Short answer: A tile size is one of three different things, and the row name tells you which. A face size is the tile you would see. A sheet size is the mesh a mosaic arrives on. A piece size is one chip inside that mesh. Fifty-nine of the sixty products here state a face or sheet size in millimetres — and not one of them says whether that figure is the nominal size or the actual one.
Search how a tile size is arrived at from an Australian address and you get two different conversations stacked on top of each other. Google's summary answers the question about the tile: length and width of the face, and it goes on to note that the figure on a box is often a rounded, nominal one. Four of the seven results below it answer a different question — how to work out how many square metres a room needs. Both are useful. This page does only the first, because the second already has pages of its own, and because the first is the one no Australian site on that results page is currently covering.
1. Three rows, three different objects
Across the sixty product records here, size appears under four different row names.
| Row | Products | What the number describes |
|---|---|---|
| Size | 20 | The face of the tile, where the tile comes in one format |
| Sizes | 28 | The face, where the same tile is made in two formats, separated by a semicolon |
| Sheet size | 11 | The mesh sheet a mosaic arrives on, not any tile on it |
| Piece size | 10 | One chip within the sheet |
Forty-eight products carry a Size or Sizes row and eleven carry a Sheet size row, which is the fifty-nine. The one that carries neither is Studio White Finger, whose record gives a piece size of 12.8 × 95 mm and asks you to check the current sheet size. That is unusual enough to be worth naming rather than averaging away. Its sheet is sold, but the sheet's overall size is not recorded.
The Sizes row has one addition, updated 5 October 2026. On the twenty-eight products that carry it, the description still gives both formats on one line, separated by a semicolon, and that line has not changed. What is new is the page around it: the size is now chosen with a button, and the table of details below the description shows the selected size in its Size reference row and the box for that size in its Box coverage row. So the row name Sizes still means one tile made in two formats, and the table tells you which of the two you are about to order.
The distinction between the first two rows and the last two is the one that costs people money. A mosaic listed at 306 × 306 mm is not a 306 mm tile; it is a sheet of smaller pieces. If you priced a splashback by treating that figure as a tile face, the count would come out wrong: on the six sheets here whose pieces are given in two dimensions, a sheet's area is 17 to 57 times its piece's. Tile sizes in Australia carries that through to what each format does to a square metre.
2. The trap in the tag
There is a second place a size appears, and it uses a different word for the same number. Eleven of the twelve mosaic products carry a style tag reading Size, followed by the sheet dimensions — so Carrara Hexagon is tagged Size: 282 × 325 mm while its specification row calls the same figure Sheet size.
Forty-eight products carry a Size tag of some kind. It is not wrong, but it is looser than the row underneath it, and a browsing filter built on tags will put a 282 mm sheet next to a 300 mm tile face as though they were comparable. The rule that follows from this is short: read the row name, not the tag. Two white tiles that look the same makes the same point about the size row being the one everyone reads and the one that hides a sheet.
3. Which number comes first
On a field tile the convention here is short side then long: 75 × 300 mm, 300 × 600 mm, 600 × 1200 mm. Nothing states that convention on the page; it is simply what all forty-eight do.
On mosaics the order is less predictable, because there are two numbers to place. Of the four mosaic tags that carry both numbers, three put the sheet first and the chip second. Carrara Petite Herringbone runs the other way: its tag reads 30 × 60 mm / 270 × 262 mm, with the chip in front. Anyone writing a script to parse the first number out of that field will get the chip on one product and the sheet on the next.
Which is the practical version of the rule above. The position of a number tells you nothing reliable. The row name does.
4. Two sheets that do not say how big the chips are
Nine of the twelve mosaics here state both a sheet size and a piece size. Two, below, state a sheet size but no piece size; the twelfth, Studio White Finger, states a piece size but no sheet size.
| Product | Sheet size | Piece size |
|---|---|---|
| Carrara Hexagon Mosaic Tile | 282 × 325 mm | Not recorded |
| Carrara Square Mosaic Tile | 306 × 306 mm | Not recorded |
On both of those pages you can see how big the sheet is and not how big the individual hexagons or squares are. No figure on this site fills that in, and putting a plausible one there would be inventing it: a 282 × 325 mm sheet could hold chips of several different sizes. The honest routes are to order a sample, which is a piece of the actual sheet, or to ask before ordering. All twelve mosaics, with both sizes and the material each records, are in one table in Mosaic tiles: the sizes and materials of the twelve here.
