I've used a older Miele and current Bosch 24"w 6kg washers (current top of the line model, don't feel like looking up the model number) and found both to be adequately large - they have about the same capacity as the old top-load washers I used to routinely use. I don't get the American obsession with huge appliances - nearly everywhere else in the world a 24" wide washer (or oven, or cooktop, or fridge) is considered standard size, not some compact appliance suitable only for one-bedroom apartments. But here in the US, even 27" is evidently too small for some, as LG and Samsung are now pushing 29" wide, 29" deep washers and dryers. Any larger and the things wouldn't fit through the doorway into the laundry room.

I do find the door opening of the Miele to be a bit small - not sure if the new ones are bigger or not. The Bosch has a larger door opening and is fine. The door openings and capacity of 27"w washers is noticeably larger still - especially on those that tilt the tub slightly - but not really necessary for fitting even large items like sheets and comforters into it. Given the choice, I found 240v power (and resulting fast water heating and ability to run off cold water only) and ability to fit under a standard countertop to be more important than huge capacity.

I have a sibling who has a recent, oversize washer and dryer that I've used occasionally, and whenever I fill it to capacity, I'm struck by how heavy and unwieldy the bag or basket of dried laundry that I pull out of the dryer is. It's too big and heavy to comfortably lift up the stairs at one time.
