Short answer: Australian tile size guides list anywhere from three to two dozen sizes, and the one every guide we read lists is 600 × 600 mm. This range is made in five of those sizes — 600 × 600 mm (thirty-four tiles), 300 × 600 mm (nineteen), 600 × 1200 mm (twelve), 75 × 300 mm (nine) and 100 × 300 mm (two) — plus twelve mosaics on nine sheet sizes. Several sizes the guides list are not made here at all: 300 × 300, 450 × 450, 400 × 400, 800 × 800 mm and the 75 × 150 mm subway size among them. Counts are from the sixty product records, updated 5 October 2026.
Every tile in this range states at least one dimension, and for most of them it is the size of the face you would see. This page sets those dimensions side by side — five field-tile formats and nine mosaic sheet sizes — and works out what each one does to one square metre of finished surface. Scale is the part of a tile that can be calculated from what is on file rather than judged from a picture; every count on this page was read from the collection and product pages, most recently on 5 October 2026.
Standard tile sizes in Australia, as nine guides list them
On 29 September 2026 we read the Australian tile size guides that Google showed in its top twenty for tile sizes australia and standard tile sizes: nine articles from tile retailers, tilers and a design platform, each listing sizes in millimetres. Shop-by-size pages, calculators and overseas sites were left out. The table counts how many of the nine list each size, for every size that four or more of them list. Two of the nine carry the same size chart, so the counts for sizes on that chart are one higher than nine independent lists would give.
| Size | Guides that list it (of 9) | Made here |
|---|---|---|
| 600 × 600 mm | 9 | Yes — thirty-four tiles |
| 600 × 1200 mm | 8 | Yes — twelve |
| 300 × 600 mm | 7 | Yes — nineteen |
| 200 × 200 mm | 7 | No |
| 300 × 300 mm | 7 | No |
| 450 × 450 mm | 7 | No |
| 75 × 150 mm | 6 | No |
| 75 × 300 mm | 5 | Yes — nine |
| 100 × 300 mm | 5 | Yes — two |
| 100 × 100 mm | 5 | No |
| 400 × 400 mm | 5 | No |
| 800 × 800 mm | 5 | No |
| 1200 × 2400 mm | 5 | No |
| 450 × 900 mm | 4 | No |
Ask which size is the most common and the guides do not agree. One names 300 × 600 mm as the most popular tile size in Australia, then gives 450 × 450 and 600 × 600 mm among the most popular floor sizes. Two others name 600 × 600 mm: one as the most popular floor tile size in Australia, the other as the standard size for main floors now. What all nine share is 600 × 600 mm; eight list 600 × 1200 mm and seven list 300 × 600 mm. Those three are also the three formats made most often here.
The sizes in a guide are nominal, the name a size is sold under. What a product page actually records — a face, a sheet or a piece, and a thickness — is worked through in How tile size is stated.
The sizes you will not find here
Nine of the fourteen sizes in the table are not made in this range: 75 × 150, 100 × 100, 200 × 200, 300 × 300, 400 × 400, 450 × 450, 450 × 900, 800 × 800 and 1200 × 2400 mm. Nor is 1200 × 1200 mm, which three guides list. If a plan depends on one of those sizes, no tile here matches it. The smallest field format here is 75 × 300 mm and the largest is 600 × 1200 mm; everything smaller than 75 × 300 mm comes as pieces on a mosaic sheet. The subway sizes are taken one by one in Subway tile sizes in Australia, and what counts as large format in Large format tiles: how large?
Scale is the part a photograph does not carry
What to confirm before choosing sets out what a photograph loses on the colour side. Scale goes the same way for a different reason: a product shot is one unit or one sheet, and nothing in the frame fixes how large that unit is. The repeat has to be reconstructed rather than looked at.
What makes that possible is that a dimension is recorded, and a dimension multiplies. Fifty-nine of the sixty product pages state a face or sheet size in millimetres. The rest of this page is what happens when you multiply one. Which row that figure sits in — a face, a sheet or a piece — is worked through in How tile size is stated.
