Tiles are a long-term investment. We see tiles almost everywhere in homes, shopping malls, offices, and parking lots; they are on the floors we walk on and the walls we touch. However, nobody would want their tiles to fade and chip as time passes. Replacing them again within a short period involves more money and time. Such problems can be prevented by using the tile specifications that are just right for your space.
To be a smart tile buyer, knowing tile specifications is crucial. A basic knowledge of the materials, finishes, colors, size, thickness, slip resistance, water absorption, and suitability of the tiles for a particular space is all you need. This tile specification guide is about the important things to consider before buying tiles.
When it comes to tile specification, size becomes a major factor. Size influences what material works for that space, what finish holds up, how thick the tile needs to be, how much water it can handle, and whether the tile is suitable for the space. You can now find tile-size specifications from small mosaic pieces to large-format slabs of 1200x2400 mm. This larger choice of tile sizes offers you the flexibility to add tiles to different layouts and to serve different purposes.
Size | Format | Common Use | Why It Works |
|---|---|---|---|
| 100x100 mm / 150x150 mm | Small | Kitchen walls, cafes, bathrooms | Gives a retro or handmade feel. Works well as an accent or feature wall. |
| 300x300 mm / 300x600 mm | Medium | Bathrooms, utility areas, and kitchen walls | Easy to lay around fixtures and fittings. Good for spaces with lots of cuts. |
| 600x600 mm | Standard | Living rooms, bedrooms, and general flooring | A simple, practical choice that suits most residential floors without much fuss. |
| 800x800 mm | Large | Large living areas, commercial spaces | Makes a room feel more open. Fewer joints mean a cleaner finish. |
| 1200x600 mm and above | Slab | Open-plan floors, feature walls | Minimal joint lines give a seamless, premium look but need a very flat base and skilled installation. |
The material of a tile defines how durable, water-absorbent, maintenance-friendly, and expensive the tile is. The types of tile materials show how durable, safe, and appropriate the tile is for the space. Let us discuss some of the common ones.
The tile finish type is not just about looks. It changes how the tile feels underfoot, how often you need to clean it, and whether it actually suits the space you are tiling.
PEI stands for Porcelain Enamel Institute, an industry body that developed the standard test for tile surface wear. The rating tells you how much foot traffic a tile's surface can handle before showing wear. It ranges from 0 to 5. The tile PEI rating tells us how suitable it is to use in a particular room.
PEI 0 — Wall use only.
PEI 1 — Very light use, like a bathroom with bare feet only.
PEI 2 — Light residential. Bedrooms and bathrooms with soft footwear.
PEI 3 — Most residential floors. Living rooms, kitchens, hallways.
PEI 4 — Heavy residential and light commercial. Offices, retail.
PEI 5 — High-traffic commercial. Malls, airports, hospitals.
Quick Tip: For most homes, PEI 3 is good to go. Entrances and home offices with heavy use are worth upgrading to PEI 4.
The R rating measures the tile slip resistance. This shows how much grip the tile can provide, especially in spaces exposed to water such as bathrooms, terraces, and parking areas. It ranges from R9 to R13. The R rating and finish work together. A matt anti-skid tile will generally score higher than a glossy tile when it comes to slip resistance.
R9 — Dry indoor areas. Entrance halls, living rooms.
R10 — Light wet areas. Domestic bathrooms, kitchens.
R11 — Moderate wet or outdoor use. Balconies, commercial kitchens.
R12 — Heavy wet exposure. Pool surrounds and industrial kitchens.
R13 — Extreme conditions. Heavily wet industrial floors.
As we have discussed wear resistance and grip in the above section, let us know more about scratch resistance. The Mohs scale measures how resistant a tile's surface is to scratching. This ranges from 1 (very soft) to 10 (high scratch resistance). For floor tiles, anything above 5 is generally good.
A low tile Mohs rating does not mean the tile is bad. It means you need to be more careful about grit, furniture, and daily wear on that surface.
When tiles come out of the kiln, the firing process can cause very slight changes in size and shape. Not every tile comes out exactly the same, and that is the reason rectified and non-rectified tiles exist as two separate categories. The difference between the two is not just about appearance. It decides how the tiles are installed, how wide the grout joints need to be, and how the finished surface looks across a large area.
Non-rectified tiles are left as they come out of the kiln, with natural edges and slight size variation between pieces. Rectified tiles go through an extra cutting process after firing, so every tile comes out to exact dimensions with clean, precise edges. The type you choose determines how thin or wide the grout joints will be and how seamless the finish looks.
Specification Point | Rectified Tiles | Non-Rectified Tiles |
|---|---|---|
Edge finish | Edges are mechanically cut after firing for a sharper and more uniform size. | Edges are natural after firing, so slight size variation can be present. |
Joint width | It can be installed with very narrow grout joints. | Needs wider grout joints to manage small size differences. |
Installation | Needs skilled installation because narrow joints leave less room for adjustment. | Easier to install because wider joints allow more flexibility. |
Best use | Living rooms, bedrooms, premium floors, large-format tiles, and modern interiors. | Walls, regular floors, budget-friendly projects, and spaces where visible grout lines are acceptable. |
Every tile box detail carries a shade code, product name, size, batch number, finish, and box coverage. Easy to overlook, but ignoring it is one of the most common reasons installations end up looking patchy.
Tiles are made in batches. The same design from the same brand can look slightly different across two production runs. The shade code tells you which batch a box belongs to, and tiles from different codes may not match. Check that every box in your order has no tile shade variation before work starts. Verify that the product name, size, batch number, lot number, shade code, finish, and box coverage all match.
Before You Open The First Box, Check For:
Not every tile works in every space. A tile that looks great on a wall may crack under foot traffic. One that works perfectly outdoors may be too rough for a bedroom floor. Knowing where each tile specification belongs saves you from costly mistakes after installation.
Area | Tile Specifications |
|---|---|
| Walls | Lighter and thinner tiles work best here. Ceramic and porcelain are common choices. Glossy finishes are fine on walls since there is no slip risk or heavy wear to worry about. |
| Floors | Floor tiles need adequate thickness, a tile PEI rating of at least 3, and a finish that handles foot traffic. |
| Outdoor Areas | The best choice is porcelain with a low water absorption and an anti-skid finish. The tile should be able to withstand rain, heat, and temperature changes without cracking. |
| Wet Areas | Water-resistant tiles and slip resistance are non-negotiable when it comes to areas that face water every day. For bathroom tile specifications, R-10 is the minimum. Balconies and pool surrounds need R11 or above. |
Tile specifications are not there to confuse you. They help you pick the right tile for the right space. A tile that looks perfect in the showroom but carries the wrong PEI rating or no slip resistance will let you down fast in real conditions.
Check the shade code, the rating, the finish, and the suitability before you buy. It is far easier to swap a tile before purchase than to relay an entire floor after installation. Browse our full tile range, where every product lists its specifications clearly, so you can compare, confirm, and buy with confidence.
