That's a great question, and it's super specific to where you live! Since municipal rules vary so much, there isn't one universal "most common" size, but I can give you a clear breakdown of the typical standards and how to find yours.
Generally, in many U.S. cities, the most frequently provided or required size for automated collection trucks is the 64-gallon (242-liter) wheeled cart. It's a middle-ground option that works well for most single-family homes. You'll also commonly see 35-gallon bins for areas without automated trucks or for homes with less waste, and 96-gallon carts for larger families.
The key factor is your city's specific program. They often dictate the size, color, and even the brand of bin you must use. This ensures compatibility with their collection trucks' mechanical arms. Using a non-compliant bin might mean your trash gets left behind.
How to Find Your City's Standard Size:
1. Check Your Municipality's Website: Go to your city's "Sanitation," "Public Works," or "Waste Collection" department page. The rules and standard issue sizes are almost always listed there.
2. Look at Your Bill: Your waste collection fee might be tied to the bin size (e.g., a smaller bin may cost less).
3. Call 311: If you're in an area with 311 services, they can directly connect you to the right department for a definitive answer.
4. Observe Your Neighborhood: On collection day, take a quick look at the bins lined up. If most are identical, that's likely the city-provided standard.
In summary, while the 64-gallon cart is a widespread standard, the only way to be certain is to consult your local municipal guidelines. Choosing the right size ensures your trash is collected smoothly and helps you comply with local ordinances.
