Common questions about mulch weight.
How to Calculate
To calculate mulch weight, multiply the volume (in cubic feet) by the density of your mulch type. The formula is **Weight = Volume × Density**. Wood chip mulch has a density of ~20 lb/ft³, bark mulch ~25 lb/ft³, rubber mulch ~65 lb/ft³, and straw ~10 lb/ft³. If you know the area and depth instead, first calculate volume: **Volume = Area × Depth**. Remember that moisture content can increase weight by 30-50%, so account for wet conditions when planning deliveries.
Formula & Method
Weight (lb) = Volume (ft³) × Density (lb/ft³)
Volume (ft³) = Area (ft²) × Depth (ft)
Weight (tons) = Weight (lb) ÷ 2000