Five field-tile formats and nine mosaic sheet sizes
Across the range the site states fourteen distinct face sizes. Five are field-tile formats: 75 × 300 mm, 100 × 300 mm, 300 × 600 mm, 600 × 600 mm and 600 × 1200 mm. The other nine are mosaic sheet sizes, and by area they all fall between 225 × 230 mm and 306 × 306 mm.
As at 5 October 2026, nineteen tiles are made at 300 × 600 mm, thirty-four at 600 × 600 mm, twelve at 600 × 1200 mm and nine at 75 × 300 mm. Each of those pages states its own count, and other collection pages already name two or three formats side by side. The thirty-four squares are compared row by row in 600 × 600 mm tiles: 34 compared. The nineteen rectangles are compared in 300 × 600 mm tiles: 19 compared.
What none of them does is turn a format into an area. The largest field format is thirty-two times the area of the smallest: 75 × 300 mm is 0.0225 m², 600 × 1200 mm is 0.72 m².
Two tiles are made at 100 × 300 mm — Studio Chalk and Studio Linen — and the site has no collection for that format. The subway tiles page gives the split, eleven in all: nine at 75 × 300 mm, two at 100 × 300 mm.
One square metre, counted in units
One unit multiplied until it fills a surface is a single division on paper. With no allowance made for joints, one square metre holds:
- 44.4 tiles at 75 × 300 mm;
- 33.3 at 100 × 300 mm;
- between 10.7 and 19.3 mosaic sheets;
- 5.6 tiles at 300 × 600 mm;
- 2.8 at 600 × 600 mm;
- 1.4 at 600 × 1200 mm.
These are gross figures, with no allowance for joints or cuts: a way of picturing a surface, not a quantity to order against — How to measure a tiling project covers that side. The 300 × 600 mm page takes the same count further, into what it means for the joints; this page stops at the units. How many tiles in a box, and how many per square metre? puts the same figures beside the box each size comes in.
What a tiled surface asks you to clean takes the same count further still, into the length of joint each format holds.
For a mosaic the thing that repeats is not the sheet. The white tiles page already runs its range from 12.8 × 95 mm fingers to 600 × 1200 mm formats; put those ends into one division and a single 600 × 1200 mm tile covers the gross area of 592 fingers. That is the narrowest piece stated here, though not the smallest by area — one sheet is made of 20 mm rounds.
Twenty-eight tiles are made in two formats, and none in three
Twenty-eight tiles belong to two of the four size collections: eighteen pair 300 × 600 mm with 600 × 600 mm, and ten pair 600 × 600 mm with 600 × 1200 mm. No tile pairs 300 × 600 mm with 600 × 1200 mm, and none of the nine at 75 × 300 mm is made in a second format.
Twenty-eight is de-duplicated, taken from the sixty product records rather than by adding eighteen and ten, because adding collection counts double-counts anything sitting in three of them. Nothing sits in three.
The 600 × 1200 mm collection now holds twelve tiles. Ten of them are also made as a 600 mm square; Pietra Vela and Pietra Vela Fluted are made at 600 × 1200 mm and nothing else, so the long format is no longer always a second size for a tile you can also have as a square.
Choosing one of the two sizes on the product page
Since 5 October 2026 the twenty-eight tiles made in two sizes let you choose the size with a button on the product page: eighteen offer 300 × 600 mm or 600 × 600 mm, and ten offer 600 × 600 mm or 600 × 1200 mm. The page opens on 600 × 600 mm, the order is placed for the size chosen, and eleven of the twenty-eight also offer a choice of finish.
The product description still lists both sizes on one line, for example Sizes: 300 × 600 mm; 600 × 600 mm. The table of details below it follows the button: its Size reference row shows the size selected, and its Box coverage row the box for that size.
The two boxes do not come from the same source. The 600 × 600 mm box is in the supplier's current documentation, 4 pieces, 1.44 m², 30 kg, on all twenty-eight. For the other size the documentation gives no box, so the page uses the typical pack for that size: 8 pieces of 300 × 600 mm, or 2 pieces of 600 × 1200 mm, 1.44 m² per box either way. The page says that the supplier's current documentation does not state it and to confirm before ordering. Because every one of these boxes covers 1.44 m², the box count for an area comes out the same at either size; the piece count does not.
