Paver Calculator
A patio needs its area divided by the size of one paver, plus 10% for cuts, over a 4-inch gravel base and 1-inch sand bed. Enter your sizes to get pavers, base, and cost.
How to estimate pavers
Find the area by multiplying length by width, then divide by the area of one paver. Add 10% for the cuts around edges and curves. For an irregular patio, total the sections with the square footage calculator.
Gravel base and bedding sand
A paver patio sits on a 4-inch compacted gravel base topped with 1 inch of bedding sand. The calculator turns those depths into cubic yards so you can order aggregate. Need just the volume of a fill? Use the cubic yard calculator.
Paver cost
Multiply pavers by the unit price. Concrete pavers run $2–$6 each; clay and natural stone cost more. Remember to budget separately for the gravel, sand, and edge restraints.
Frequently asked
How many pavers do I need?
Divide your patio area by the square footage of one paver, then add 10% for cuts and breakage. A 100 sq ft patio with 12×12 in pavers needs about 110 pavers.
How much gravel base goes under pavers?
A 4–6 inch compacted gravel base is standard for patios and walkways; driveways need 8–12 inches. The calculator returns the base volume in cubic yards.
How much bedding sand do pavers need?
A 1-inch layer of bedding sand sits between the gravel base and the pavers. The calculator converts that depth across your area into cubic yards.
