Paver Calculator

Free patio paver calculator for patios, walkways, and driveways. Calculate total 4x8 or square pavers needed, crushed stone base gravel (tons), bedding sand, and polymeric joint sand.

How many pavers, plus base gravel and joint sand?

Pavers are area ÷ piece size, plus waste (10%+). Under them, US DIY patios usually want a compacted crushed-stone base and a bedding sand layer. Polymeric joint sand is sold by the bag with coverage that depends on joint width.

Why the base is most of the truck

A 12×12 patio at 4 in of base is a lot of stone (see gravel). Skipping compaction is how patios sink. This calculator’s stone and sand numbers are planning quantities — follow the paver maker’s cross-section if they publish one.

Frequently Asked Questions

How many 4x8 pavers do I need for a 10x10 patio?
A 10×10 patio is 100 square feet. Each standard 4"×8" brick paver is 0.222 sq ft (requiring 4.5 pavers per sq ft). With a **10% cutting and waste factor**, you need **495 pavers** (approx. 450 net + 45 for cuts).
How deep should the gravel base be under pavers?
For residential pedestrian patios and garden walkways, install a minimum of **4 inches of compacted crushed stone gravel base** (such as 3/4" crusher run / road base). For driveways or heavy vehicular loads, increase gravel depth to **8 to 10 inches**.
How much bedding sand do I need for a paver patio?
Lay a uniform **1-inch layer of coarse concrete sand** directly on top of the compacted gravel base. For a 100 sq ft patio, this requires about **0.31 cubic yards (approx. 0.42 tons)** of bedding sand. Never compact bedding sand before laying pavers.
How many bags of polymeric sand do I need?
One 50-pound bag of polymeric joint sand covers approximately **50 to 75 square feet of standard brick pavers** (with 1/8" to 1/4" joints). For larger slab pavers with fewer joints, one bag can cover up to 100 sq ft.
