That's a great and practical question! For a family of four, a typical and highly recommended starting point is a 30 to 40-gallon outdoor trash can. This size is generally considered the sweet spot for most households of that size.
Here’s a bit more detail to help you decide:
* Weekly Waste Estimate: On average, a family of four generates about 20-25 gallons of general waste per week. A 30-40 gallon bin provides a comfortable buffer for weekly pickup schedules without becoming overly heavy or difficult to move.
* Key Factors to Consider:
* Pickup Schedule: If your garbage is collected weekly, a 30-40 gallon can is perfect. If you have bi-weekly pickup, you might want to consider a larger can (45-50 gallons) or be prepared to use an additional bin.
* Recycling & Composting Habits: Families that actively recycle paper, plastic, glass, and metals, and compost food scraps will generate significantly less general waste. In this case, a 30-gallon can might be more than enough.
* Lifestyle & Consumption: Households with young children in diapers or those that use more packaged goods may find themselves at the higher end of the waste spectrum. Conversely, a minimalist household might need less capacity.
* Physical Practicality: Remember, a fully loaded 40-gallon can can be quite heavy. Ensure the person who will be moving it to the curb can handle the weight.
Final Recommendation: I'd suggest starting with a 35-gallon outdoor trash can. It's a versatile size that works well for most families of four with weekly service. You can always adjust later if you find you consistently need more or less space. The goal is to have a can that contains your weekly waste neatly without being constantly overfilled or mostly empty.
