That's a great and practical question! For a family of four, the most commonly recommended size for an outdoor trash can is between 32 and 44 gallons. A 32-gallon can is often a perfect starting point for many households, while a 44-gallon can provides a comfortable buffer, especially if you generate more waste or have less frequent pickups.
However, the "perfect" size isn't just about the number of people. Here are key factors to consider:
* Pickup Schedule: If your trash is collected weekly, a 32-44 gallon can is typically sufficient. For bi-weekly pickup, leaning toward the larger 44-gallon size (or even having two cans) might be necessary.
* Your Household's Habits: Do you cook at home a lot, using more packaging? Do you have babies (diapers!) or pets? These increase waste volume. Conversely, a family dedicated to composting and rigorous recycling might manage well with a smaller can.
* Can Type: Standard rollout carts (provided by many municipalities) are usually 64, 96, or even 35 gallons. If you're buying your own, classic rubber or plastic cans come in the 20-44 gallon range. Always check your local waste company's size rules and weight limits.
* Recycling: Having a separate, dedicated recycling bin dramatically reduces what goes into your main trash can. This is often the secret to making a mid-size can work perfectly.
Quick Comparison:
* 20-30 gallons: Might be tight for a week, ideal for minimal waste producers or as a recycling/bin.
* 32-44 gallons (Recommended): The sweet spot for most four-person families.
* 64+ gallons: Often provided by cities; can be large for four people unless waste generation is high.
Final Tip: When in doubt, measure your current bagged trash for a week. If you fill about two 13-gallon kitchen bags, a 32-gallon outdoor can is ideal. If you're closer to three full bags, size up to 44 gallons. It's about finding a can that contains your weekly waste without being so large it becomes heavy or difficult to move.
