Tile lippage refers to the condition where one edge of a tile sits higher than the edge of the adjacent tile. Because no tile is perfectly flat, the industry establishes standards for allowable variation. For large-format tiles, the tolerance is slightly more generous due to the natural curvature inherent in the manufacturing process of these larger pieces. However, for smaller tiles, the tolerance is much tighter. An unacceptable level of lippage is not only a tripping hazard but also an aesthetic concern, creating shadows that highlight the uneven transitions. If the lippage exceeds industry standards, it is typically considered an installation error resulting from an uneven subfloor, improper setting techniques, or lack of leveling systems. If you believe your floor exceeds acceptable levels, it is important to have the installation inspected to verify whether the variation falls within the manufacturer's or the Tile Council of North America's stated tolerances. Correcting extreme lippage usually requires removing the affected tiles or, in severe cases, a full re-installation.
