Compost Bin Size Calculator

Right bin size for your household waste. Weekly volume, tumbler vs pile recommendation.

Updated April 2026
Weekly waste (lbs)
6.0
Weekly volume
4 gal
Recommended size
~64 cu ft
First compost in
3-6 months

Recommendation: 4x4x4 ft pile/bin (~64 cu ft) or dual-chamber tumbler (~10 cu ft).

Tumbler vs pile: an open pile or large bin handles higher yard-waste volume better; a tumbler can still help finish batches in 4–8 weeks.

Kitchen scraps contribute 3.5 lb/wk; yard waste adds 2.5 lb/wk. Material compresses roughly 4:1 as it breaks down.
