TL;DR
- The Short explains why carpet tile dimensions differ across markets.
- Manufacturers offer formats; project teams select from available products.
- UNIJOY catalogue examples include 500 × 500, 500 × 1000, 333.3 × 1000 and 250 × 1000 mm.
- Compare modules on a plan and ask for the exact product sample.
Direct answer
Who decides which carpet tile size a project should use?
Manufacturers define the formats available for a product, while the architect, designer, specifier and installer decide which available module fits the project layout. Regional conventions influence what feels familiar, but the final choice should be checked against room dimensions, pattern scale, installation direction, perimeter cuts and the exact product record—not a universal size rule.
What the carpet tile size video explains
The short begins with the familiar 50×50 cm square and asks why other markets and projects use different numbers. Its visual timeline connects common formats with metric or imperial conventions, imported specifications, local supply and later demand for longer modular shapes.
The closing point is practical: a number is not the design brief. Size becomes useful only when it is connected to the room geometry, product identity, pattern and installation plan.

The size decision has two owners
The manufacturer controls which modules are offered for a named product. The project team controls which of those available modules enters the finish schedule and layout drawing. A designer may favour a square, plank or narrower strip for visual rhythm, but procurement and installation still need the exact product code and current format confirmed.
Do not convert a regional convention into a product promise. The current UNIJOY catalogue is the source for available published formats; the approved plan, sample and project documents control the intended use.
Choose by layout, not by the number alone
Start with a dimensioned floor plan. Mark the main sightlines, thresholds, fixed furniture, columns, perimeter cuts and any change of direction. Then place the candidate module on the drawing and review how the pattern repeats across the real space.
A sample review should record the exact series, code, colourway and module. Size alone does not establish wear, acoustics, dimensional stability, fire, emissions, installation compatibility or project suitability; those questions need their own current documents.

Current UNIJOY format examples
These live UNIJOY records give the project team named examples of square and plank formats to compare.
Size fields to record before selection
Record these fields beside the product and layout drawing when selecting the module.
| Field | Product or project detail | Note |
|---|---|---|
| Product identity | Record collection, design, product code and colourway. | A format without a named product is not a complete selection. |
| Published module | Copy the exact length × width from the current product page. | Do not substitute a visually similar regional size. |
| Room geometry | Use measured dimensions, thresholds, columns and fixed elements. | The module should be reviewed on the actual plan. |
| Layout direction | Record orientation, start lines, transitions and changes of direction. | Use the current product and installation information. |
| Pattern and sample | Review the physical sample and pattern scale in the proposed module. | A screen image cannot approve colour or installed appearance. |
| Approval record | Keep the chosen product, module, drawing revision and open questions together. | — |

Four current UNIJOY module examples
Use the formats to test how the room geometry and design rhythm change.
| Published format | Current UNIJOY example | Project question |
|---|---|---|
| 500 × 500 mm | UNIJOY Ancient 55905 | How does the square grid meet walls, doors and the intended pattern direction? |
| 500 × 1000 mm | UNIJOY Haze Wandering Garden 5187 | How will the long module run through the room and transitions? |
| 333.3 × 1000 mm | UNIJOY DunHuang 31X1 | Does the narrower plank support the drawing’s rhythm and perimeter cuts? |
| 250 × 1000 mm | UNIJOY Surge 21902 | How will the strip module repeat around fixed elements and changes of direction? |
Carpet tile module selection flow
Use the size question in a product enquiry
Designers can send the room plan and preferred visual direction with two or three named format options. Specifiers can record the exact module in the finish schedule. Procurement can keep the same product identity and drawing revision in the sample and quotation request.
For the next step, share the room dimensions, chosen UNIJOY product codes and layout intent. Ask for the current product information and sample for those exact records; confirm installation and commercial details in the live enquiry.
Carpet tile size FAQ
Who decides carpet tile sizes?
Manufacturers decide which formats are available for each product. The project architect, designer, specifier and installer select an available format against the room and layout.
Is 500 × 500 mm the only standard carpet tile size?
No. It is a familiar square format, while the current UNIJOY catalogue also lists 500 × 1000, 333.3 × 1000 and 250 × 1000 mm modules.
Does a larger or smaller carpet tile perform better?
Size alone does not determine technical performance or project suitability. Compare the exact product construction, documents, installation requirements and layout.
Which UNIJOY products show different formats?
Current examples include UNIJOY Ancient 55905, Haze Wandering Garden 5187, DunHuang 31X1 and Surge 21902. Open each live record for its published fields.
How should I request a size-specific sample or quotation?
Send the exact product code, colourway, module, room plan and intended layout through the contact page, then confirm current availability and terms in that enquiry.
