Estimating Your Daily Waste Volume

If you're unsure about your daily waste volume, consider these guidelines:

  • Small household (1-2 people): 1-2 gallons per day
  • Medium household (3-4 people): 2-3 gallons per day
  • Large household (5+ people): 3-4+ gallons per day
  • With pets: Add 0.5-1 gallon per day

Understanding Bag Types

Different bag types offer different capacities and durability:

  • Standard 30-gallon bags: Best for small households with minimal waste
  • Duty-duty 40-gallon bags: Recommended for medium households or when liners are used
  • Large 50-gallon bags: Ideal for large households, those with pets, or when maximum capacity is needed

Additional Tips

Consider these additional factors when choosing your trash bag size:

  • Wet waste increases bag weight significantly
  • Liners add extra bulk to each bag
  • Some municipalities have restrictions on bag size
  • Buying in bulk (e.g., 4-pack) can save money
