Finished floor level (FFL) refers to the final height of a floor after all construction and finishing processes have been completed. It is the level at which the finished floor surface, such as tile, carpet, or hardwood, will be installed. FFL is crucial in construction and design as it ensures proper drainage, accessibility, and alignment with other architectural elements. It is typically measured from a predetermined reference point, such as the top of a foundation or slab.

When a floor is greatly unleveled (> 1/2"), then various things can be done to make it true so that flooring can be laid. That is, to remove any humps or dips in the flooring.When it is impractical to make a floor level, then just make it true.
