Paver Calculator
Enter your patio or walkway dimensions and get real paver counts, plus the gravel base and sand bed underneath.
Standard trade advice is 10% extra for cuts, breakage, and pattern layout.

- This calculator already includes a setting bed, but a thicker bed on soft ground needs more sand than the default; the sand calculator sizes that layer on its own. Sand Calculator
- For a brick border or edging around the same patio, the brick calculator counts units and mortar the same way this one counts pavers. Brick Calculator
Frequently Asked Questions
How deep should the base be under pavers?
A 4-6 inch compacted gravel base plus a 1 inch sand setting bed is the standard recommendation across most paver manufacturers' installation guides -- heavier traffic (a driveway vs. a garden path) generally calls for the deeper end of that range.
Why does the paver count include a waste factor?
Cuts around edges and curves, breakage during handling, and pattern layouts (like herringbone) that don't tile perfectly all use more pavers than the raw area math suggests. 10% is standard trade advice for most layouts; simple grid patterns can sometimes get away with less.
Can I use this for irregular-shaped patios?
This calculator assumes a rectangular area. For an irregular shape, break it into rectangular sections, run each through the calculator separately, and add the results together.
Do pavers need polymeric sand in the joints?
It's not strictly required, but it's standard practice -- polymeric sand hardens when watered and locks pavers in place, resists weed growth and ant nests, and slows joint erosion far better than plain sand. Skipping it saves a bit of money up front but usually means re-sanding joints within a year or two.
