Paver Calculator
Enter your patio or walkway dimensions and paver size to get the paver count — plus the base gravel, bedding sand, and joint sand for a full install.
Patios need about 4″ of compacted base; driveways 6–8″.
About 50 lb per 100 sq ft with narrow joints.
How it works
We divide your project area by the face area of one paver, then add your waste margin for edge cuts and breakage. Base gravel uses your selected depth, bedding sand is a standard 1-inch screed layer, and joint sand assumes roughly 50 lb per 100 square feet.
Formula: Pavers = ceil(Area ÷ paver sq ft × (1 + waste)); Base = Area × depth÷12 ÷ 27
Good for
- Patios and outdoor seating areas
- Walkways and garden paths
- Driveways (use the 8″ base option)
- Pool surrounds
Tips
- Straight patterns (running bond) need ~10% waste; herringbone and diagonals need 15–20%.
- Order every paver from the same production batch — colors shift between batches.
- Compact the gravel base in 2–3″ lifts; skipping compaction is the top cause of sunken pavers.
- Keep bedding sand at exactly 1″ — deeper sand shifts under load.

How many pavers do I need for a 12×10 patio?
A 12×10 ft patio is 120 sq ft. With 4×8″ brick pavers (0.22 sq ft each) and 10% waste, you need about 595 pavers. With 12×12″ pavers you need about 132.
How deep should the base be under pavers?
Use about 4 inches of compacted gravel plus 1 inch of bedding sand for patios and walkways. Driveways carrying vehicles need a 6–8 inch compacted base.
What is polymeric sand?
A sand-and-binder blend swept into the joints and misted with water. It hardens to lock pavers together, resist weeds, and stop washout — plan on roughly one 50-lb bag per 100 sq ft with narrow joints.
Why order extra pavers?
Edge cuts, breakage, and future repairs. Matching a discontinued color years later is nearly impossible, so keep a few spares from the same batch.
