It's the first question we get on almost every call, and it's the right one to ask: what size dumpster do I need? Guess too small and you're paying for a second haul or watching debris pile up in the driveway through a Gulf Coast heat wave. Guess too big and you've rented empty air. After years of dropping roll-offs across Gulfport, Long Beach, Biloxi and the rest of Harrison County, we've learned that the honest answer depends on two things most folks never think about: how heavy your debris is, and how many pickup-truck loads it really adds up to.
This guide walks you through the four sizes we run most often, what actually fits in each, and how to avoid the two mistakes that cost people money. When you're ready to talk it through with a real person, call us at (228) 678-7239 and we'll size it with you in five minutes.
Start With Weight, Not Just Volume
Here's the thing nobody tells you. A dumpster has two limits: how much stuff physically fits inside it (volume, measured in cubic yards) and how much weight the truck can legally haul (measured in tons). For light, bulky junk like old furniture, cardboard, or storm-downed brush, you'll fill up the space long before you hit the weight cap. But for heavy debris? You'll hit the weight limit with the container barely half full.
Heavy debris is anything dense: concrete, brick, dirt, asphalt shingles, tile, and wet material. And down here on the coast, "wet" matters more than you'd think. Our humidity soaks into drywall, carpet, and yard waste and adds real pounds. A load of soggy tear-out from a bathroom that sat closed up all summer weighs noticeably more than the same debris would in a dry climate.
Rule of thumb: if your project involves shingles, concrete, tile, or dirt, size down on volume and ask us about the weight allowance first. If it's household junk, furniture, or brush, size up on volume and don't worry as much about the scale.
This is exactly why a 30-yard dumpster isn't always the "safe" choice for heavy work. Load a big container to the brim with shingles and you can create an overweight ticket the truck can't legally move. That's a headache for everyone. A quick phone call saves you from it.
The Four Sizes, Side by Side
Roll-off dumpsters are named for their volume in cubic yards. To make that mean something, we've translated each into pickup-truck loads (figure a standard full-size pickup bed holds roughly two to three cubic yards, loaded level) and matched them to the projects we see every week on the coast.
| Size | Typical Dimensions (L x W x H) | Holds (pickup loads) | Weight Allowance | Best For |
|---|---|---|---|---|
| 10-yard | ~14 x 8 x 3.5 ft | 3-4 loads | Lower cap, ideal for heavy debris | Small bathroom remodel, concrete/dirt removal, small cleanout |
| 15-yard | ~16 x 8 x 4 ft | 5-6 loads | Moderate | Larger bath or kitchen remodel, deck tear-out, mid-size cleanout |
| 20-yard | ~22 x 8 x 4.5 ft | 7-8 loads | Moderate to high | Garage/estate cleanout, roofing tear-off, flooring, storm cleanup |
| 30-yard | ~22 x 8 x 6 ft | 9-12 loads | High volume, light debris | Whole-home renovation, new construction, major hurricane cleanup |
Dimensions vary a little by container, but the footprint is close. Notice that a 20 and a 30 have nearly the same length and width. The 30 just has taller walls. That matters for your driveway: all four sizes fit in a standard residential drive, so pick by capacity, not by whether it'll fit.
The 10-Yard: Small Footprint, Heavy Hitter
Don't let the small size fool you. The 10-yard dumpster is our workhorse for dense debris. A single bathroom remodel with old tile, a cast-iron tub, and wet drywall can max out the weight limit while the box still looks half empty. Same story for a concrete patio removal or a load of dirt from a landscaping dig. Its low walls make it easy to toss heavy pieces over the side instead of hauling them up high. If your project is small in footprint but heavy in material, this is almost always the right call.
The 15-Yard: The In-Between
The 15-yard fills the gap when a 10 feels tight but a 20 feels like overkill. Think a full kitchen gut, a good-sized deck tear-out, or clearing a couple of rooms of flooring and furniture. It's a comfortable middle for the homeowner who's doing a real project but not a whole-house overhaul.
The 20-Yard: The Most Popular Choice
If we had to bet on one size for the average Gulfport homeowner, it'd be the 20-yard. It swallows a full garage cleanout, an estate clear-out, or a big flooring-and-drywall job with room to spare, and the taller-but-not-too-tall walls are still manageable. It's also the size we point most people toward for a roofing tear-off on a typical single-family home, though here's where weight comes back into play. Asphalt shingles are dense, and a full roof of layers can push a 20 near its weight cap. On bigger or multi-layer roofs, we'll sometimes recommend a 10 or 15 sized specifically for the shingle weight rather than the volume. Tell us the square footage and how many layers are up there and we'll get it right.
The 30-Yard: Big Jobs and Storm Season
The 30-yard dumpster is for volume, not weight. Whole-home renovations, new construction framing scrap, and major cleanouts where you're generating a mountain of light, bulky material. It's also the container we run hardest after a storm. When a hurricane or a bad summer squall comes through the coast, the debris is enormous in volume, downed limbs, ruined furniture, waterlogged drywall, fencing, so having those tall six-foot walls means fewer hauls and faster recovery. Just remember: once storm debris is soaked and you start mixing in anything heavy, we'll talk through the weight so the truck can actually move it.
How to Size Your Specific Project
Walk the job before you call. Picture how many pickup loads you'd need to haul it yourself, then use the table above. When you're between two sizes, the tiebreaker is debris type: heavy material, go smaller on volume; light and bulky, go bigger. A few real examples from around Harrison County:
- Guest bathroom remodel: 10-yard. Small space, but heavy tile and fixtures.
- Two-car garage cleanout: 20-yard. Lots of bulky junk, mostly light.
- Reroofing a 2,000 sq ft home: 20-yard for a single layer, but call us on the shingle weight for multi-layer.
- Kitchen and living room renovation: 15 or 20-yard depending on cabinets and flooring.
- Whole-home gut or new build: 30-yard, possibly with a swap-out.
- Post-storm yard and interior cleanup: 30-yard for the volume of brush and soft debris.

