How to Calculate Paver Sand
Calculating the amount of sand for your paver project requires measuring the area and determining the appropriate depth. Here's how the paver sand calculator determines the required amount:
- Measure the area: Multiply the width by the length to get the total square footage.
- Determine the depth: Typically 1 inch of bedding sand is recommended for paver installation.
- Calculate volume: Multiply area by depth to get the total volume needed.
- Calculate weight: Multiply volume by sand density (typically 1,600 kg/m³ or 100 lb/ft³).
The formula is: Volume = Area × Depth and Weight = Volume × Density
Types of Paver Sand
Bedding Sand
Coarse sand used as a base layer beneath pavers. Provides a level surface and allows for drainage. Typically applied at 1 inch depth.
Polymeric Sand
Fine sand mixed with polymers that hardens when wet. Used to fill joints between pavers. Prevents weed growth and insect intrusion.
Leveling Sand
Fine-textured sand used for creating a smooth, level surface. Essential for proper paver alignment and stability.
Installation Tips
- • Add 5-10% extra sand to account for compaction and waste during installation.
- • Use washed concrete sand for the bedding layer to ensure proper drainage.
- • Compact the sand base thoroughly before laying pavers to prevent settling.
- • Keep the sand layer between 0.75 to 1.5 inches for optimal support.
- • For polymeric sand, follow manufacturer instructions for proper activation and curing.

Frequently Asked Questions
How much sand do I need under pavers?
Typically, you need a 1-inch layer of bedding sand beneath pavers. For a 100 square foot area, this translates to approximately 0.83 cubic yards or 22.5 cubic feet of sand.
What type of sand is best for paver base?
Coarse, washed concrete sand is ideal for the paver base. It provides excellent drainage, compaction, and stability. Avoid using fine mason sand for the base layer.
How do I calculate polymeric sand for joints?
Polymeric sand calculations depend on joint width and paver thickness. Generally, a 50 lb bag covers 75-100 square feet with standard joint widths. Check manufacturer specifications for precise coverage.
Should I compact sand before laying pavers?
Yes, compact the base material thoroughly, but leave the final 1-inch bedding sand layer loose for screeding. After placing pavers, compact the entire surface with a plate compactor.
