Paver Patio Calculator

Pavers, base gravel and bedding sand in cubic yards, joint-sand bags, and edge restraint — from your patio size and paver dimensions.

Frequently asked

FAQ

How many pavers do I need?
Divide the patio area by one paver's area, then add 5–10% for cuts and breakage — 5% for a simple running bond, 10% for herringbone or diagonal layouts. The calculator rounds up to whole pavers.
How deep should the base be?
Use 4 inches of compacted gravel for a light pedestrian patio on dry soil, 6 inches for typical and freeze-thaw soils (the default), and 8–12 inches for anything bearing vehicle weight. Over a 1-inch bedding-sand layer.
Why buy extra gravel?
The cubic-yard figures are for the finished, compacted depth. Crushed gravel compacts roughly 15–20% during installation, so order about 20% more than the calculated volume so you don't come up short.