The size collection and the large format collection are not the same list
As at 5 October 2026 large format tiles lists thirty-six and 600 × 1200 mm tiles lists twelve. Every one of the twelve long-format tiles is in both; the large format page also carries twenty-four more whose large format is the 600 mm square rather than the long rectangle. That page says its grouping follows recorded tile dimensions, so where the question is a dimension, take it from the size collection.
Floor and wall: what the collections here list, by size
Three of the nine guides above name a size for floors. The collections on this site are not split that way. There is no floor tiles collection here, and the only collection named for walls or floors is wall tiles. It lists twelve: the nine subway tiles at 75 × 300 mm, the two at 100 × 300 mm and one tile at 300 × 600 mm, Studio Pure White. The kitchen and bathroom collections run across every size, as the table counts (bathroom column updated 6 October 2026).
| Size | Made here | Wall tiles (12) | Kitchen splashback tiles (24) | Kitchen tiles (38) | Bathroom tiles (56) |
|---|---|---|---|---|---|
| 75 × 300 mm | 9 | 9 | 9 | 9 | 9 |
| 100 × 300 mm | 2 | 2 | 2 | 2 | 2 |
| 300 × 600 mm | 19 | 1 | 1 | 7 | 16 |
| 600 × 600 mm | 34 | 0 | 0 | 12 | 30 |
| 600 × 1200 mm | 12 | 0 | 0 | 8 | 11 |
| Mosaic sheets | 12 | 0 | 12 | 12 | 12 |
A tile made in two sizes is counted under both, so a column adds up to more than the number in its heading. A collection is how this site groups the range for browsing: being listed in one is not a finding that a tile suits that surface. Wall tiles vs floor tiles sets out what a product page here records on that question and what it leaves to the installer. Where an article here runs a floor through the arithmetic, as How many tiles do I need? does with a 600 × 1200 mm tile, it leaves the same question to the tiler and the supplier's documentation.
Eleven sheets state a sheet size; the twelfth states a piece size
As at 5 October 2026 mosaic tiles lists twelve. Eleven state a Sheet size, falling on nine distinct specifications — 316 × 277 mm and 296 × 299 mm each appear on two products.
The measuring guide already warns not to assume one design shares a sheet size with the next. The size of that variation is 1.81 to one: 225 × 230 mm on Carrara Fan Mosaic Tile up to 306 × 306 mm on Carrara Square Mosaic Tile. Other pages quote a narrower span for their own smaller sets, so read any such range with the set it was measured over.
Largest by area is not longest. The longest single edge among the eleven is 325 mm, on Carrara Hexagon Mosaic Tile at 282 × 325 mm, which ranks third by area. Wherever this page names a largest or a smallest sheet, it means by area.
The twelfth is Studio White Finger Mosaic Tile. Its Specifications panel states Piece size: 12.8 × 95 mm and a finish, and no sheet size; the size row reads Check current size rather than a measurement. It is the one product in the range whose overall dimensions are not on the page.
Nine mosaics state both a sheet size and a piece size
Ten products state a Piece size and eleven state a Sheet size. Nine state both, and all nine are mosaics. A sheet size tells you how large the thing in your hand is. A piece size tells you how large the unit that repeats across the surface is. On a field tile those are one number, which is why only mosaics carry two.
Where both are stated and the piece is given in two dimensions, gross sheet area divided by gross piece area runs from 17.2 to 56.9, median 34.9. That is six of the nine; the other three state a piece in one dimension only — 20 mm, 75 mm, 70 mm hexagon — so no area can be taken from them. It is a ratio of areas with joints ignored, not a piece count. How to measure a tiling project counts a mosaic from the area of one sheet, the unit a mosaic is sold in here. A sheet does not say how many pieces it holds, though, and no product page in the range states one.
