What Is the Largest Capacity LG Washer? | 5.8 Cu. Ft. Winner

If you’re tired of running three loads for what should be one, the answer to what is the largest capacity LG washer comes down to a single model: the LG SIGNATURE WM9500HKA. This front-loader tops LG’s U.S. catalog at 5.8 cubic feet, and LG’s own product page states it can wash a king-size comforter plus a full bedding set in a single cycle. For most households, that capacity gap is the difference between laundry day and laundry week.

Below is how the biggest LG models stack up, what the number actually means for your clothes, and where the top-load options fall.

How LG’s Largest Washer Models Compare

LG sells several large-capacity washers, but they are not all created equal. The WM9500HKA holds the top spot at 5.8 cu. ft., while other front-loaders and top-loaders sit just below it. The table below lays out the current U.S. options by drum size.

That figure represents two separate drums working together, not a single larger tub.

What 5.8 Cubic Feet Actually Means For Your Laundry

Capacity in U.S. washer specs is measured in cubic feet of drum volume, not weight. A 5.8 cu. ft. drum holds roughly two to three times what a standard 4.0 cu. ft. machine handles, which translates to fewer cycles and less water usage over a week’s worth of laundry.

LG’s own materials for the WM9500HKA highlight the real-world use case: a king-size comforter and a full set of bedding fit together in one load. That single capability eliminates the most frustrating chore in bulky-item washing. Oversized items beyond comforters—like thick duvets or multiple blankets—may still need individual loads, since LG’s claim covers bedding, not every bulky object you own.

The operational benefit scales with the drum. LG’s top-load category page notes that larger capacities reduce the number of cycles needed, which is the same math that applies to the front-load WM9500HKA. Fewer loads mean less time, less detergent, and lower energy use over the machine’s life.

Is There A Bigger Top-Load LG Washer?

LG’s U.S. top-load washers top out at 5.5 cu. ft. on the consumer product pages, which places them slightly below the WM9500HKA front-loader. A separate LG U.S. business page lists the WT7700HVA at 5.7 cu. ft., but that figure appears on a commercial-oriented listing and conflicts with the consumer top-load page, so it needs verification against the live product listing before you treat it as a final answer.

The picture gets murkier if you look outside the U.S. If you’re shopping in the states, the 5.8 cu. ft. WM9500HKA is the single largest drum you can buy from LG with official U.S. backing.

Smart features come standard on the flagship. The WM9500HKA includes Smart Wi-Fi connectivity through LG’s ThinQ app, which lets you start, monitor, and diagnose cycles from your phone. TurboWash technology also cuts cycle times by using high-pressure jets to penetrate fabric faster.

Is The LG SIGNATURE WM9500HKA Worth The Price?

Those figures come from retailer listings rather than official LG MSRP, and washer prices shift frequently with promotions. Verify the current price on LG’s live product page before committing, and watch for bundle deals that include the SideKick pedestal.

The value case rests on the capacity itself. If you regularly wash bulky bedding, sports gear, or large family loads, the 5.8 cu. ft. drum cuts your total weekly cycles noticeably. If your laundry volume is modest, a 4.5 cu. ft. model like the WM3400CW will do the job for hundreds less. LG’s own documentation confirms the king-size bedding capability only on the WM9500HKA, so that feature has no substitute lower in the lineup.

FAQs

Does an LG washer’s cubic feet rating include the drum or the whole machine?
The rating measures the interior drum volume where clothes go, not the physical footprint of the appliance. A 5.8 cu. ft. washer can still fit in a standard 27-inch-wide laundry space.

Can I wash a queen-size comforter in a 4.5 cu. ft. LG washer?
Usually yes, but with less room to spare. A queen comforter typically fits in a 4.5 cu. ft. drum; a king comforter needs the 5.8 cu. ft. WM9500HKA to wash comfortably alongside other bedding.

Does larger washer capacity use more water per load?
Not proportionally. A 5.8 cu. ft. washer uses more water than a smaller drum per cycle, but because you run significantly fewer loads, total water usage across the same amount of laundry typically drops.
