Short answer: large format has more than one starting point. An ARDEX technical bulletin uses a side at least 400 mm long; Google's Australian search summary starts at 600 × 600 mm. Tilekind's collection is organised around 600 × 600 and 600 × 1200 mm formats. It contains thirty-six products, and 1200 mm is the longest recorded side in this range.
Those descriptions serve different purposes. One introduces technical considerations, another summarises search results, and the third organises a shop. Reading them together is useful, provided a definition, a size option and a product count stay separate.
1. Start with what the name is doing
The word large does not give a complete dimension. It can lead you to a category, but the product record still has to supply the face size. A square and a rectangle can share the category without sharing a shape, and a product can belong to it while also offering a smaller format.
| Source | Starting point or grouping | What it describes |
|---|---|---|
| ARDEX Australia, TB001.010 | At least one side 400 mm long | A technical bulletin's large-format definition |
| Google's Australian AI summary | Typically starts at 600 × 600 mm | A broad search summary, extending to much larger slabs |
| Tilekind large-format collection | 600 × 600 and 600 × 1200 mm formats | The recorded dimensions used to organise this collection |
The ARDEX bulletin gives 400 × 400 mm as a typical example, but its definition is not restricted to squares. A 300 × 600 mm rectangle also has a side long enough to meet it. The document is an installation-materials manufacturer's technical bulletin, not the rule that controls every retailer's category name.
Google's summary describes formats extending beyond 1200 × 2400 mm. That is a description of a wider market. It does not mean a shop using large format in its navigation carries slabs of that size.
2. The collection is the list
The large-format collection gives its own boundary: recorded 600 × 600 and 600 × 1200 mm formats. Its description also separates this grouping from claims about material or intended application. There is no reason to read a material specification or a room-use decision into the category name.
Thirty-four products have a 600 × 600 mm option. Twelve have a 600 × 1200 mm option, and ten belong to both groups. Adding the two size counts would count those ten products twice.
The collection total is therefore thirty-six: the thirty-four square-format products, plus the two products offered only in the long format. Those two are Pietra Vela Marble-Look Tile and Pietra Vela Fluted Marble-Look Tile.
| Recorded size group | Products | How to read the count |
|---|---|---|
| 600 × 600 mm | 34 | Includes products that also record another format |
| 600 × 1200 mm | 12 | Ten also record the square format |
| Both of these formats | 10 | Overlap, not additional products |
| Long format only | 2 | The two Vela products |
| Distinct products across the groups | 36 | The collection membership |
The square-size collection and long-size collection are more precise starting points when you already know the dimension you are comparing. Keep the chosen format in your notes: the product name alone may leave two size options open. 600 × 600 mm tiles: 34 compared compares the thirty-four made as the square. The twelve made in the long format are set side by side in 600 × 1200 mm tiles: 12 compared.
3. Applying the technical definition changes one product
There are forty-eight field-tile products here, separate from the twelve mosaic products. Applying the ARDEX side-length definition to the recorded field-tile dimensions includes thirty-seven. The shop's large-format collection includes thirty-six.
The difference is one product: Studio Pure White Wall Tile. It records only 300 × 600 mm. Its longer side meets the technical definition, but it does not offer either of the formats around which this collection is organised.
| Comparison across the 48 field-tile products | Count |
|---|---|
| Meet the ARDEX side-length definition | 37 |
| Belong to the Tilekind large-format collection | 36 |
| Meet that definition but are outside the collection | 1 |
| Belong to the collection but do not meet that definition | 0 |
| Do not meet that definition | 11 |
All eleven excluded field tiles are subway products. Their recorded faces are 75 × 300 or 100 × 300 mm; the longest side is 300 mm, below the bulletin's 400 mm threshold.
A smaller size option is not the same thing as a product outside the collection. Many products offer both a smaller rectangle and a square. Their square format brings them into the collection; their other size does not remove them. That distinction keeps the two definitions from appearing further apart than they are.
This comparison uses field tiles only. It does not treat the outside dimensions of a mosaic sheet as the face dimensions of one field tile, or use a sheet to alter the technical-definition count.