Browsing by size reaches forty-six tiles; reading the page reaches fifty-nine
Forty-eight products carry a tag beginning Size:, and for three of the four size collections that tag and the collection match exactly, product for product. The fourth does not. Not one of the nine tiles at 75 × 300 mm carries a Size: tag; they carry the bare dimension, 75 × 300 mm, and that collection is built on it. A tile can be outside the size system in the product data and still be browsable by size.
It runs the other way too. Two tiles carry 100 × 300 mm the same bare way and there is no collection for that format, and eleven mosaics carry a Size: tag while sitting in no size collection at all. Forty-six products sit in at least one size collection; fourteen sit in none — the twelve mosaics, plus the two at 100 × 300 mm. Browsing by size reaches forty-six of them, reading the product page reaches fifty-nine, and one product is in neither set: Studio White Finger Mosaic Tile carries no dimension tag and states no overall size.
Before you judge a tile on scale
Scale is settled on the product page, in this order:
- the face size — not one more row to check, but the unit that will repeat across the whole surface;
- for a mosaic, whether the page states a sheet size, a piece size or both — and which the size row is showing, since four mosaic pages put both numbers there and Carrara Petite Herringbone leads with the piece;
- whether the tile is made in a second format, since twenty-eight here are and the second format changes the count per square metre outright, and which of the two the page has selected;
- whether the format you want can be browsed at all, since two tiles at 100 × 300 mm sit in no size collection;
- the one size row that reads
Check current size, where the sheet dimension is not on file.
Every dimension on this page was read off a product page, and every count off a collection or product page, most recently on 5 October 2026. The list of common sizes comes from nine Australian tile size guides read on 29 September 2026; they are counted, not named. A measurement is not a recommendation: no arithmetic here says whether a format suits a particular surface, or settles a layout. Check the size stated for the tile you have chosen, and confirm project requirements with the responsible installer or specifier before ordering.
Questions people ask
What is the most common tile size in Australia?
There is no single answer. Of nine Australian size guides read on 29 September 2026, all nine list 600 × 600 mm, eight list 600 × 1200 mm and seven list 300 × 600 mm. Where a guide names a most popular size, the answers differ: one names 300 × 600 mm for Australia as a whole and gives 450 × 450 and 600 × 600 mm for floors, and two others name 600 × 600 mm. In this range 600 × 600 mm is the format made most often, with thirty-four tiles.
What tile sizes are there in mm?
The guides run from mosaic pieces under 25 mm square (19 × 19 mm is the smallest listed) up to slabs 3000 mm long. This range has five field-tile formats — 75 × 300, 100 × 300, 300 × 600, 600 × 600 and 600 × 1200 mm — and twelve mosaics, eleven of which state a sheet size between 225 × 230 mm and 306 × 306 mm by area.
What is the largest tile size here?
600 × 1200 mm, made by twelve tiles: eight Pietra, two Atlas and two Coastal. Ten of them are also made as a 600 × 600 mm square, with the size chosen on the product page; Pietra Vela and Pietra Vela Fluted are made at 600 × 1200 mm only. The guides list larger sizes, 1200 × 2400 mm in five of the nine and slabs up to 3000 mm long; none of those is made here.
Can I choose between two sizes on the product page?
Yes, on the twenty-eight tiles made in two sizes, since 5 October 2026. The table of details on the page then shows the size and the box for the one selected. For 300 × 600 mm and 600 × 1200 mm that box is the typical pack for the size, which the supplier's current documentation does not state, so confirm it before ordering.
Is there a standard tile size?
Not one that every tile follows. The guides list common sizes, and each is a nominal size; the dimension that counts is the one stated on the product page for the tile you choose.
Scale also sets the unit you will count in. A field tile is counted in pieces and a mosaic in sheets; the per-square-metre figures above are those units with no allowance for joints, and an order is placed in boxes for a field tile, whose coverage is a separate row on the product page, and in sheets for a mosaic. To turn a stated size into a count for your own surface, the tile calculator takes the net area in metres and one tile or sheet size in millimetres and rounds up to whole pieces. It does not return boxes.
Next step — read what the rest of the panel records. What to confirm before choosing works through the other rows in the same Specifications panel, and what each one leaves blank.
