Your 2023 Guide of Tile Thickness

When it comes to tile, thickness is an important factor to consider. The thickness of your tile can impact everything from the look of your finished project to the durability and longevity of your tile.

However,this can be a confusing topic for many people, so we've put together a guide to help you understand everything you need to know about tile thickness.


Standard thickness of tile

•The standard thickness of tile range from 1/4 to 3/8 inch.

•The thickness of a tile depends on the material from which it is made and the manufacturing process.

•The thickness of the tile most usually depends on the material. Some tile materials can be thicker or thinner than standard materials. For example, mosaic tiles tend to be thinner, while natural stone can be thicker.

•To make sure your floor is installed correctly, you need to take into account the type of installation and thicknesses involved. For example, the thickness of tile used in a bathroom is different from that found in kitchens and other areas. This has to do with where the room will be installed, as well as what type or design you're going for.


Thickness of wall tile

1/4 inch to 3/8 inch is the typical wall tile thickness. However, decorative wall tiles can be thinner, such as 1/8 inch.Wall tiles, like floor tiles, come in a variety of shapes and size options. You can turn to specialized shapes or oversized wall tiles to achieve your design goals. However, wall tiles are always thinner than floor tiles. This is because floor tiles need to withstand frequent traffic flow, the weight of furniture and the impact of falling objects, etc. Thinner wall tiles are also easier to install. Wall tiles are not suitable for use on floors because they are not designed for that purpose.

Thickness of floor tile

Most floor tiles are approximately 1/2 inch to 3/4 inch thick. Square tiles and rectangular tiles are the most common choices for floor tiles. Octagonal, hexagonal, trapezoidal, etc. are also available if you are looking for a distinctive visual effect. In general, larger floor tiles will be thicker than smaller floor tiles. Some floor tiles will fall outside of this range, such as smaller decorative floor tiles that are only 1/8 inch thick.

Thickness of ceramic tile

One of the most important factors to consider when installing ceramic tiles in your home is their durability. They can be used for all sorts and styles, from bathrooms or kitchens as well as laundry rooms! This versatile product comes with different thicknesses ranging anywhere between 1/4 inch up 3/4 inch. The thicker they are generally means that there are less likely to break.


Thickness of porcelain tile

Porcelain tiles are more similar to ceramic than they're different. Though it's highly tolerant of stains, scratches and moisture which makes them a good choice for residential or commercial flooring - particularly high traffic areas where wear-and tear is expected the most often from foot traffic on your floors! There’s also an array colors available with porcelains including smooth textures in 5/16 inch thicknesses along raised patterns that can be found at various depths below ground level depending upon what look you prefer (or need).


Thickness of thin-body tile

Thin-body tiles offer a more eco-friendly alternative to heavy weight options because they use less material and take less energy production.They can be manufactured in 3–6 millimeter thicknesses.

However this also means you need special care when installing; installers often have specific equipment in order for the job go smoothly (especially if it concerns those on thinner ends).

Importance of correct tile thickness

Thicker tiles offer stronger hardness ratings and greater durability. But choosing the correct tile thickness is one of the key details. For example, on walls, the only way to install an electrical box at a correct depth is to have its wall plate flush with the finished wall tile. And with floor tiles, the last thing you want is for your floor tiles to be higher or lower than those in adjacent areas, or for your doors to not be able to swing freely through the space. Also, if you have a kitchen with floor tile and a dining area with vinyl tile, you need to use a thicker underlayment underneath the vinyl tile in order to achieve an aesthetically pleasing excess.


Is the thicker the tile, the better?

The thickness of a tile determines its strength. The thicker the tile, the higher the hardness level and the more pressure it will withstand. Usually there are 5 levels of hardness rating as follows.

Class I - No foot traffic; this type is only meant for walls.

Classes II – Light traffic and can be used inside residential or commercial settings where there's little abrasion on walls like bathrooms.

Class III - Light to moderate traffic. This type are perfect for normal foot traffic areas like homes and office buildings. They're also great choices for countertops or walls.

Class IV - Moderate to heavy traffic. This class is for those who live in areas with high traffic. It's ideal to use this on your home, medium commercial or light institutional building floors.

Class V - This type of tiles are approved for all residential applications including heavy commercial work. These durable materials can stand up against foot traffic in institutions like hospitals or schools without showing any signs that they’ve been damaged.


Please don't go for a higher hardness rating and choose a thicker tile. The right thickness of tile helps you avoid expensive mistakes and redo your project as you go along.


Allowing for thinset

Thin cement, slurry mortar, dry mortar and dry combined mortar are synonymous to each other. This type of cement adheres very well to thin layers. Tile thickness is different from the thin layers.

Usually, a thin layer 3/16 inch to 1/8 inch thick under the tile. For smooth tiles on the back, 3/16 inches are thin enough to attach the tile to the floor or pad. For natural tiles with uneven back, you may need to lay a 1/8 inch thin layer during installation. The thinset works best when it is a relatively thin layer of material scattered over a smooth surface or backplane.
