Paver Calculator: How Many Pavers Do I Need?
Enter your patio or walkway size and paver dimensions for an instant count of how many pavers to buy — for any paver size and laying pattern, with waste for cuts built in.
Paver Calculator
Enter your patio or walkway size and the paver dimensions. The calculator tells you how many pavers to buy, with waste for cuts included — for any paver size.
How to use this paver calculator
Enter the length and width of the area in feet, then your paver width and length in inches. Pick the layout to set a realistic waste factor, and add any extra area (for an L-shape or curve) under Advanced. The calculator returns the total number of pavers to buy.
How much waste for cuts and patterns?
The simpler the layout, the less you cut. A straight running bond wastes about 5%, a diagonal layout about 10%, and herringbone or intricate patterns up to 15%. Curved borders and circular features waste more still — when in doubt, round up, since matching pavers later can be hard.
Don't forget the base
The pavers are only half the order. A lasting patio sits on about 4–6 inches of compacted gravel topped with roughly 1 inch of bedding sand, over landscape fabric. That base is what keeps pavers from sinking and heaving. Size the gravel and sand with the gravel & aggregate calculator before you order.
Buy from one lot — and keep spares
Pavers are made in batches, and color shifts between them. Buy your whole job at once from a single lot, and set aside a few extras. A handful of spare pavers from the matching batch makes a future repair invisible instead of an obvious patch.
Frequently asked questions
How many pavers do I need for a 12×10 patio?
A 12 ft × 10 ft patio is 120 sq ft. With 12×12 inch pavers (1 sq ft each) and 5% waste for cuts, that is about 126 pavers. Smaller pavers mean more pieces — the calculator works it out from your paver size.
How much waste should I add for pavers?
About 5% for a straight running-bond layout, 10% for diagonal, and up to 15% for herringbone or other patterns that need lots of angled cuts. Rounded edges and curves also push waste higher, so round up if your patio is not a simple rectangle.
How do I calculate a different paver size?
Enter the paver width and length in inches and the calculator converts to square feet (width × length ÷ 144), then divides your area by it. That covers everything from small clay bricks to large-format slabs.
What base do I need under pavers?
A typical patio needs about 4–6 inches of compacted gravel base topped with about 1 inch of bedding sand, over landscape fabric. Use the gravel calculator to size the base material — skipping or skimping on it is the main cause of sunken, uneven pavers later.
Should I buy extra pavers?
Yes. The waste factor covers cuts, but it is also smart to keep a handful of spares from the same production lot. Paver color varies between batches, so a future repair with a fresh batch can stand out.
How do I handle a curved or L-shaped patio?
Break the shape into rectangles, add up their square footage, and enter the total (the Advanced "extra area" box helps). Then bump the waste factor up a notch, because curves and angles produce more offcuts.
