Picking the Right Dumpster Size for a Kansas City Home Cleanout

A 2,200 square foot home in Brookside that hasn't had a serious clean-out in fifteen years generates about six pickup-truck loads of stuff destined for the landfill. That's a 20 yard. If we said the same thing about a 4,000 square foot home in Mission Hills with a finished basement and a packed garage, we'd say 30. The math is consistent. Here's how we work it.

Start with square footage, then adjust.

The fastest sizing heuristic for a KC home cleanout: 1,000 square feet of living space generates roughly 3 cubic yards of cleanout debris on a typical job. So a 2,000 sq ft home → ~6 yards → 20 yard dumpster. A 3,000 sq ft home → ~9 yards → 30 yard. A small one-bedroom apartment cleanout → 2–3 yards → 10 yard.

This rule assumes "typical" contents — furniture, boxes, clothing, general clutter. It breaks down in three directions. Adjust up if the home has a packed garage, a basement that's been used as storage, or major furniture (waterbeds, exercise equipment, big-screen TVs). Adjust down if the home was actively occupied and tidy.

Why people pick wrong.

Almost all sizing errors go in the same direction: people pick too small. The mental anchor is the dumpster price ("the 10 yard is $300, the 20 is $385 — let's try the 10"). The actual cost of picking too small isn't the difference — it's the swap-out: pay flat-rate twice, lose a day to waiting for the empty unit, and possibly have to triage what stays and what goes mid-job.

The flip side rarely happens. Picking too big costs you exactly zero. An empty third of the dumpster on pickup day is the same price as a full dumpster. That's why we say: when in doubt, size up.

The garage problem.

The number one source of sizing surprises is the garage. People plan a "home cleanout" mentally including the house but forget about the garage, where decades of stuff accumulate quietly. Two old bikes, a broken treadmill, four storage tubs of holiday decorations, a never-opened second microwave, three rakes, a leaking gas can, and the box-spring that didn't get hauled away last move.

That garage adds 3–5 cubic yards alone. If the cleanout includes the garage — and it usually does — bump up one size. Garage cleanouts are our second-most-common job category for a reason.

What the 20 yard handles.

The 20 yard is the size we drop more than any other in Kansas City. It handles a whole-home cleanout of a 2,000–2,500 sq ft house with normal contents, a mid-size remodel (kitchen + one bath), a flooring tear-out from a 3,000 sq ft house, or a full garage purge with overflow into the basement.

It's 22 feet long, 8 feet wide, 4.5 feet tall — about the footprint of a parking space, clears most KC two-car driveways with room to walk around. The side-door swings open so you can walk in larger items rather than lift them over the rim.

When to step up to the 30.

Three signals: the cleanout includes the full house plus the basement plus the garage; the home is over 3,000 sq ft with normal density; or the property has had multiple decades of accumulation without intervening cleanouts (a classic estate cleanout case — see our guide to estate cleanouts in KC).

The 30 yard shares the 22-foot length and 8-foot width of the 20 — same footprint — but goes 6 feet tall. So it fits the same driveways but holds about 50% more by volume.

When to size down to the 10.

One-room cleanouts. Small apartment move-outs. Or any job where the volume is small but the material is heavy — concrete pieces from a basement repair, dirt from a garden teardown, roofing shingles. Heavy material hits weight caps fast; a 10 yard is rated for it. Larger sizes filled with concrete are physically illegal to haul.

The two-minute phone test.

The full sizing guide is on our what size do I need page. But honestly: tell us the home's square footage, whether the garage is included, and whether anything weird is involved (a hot tub, a piano, a hoarding situation). We size in about two minutes on the phone. Call (816) 427-6571.
