Paver Calculator
Calculate required pavers, 4 in base gravel volume, and 1 in bedding sand for patios, walkways, and driveways.
- 132 × pavers (12" × 12") [120 base + 12 cuts]
- 2.07 tons (1.48 cu yd) base gravel (4" depth)
- 0.37 cu yd bedding sand (1" depth)
Standard Project Worked Example (No JavaScript Required)
Baseline Scenario: 10×12 ft patio, 12×12 in pavers, 10% cuts: 120 base pavers + 12 cuts = 132 pavers; base gravel 4 in = 1.48 yd³ (2.07 tons); bedding sand 1 in = 0.37 yd³.

How This is Calculated
Base Pavers = Patio Area / Paver Area. Total Pavers = Base Pavers × (1 + Waste% / 100). Base Gravel (cu yd) = Patio Area × (4/12) / 27. Bedding Sand (cu yd) = Patio Area × (1/12) / 27.
Sourced Reference Constants
- All material yields and bag volumes are derived from official manufacturer technical data sheets.
- Buy quantities are strictly rounded UP to full purchasable units (bags, boxes, sheets, gallons, pavers).
- Waste allowances are user-adjustable to fit complex room alcoves, diagonal patterns, or soil conditions.
Frequently Asked Questions
How much extra paver material should I order for cuts and waste?
Order 10% extra pavers for standard rectangular layouts with straight cuts, and 15% extra for curved perimeters, herringbone, or diagonal patterns.
How deep should paver base gravel and bedding sand be?
Residential paver patios require 4 inches of compacted base gravel topped with a uniform 1-inch layer of uncompacted coarse bedding sand.
How many pavers do I need per square foot?
A standard 12×12 inch paver covers exactly 1 square foot. Standard 4×8 inch brick pavers require 4.5 pavers per square foot.
