What Size Dumpster Do I Need? A Commercial Roll-Off Size Guide
The short answer: for most commercial work a 20 yard roll-off handles ongoing construction debris and mid-size renovations, a 30 yard suits new construction and larger demolition, and a 40 yard fits heavy commercial and industrial volume. A 10 yard is best for small cleanouts and tight sites. The right size depends on how much debris you have, how heavy it is, and how much room the site has for placement.
Ordering the right size the first time saves you swap fees and downtime. Below is a size-by-size breakdown, then guidance for common commercial job types.
Roll-off dumpster sizes at a glance
| Size | Dimensions (L x W x H) | Weight allowance | Holds about | Best for |
|---|---|---|---|---|
| 10 yard | 12 x 8 x 3.5 ft | ~2 tons | 3 to 5 pickup loads | Small cleanouts, tight sites, heavy dense debris |
| 20 yard | 16 x 8 x 4 ft | ~3 tons | 6 to 8 pickup loads | Ongoing construction debris, mid-size renovations, roofing |
| 30 yard | 20 x 8 x 6 ft | ~5 tons | 9 to 12 pickup loads | New construction, larger demolition, big cleanouts |
| 40 yard | 22 x 8 x 8 ft | ~8 tons | 12 to 16 pickup loads | Heavy commercial and industrial volume, large demolition |
Weight allowances are typical included tonnage. Heavy material like concrete, brick, or dirt fills the weight limit long before the volume limit, so those jobs often need a smaller size or a dedicated heavy-debris container.
What size dumpster for a commercial roofing tear-off?
Most roofing tear-off jobs use a 20 or 30 yard roll-off, sized to the roof area and the number of shingle layers. Because roofing fills fast, the bigger question is often swap frequency rather than size, keeping a full container swapped so the crew is not waiting. A 30 yard reduces the number of swaps on a large or multi-layer roof, and our roofing teams plan swaps to the pace of the crew.
What size dumpster for a retail or restaurant remodel?
Retail and restaurant remodels usually run a 20 or 30 yard for fixture, drywall, and general demolition debris. If the remodel includes heavy flooring, tile, or concrete, drop to a 20 yard or add a separate heavy-debris container so you do not blow past the weight limit.
What size dumpster for concrete, brick, or dirt?
Heavy inert material is a weight problem, not a volume problem. A 10 or 20 yard is usually the right call for concrete, brick, asphalt, or dirt, because a larger container will hit its weight limit while still looking half empty, and overweight loads add cost. For clean concrete, ask about a dedicated concrete container.
How to avoid ordering the wrong size
- Estimate your debris in pickup-truck loads and match it to the table above.
- Weigh heavy material separately in your head: concrete, tile, and dirt need smaller containers.
- Leave room for placement and truck access, a 40 yard needs about 60 feet of clearance to drop and pick up.
- On a long job, a smaller container with scheduled swaps often beats one oversized container.

Frequently asked questions
What size dumpster do I need for a commercial project?
For most commercial work a 20 yard handles ongoing construction debris and mid-size renovations, a 30 yard suits new construction and larger demolition, and a 40 yard fits heavy commercial and industrial volume. A 10 yard is best for small cleanouts, tight sites, and heavy dense debris.
What are the dimensions of a 20, 30, and 40 yard dumpster?
A 20 yard is about 16 by 8 by 4 feet, a 30 yard about 20 by 8 by 6 feet, and a 40 yard about 22 by 8 by 8 feet. All are 8 feet wide, so plan placement and truck access accordingly.
What size dumpster do I need for a roof tear-off?
Most roofing tear-offs use a 20 or 30 yard, sized to the roof area and number of shingle layers. On large or multi-layer roofs a 30 yard reduces the number of swaps, and keeping the container swapped matters more than raw size.
What size dumpster for concrete or heavy debris?
A 10 or 20 yard, because heavy material like concrete, brick, and dirt hits the weight limit long before it fills the volume. A larger container will look half full and still be overweight, which adds cost.
How much weight can a roll-off dumpster hold?
Typical included allowances are about 2 tons for a 10 yard, 3 tons for a 20 yard, 5 tons for a 30 yard, and 8 tons for a 40 yard. Weight over the included allowance is billed as overage, so size heavy material carefully.
