When you’re looking to rent a dumpster for a project, you might not know which size to get. Dumpster sizes are designated by cubic yards (10, 12, 15, 20, 30, or 40), but what do those numbers translate to? How much stuff can fit in each size, and which do you need?

Considering the dimensions you need for your project comes down to three factors: cost, property dimensions, and what you need to throw away.


The larger the dumpster, the more expensive it’ll be. That’s why most people try to go with the smallest option that will fit everything they need to throw out. While it’s important to be cost-effective, if you choose a dumpster that’s too small, you’ll have to get another one, which could be more costly than getting a large dumpster in the first place.

Also, consider the number of trips you’ll have to take to the dump to empty the rented dumpster. You don’t want to spend valuable time on multiple trips when you could get a larger dumpster and empty it in one trip.

Property Dimensions

The bigger the property, the more material you need to remove. If you have a large property, it can be easy to underestimate the amount of material you’ll need to remove. When there’s more space, the material may look small in comparison to the property size, but actually end up amounting to more than expected.

If the property you’re working on is large, it may be safer to use larger dumpster sizes than you think you’ll need. This accounts for the inevitable perspective of the elements compared to the property. If the property is smaller, the opposite is true, and you can go with a smaller-sized dumpster.

You’ll also need to consider if the property has space to store the dumpster there for the time allotted for the project. It can’t block access to the road or building. You may need to choose a dumpster based on what the property will allow rather than what would be best to accommodate the project.

Items You’re Disposing Of

What materials are you disposing of in your dumpster? This is an important factor to consider when determining which size dumpster you’ll need. If you’re throwing out large items that take up more space and you can’t break them down, you’ll need a bigger dumpster to make sure it can fit everything.

Also, if you’re going to put different kinds of elements in different dumpsters, plan accordingly. If the elements are harmful and can’t go into a dumpster like asbestos, cleaning fuel, undrained appliances, or fuel, you’ll have to use other professional services to get rid of them.
