Bulk Yard Volume Calculator

Calculate how much material you need for common spaces (beds, driveways, circles, triangles). Outputs cubic yards (yd³) plus optional “Super Sack” count and approximate weight.

1) Choose material + shape

Material (Bulk Yard)

Density affects the weight estimate (kg/m³ approx.).

Waste / Overfill

Adds a buffer for spillage/compaction.

Space shape

Measurement units

You can swap units anytime.

Length

Width

Depth

Tip: Mulch often 2–4 in. Rock commonly 2–6 in.

Depth input

Choose how your depth number is interpreted.

“Super Sack” volume (yd³ each)

If your sack size differs, change this value.

Weight estimate

Based on typical densities (varies with moisture/compaction).

Tip: If you’re building up (topsoil/triple mix), calculate loose volume. If you’re compacting (base gravel/crusher dust), consider 10–15% extra for waste/compaction.
