Pea gravel coverage calculator guide

Choose a realistic depth

Pea gravel quantity depends heavily on the finished depth. Decorative borders and paths can need different depths.

• Measure the finished area after edging is planned.
• Choose depth based on use, not only appearance.
• Use the pea gravel preset as a starting density estimate.

Compare bag and bulk options

Small bags are simple for small areas, while bulk bags or loose loads can make more sense for larger projects.

• Enter the actual bag size from the supplier.
• Compare kg and tonnes against bulk-bag listings.
• Check delivery access before choosing a loose load.

Garden path gravel depth and quantity guide

Estimate path gravel by measuring the finished route and choosing a practical depth.

Measure the actual route

A path may curve, narrow, or widen, so split it into simpler sections before calculating area.

• Measure straight sections separately.
• Use average width for gentle curves.
• Exclude fixed steps, drains, or edging.

Depth depends on the build-up

The calculator estimates the gravel layer after you choose a depth, but the path may also need membrane, edging, or base preparation.

• Confirm whether the path is decorative or high-traffic.
• Allow for settling and uneven ground.
• Ask a supplier or landscaper for load-bearing projects.

Path depth checks

The path depth checks reference keeps the relevant comparisons together so each assumption can be checked before changing the calculator inputs.

• Path condition: Light decorative use; Depth impact: May use a shallower layer; Action: Still hide membrane and base.
• Path condition: Regular foot traffic; Depth impact: Needs more consistent coverage; Action: Check edging and settlement.
• Path condition: Curved route; Depth impact: Area is harder to measure; Action: Split into sections or use average width.
