Direct answer
How many trash bags fit in a dumpster? One cubic yard is 201.97 US gallons, so a 33 gallon bag is about 6.1 to the yard if you could pack them perfectly. Real loose-packed bags leave void space, so plan on 4 to 6.

## The formula

One cubic yard is 201.97 US gallons, so a 33 gallon bag is about 6.1 to the yard if you could pack them perfectly. Real loose-packed bags leave void space, so plan on 4 to 6.

## Worked example

60 bags of 33 gallon household waste is roughly 10 to 15 cubic yards once void space is counted — a 15 yard container, not the 10 the theoretical number suggests.

## Assumptions
- Bags are assumed loose-packed, not compacted. You cannot compact a rental container and the hauler cannot either
- The range accounts for void space between bags, which is real and is why the theoretical figure misleads
