What Size Dumpster Do I Need? (10, 20, 30 & 40 Yard Guide)

Roll-off dumpsters are sized in cubic yards of volume. One cubic yard is about 202 gallons (CT DEEP). Here is how to match a size to your project, using published data from haulers and price trackers.

Quick answer

10 yard: small cleanouts and heavy debris (concrete, dirt, brick).
20 yard: the most-rented size — kitchen/bath remodels, roofing, flooring, mid-size cleanouts.
30 yard: larger remodels, big cleanouts, light demolition.
40 yard: major construction, whole-home cleanouts, commercial jobs.

In a 2026 industry benchmark of 1,671 hauling companies, the 20-yard was the most-rented size (31.9% of rentals), ahead of the 30-yard (27.8%) (Docket 2026 Benchmark Report).

Size comparison

Size	Typical dimensions¹	Republic Services dimensions²	Pickup loads²	32-gal bags²
10 yd	14′ × 7.5′ × 3.5′	12′8″ × 8′3″ × 4′4″	~4	~60
20 yd	22′ × 7.5′ × 4.5′	22′9″ × 8′3″ × 4′4″	~8	~120
30 yd	22′ × 7.5′ × 6′	23′1″ × 8′3″ × 6′1″	~12	~180
40 yd	22′ × 7.5′ × 8′	23′1″ × 8′3″ × 7′9″	~16	~240

¹ Connecticut DEEP, Common Trash and Recycling Container Capacities. ² Republic Services roll-off sizes. Other haulers quote ranges, e.g. 3–4 / 6–8 / 9–12 / 12–16 pickup loads (Great Waste). Most standard containers are under ~8.5 ft wide, so plan for a driveway spot roughly 22–24 ft long for 20–40 yard boxes.

Which projects fit each size

10-yard dumpster

Republic Services lists it for heavy materials (concrete, brick, dirt) and small remodels; Great Waste lists small bathroom remodels, garage cleanouts and minor landscaping. WM's quick guide also lists small deck demolitions and moderate roofing debris (WM Roll-Off Quick Guide).

20-yard dumpster

Typical fits: office cleanouts, roofing, small remodels (Republic); kitchen remodels, roofing, flooring removal, medium cleanouts (Great Waste).

30-yard dumpster

Typical fits: mid-sized remodels and cleanouts, tree trimming, light demolition (Republic); whole-home renovations and new construction (Great Waste).

40-yard dumpster

Typical fits: large remodels, large cleanouts, construction, bulk materials (Republic); major construction and commercial demolition (Great Waste).

Heavy debris: size down, not up

Republic Services notes its larger-size pickup-load estimates are not for heavy items — brick, concrete, dirt, gravel, rocks or tile (Republic “What Size Dumpster Do I Need?”). Heavy loads hit the weight limit long before the container is full, so haulers steer them to 10-yard containers. Overloaded dumpsters may incur extra fees.

How much each size costs

Size	National median published price³	Typical range³
10 yd	$345	$295–$399
20 yd	$419	$350–$490
30 yd	$520	$445–$600
40 yd	$600	$499–$700

³ Dumpster Price Index, medians of 3,536 published prices from 1,395 companies (accessed Oct 22, 2026).

Published prices are starting prices. Other sources show higher real-world averages: Docket's 2026 benchmark (operator data) reports roughly $420–$590 for a 10-yard up to $830–$1,330 for a 40-yard, depending on region and term, and ConsumerAffairs' survey of one-week rentals found $423 for a 10-yard up to $1,026 for a 40-yard (Minneapolis) (ConsumerAffairs).

What drives the final bill

Weight allowance: the median published allowance is 2 tons, with overage around $76/ton (Dumpster Price Index).
Rental period: median 7 days included; extra days run a median $16/day (Dumpster Price Index).
Location: landfill distance and local disposal fees move prices; ConsumerAffairs cites Minneapolis as pricier due to facility fees.

Sizing tips

Estimate your debris in pickup-truck loads, then use the table above.
If you're between sizes, the next size up usually costs less than a second haul — confirm with your hauler.
For concrete, dirt, brick or shingles, ask about weight limits before choosing a size.
Confirm dimensions — they vary by hauler, as the table shows.
