What is the main function of a level in carpentry?

The primary function of a level in carpentry is to check for flatness or plumb. This tool is essential for ensuring that surfaces are perfectly horizontal (level) or vertical (plumb), which is crucial for the structural integrity and aesthetics of a project. Using a level helps carpenters ensure that walls, floors, and other surfaces are straight and true, facilitating the proper installation of doors, cabinets, and other fixtures.

Levels typically have a liquid-filled tube with an air bubble that indicates when the surface is flat or upright. Carpenters rely on this information to make accurate adjustments during construction, preventing issues that could arise from misalignment or unevenness. This contributes to the overall safety and durability of the completed structure.
