# 30 yard dumpster

Direct answer
A 30 yard roll-off holds 30 cubic yards, roughly 12 pickup truck loads. Expect 20–22 ft long, 7.5–8 ft wide and 5.5–6.5 ft tall, with 3 to 5 tons included. Those dimensions are ranges because a roll-off is sold by internal volume and every manufacturer builds a different box.

**Dimensions**: 20–22 ft × 7.5–8 ft × 5.5–6.5 ft

**Weight limit**: 3–5 tons

**Pickup truck loads**: ~12

**33 gal bags**: 125–185

**Footprint**: 150–176 ft²

**Typical cost**: $400–$950

## Why a 30 yard dumpster has no single exact size

Roll-offs are sold by internal volume, not by external dimensions. Two haulers can both deliver a legitimate 30 yard container with different lengths and wall heights, because their manufacturers built to volume. That is why the numbers above are ranges, and why measuring your driveway against one published figure is how deliveries fail.

At 6 feet, the 30 yard is the first size where you stop throwing debris over the wall and start carrying it through the swing door. That changes how long the job takes more than most people expect.

## What a 30 yard container is for
- Whole-house or estate cleanout
- A major addition or gut renovation
- New construction framing waste
- Commercial tenant fit-out

### What it is the wrong choice for
- Driveways with overhead wires or a tight approach — this is where clearance problems start

## How much weight this container is allowed to carry

Typically 3 to 5 tons included, and that is a term your hauler sets rather than a property of the box. Over it you pay per ton, commonly $40 to $150. The hard ceiling is the truck’s legal axle weight, which is why a container can be too heavy to move while still looking half full.

5 tons included 3 tons over At $75/ton that is $225 added to the invoice.

## Whether to size up or down

Below this is the 20 yard. Above it is the 40 yard. If you are between two sizes, take the larger one — a second delivery costs a full base rental plus another trip charge, always more than the gap between sizes. The exception is dense material: for concrete, dirt or tile, order smaller containers more often, because you cannot legally fill a large box with heavy debris.
- 20 yard dumpster — The 20 yard is the most-rented size in the country and it is still 4 feet tall, so you can throw over the side instead of walking the door. That combination is why it is the safe default.
- 40 yard dumpster — A 40 yard is a volume container, not a capacity upgrade. The truck’s legal weight has not changed, so the extra 10 yards over a 30 only helps you if what you are throwing away is bulky and light.

## Projects this size suits
- Roof tear-off — Shingles are dense, so weight runs out long before volume. Size to the tonnage, not the pile.
- Kitchen remodel — Cabinetry is bulky and light, so volume is the binding constraint — unless there is tile, in which case weight takes over.
- Estate cleanout — Decades of household contents are almost pure volume, and the job is emotionally hard enough without running out of container halfway through.
- Basement flood cleanup — Water is the whole story. Saturated drywall, carpet, padding and stored cardboard can weigh several times their dry weight.
- Whole-house gut renovation — Volume and weight both bind, at different stages. Plan two or three containers in sequence rather than one enormous one.
