Paver Calculator

Divide area by paver area and round up, then add waste. Example: 12×12 inch paver = 1 ft², so a 200 sq ft patio needs 200 pavers before waste. A 4×8 inch paver is 0.222 ft², so the same patio needs 900 pavers (4.5 per ft²). Enter your paver length and width — the calculator does ceil(area ÷ (length × width)) and shows the waste-adjusted count.

Count = 1 ÷ paver area in ft². Common: 12×12 = 1 per ft², 6×12 = 2 per ft², 4×8 = 4.5 per ft², 6×9 = 2.7 per ft². For running bond or herringbone, add 5% extra beyond the 10% rectangular waste because cuts increase. The calculator lets you test 12×12 vs 4×8 instantly.

Patio on soil: 4 inches of compacted crushed base (6–8 inches for driveways). Base volume is area × depth ÷ 27 for cubic yards. For 200 sq ft at 4 inches, that’s 2.47 yd³ before waste, 2.72 yd³ with 10%. Order base as crusher run and size it with the Gravel Calculator if you need tons.

Bedding sand is typically 1 inch (0.083 ft) of concrete sand screeded over the base. Sand yards = area × 0.083 ÷ 27. For 200 sq ft that’s 0.62 yd³, 0.68 yd³ with waste — about 1.5 tons of sand. Don’t use more than 1 inch; excess sand causes settling. Polymeric joint sand is extra and sold by the bag.

10% for a simple rectangle with saw cuts, 15% for curves, circles or diagonal layouts, and add another 5% for herringbone where every edge is a cut. The calculator’s waste multiplies pavers, base and sand together. Keep a few extra pavers after the job for future repairs — dye lots vary.

Split the shape into rectangles, calculate each, and add the totals. The paver count is purely area-based, so an L-shape (e.g., 12×10 plus 8×6) is two runs. If you have a circular pad, use its diameter as length and width and the calculator will slightly overestimate — trim the waste to 10% instead of 15%.

Pavers $3–$6 per sq ft, base gravel $30–$50 per ton, sand $20–$40 per yard, plus edging and polymeric sand. A 200 sq ft patio needs ~220 pavers, 2.7 yd³ base and 0.7 yd³ sand before delivery. Enter your paver price or leave it blank for a quantity-only plan, then compare to a poured concrete slab for the same footprint.
