# The Dumpster Size Guide

When you look into roll off dumpsters, you will see that they are measured in cubic yards. The cubic yards indicate how much debris each one can hold.

When you understand the different sizes of a dumpster, it can go a long way in helping you select the best container for you. We have a chart below of common dumpster sizes to help you.

• 30 yard dumpster 22 ft. long by 8 ft. wide by 6 ft. high 30 cubic yards
• 40 yard dumpster 22 ft. long by 8 ft. wide by 8 ft. high 40 cubic yards

Please be aware that the sizes above are the most common you see, but there are companies that may be different.

#### What are Cubic Yards?

Cubic yards are a measurement of volume. A yard is typically 3 feet. So, if you think about a square that is 3 feet wide, 3 feet long, and 3 feet high, you have yourself a cubic yard.

If you look at a dumpster’s dimensions in feet, you can calculate the cubic yards that the dumpster can hold with this formula.

length ft X width ft X height ft = total cubic feet.

Then take your total cubic feet and divide it by 27 to get the number into cubic yards.

Total cubic feet / 27 = Cubic Yards.

When you look at the dumpster dimensions, they are typically given in feet and are measured around the outside. If you take the formula above, and use it for the outside dimensions, the volume will be slightly larger. To ensure accuracy, its best to use the interior measurements, if the measurements are not available, you can minus about 6 to 8 inches off each side.

#### Things to consider when selecting a container size

When you try to estimate how much debris you may have, it can be challenging, especially when you have large items that can take up a lot of space. It is important to make sure you get the right size to ensure you have a good dumpster rental experience.

#### A small dumpster can be an expensive mistake.

If you are trying to save money by trying to fit 15 cubic yards of debris in a 10 cubic yard dumpster. It will not fit and will most likely cost you more money. What will typically happen is you would have to request to switch out the dumpster. The dumpster company will come by and they will deliver another 10 cubic yard dumpster that is empty and haul your full one away. This will end up doubling your bill costing more money than just ordering a single 20 cubic yard dumpster. You can learn more about dumpster rental costs with our guide to dumpster rentals.

Another costly mistake is overfilling the dumpster. You must keep your debris at level or within the top of the dumpster. If your debris fill up higher than the dumpster you may have to pay more money.

When you fill a dumpster, it may seem like there is no problem in filling it above the rim. This is another costly mistake. The dumpster service cannot and will not hall your debris. It is considered a safety hazard for the driver, as well as other people on the road. The driver may let you know that the dumpster is too full, and cannot be taken until it is level, and you will be charged a trip fee. Sometimes, if the debris are light, he may level out the dumpster himself and leave the debris on the side for you to take care of. In cases like that, you may be charged a overfill fee.

Sometimes dumpsters may need to be delivered to a small driveway or alleyway, it is important to double check the size of the dumpster and compare it to the area you are having it dropped off. Dumpsters are typically about 8 feet wide, but the length of the dumpster will change depending how many cubic feet you may need.

When you consider the space you will need, it is also important to keep in mind that dumpsters typically have an 8 ft. wide door that swings open on the back. If you plan on loading through the door instead of loading through the top, then you want to make sure you add an additional 8 feet of length so that the door can swing open.

When you choose a dumpster, there isn’t really a best practice, but 10 yard dumpsters will suit most small residential clean outs.
