The Most Popular Dumpster Size in Connecticut

The 20-yard has led every year on record

No suspense here: the 20-yard is Connecticut's workhorse, leading the mix in all four years. It's the size that covers a whole-home cleanout, a large renovation, or a single-layer roof tear-off, which is most of what generates a dumpster in the first place. But its share has drifted — 43% in 2023 down to 36% in 2026 YTD — and where that share went is the more interesting story.

The 15-yard is the quiet winner

The 15-yard grew from 19% of rentals in 2023 to 24% in 2026 year-to-date — the only size with share growth in every single year of the table. Our read from the driver's seat: renters are getting smarter about matching the can to the job. The kitchen reno, the garage clearout, the estate downsizing that doesn't empty the whole house — these were historically booked as 20-yards "to be safe" or crammed into 10-yards to save money. The middle tier is where a lot of real projects actually live, and the market is finding it.

The real decision is 10 vs. 20 — and at Grizzly, it's the same can

Add it up: the 10-yard (34%) and the 20-yard (36%) together are 70% of our 2026 rentals so far. For most renters, "what size dumpster do I need" collapses to that one call.

Here's the part that surprises people: at Grizzly, that decision carries zero risk of getting the box wrong — every size arrives as the same physical can. What you're choosing between sizes is the weight allowance (1,000 lbs at $447 on the 10-yard tier vs. 4,000 lbs at $647 on the 20), not the loading space. Book the 10-yard tier for a light, bulky load and you still get the full can to load into; if the project grows, upgrading is a phone call, not a swap-out truck roll. The One Can page explains the whole model.

That makes the honest sizing question about weight, not volume: dense debris — plaster, tile, roofing, anything rained on — is what moves a job from the 10-yard tier to the 20, and the overage fee guide shows exactly what the math looks like when a load runs past its allowance.

The 30/40 tier is small for a reason

At 7% of 2026 rentals, the 30/40-yard tier is the specialist: full additions, multi-building cleanouts, contractor volume. We deliver it as two 20-yard cans — same total capacity, one can's footprint at a time if you take the swap approach — which suits the driveways it actually gets ordered for.

Where to go from here

Sizing a specific project? Each size page walks project types against weight allowances, and town-level pages like 20-yard dumpster rental in Stamford cover local logistics. Timing a rental? Demand nearly doubles from winter to summer — the seasonality guide has the month-by-month curve. And for what these rentals cost across the state's market, see the Connecticut Dumpster Price Index and our own Fairfield County Dumpster Cost Report.
