How do I calculate how many pavers I need?

Divide the area by the area of one paver, then add waste. A 4 × 8 in paver covers 32 sq in, 0.222 sq ft, so a 12 × 16 ft patio (192 sq ft) takes 192 ÷ 0.222 = 864 pavers, and 951 with 10% for cuts and breakage.

How many pavers are in a square foot?

4.5 for a 4 × 8 in paver: a square foot is 144 sq in and the paver covers 32. With a 1/8 in joint each paver takes up a little more room, and the count drops to 4.30 per sq ft. A 12 × 12 in paver covers 1 sq ft, so a 10 × 10 ft patio takes 100, and 110 with 10% waste; a 12 × 24 in paver covers 2 sq ft, a 16 × 16 in paver 1.78 and a 24 × 24 in paver 4.

How much extra should I order for the paver pattern?

Inch Calculator gives 10% for running bond, 10% for basket weave, 10% for 90° herringbone, 20% for 45° herringbone; its paver calculator page adds that a diagonal layout needs at least 20% more. Curves, many corners and a circle cut more pavers, so go higher there.

How many square feet of pavers are on a pallet?

78 to 160 sq ft, by Inch Calculator, depending on the paver's size and shape. Type the coverage on your supplier's pallet and the calculator gives whole pallets; without it, it shows the range.

What size and thickness are concrete pavers?

Common faces are 4 × 8, 6 × 6, 6 × 9, 12 × 12, 12 × 24, 16 × 16 and 24 × 24 in, the calculator's presets. For thickness, Concrete Network gives 2 3/8 in for residential patios, walkways and driveways, 3 1/8 in for streets and industrial paving, and about 1 1/4 in for thin pavers laid over an existing slab.

How do I calculate pavers for a circle or an L-shaped patio?

Pick Circle and type the diameter: a 12 ft circle is 113.1 sq ft, 611 pavers of 4 × 8 in with 20% waste for the cuts. For an L shape, pick Several areas and type it as two rectangles.

How much edge restraint do I need?

The length of every edge that doesn't sit against a wall or a slab: the calculator gives the whole perimeter (2 × (length + width), or π × diameter), so take off the sides along the house. With several areas, it adds each rectangle's perimeter, so take off the sides they share.

Paver Calculator

A 12 × 16 ft patio of 4 × 8 in pavers takes 951 pavers with 10% waste, 4.5 per square foot. Enter the area as a rectangle, a circle or several areas added together, then the paver size, the joint and the laying pattern: you get the pavers to buy, the pallets, the weight in pounds and tons, the edge restraint length and the cost at your price.

How HomeMath counts pavers

HomeMath works out the area in square feet (a circle is π × radius²; several areas are added), then the area one paver covers: its length plus the joint × its width plus the joint, in inches, ÷ 144. The area ÷ that is the pavers without waste; the pattern's waste is added and the count rounded up to whole pavers. The waste starts at Inch Calculator's figure for the pattern: running bond 10%, basket weave 10%, 90° herringbone 10%, 45° herringbone 20%. A paver's weight is its length × width × thickness at 150 lb per cubic foot, solid concrete's weight, and the pallets are the area with waste ÷ the pallet's coverage, rounded up. The edge restraint runs around the outside: 2 × (length + width) for a rectangle, π × diameter for a circle; with several areas each area's perimeter is added, so take off the sides they share. In metric, the area is in square meters, the pavers sized in centimeters, the edge restraint in meters, and the weight in kilograms and tonnes.

The published rules it uses: US customary units; metric conversion; paver counts, waste and weight. Their sources, and how HomeMath tests every result, are on the about page.

How many pavers fit in a square foot, by paver size?

A square foot is 144 sq in, so pavers per square foot are 144 ÷ the paver's face in square inches. The weight is for 2.375 in concrete pavers at 150 lb per cubic foot, the thickness Concrete Network gives for residential patios, walkways and driveways; its 3.125 in street pavers weigh 1.32 times as much.

Per paver size, with 10% waste for the areas
Paver	Per sq ft	Weight each	100 sq ft	12 × 16 ft
4 × 8 in	4.50	6.6 lb	495	951
6 × 6 in	4.00	7.4 lb	440	845

How many 4x8 pavers does a common patio take?

4 × 8 in pavers, 10% waste, pallets of 78–160 sq ft
Area	Pavers	Pallets	Weight	Edging
3 × 20 ft (60 sq ft)	297	1–1	0.98 tons	46 ft
10 × 10 ft (100 sq ft)	495	1–2	1.63 tons	40 ft
12 × 12 ft (144 sq ft)	713	1–3	2.35 tons	48 ft

20 × 20 ft (400 sq ft)	1,980	3–6	6.53 tons	80 ft

A pallet holds 78 to 160 sq ft of pavers, by Inch Calculator, so the pallets are a range until you type your supplier's coverage. Edging is the whole perimeter, less any side along the house. Order the base and sand with the paver base calculator, price the job with the paver cost calculator, and set the fall with the patio slope calculator.

How much extra do the pattern and the joint change?

A pattern changes the cuts at the edges, not the pavers per square foot. The waste starts at Inch Calculator's layout patterns page; its paver calculator adds at least 20% for a diagonal layout. For a 12 × 16 ft patio of 4 × 8 in pavers:

Waste by pattern
Pattern	Waste	Pavers for 192 sq ft
Running bond	10%	951
Basket weave	10%	951
Herringbone, 90°	10%	951
Herringbone, 45°	20%	1,037

The joint works the other way: each paver covers its face plus one joint each way, so a wider joint means fewer pavers. Leave it at 0 when the paver's listed size already includes it, and type it when the maker lists the actual face.

4 × 8 in pavers by joint width
Joint	Per sq ft	12 × 16 ft with 10% waste
None	4.50	951
1/8 in	4.30	908
1/4 in	4.11	868

How do I count pavers by hand?

Area: 12 × 16 = 192 sq ft.
One 4 × 8 in paver: 32 sq in ÷ 144 = 0.222 sq ft.
Pavers: 192 ÷ 0.222 = 864; with 10% waste 951.
Weight: 4 × 8 × 2.375 in ÷ 1,728 × 150 = 6.6 lb each, 3.14 tons in all.
Edging: 2 × (12 + 16) = 56 ft, less any side along the house.

How much do pavers weigh per square foot?

A paver's weight is its volume × the weight of its material. Concrete pavers at 150 lb per cubic foot come to 29.7 lb per square foot at 2 3/8 in and 39.1 at 3 1/8 in. Mixes and makers vary, and brick and stone differ from concrete, so the pallet label is the final word for a delivery.

How many pavers do I need in metric?

Switch to metric for the area in meters and the paver in centimeters, with presets such as 20 × 10, 30 × 30 and 60 × 60 cm, a 6 or 8 cm thickness, and the weight in kilograms and tonnes.
