Pavers per Square Foot

Pavers per square foot = 144 ÷ (paver length × paver width), with both in inches, because a square foot is 144 square inches. A 4 × 8 brick paver gives 4.5 per square foot, a 6 × 9 gives 2.67 and a 12 × 12 gives exactly 1. If your paver is smaller than its nominal size and you leave a joint, add the joint to each dimension. PaverCalc starts this page with 6 × 9 pavers over a known area.

Most concrete paver sizes are nominal and already include the narrow joint formed by the spacer bars, so leave the joint at 0 unless the actual size is smaller.

How the paver calculator works

PaverCalc finds the area of the rectangle (length × width), circle (π × radius²) or the area you enter, then multiplies it by the pavers per square foot, 144 ÷ ((paver length + joint) × (paver width + joint)), and adds your waste allowance, rounding up to whole pavers.

The base area is the paver area extended by the base extension on every side. Base volume = base area × depth, plus the compaction allowance, converted to tons with the density you set. Bedding sand = paver area × sand depth. Joint sand bags = area ÷ coverage per bag. Edge restraint = the perimeter.

Paver (inches)	Pavers per sq ft	Sq ft per paver
4×8 brick paver	4.5	0.22
6×6	4	0.25
6×9	2.67	0.38
6×12	2	0.5
12×12	1	1
12×24	0.5	2
16×16	0.56	1.78
24×24	0.25	4

Typical layers (ICPI guidance)

Layer	Patio / walkway	Driveway
Compacted aggregate base	4″ minimum	6″ minimum
Bedding sand	1″ nominal	1″ nominal
Paver thickness	2⅜″ (60 mm) or more	2⅜″ (60 mm) or more; herringbone pattern
Base past the edges	6″ or more	6″ or more

Base and sand guidance from the Interlocking Concrete Pavement Institute (ICPI) for well-drained soils; use a thicker base on clay, wet or frost-prone ground. Densities (about 1.4 tons/yd³ for crushed base, 1.3 for sand) and joint-sand coverage are typical figures, so results are estimates: confirm with your supplier and the bag label, and call 811 (US) before you dig.

Frequently asked questions

How many 4 × 8 pavers per square foot?

4.5 pavers.

How many 12 × 12 pavers per square foot?

One. A 16 × 16 covers 1.78 sq ft (0.56 per sq ft) and a 24 × 24 covers 4 sq ft.

How do I count pavers sold by the square foot?

Many suppliers sell pavers by the square foot or by the pallet with its coverage printed. Divide your area plus waste by that coverage.

Is PaverCalc free?

Yes, with no sign-up or ads.

Are my measurements saved?
