20 Yard dumpster rental in
St. Louis, Missouri.

A 20 yard dumpster holds 20 cubic yards of debris — roughly 6-8full-size pickup truck loads. Here's what that looks like for real projects in St. Louis:

• About 100-120 thirteen-gallon trash bags
• Roofing shingles from a 1,500 sq ft roof (single layer)
• Full kitchen demo including cabinets, countertops, flooring, and drywall
• Debris from renovating 2-3 rooms simultaneously
• A whole-house declutter for a small to mid-size home

The 20 yard dumpster is the most popular size for good reason — it handles the majority of home renovation and cleanout projects at a reasonable price point. It's the go-to choice for kitchen remodels, roof tear-offs (single layer on homes up to 1,500 sq ft), and multi-room cleanouts. At 4.5 feet tall, it's still low enough that most people can toss debris over the side without a ladder. If you're on the fence between a 15 and 20, go with the 20 — the cost difference is minimal, and running out of space means paying for a second haul.

Pro tip for St. Louis rentals: If you're unsure about sizing, call a few local haulers and describe your project. Most St. Louisdumpster companies will recommend the right size based on years of experience with local projects — and it's in their interest to get it right, since swapping out a dumpster mid-project costs everyone time and money.
