Based on yard waste, kitchen scraps, and composting method.
Compost Bin Recommendation
Compost bin sizing depends on your waste output and composting method.
Waste generation estimates:
| Source | Weekly Volume |
|---|---|
| Kitchen scraps (per person) | 2-4 gallons (8-15 L) |
| Small yard (under 2,000 sq ft / 186 sq m) | 3-5 gallons (11-19 L) |
| Medium yard (2,000-5,000 sq ft / 186-465 sq m) | 5-10 gallons (19-38 L) |
| Large yard (5,000+ sq ft / 465+ sq m) | 10-20 gallons (38-76 L) |
Recommended bin sizes:
| Household | Bin Volume |
|---|---|
| 1-2 people, small yard | 30-40 gal (115-150 L) |
| 2-4 people, medium yard | 50-80 gal (190-300 L) |
| 4+ people, large yard | 80-120 gal (300-450 L) |
Composting method affects size:
- Hot composting: Needs minimum 27 cubic feet (765 L) to generate heat
- Cold/passive: Any size works, just slower
- Tumbler: Usually 40-80 gallons (150-300 L)
- Worm bin: 1 sq ft (0.09 sq m) surface area per person
Ideal brown-to-green ratio: 3:1 by volume. Browns = dry leaves, cardboard. Greens = food scraps, grass.
