How to Calculate Decorative Stones for Your Landscaping Project

How to Calculate Decorative Stones for Your Landscaping Project

Planning your stone order carefully prevents costly mistakes. Follow this simple guide to estimate exactly how much material you'll need.

Step 1: Measure Your Space

  • For ground coverage: Calculate area (length × width) in square meters

  • For gabion walls: Calculate volume (length × height × depth)

Step 2: Choose Your Depth

  • Pathways: 5-7 cm

  • Ground cover: 2-3 cm

  • Gabions: Match cage dimensions

Step 3: Quantity Calculation

General rule:

  • 1 ton = covers 12m² at 5cm depth

  • 20kg bag = covers 0.5m² at 5cm depth

Example:
A 10m² pathway at 5cm depth requires:
10m² ÷ 12m²/ton = 0.83 tons (~850kg)

Key Considerations

 Add 10% extra for waste/spillage
 Irregular stones require more volume
 Sloped areas need additional material
