trim, which eats more room than people expect.
Write down the width, depth, and height of the opening. Confirm the door swing direction works in your space before you commit.
Size the Washer for Your Household
Washer capacity is measured in cubic feet, and the right size depends on how many people live in the house.
Think about your biggest laundry items too. If bulky bedding is a regular load in your house, size up.
Match the Dryer to the Washer
That 1:2 ratio gives clothes enough room to tumble freely, which is what actually dries them. Pairing a large washer with a too-small dryer leaves comforters wet in the center after a full cycle, forcing a second run that wastes time and energy.
There’s no single standard size — you’ll find a set that fits your household if you check the specs.
Confirm Venting, Hookups, and Stacking Rules
Dryers come in two flavors: vented electric and gas. Look at what your laundry room already has before you pick. Cords and vent hoses need that 4 to 6 inches of clearance at the back, so factor it into your depth measurement.
The common mistake is assuming any two machines can be stacked. They can’t — the washer and dryer must be from compatible model families, and the kit must match both. When in doubt, buy a matching set or confirm compatibility with the manufacturer before you order.

One more checklist item: measure the doorways and hallways the machines must travel through. A washer that fits the laundry room may still not fit through a narrow basement stairwell. Measure those openings before delivery day, not after.
| Sizing Question | What Works | Why It Matters |
|---|---|---|
| 1–2 people | 2–3 cu. ft. washer | Covers everyday loads without wasting water |
| 3–4 people | 3–4.5 cu. ft. washer | Handles family-sized loads in fewer cycles |
| 5+ people | 4.5–6.2 cu. ft. washer | Processes large loads without overloading |
| Bulky items (comforters) | 4+ cu. ft. washer, large dryer | Prevents wet, tangled bedding after the cycle |
| Dryer for any washer | Roughly 2x washer capacity | Allows proper tumbling for efficient drying |
| Side clearance | 1–3 inches between units | Prevents vibration damage and allows access |
| Rear clearance | 4–6 inches for vents and cords | Keeps hoses from kinking and blocking airflow |
Once you’ve settled on sizes and confirmed your hookups, the final decision is between a matched set and a DIY pair. A manufacturer set guarantees compatibility and often simplifies installation; mixing brands works fine when you match capacity and width, but you’ll need to verify the stacking kit and pedestal compatibility yourself. Whichever route you take, the washer-first order keeps the whole project on solid ground.
