Paver Quantity Calculator

Last updated June 2, 2026

Use this paver quantity calculator when the first question is simple: how many pavers do I need? Enter patio size and paver size, then add waste for cuts, borders, breakage, and pattern changes.

Quick answer

Formula: paver quantity = patio area with waste / face area of one paver, rounded up.
A 10x10 patio needs about 495 standard 8x4 pavers with 10% waste.
Use a higher waste allowance for diagonal layouts, curves, borders, or mixed-size patterns.

Paver quantity examples by size

Patio size	Area	8x4 in pavers	6x9 in pavers	12x12 in pavers
10x10 ft	100 sq ft	495	294	110
12x12 ft	144 sq ft	713	423	159
12x16 ft	192 sq ft	951	564	212
16x20 ft	320 sq ft	1,584	940	352

Counts include 10% waste and are rounded up. Use manufacturer face dimensions for the final order.

Paver Material Calculator

One input set for base, bedding sand, polymeric sand, pavers, edging, material cost, and installed estimate.

Imperial Metric

Popular patio sizes:

Patio length (ft) Measure the longest side. Patio width (ft) Use the average width for irregular shapes. Paver length (in) Face dimension of one paver. Paver width (in) Face dimension of one paver.

Advanced settings

Base depth (in) Recommended starting point depends on use. Bedding sand depth (in) A 1 inch screeded bed is common. Joint width (in) Average open joint width. Joint depth (in) Depth filled with polymeric sand. Waste allowance (%) Covers cuts, compaction, and ordering buffer. Base density (tons/cu yd) Supplier density for crushed aggregate. Base bag size (cu ft) Only needed for bag count. Sand bag size (cu ft) Only needed for bag count. Polymeric sand coverage (sq ft/bag) Use the product coverage chart. Paver price ($/sq ft) Set to 0 for quantities only. Base aggregate price ($/ton) Bulk supplier price. Bedding sand price ($/cu yd) Bulk supplier price. Polymeric sand price ($/bag) Retail price per bag. Edge restraint price ($/linear ft) Perimeter edging cost. Labor price ($/sq ft) Set to 0 for DIY material-only estimate.

How to calculate pavers needed

Multiply patio length by patio width to get square footage. Multiply by the waste allowance, then divide by the face area of one paver.

For an 8x4 inch paver, one paver covers 32 square inches, or about 0.22 sq ft. A 100 sq ft patio with 10% waste needs about 495 pavers.

When quantity is not enough

Paver count is only one part of the order. A real patio shopping list also needs compacted base aggregate, bedding sand, polymeric sand, edge restraint, spikes, and sometimes geotextile fabric.

Use the full material estimator when you want quantity, base, sand, bags, edging, and cost together.
