Dealing with an constantly overflowing outdoor trash bin is frustrating, but calculating the right capacity is easier than you think. Start by tracking your current waste output - for one week, note how quickly your bin fills up and what day it typically overflows. Most households find that a 32-35 gallon bin works well for 2-3 people, while larger families of 4-6 might need 64-96 gallons.
Consider these key factors: your household size, how often trash collection occurs, your recycling habits, and any special circumstances like frequent entertaining or diaper usage. Here's a simple calculation method: measure your current bin's dimensions (height, width, depth) and multiply them to get cubic volume, then convert to gallons (multiply cubic feet by 7.48).
If your bin overflows between collections, you likely need at least 30-50% more capacity. Don't forget that proper waste management can reduce your needs - recycling more materials and composting food scraps can significantly decrease your trash volume. Many homeowners find that having two smaller bins works better than one large container, especially if you separate regular trash from recyclables.
Look for bins with built-in compression features if space is limited, as these can effectively increase capacity without taking up more room. Remember that seasonal changes affect waste too - during holidays or summer barbecues, you might generate more trash temporarily. The goal is finding a bin that accommodates your peak usage without consistently overflowing, while still fitting your space constraints and local regulations.
