Almost always through the door, since a standard washer is 27 inches (69 cm) wide in the US and about 23.5 inches (60 cm) in Europe, both under a 30 inch door opening. The real squeeze is the laundry alcove or closet: you need the machine width plus about an inch of clearance each side, and 4 to 6 inches behind it for the hoses and connections. Stairs to a basement and a 90 degree turn strand more washers than doorways do.
A washing machine almost always clears the door, so the panic is usually misplaced, but it gets stranded in two specific spots: the narrow utility or closet opening, and the depth of the alcove once you account for the hoses behind it. The headline numbers: a standard US washer is 27 inches (69 cm) wide, a European one about 23.5 inches (60 cm), and both slide through a 30 inch door opening. What catches people is the space, not the doorway, because a front loader can be deep and the connections behind it eat several inches you did not measure.
In the US a standard washer is 27 inches (69 cm) wide, 38 to 39 inches (97 to 99 cm) tall, and 27 to 34 inches (69 to 86 cm) deep, with front loaders at the deeper end. In the UK and Europe a freestanding machine is narrower, about 23.5 inches (60 cm) wide and 21 to 25 inches (53 to 64 cm) deep, which is why they tuck under a worktop. Width is the dimension you carry through the door, and at 27 inches or less it clears a 30 inch opening with room to spare.
Two different numbers for two different stages. Through the door, it is the width, and that is rarely the problem. In the space, it is the depth plus the connections, because the inlet hoses, drain hose and plug add 4 to 6 inches (10 to 15 cm) behind the machine that the spec sheet does not include. So a 27 inch deep washer needs an alcove more like 32 to 33 inches deep before the door of the cupboard will close.
Measure the gap it lives in, not just the machine:
Yes, and it is the most common miss. The hot and cold inlet hoses, the drain hose looped into the standpipe, and the power lead all sit behind the machine and stop it pushing flush to the wall. Budget 4 to 6 inches, more if the hoses are stiff. Front loaders also need clearance in front for the door to swing open, usually the full radius of the door, so a tight cupboard that fits the box can still trap the door shut.
Stairs strand washers more than doorways, because the machine is heavy, rigid and cannot be tilted thin like a mattress. Measure the stair width between the walls or rail, the headroom on any half-landing turn, and the turn itself, since a 90 degree landing is where a washer jams. For a stacked washer-dryer, add the two heights plus the stacking kit and check the total against the door height and the ceiling, because a stack can run past 75 inches.
Measure the alcove and the route first, then shop to those numbers rather than the other way round. Compare your narrowest opening and your alcove depth to the listing, or run them through our furniture fit calculator, which checks a doorway, stair or lift in seconds. The same access trap catches a fridge, covered in will my fridge fit through the door.

A standard washer is 27 inches wide in the US and 23.5 in Europe, so it clears a 30 inch door easily. The real check is the space: leave about an inch of clearance each side, 4 to 6 inches behind for hoses, and room in front for a front loader’s door to swing. Measure the alcove and the route, including stairs and any 90 degree turn, before you buy, and lower the feet or pick a slimline model if it is tight.
