The average size of a trash can is a question that often arises when planning waste management solutions for homes, offices, or public spaces. The answer, however, isn't as straightforward as one might think, as it varies based on several factors. Let's delve into this topic to understand the average sizes of trash cans and their applications.
Understanding Trash Can Sizes
Trash cans come in a variety of sizes, typically measured in gallons. The most common sizes are 8, 13, 18, and 32 gallons. However, the "average" size can vary depending on the context. For residential use, a 13-gallon trash can is often considered the standard. In contrast, commercial settings might require larger capacities, making a 32-gallon trash can more common.
Residential Trash Cans
In residential settings, the average size of a trash can is around 13 gallons. This size is popular due to its balance between capacity and convenience. It's large enough to accommodate a week's worth of household waste but small enough to be easily moved and emptied. Here's a breakdown of common residential trash can sizes:

- 8-gallon: Compact and lightweight, ideal for small apartments or bathrooms.
- 13-gallon: The standard size for most households, offering a good balance of capacity and convenience.
- 18-gallon: Larger capacity, suitable for families or households that generate more waste.
Commercial Trash Cans
In commercial settings, larger trash cans are typically used due to the higher volume of waste generated. The average size of a commercial trash can is around 32 gallons. These cans are designed for heavy-duty use and often feature durable materials and wheels for easy maneuvering. Here are some common commercial trash can sizes:
- 20-gallon: Suitable for small offices or break rooms.
- 32-gallon: The standard size for most commercial settings, including offices, restaurants, and retail stores.
- 64-gallon and larger: Used in high-waste volume areas like kitchens, event venues, or industrial facilities.
Factors Affecting Trash Can Size
The average size of a trash can can vary based on several factors. Here are some key considerations:
- Waste volume: The amount of waste generated is the primary factor determining trash can size. Households with more members or businesses with higher foot traffic will require larger cans.
- Space availability: Larger trash cans require more space. Therefore, the size of the trash can may be limited by the available space in the home, office, or public area.
- Waste type: The type of waste also influences trash can size. For example, recyclables and organic waste can be compacted, allowing for smaller cans. Conversely, bulky waste like cardboard or construction debris requires larger cans.
Choosing the Right Trash Can Size
When choosing a trash can, it's essential to consider your specific needs. For households, a 13-gallon can is a good starting point, but larger families or those who generate more waste may need a 18-gallon can. In commercial settings, a 32-gallon can is typically sufficient, but high-waste volume areas may require larger cans.

It's also crucial to consider the type of waste you'll be disposing of. If you have a recycling or composting program, you may need additional cans. And if you have specific needs, such as a need for a can with a lid or one with wheels, be sure to factor that into your decision.
In conclusion, the average size of a trash can varies based on the context and specific needs. By understanding the different sizes available and the factors that influence trash can size, you can make an informed decision when choosing a trash can for your home or business.
