Updated December 15, 2022

Dumpsters are incredibly convenient to use, whether you're renting a temporary roll-off dumpster or paying for ongoing commercial dumpster services, but determining which size dumpster is right for your needs is an important first step.

Roll-off dumpster sizes are measured in cubic yards and are usually offered as 10, 20, 30, or 40 yard dumpsters.

Some dumpster rental companies offer half sizes, like 15 yard dumpsters or 25 yard dumpsters, and even mini dumpsters in some cases, commonly ranging from 2-8 yards.

Getting a dumpster that is too small can lead to potential overage charges or delays in your cleanup project, whereas getting a dumpster that's too big means you're paying for more dumpster than you need.

Luckily, dumpster rental companies are pros at helping people determine which size is right for their particular project.

In this guide, we'll go over the most common dumpster sizes, what types of projects they can accommodate, and when that dumpster size is the right choice for you.
