Calculate Paver Calculator
Enter project dimensions below to compute required material quantities.
Calculation Results
Calculated using verified construction formula: Pavers = (Length (ft) * Width (ft)) * Pavers Per Sq Ft * (1 + Waste Margin Pct)
Quick Summary
The Paver Calculator computes exact concrete paver piece counts, 1-inch bedding sand volume, 4-inch crushed gravel base volume, 50lb polymeric joint sand bags, total pallet weight, and material cost estimates for patio, driveway, and walkway hardscaping.
- Total Paver Unit Count: Calculates Holland stone (4x8), square (6x6), and large format (12x12) paver pieces.
- Base Layer Sand & Gravel: Itemizes cubic yards of 4-inch crushed stone sub-base and 1-inch bedding sand.
- Polymeric Joint Sand: Computes 50lb bags of polymeric joint sand for weed and ant suppression.
How to Use the Paver Calculator
- Enter Patio / Walkway Length in feet.
- Enter Patio / Walkway Width in feet.
- Select Paver Size (Holland 4 in x 8 in standard).
- Adjust the Waste Margin (%) (10% standard).
- Click Calculate to view total pavers, bedding sand, gravel base, polymeric sand bags, and cost.
Paver Calculator Formula & Method
This tool utilizes verified construction geometric formulas to compute material requirements:
Total Pavers = (Length * Width * Pavers / Sq Ft) * (1 + Waste Margin / 100)
Bedding Sand (yd³) = (Length * Width * 0.0833) / 27
Where:
- Holland Paver (4x8 in): Classic rectangular brick paver yielding 4.5 pavers per square foot.
- Polymeric Sand: Haze-free silica sand coated with polymer binders that harden when wetted with water.
- Crushed Gravel Base: 3/4-inch dense grade aggregate with fines (#21A or CR-6) compacted under sand.
Worked Example
Example: 20ft * 15ft Paver Patio (300 sq ft) with Holland 4x8 Pavers and 10% Waste
- Patio Area: 20 ft * 15 ft = 300 sq ft
- Base Paver Count: 300 sq ft * 4.5 pavers/sq ft = 1,350 pavers
- Total Pavers with 10% Waste: 1,350 * 1.10 = 1,485 Pavers
Applying the formula yields:
Total Pavers Needed: 1,485 Pavers
1-inch Bedding Sand Needed: 0.93 Cubic Yards
4-inch Gravel Base Needed: 3.70 Cubic Yards
Polymeric Joint Sand Bags: 300 / 75 = 4 Bags (50 lb)
Estimated Paver Cost: 1,485 * .25 = ,856.25
What This Calculator Includes vs. Does Not Include
What This Calculator Includes
- Patio & Walkway Hardscape Scoping: Measures concrete pavers, brick pavers, bedding sand, gravel sub-base, and polymeric sand.
- Multi-Layer Excavation Scoping: Calculates 4-inch base aggregate and 1-inch bedding sand depth volumes.
What This Calculator Does Not Include
- Plastic Snap-Edge Restraint Spikes: Metal edge restraint spikes.
Tips & Best Practices
- Compact 4-Inch Sub-Base with a Plate Compactor: Run a mechanical plate compactor over the crushed aggregate sub-base 3 times to prevent future paver sagging.
- Use Coarse Concrete Sand for 1-Inch Bedding Layer: Never use fine mason sand or play sand for the 1-inch bedding layer; coarse washed sand (#8) drains water better.
Common Mistakes to Avoid
- Compacting Bedding Sand Before Setting Pavers: Screed the 1-inch bedding sand flat without tamping; pavers are compacted into the loose sand after setting.
Frequently Asked Questions (FAQ)
How many 4x8 pavers do I need for a 300 sq ft patio?
A 300 sq ft patio requires 1,350 4x8 Holland pavers (1,485 pavers with 10% waste).
How many pavers are in a square foot?
4x8 inch pavers require 4.5 pavers per sq ft; 6x6 inch pavers require 4.0 per sq ft; 12x12 pavers require 1.0 per sq ft.
How much sand and gravel do I need for a 300 sq ft paver patio?
A 300 sq ft patio requires 3.70 cubic yards of crushed gravel base (4 in thick) and 0.93 cubic yards of bedding sand (1 in thick).
How many pavers are on a full pallet?
A standard pallet of 4x8 pavers contains 480 to 500 pavers (approx 105 to 110 sq ft) and weighs ~3,000 lbs.
How many bags of polymeric sand do I need for 300 sq ft?
One 50lb bag of polymeric sand covers 60 to 75 sq ft of pavers with standard 1/8-inch joints (4 bags for 300 sq ft).
How much does a single concrete paver cost?
Standard 4x8 concrete pavers cost between .80 and .00 each (.60 to .00 per sq ft).
How deep should I excavate for a paver patio?
Excavate 7 inches deep: 4 inches crushed gravel base + 1 inch sand bed + 2-3/8 inch paver thickness.
Why is polymeric sand better than regular joint sand?
Polymeric sand hardens like mortar when wet, preventing weed growth and ant burrows between pavers.
