How to Calculate the Right Amount of cobblestones or Cobblestones for Your Project

Figuring out exactly how much pebble, gravel, or decorative stone you need is simpler than it sounds. Follow these four steps to avoid over-ordering — or running short mid-project.

Step 1 — Measure your space

Measure the length and width of the area you want to cover. Multiply the two figures to get the surface area in square metres (m²). Example: 10 m × 7 m = 70 m².

Step 2 — Choose your layer depth

The right depth depends on the size of the material:

• Fine cobblestones (1–3 cm): A layer of 4–5 cm is sufficient.
• Coarse cobblestones (6–7 cm): You'll need a depth of at least 10 cm for a visually appealing, stable finish.

Step 3 — Calculate cubic metres

Convert the depth to metres (e.g. 6 cm = 0.06 m), then multiply:

70 m² × 0.06 m = 4.2 m³

Step 4 — Convert to tonnes

Multiply the cubic metres by the specific weight of the material. For most types of cobblestones and gravel, this is approximately 1.5 tonnes/m³:

4.2 m³ × 1.5 = 6.3 tonnes

Pro tip: Always add 5–10% extra to account for losses during installation and spreading. For gardens, patios, pathways, and planting borders, fine gravel offers excellent coverage and helps retain soil moisture, while coarse cobblestones create a bold, high-impact decorative effect.