Where a chip size is given it can be specific in a way that is worth noticing. Carrara Large Hexagon states 70 mm hexagon. Carrara Round states 20 mm. Carrara Fan states 75 mm. Each of those is a single number for a shape that has more than one dimension, which brings us to the next point.
5. What a single number leaves open
A rectangle needs two numbers and gets them. A hexagon or a round chip gets one, and one number does not fully describe a hexagon: the distance across the flats and the distance across the points differ by about fifteen per cent. The record does not say which of those 70 mm refers to.
That is not a complaint about the supplier's documentation — it is the sort of thing that only matters when you are setting out a run and need to know where the joints land. It is recorded here so that you know to ask rather than assume.
6. Nominal and actual, which no page here settles
Google's summary makes a point that is worth repeating: the size stated for a tile is often a nominal figure, rounded from the actual one. It is an established distinction in the trade, and on the first page of Australian results for this search, no Australian site leads with it. The two whose summaries take it up are a manufacturer in India and a retailer in the United States; we did not open the full text of the other results.
This site cannot settle it either, and the reason is specific. Searching all sixty product records for nominal, actual size, tolerance and calliper returns nothing. Not one page here uses either word. So what a size row gives you is the figure in the supplier's current documentation, and the page does not say whether that figure is nominal or actual — and nobody here has put a rule across a tile to find out.
Which has one practical consequence. If your layout depends on a run coming out exactly — a splashback between two cabinets, a niche sized to whole tiles — the figure on the page is the right thing to plan with and the wrong thing to commit to. A sample is a piece of the real product, so measure that before you commit to the run.
7. The third dimension, and where it is blank
Thickness is the one size that is not about the face, and it is recorded on fifty-nine of the sixty. There are four values in the whole range: 10 mm on thirty-seven tiles, 8 mm on sixteen, 6 mm on four and 7 mm on two. The one that reads Not specified is Studio White Finger, the same mosaic that gives no sheet size. The other eleven mosaics now state one: 6 mm on the four ceramic sheets, 7 mm on the two porcelain strips and 8 mm on the five marble sheets.
Units are consistent throughout: every size figure on this site is in millimetres. The American and Indian results on that same search page work in inches and square feet, which is worth knowing if you are comparing across them.
How many types of tile sizes are there?
Counting distinct face dimensions across this range gives fourteen, of which five are field tile formats and nine are mosaic sheet sizes. That count and the arithmetic behind it are in tile sizes in Australia.
What is the size of a 200x200mm tile?
Nominally, a face 200 mm on each side. Whether the piece in the box is exactly that is not something a listing states, here or elsewhere. This site does not stock a 200 × 200 mm tile; the closest squares here are 600 × 600 mm, and the smallest square faces are mosaic chips.
What sizes do tiles come in?
On this site: five field formats from 75 × 300 mm to 600 × 1200 mm, plus nine mosaic sheet sizes between roughly 225 × 230 mm and 306 × 306 mm, with pieces from 20 mm rounds and 12.8 mm-wide fingers to 36 × 150 mm bars. The full set with pieces per square metre is in the scale guide.
8. Where these facts come from
Row names, counts, sheet and piece sizes, thickness values and the two sheets with no chip size come from the sixty product records on this site, read on 18 September 2026. Thickness values were updated on 1 October 2026 from supplier documentation, which added a thickness to nineteen products. The nil result for nominal, actual, tolerance and calliper came from searching those same sixty records for those terms. The count of fourteen distinct face dimensions is the figure already published in the scale guide. The observation that no Australian site on the first page covers nominal against actual is from the Australian results for this search on the same date — seven results, five of them Australian — and from the summary Google printed above them. No tile in this range has been checked against its stated size by anyone here; a size row is the supplier's figure, and what to confirm before choosing lists the other rows in the same position. The size choice on the twenty-eight two-size pages was checked against the product records on 5 October 2026. If what you actually need is the quantity for a room, that is how to work out a tiling project and the calculator.
