Sand Coverage & Estimating Guide
How Much Sand Do You Need?
Estimating the correct quantity of sand ensures proper compaction, drainage, and structural performance.
General Coverage Guidelines:
• 1 cubic yard covers approximately 100–120 sq ft at 3 inches deep
• 1 cubic yard covers approximately 150 sq ft at 2 inches deep
• A typical paver patio base may require 1–3 cubic yards depending on size
Because sand compacts differently depending on moisture and application, we recommend measuring:
Length × Width × Depth (in feet)
Then divide by 27 to convert cubic feet into cubic yards.
You can also use our online material calculator or contact us directly for help estimating your project needs.
