Will it fit your washer

The arithmetic

Appliance makers size a load by weight against drum capacity. Samsung puts the rule at one pound of laundry per cubic foot of capacity for a small load, two pounds for a medium load, and three pounds for a large one, with a worked example: in a four cubic foot machine, four pounds is a small load, eight is medium and twelve is large.^[1]

Note that the rule takes capacity in cubic feet rather than a size class. "Medium", "large" and "extra large" are not standardised between manufacturers, and GE declines to define them for that reason, giving a figure only for compact and stackable machines, at roughly four to eight pounds a load.^[2] Your machine's actual capacity is on its label or in its manual, and that is the number the table below wants.

Run the shipping weights of this range through that rule and the results split cleanly. Everything up to and including 5 by 7 is a comfortable load in an ordinary domestic machine. 6 by 9 needs a large machine and fills it. 8 by 10 is borderline at the light end of the weight range and impossible at the heavy end. 9 by 12 does not fit any domestic washer sold for home use.

The table below does this for every size in the range, using the weights published on the listings themselves. It is not a judgement about the rug. A 9 by 12 that has to go to a laundrette is still a washable rug; it is just not a rug you wash at home.

Two things the arithmetic understates

A rug is denser than laundry. The three pounds per cubic foot rule was written for clothes, which trap air and tumble. A rug packs into a solid roll and moves as one mass. If your machine is exactly at the calculated figure, treat it as full rather than as adequate.

Wet weight is not dry weight. Polyester absorbs relatively little water compared with cotton or wool, which is one of the genuine advantages of this construction, but a soaked rug is still heavier than a dry one and the spin cycle is where an overloaded machine complains. If the drum thumps or the machine walks, stop it and take the rug out; you are past the limit regardless of what the arithmetic said.

If your rug is too big for the machine

A commercial machine at a laundrette will normally take an 8 by 10 and often a 9 by 12; the large front loaders in those rows run well past domestic capacity. Failing that, the practical route for a large rug is the one used for any large rug: vacuum it regularly, blot spills immediately, and clean the whole thing on a hard floor or driveway with cool water and a mild detergent rather than in a drum.

Whatever the size, the wash instructions on these listings are consistent and worth following exactly: cold water, gentle cycle, no bleach, and either line drying or a no heat air cycle. Heat is what damages the rubber backing, not water.
