When you're staring at a mountain of laundry, it's tempting to squeeze in just one more T-shirt, one more towel, one more pair of jeans. But how you fill your washer can make the difference between clothes that come out truly clean and ones that may come out with detergent residue or trapped dirt.
Figuring out load size doesn't need to be complicated, though. You don’t need to measure or weigh anything, just use the drum as your guide:
- Small load: about ¼ full
- Medium load: about ½ full
- Large load: about ¾ full
- Extra-large load: full, but not packed
For both front-loaders and top-loaders, avoid pressing clothes down to make them fit better (this is a particularly common habit with top-loaders). You should still be able to slide your hand comfortably across the top to let the clothes tumble freely. If you have to pack the drum to squeeze everything in, it’s already too full.
Fabric and item type also matter more than people think. Everyday clothing like t-shirts and jeans can usually follow the standard fill levels, but bulky items such as comforters, duvet inserts, blankets, and mattress pads need extra space. These items expand significantly once wet. Heavy, absorbent materials like towels and fleece also become much heavier during the cycle. For any of these items, it’s often better to stay closer to half to two-thirds full.
Why load size makes a difference
Laundry isn’t just about soaking clothes in water; it’s about movement. As the drum turns, items lift and fall, helping detergent and water reach every surface. When there’s too much in the machine, that movement is restricted, which can trap dirt and detergent. Over time, overloading can also strain your washer, leading to faster wear and tear.
On the flip side, consistently running small loads may get the job done, but it’s not very efficient. You’ll end up using more water and energy than necessary over time, which adds up—especially in a busy household.
If you like numbers, here’s a general guideline: "Most machines can handle about 3 pounds of laundry per cubic foot of drum capacity," says Noah Pinsonnault, a reviews analyst in the Good Housekeeping Home Care & Cleaning Lab. But because fabrics vary so much in weight and bulk, it’s often easier (and more accurate) to rely on how full the drum looks rather than what the scale says.
And if you’re unsure whether you’ve overloaded the machine, there are usually clear signs. Clothes may come out with dry spots where water never fully reached the fabric, or still feel dirty or coated with residue. You might also notice excess wrinkling or clumping, or even an “off-balance” warning during the cycle—another common sign that the drum didn’t have enough space for proper movement.
