What to Consider When Choosing a Container Size

Amount and Type of Debris

Estimating the volume of your debris is challenging, especially for household junk or construction debris.

Whatever your project, renting the right size dumpster is the first step to having a good dumpster rental experience.

understand dumpster sizing

Choosing a dumpster that's too small can be an expensive mistake.

If you attempt to save a few bucks by trying to squeeze your debris into a dumpster that's too small, you'll end up paying substantially.

The best-case scenario is you're left with the excess debris and have to figure out how to get rid of it later.

The worst-case scenario is you have to pay for two dumpsters to remove all the debris.

Avoid all of this by sizing up in a dumpster if you're even remotely unsure if your debris will fit.

On average, sizing up costs less than $100, which saves you money in the longrun.

Spacing at the Work Site

If you need the dumpster delivered to a small driveway or alley, be sure to double check the dimensions of the dumpster with the hauler and compare it to the space you have available.

It's typical for roll-off container sizes to be 8 feet wide, so width is usually not a difference maker, but the length of the dumpster does increase.

When considering the space you need, keep in mind that dumpsters typically have an 8 ft. wide door that swings open on the back (or two 4-foot doors).

If you plan on loading through the door (rather than throwing debris over the top), then add an additional 4-8 feet of length needed for the door to swing open.

Weight and Height Restrictions

A dumpster service cannot legally haul your debris on the road if the container is filled too high, for safety's sake.

If your dumpster is filled too high, you'll have to remove the excess yourself or be charged a fee if the dumpster company does it for you.

If your dumpster exceeds the weight allowance, you'll have to pay for the overage fees after it's weighed at the landfill or recycling facility.

Rent from a Local Dumpster Provider

Choosing a roll off dumpster size is not an exact science.

The good news is that if you're not sure, the companies you speak with will be able to recommend a size for you.

It's difficult to suggest a size without seeing your debris, but most haulers will do their best to help you pick the right container size.

We also recommend getting quotes from at least two or three providers to ensure you get the best service and price possible.
