Mulch Calculator
Enter bed dimensions and desired depth to estimate mulch volume.
$
Step 1: Depth(ft) = Depth(in) / 12
Step 2: Volume(ft3) = Length * Width * Depth(ft)
Step 3: Cubic Yards = Volume(ft3) / 27
10*12 ft at 3 in -> 10*12*0.25 / 27 ~= 1.11 yd3.
What depth should I use?
Maintenance: 2–3 inches. New beds/weed suppression: 3–4 inches. Deeper layers reduce evaporation and weeds but cost more.
How many cubic yards per truck load?
Varies by truck. A common small dump truck carries ~5–10 yd³. Confirm with your supplier.
Should I account for settling?
Yes. Mulch settles over time—consider adding 5–10% extra for compaction and losses.
Does color or type affect coverage?
Density differs slightly by mulch type (hardwood, pine bark, rubber). This tool uses volume; coverage per yard is similar across types.
What depth should I use?
Common mulch depths: 2–3 inches for maintenance; 3–4 inches for new beds or weed suppression.
