How deep should mulch be?

For optimal weed suppression and moisture retention, standard landscaping mulch should be applied at a depth of 2 to 3 inches.

How much does a yard of topsoil weigh?

One cubic yard of dry topsoil weighs approximately 2,200 pounds (1.1 tons), while gravel can weigh up to 2,800 pounds (1.4 tons).

What is the formula for calculating cubic yards?

Multiply the length by width in feet, multiply by the depth in feet (inches divided by 12), and then divide the final total by 27.

Pro Tip: If buying in individual bags, 1 Cubic Yard is equivalent to roughly 27 standard 1-cubic-foot bags.

How to Use the Material Estimator

Estimating landscape materials correctly helps prevent overspending or running out of supplies mid-project. Follow these simple steps to calculate exact quantities:

Select your unit preference: Switch between Imperial (feet/inches) and Metric (meters/cm) at the top of the calculator.
Choose your material: Select whether you are purchasing mulch, topsoil, or gravel. Each material has a distinct density affecting overall weight.
Enter dimensions: Measure and input the total length, width, and desired depth of your coverage area.
Review results: The calculated volume and total weight update instantly to help you place orders with your supplier.

Frequently Asked Questions

How deep should my material be spread?

Standard recommendations vary by application:
• Mulch: 2 to 3 inches (prevents weeds while retaining moisture).
• Topsoil: 4 to 6 inches for brand-new lawns; 2 to 3 inches for flower beds.
• Gravel: 2 to 4 inches depending on driveway or path traffic.

Why does weight vary between materials?

Material density varies significantly. Mulch is porous and light (~0.4 tons/yd³), topsoil contains moisture and organic matter (~1.1 tons/yd³), and crushed gravel consists of dense stone (~1.4 tons/yd³). Note that wet materials can weigh substantially more.

How much extra material should I order?

It is good practice to add 5% to 10% extra to your calculated total to account for ground settling, uneven surfaces, or compaction during installation.
