About Paver Calculator

The Paver Calculator estimates the number of pavers, bedding sand, joint sand, and gravel base material needed for patio, walkway, and driveway projects. Enter your area dimensions, choose a paver size and laying pattern, and get an instant materials list with quantities in cubic yards, bags, and tons — ready for your next trip to the supply store.

What Is a Paver Calculator?

A paver calculator is a project planning tool that converts your area measurements and paver dimensions into exact material quantities. Instead of manually computing how many pavers fit in your space — and guessing how much sand and gravel to buy — the calculator handles the math, including waste factors for different laying patterns and edge cuts.

Key Formulas

Pavers Needed
Pavers = (Area ÷ Paver Area) × (1 + Waste%)

Sand Volume
Sand (cu yd) = Area (sq ft) × Depth (in) ÷ 12 ÷ 27

Gravel Volume
Gravel (cu yd) = Area (sq ft) × Depth (in) ÷ 12 ÷ 27

How to Use This Calculator

Enter Area Dimensions — Measure your patio, walkway, or driveway and enter the length and width in feet or meters.
Select Paver Size — Choose from preset sizes (Standard Brick, Holland, Large Rectangle, Square, Cobblestone) or enter custom dimensions.
Choose Laying Pattern — Pick Running Bond, Herringbone, Basketweave, or Stacked Bond. Each pattern has a different waste factor.
Adjust Advanced Settings — Fine-tune joint width, extra waste percentage, gravel base depth, and sand bedding depth.
Click Calculate — Review the complete materials breakdown including a printable shopping list.

Paver Sizes Guide

Paver Type	Size (L×W×T)	Per Sq Ft	Best For
Standard Brick	8″ × 4″ × 2¼″	~4.5	Patios, walkways
Holland Paver	8″ × 4″ × 2⅜″	~4.5	Driveways, high-traffic
Large Rectangle	9″ × 6″ × 2⅜″	~2.7	Modern patios
Square 6×6	6″ × 6″ × 2⅜″	~4	Borders, accents
Square 12×12	12″ × 12″ × 2⅜″	1	Large patios, pool decks
Cobblestone	4″ × 4″ × 2¼″	~9	Garden paths, rustic look

Laying Patterns Explained

Running Bond (~5% waste) — The most popular pattern. Pavers are laid in staggered rows like a brick wall. Easy to install and structurally strong.
Herringbone (~10% waste) — Pavers interlock at 45° or 90° angles, creating a zigzag pattern. Excellent for driveways as it resists shifting under load.
Basketweave (~5% waste) — Pairs of pavers alternate between horizontal and vertical orientation. Creates a woven look ideal for patios and courtyards.
Stacked Bond (~2% waste) — Pavers align in straight rows and columns. Modern, clean look but less interlocking strength. Best for patios and decorative areas.

Base Preparation Guide

Proper base preparation is crucial for long-lasting paver installations. The typical installation layers from bottom to top:

Compacted Soil — Excavate to the required depth and compact the native soil with a plate compactor.
Gravel Base (4–8″) — Use crushed stone (¾″ minus) and compact in 2-inch lifts. Use 4 inches for patios and 6–8 inches for driveways.
Bedding Sand (1″) — Spread coarse concrete sand and screed to a uniform 1-inch depth. Do not compact before laying pavers.
Pavers — Lay pavers in your chosen pattern, maintaining consistent joint spacing.
Joint Sand — Sweep polymeric sand into joints and mist with water to activate the binding agent.

Frequently Asked Questions

How many pavers do I need per square foot?

It depends on paver size. Standard 4×8 inch brick pavers require about 4.5 pavers per square foot. Larger 12×12 inch pavers need 1 per square foot. This calculator automatically determines the count based on your chosen paver size and area.

How thick should the gravel base be for pavers?

For pedestrian areas like patios and walkways, a 4-inch compacted gravel base is standard. For driveways or areas with vehicle traffic, use a 6 to 8 inch base. The gravel should be compacted in 2-inch lifts for best results.

Which paver pattern wastes the least material?

Stacked Bond wastes the least material at about 2% because pavers align in straight rows with minimal cutting. Running Bond adds about 5% waste, Basketweave about 5%, and Herringbone about 10% due to the angled cuts needed at edges.

How much sand do I need under pavers?

A 1-inch layer of coarse bedding sand is standard under pavers. For a 100 square foot patio, this equals about 0.31 cubic yards or roughly 8 bags of 50-pound sand. You also need joint sand to fill gaps between pavers.

What is the difference between bedding sand and joint sand?

Bedding sand is the 1-inch layer placed on top of the gravel base to create a smooth, level surface for laying pavers. Joint sand, often polymeric sand, is swept into the gaps between pavers after installation to lock them in place and prevent weed growth.
