Choosing the right dumpster size is the most important decision in your rental. Too small and you'll need a swap-out or second container; too large and you'll pay for space you don't use. This guide walks through the dumpster and disposal bin sizes commonly available in St. Catharines, Ontario, what each holds and which projects each fits best.
How dumpster sizes are measured
Dumpster sizes are measured in cubic yards — the volume the container holds. A 10-yard dumpster holds roughly 10 cubic yards of debris, or about three pickup-truck loads. Dimensions vary slightly by provider, so always confirm exact measurements with your assigned provider. In Ontario, roll-off dumpsters are also commonly called disposal bins or bin rentals.
Small dumpsters (10–15 yards)
Small containers are ideal for modest cleanouts and heavy materials. Because of their lower sides, they're often the right pick for dense debris like concrete or dirt where a larger container would exceed weight limits.
- 10-yard — small cleanouts, garage decluttering, concrete and dirt.
- 12-yard — compact jobs with a little more room.
- 15-yard — partial remodels, small roofing jobs, multi-room cleanouts.
Mid-size dumpsters (20–25 yards)
Mid-size containers are the most popular choice for homeowners and contractors. They balance capacity and footprint, fitting in most driveways while handling full-home cleanouts and substantial renovations.
- 20-yard — full home cleanouts, kitchen and bath remodels, roofing.
- 25-yard — whole-home renovations, large roofing, major estate cleanouts.
Large dumpsters (30–40 yards)
Large containers are built for big debris volume. They're tall and best suited to job sites and commercial lots where clearance and access allow.
- 30-yard — large remodels, construction site debris, commercial cleanouts.
- 40-yard — major construction, demolition, large-scale commercial projects.
How to choose the right size in St. Catharines
Start with your project type and the volume of debris you expect. If you're unsure, select 'I'm not sure' when you request service and a local provider can help you choose. It's usually better to size up slightly than to risk running out of room mid-project.