Don't Forget the Weight Conversation (and the Cost)

We're locally owned, we know these neighborhoods, and we'd rather spend five minutes getting your size right than sell you the biggest box on the lot.

Frequently Asked Questions
What size dumpster do I need for a bathroom remodel?
For most bathroom remodels, a 10-yard dumpster is the right choice. Bathrooms are small in square footage but the debris, old tile, a cast-iron tub, wet drywall, is heavy and dense. You'll typically hit the weight limit before you run out of space, so a smaller container sized for that weight is smarter and more cost-effective than going big.
What size dumpster do I need for a roofing tear-off?
A 20-yard dumpster handles a typical single-family roof tear-off well. Keep in mind that asphalt shingles are heavy, so a large roof or multiple layers can push you toward the weight limit. Tell us the roof's square footage and number of layers when you call (228) 678-7239 and we'll match the size to the shingle weight, not just the volume.
Will a roll-off dumpster fit in my Gulfport driveway?
Yes. All four common sizes, 10, 15, 20 and 30-yard, are about 8 feet wide and fit in a standard residential driveway. The main differences are length and wall height, not footprint width. We'll place it to protect your surface and leave you room to work. Just clear the drop spot of vehicles and low branches before we arrive.
Why does debris weight matter more than size?
Every dumpster has both a volume limit and a weight limit, and the truck can only legally haul so many tons. Heavy debris like concrete, tile, shingles and dirt reaches the weight cap long before the box is full. On the Gulf Coast, humidity also adds weight to drywall, carpet and yard waste. Sizing by weight avoids overage charges and keeps the load legal to move.
What size dumpster is best for hurricane or storm cleanup?
For storm cleanup, a 30-yard dumpster is usually best because the debris, downed limbs, fencing, ruined furniture and waterlogged drywall, is huge in volume but relatively light. The tall walls mean fewer hauls and faster recovery. If your cleanup includes heavy material, call us at (228) 678-7239 so we can factor in the weight and keep everything moving.
