Paver Calculator
Enter your patio size and paver dimensions to get how many pavers to buy, plus the gravel base and bedding sand.

Driveways need a deeper base (6–12"). Add polymeric sand for the joints.
How to estimate a paver patio
Find the area, divide by the square footage of one paver (paver W × L ÷ 144), and add 5–10% for cuts. Below the pavers, plan ~4" of compacted gravel base and ~1" of bedding sand, then polymeric sand in the joints.
Lay out patios and hardscape from a scan
ProBuildCalc turns your iPhone's LiDAR scanner into a job-site measuring kit — walk the space and it captures the square footage, material takeoff, and a blueprint automatically. No tape measure, no graph paper.
Paver calculator FAQ
- How many pavers do I need?
- Divide the patio area (plus ~5% waste) by the square footage of one paver. A 4×8-inch paver is 0.22 sq ft, so a 200 sq ft patio needs roughly 955 of them with waste.
- How much gravel base do pavers need?
- Use a compacted gravel base of about 4 inches for patios and walkways, and 6 to 12 inches for driveways. Above the gravel, lay about 1 inch of bedding sand.
- How much waste should I add for pavers?
- About 5% for a straight or running-bond pattern, and 10% for herringbone, circular, or diagonal layouts that require many cut pieces around the edges.
- What sand goes between pavers?
- Use polymeric sand to fill the joints after laying — it hardens to lock the pavers together and resist weeds and washout. It's separate from the bedding sand underneath.
