Paver Sizes Chart: Common Paver and Slab Dimensions

The classic concrete paver in North America is the 4 × 8 in rectangle (the "Holland" or brick shape), and Nicolock calls 2⅜ in (60 mm) the industry-standard thickness. Squares run from 6 × 6 in up to 24 × 24 in, and large slabs go up to 24 × 36 in. In the UK, garden paving slabs are mostly 450 × 450, 600 × 300 and 600 × 600 mm; in Australia, 400 × 400 mm and 600 × 400 mm are standard. The charts below give each size in both units and how many you need per square foot or square metre.

Standard paver sizes in the US and Canada

Nicolock, a US paver maker, lists these as standard sizes in its sizing guide. Many brands sell the same nominal sizes. The count columns allow a ⅛ in joint and 5% for cuts, the same defaults as our paver calculator.

Common paver sizes and how many you need
Size (inches)	Metric	Pavers per sq ft	10 × 10 ft patio	12 × 12 ft patio
4 × 8 in	10 × 20 cm	4.3	452	650
6 × 6 in	15 × 15 cm	3.84	404	581
6 × 9 in	15 × 23 cm	2.58	271	390
8 × 8 in	20 × 20 cm	2.18	230	330
12 × 12 in	30 × 30 cm	0.98	103	149
16 × 16 in	40 × 40 cm	0.55	59	84
18 × 18 in	45 × 45 cm	0.44	47	67
24 × 24 in	60 × 60 cm	0.25	26	38
16 × 24 in	40 × 60 cm	0.37	39	56
20 × 30 in	50 × 75 cm	0.24	25	36
24 × 36 in	60 × 90 cm	0.17	18	25

Sizes are nominal: the actual paver is often a fraction smaller, and many concrete pavers have spacer nibs that set the joint for you. A Belgard Holland paver is sold as 4 × 8 in and 60 mm thick, and the supplier lists 120 sq ft per pallet. Always check the coverage printed on the pallet or product sheet before ordering.

How many 16 × 16 pavers for a 10 × 10 patio?

A 16 × 16 in paver covers 1.78 sq ft. A 10 × 10 ft patio is 100 sq ft, so you need 55.4 pavers with ⅛ in joints, or 59 pavers with 5% for cuts. Step stones and patio squares at 16 × 16 in are sold at US home centres; Pavestone's, for example, is 16 × 16 × 1.75 in. Because 16 in doesn't divide into 10 ft evenly (7½ pavers across), you'll cut a half row on one side unless you adjust the patio size.

A tip from the same arithmetic: if the size is flexible, make the patio a multiple of the paver plus joint. Seven 16 in pavers with ⅛ in joints come to about 9 ft 5 in. Fewer cuts means less waste and a neater edge.

UK paving slab sizes

Garden paving slabs in UK stores come in a few standard sizes. Marshalls' ranges at Wickes, for example, include 450 × 450 mm (32–35 mm thick), 600 × 600 mm (35–38 mm in concrete, 22 mm in Indian sandstone), 600 × 300 mm and 600 × 450 mm. Many are also sold in packs: Wickes lists a Marshalls 600 × 450 × 38 mm slab in packs of 22 covering 5.94 m², and a 600 × 600 × 35 mm slab in packs of 30 covering 10.80 m².

Paving slabs and pavers per square metre (3 mm joint, 5% for cuts)
Size	Per m²	10 m² patio	20 m² patio
200 × 100 mm	47.83	503	1005
400 × 400 mm	6.16	65	130
450 × 450 mm	4.87	52	103
600 × 300 mm	5.47	58	115
600 × 400 mm	4.12	44	87
600 × 450 mm	3.66	39	77
600 × 600 mm	2.75	29	58

The 200 × 100 mm block is the metric twin of the 4 × 8 in paver, used for driveways and herringbone patios. Many patio slabs are laid with a wider mortar joint of 10–15 mm; if yours are, enter that joint in the calculator and the count drops a little.

How many 600 × 400 pavers in a square metre?

One 600 × 400 mm paver covers 0.24 m², so a square metre takes 4.17 pavers laid tight, or 4.12 with 3 mm joints. For a 20 m² patio, that's 87 pavers with 5% for cuts. Adbri's Euro Stone range in Australia comes in this size as well as 400 × 400.

Australian paver sizes

In Australia, the 400 × 400 × 40 mm concrete paver is the everyday patio size. Centenary Landscaping lists Adbri's Euro Classic at 400 × 400 × 40 mm and gives 6.25 pavers per m², which is the tight-laid figure (1 ÷ 0.16). With a 3 mm joint it's 6.16 per m². Adbri also makes 600 × 400 mm in the Euro Stone range, and 200 × 100 mm bricks are common for driveways.

How thick should pavers be?

Paver thickness by use
Use	Thickness	Source
Patio, walkway, foot traffic	At least 2 in; 2⅜ in (60 mm) for heavier foot traffic	Nicolock
Residential driveway	2⅜ in (60 mm)	Nicolock, ICPI
Streets and heavier vehicles	3⅛ in (80 mm)	ICPI
UK concrete patio slabs	32–38 mm	Marshalls (Wickes listings)
Natural stone slabs	About 22 mm	Marshalls Indian sandstone (Wickes)

Thin slabs (35 mm and under) are for patios and paths, not for driving on. Large slabs are thinner for their size, so they suit foot traffic on a well-compacted base. If a car will ever cross it, use a paver rated for vehicles.

How to choose a paver size

Nicolock's guide gives a simple rule based on the size of the space:

Under about 200 sq ft: stay at or below 18 × 18 in, so the pavers stay in proportion to the space.
200 to 400 sq ft: 18 × 18 or 24 × 24 in both work.
Over 400 sq ft: large formats suit the space and mean fewer joints to maintain.

The pattern matters too. Nicolock notes that herringbone needs a rectangular paver, traditionally 4 × 8 or 6 × 9 in, while a grid takes almost any square or rectangle, and a random (ashlar) pattern needs two or three sizes that share a common module. Big pavers on a small patio mean a cut on almost every edge, so you lose more to waste.

Small pavers have more joints. That's more joint sand to buy and more weeding later, but small pavers handle curves, slopes and driveways better.

Pavers per square foot: the formula

Add the joint to each side of the paver: a 16 × 16 in paver with a ⅛ in joint takes up 16.125 × 16.125 in.
Work out that area in square feet: 16.125 × 16.125 ÷ 144 = 1.806 sq ft.
Pavers per sq ft = 1 ÷ that = 0.554.
Multiply by your area, then add 5% for straight patterns or 10% for herringbone and random patterns.

The full chart of pavers per square foot is in our guide to how many pavers per square foot.

Common mistakes

Using the nominal size for a large job. If the real paver is a little smaller, or the joint is wider, your count drifts. Use the coverage on the pallet label for big orders.
Mixing sizes from different brands. A random pattern only works if the sizes share a module, so buy the set from one range.
Choosing thin slabs for a driveway. Patio slabs crack under cars; driveways need 60 mm pavers at least, and 80 mm for heavier vehicles.
Forgetting the base. Whatever the paver size, it sits on gravel and sand. See how much paver base and sand you need.
