If you’ve ever rented a dumpster before, you may have wondered why the common sizes include 20-yard, 30-yard, and 40-yard dumpsters when the size doesn’t seem nearly that big. This often leads to the question – why is it called a 20-yard dumpster when it doesn’t hold 20 yards of trash?
Determining Dumpster Sizes
Dumpster sizes are measured by the amount of volume they can hold. The most common sizes – 20-yard, 30-yard, and 40-yard dumpsters – correspond to how much space is available inside the dumpster walls and below the rim when measured in cubic yards, not the actual length or area of the dumpster.
For example, a 20-yard dumpster has room for 20 cubic yards of material. But this doesn’t directly convert to 20 yards in length, width, or height. Instead, it means there are 20 cubic yards of total volume space.
Why Use Cubic Yards for Measurement?
Cubic yards are used as the standard unit of measurement because they allow an easy way to quantify how much material can fit inside the dumpster. When renting a dumpster, you often have a general idea of how much trash and debris you’ll require to haul away. Measuring based on cubic yardage capacity provides a universal standard for choosing the right size dumpster for your needs.
For example, according to All Site Rentals, a 20-yard dumpster typically holds about 4-5 truckloads of material. So, if you had the equivalent of 5 truck loads of waste to remove, you’d want to choose at least a 20-yard capacity dumpster. The cubic yard measurement allows you to match your expected yardage disposal to the right dumpster for your rental.
Typical Dimensions by Dumpster Size
Since cubic yard measurement doesn’t translate directly into length by width measurements, [All Site Rentals’ dumpster sizes](https://www.allsiterentals.com/roll-off-dumpster-size-dimensions/) give these specifications for common dumpster dimensions:
20 Yard Dumpster
– Length – 14 ft
– Width – 8 ft
– Height – 3.5 ft
30 Yard Dumpster
– Length – 18 ft
– Width – 8 ft
– Height – 4 ft
40 Yard Dumpster
– Length – 22 ft
– Width – 8 ft
– Height – 6 ft
As you can see, the dumpsters get progressively longer from 20 to 40-yard models to accommodate a greater cubic yardage capacity in each size. But their widths remain standard at 8 feet across to fit the requirements for hauling without a special permit. When optimizing for volume, additional dumpster length allows more material to fit rather than gaining width. Their lengths allow two times (20 yards) to three times (30 yards) to four times (40 yards) as much volume capacity within the numeric cubic yard specifications.
Why 20 Yards is a Convenient Standard Size
So why choose 20 cubic yards as the benchmark for the smallest standard dumpster size? It comes down to convenience and matching what most residential and small contractor rental needs would require.
According to experts at All Site Rentals, the 20-yard dumpster is the most commonly rented “small” dumpster container. It provides enough room to dispose of waste from small remodelling projects, garage cleanouts, storage unit cleanouts, and other residential cleanup needs where several pickup truck loads of debris require hauling.
The 20-yard size also hits a sweet spot for easy transport without special permits. It keeps below limits for being hauled without wide load restrictions while providing substantial hauling capacity. Twenty cubic yards or 20-yard dumpsters have become an industry standard that balances convenient transportation; disposal needs for small waste projects, ease of use for DIY homeowners, and affordable rental pricing.
