A smooth, even tiled surface starts with proper preparation and correct installation. However, small height differences can still occur between adjacent tiles during installation. These are particularly noticeable with large-format and rectified tiles.
A tile levelling system helps reduce these height differences during installation. But how exactly does a tile levelling system work, and why do more and more tilers use one? We explain the main benefits below.

A tile levelling system is a tool used during tile installation to keep the edges of adjacent tiles at the same height while the tile adhesive cures.
Depending on the system, you can work with clips and wedges or clips and screw caps. The clips are positioned underneath and between the tiles. By tightening the wedge or screw cap, adjacent tile edges are levelled in relation to each other.
This gives you greater control during installation and reduces the risk of unwanted height differences.
A tile levelling system does not replace a flat substrate or correct adhesive application. It is a tool that helps position adjacent tiles more accurately in relation to each other during installation.
One of the main reasons to use a tile levelling system is to reduce lippage. Lippage is the difference in height between the edges of two adjacent tiles.
Even a small difference can be visible or noticeable underfoot and make the finished surface look less even. This is particularly noticeable with large-format and rectified tiles.
A tile levelling system gives both professional tilers and experienced DIYers greater control during installation. It is particularly useful when working with large tiles, straight tile edges or narrow grout joints.
A tile levelling system makes it easier to install adjacent tiles accurately at the same height. It also offers several practical benefits during tile installation.
The main benefit of a tile levelling system is that it makes it easier to bring adjacent tiles to the same height. By tightening the clip with a wedge or screw cap, the tiles are clamped in relation to each other and their edges are brought to the same level.
Without a tile levelling system, you need to check the height of the tiles yourself during installation and make manual adjustments where necessary. A levelling system simplifies this process and helps keep the tiles at the same height while the adhesive cures. This reduces lippage and makes it easier to achieve a smooth, even tiled surface.
Because the system levels adjacent tile edges during installation, fewer manual height adjustments are required. This can make tile installation easier and more efficient, particularly when working on larger surfaces.
A tile levelling system can be used for both floor and wall tiles. It is particularly useful for large-format tiles, rectified tiles and installations with narrow grout joints, where small height differences are more noticeable.
With levelling systems where the clip also acts as a spacer, the thickness of the clip determines the distance between the tiles. The system therefore not only helps level the tile edges but also helps maintain a consistent grout joint width.
A tile levelling system does not replace the skill of the tiler. Above all, it gives you greater control over the height and spacing of the tiles during installation.
The basic principle is simple. A levelling clip is positioned underneath the edges of two adjacent tiles. Depending on the system, a wedge is then inserted through the clip or a screw cap is fitted onto it. Tightening the system brings the adjacent tile edges to the same height.
The exact method varies depending on the system. See our instructions for levelling tiles with a wedge system or levelling tiles with a screw system.
To calculate the number of clips required per m², use the Levelit calculator.
The right tile levelling system depends on factors such as the tile thickness, required grout joint width, application and preferred way of working. For example, you can choose between a system with clips and wedges or one with clips and screw caps.
