What to Consider When Choosing a Container Size

The 3 biggest factors that you should consider when choosing a dumpster size are:

Amount and Type of Debris

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

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, instantly doubling your intended budget.

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

On average, sizing up costs less than $100 and can easily save you money in the long run.

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.

Most roll-off containers are 8 ft wide, but the length of the dumpster increases as you size up.

When considering the space you need, keep in mind that dumpsters typically have either one 8 ft wide door or two 4 ft wide doors that swing open on the back.

These doors make walking in heavy items much easier, so be sure to account for the additional 4-8 feet of space needed to utilize this feature.

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 can be intimidating if you're a first-time renter, but the professionals you rent from are incredibly good at helping you make the best decision for your disposal needs.

Renting a dumpster from a local company is almost always a better deal than renting from large, national waste companies.
