Paver Calculator: The Complete Guide to Estimating Pavers, Base Materials, and Cost

Pavers create beautiful, durable outdoor surfaces for patios, walkways, driveways, and pool decks. Unlike poured concrete, individual pavers flex with ground movement without cracking, can be easily replaced if damaged, and offer hundreds of pattern and color options. Getting the material quantities right is essential — running short mid-project is frustrating, and most suppliers charge restocking fees on returns.

The Paver Formula

Area = Length × Width (sq ft)
Pavers Needed = Area × Pavers per Sq Ft
With Pattern Waste = Pavers × (1 + Waste%)
Gravel Base = Area × Depth (ft) ÷ 27 = cubic yards
Leveling Sand = Area × 1" (0.083 ft) ÷ 27 = cubic yards
Polymeric Sand = Area ÷ 60 = bags (50 lb)
Edge Restraint = Perimeter in linear feet
Worked Example — 16×12 ft Patio with 4×8 Pavers
Area: 16 × 12 = 192 sq ft
Pavers: 192 × 4.5/sq ft = 864 pavers
Herringbone 90° waste (+10%): 864 × 1.10 = 951 pavers
Gravel (6" base): 192 × 0.5 ÷ 27 = 3.56 cu yd
Leveling sand (1"): 192 × 0.083 ÷ 27 = 0.59 cu yd
Polymeric sand: 192 ÷ 60 = 3.2 → 4 bags
Edge restraint: 2×(16+12) = 56 linear feet
Paver cost: 951 × $1.50 = $1,427 for pavers

Base Preparation — The Foundation of Every Paver Project

The gravel base is the most important element of any paver installation. Patios and walkways need 4–6 inches of compacted 3/4-inch minus crushed gravel. Driveways require 8–12 inches for vehicle loads. Compact in 2-inch lifts using a plate compactor, wetting each lift before compacting. Over the compacted gravel, spread exactly 1 inch of coarse leveling sand (not play sand) and screed it smooth using pipe rails and a straight board. Never compact the leveling sand — it should remain loose so pavers can be set to precise grade.

Pro Tip — Slope for Drainage
All paver surfaces must slope away from structures at a minimum of 1/8 inch per foot (1% grade). For patios adjacent to a house, slope away from the foundation. For walkways, slope to one side. For pool decks, slope away from the pool and toward landscape drains. Establish the slope in the gravel base, not in the sand layer. Standing water on pavers promotes algae growth, efflorescence, and freeze-thaw damage.
Critical — Don't Skip Edge Restraint
Edge restraint is not optional. Without it, pavers at the edges shift outward over time, joints open up, and the entire surface eventually fails. Install aluminum L-channel or plastic paver edging against the compacted gravel base, staked every 12 inches with 10-inch spikes. Install edge restraint BEFORE laying pavers. For curves, use flexible edging scored on the back side. Some municipalities require edge restraint for paver permit approval.

Polymeric Sand: Why It Matters

After laying and compacting pavers, fill joints with polymeric sand — not regular sand. Polymeric sand contains polymer binders that activate with water, creating a firm, flexible joint that prevents weed growth, resists insect infiltration, and withstands rain washout. Sweep sand into all joints, remove excess from paver faces, then mist with water in a specific pattern per manufacturer instructions. One 50 lb bag covers approximately 50–75 sq ft depending on joint width. Reapplication may be needed every 3–5 years.

Frequently Asked Questions

How many pavers do I need per square foot?
4×8": 4.5/sq ft. 6×6": 4/sq ft. 6×9": 2.67/sq ft. 6×12": 2/sq ft. 12×12": 1/sq ft. These include standard 1/8" joint spacing. Add 5-15% for pattern waste (herringbone uses more than running bond). Our calculator handles all sizes and patterns automatically.
How much does a paver patio cost?
Materials: $6-$12/sq ft (pavers + base + sand). Professional installation: $10-$25/sq ft total. A 12×16 patio (192 sq ft): $1,200-$2,300 DIY, $2,000-$4,800 installed. Natural stone: $15-$35/sq ft. Permeable pavers: $8-$15/sq ft. Prices vary by region, paver material, and pattern complexity.
How much sand and gravel for pavers?
Gravel base: 4-6" for patios, 8-12" for driveways. 200 sq ft patio with 6" base ≈ 3.7 cu yd gravel. Leveling sand: 1" deep = 0.6 cu yd per 200 sq ft. Polymeric sand: 1 bag per 50-75 sq ft. Use 3/4" minus crushed gravel (not river rock) and coarse leveling sand (not play sand).
What is the best paver pattern?
Running bond: easiest, least waste (5%). Herringbone: strongest for driveways, interlocks under load (10-15% waste). Basketweave: classic look, moderate difficulty (8%). For driveways always use herringbone. For patios any pattern works — choose based on aesthetics. Diagonal patterns use more waste than straight.
How thick should the base be?
Patios/walkways: 4-6" compacted gravel + 1" leveling sand. Driveways: 8-12" gravel + 1" sand. Pool decks: 6" gravel + 1" sand. Compact gravel in 2" lifts with a plate compactor. The base is the foundation — 95% of paver failures are from poor base preparation, not the pavers themselves.
Do I need edge restraint?
Yes, always. Without edge restraint, pavers shift and separate over time. Use aluminum L-channel ($1-$2/ft) or plastic edging ($0.50-$1/ft), staked every 12". Install before laying pavers. For curves use flexible edging. Edge restraint is code-required in many areas and essential for long-term stability.
What is polymeric sand?
Joint sand with polymer binders that harden when wet, locking pavers together. Prevents weeds, insects, and rain washout. $20-$30/bag covering 50-75 sq ft. Strongly recommended over regular sand. Apply after pavers are laid and compacted, then mist with water to activate. Reapply every 3-5 years.