4. Where this range stops
The largest recorded field format here is 600 × 1200 mm. There are no recorded 750 × 750, 800 × 800, 900 × 900, 1000 × 1000 or 1200 × 1200 mm square formats. There is no 1200 × 2400 mm slab, and no 200 × 1200 mm plank in this range.
That is a boundary of the catalogue, not a boundary of the Australian market. A large-format search can show all those kinds of dimensions without establishing that they are options within this collection.
Eleven product pages also carry the words Large format in the Style / shape row: the three Atlas products and eight long-format Pietra products. The collection is the complete list; the words in that row appear on a smaller set of pages. They are not a substitute for checking membership or reading the size.
Tile sizes in Australia covers the wider relationship between field formats and mosaic sheets. This reading uses current collection membership: all twelve long-format products are in the large-format collection. Older statements about the two lists differing do not describe the membership used here.
5. A size group still contains different records
The collection brings together fourteen marble-look products, six concrete-look, six stone-look, five travertine-look and five terrazzo-look products. Those are look categories. The recorded material is Porcelain on all thirty-six, the fourteen Pietra marble-look products included.
The stone-look collection and marble-look collection provide routes through appearance. The large-format collection provides a route through dimensions. The material and finish vocabulary guide explains why those descriptions cannot stand in for one another.
All thirty-six products in this collection record 10 mm thickness. For eight of them (Quarry Sand, Quarry Ash and Quarry Stone; Atlas Ivory and Atlas Frost; Pietra Perla, Pietra Vela and Pietra Vela Fluted) the value was updated on 1 October 2026 from supplier documentation.
A slip class is recorded for all thirty-six products, including entries carried in tags rather than a separate description line. Neither the category name nor a listed size settles the project requirements left open by those records.
Weight is recorded only per box. Since 2 October 2026, from supplier documentation, all thirty-six pages state 30 kg for one box: four 600 × 600 mm pieces, or two 600 × 1200 mm pieces on Pietra Vela and Pietra Vela Fluted. On the tiles made in two sizes no weight is stated for the box of the other size, and no product page here records weight in kg/m² or weight per tile. The ARDEX bulletin defines heavy stone or ceramic tiles as exceeding 32 kg/m², and also mentions an often-used adhesive-fixing guide of 4 kg per tile. These are different quantities, not two interchangeable limits.
A box weight is not the per-square-metre or per-tile weight those figures use, so this guide does not use it to classify a tile here as heavy or to say how it can be handled or fixed. A thickness value cannot fill that gap either. The bulletin's examples are not instructions for a particular product in this collection.
6. Questions about the name and the range
What are the standard sizes of large tiles in Australia?
The sources here do not establish one retail starting point. ARDEX describes a side-length threshold, Google's summary starts with a square format, and this collection states its own two-format grouping. The exact dimensions on the product page are more useful than treating any one category label as a universal size standard.
What sizes do large format tiles come in?
In this collection, the recorded choices are 600 × 600 and 600 × 1200 mm. Some products offer both. Wider Australian search results show other squares, rectangles and slabs, but those examples do not extend the dimensions available in this catalogue.
What are the biggest size tiles available?
Here, the longest recorded side is 1200 mm, on a 600 × 1200 mm format. Google's summary discusses larger slabs elsewhere. This guide does not establish the largest tile available across Australia, and the market example is not a product offering by Tilekind.
7. Where these facts come from
Product dimensions, collection descriptions, membership and the Australian Google summary were read on 18 September 2026; the material, thickness and slip counts in section 5 were updated on 1 October 2026 from supplier documentation, and the weight sentences in section 5 on 2 October 2026. The technical source is ARDEX Australia, TB001.010, dated 9 July 2024: https://ardexaustralia.com/pdf/tech%20bulletins/TB001.010_Fixing%20Large%20Format%20Tiles.pdf. Its definitions are reported in their technical context; no product weight is supplied by that document for this range.
Before taking a size comparison into a project decision, read what to confirm before choosing. The dimensions can be known while other essential fields remain open.
