What is the primary function of a level in carpentry?

The primary function of a level in carpentry is to determine if a surface is even. Levels are essential tools that help carpenters ensure that surfaces are horizontal (level) or vertical (plumb) as needed for various projects. By using a level, carpenters can check the straightness and alignment of structures such as walls, floors, and cabinets, ensuring that everything is built accurately and functions properly.

This precision is crucial since even minor deviations can lead to issues in the stability and aesthetics of the project. For example, a door that is not level may not close properly, or shelves that are not even can appear crooked and be less stable. Thus, levels play a critical role in achieving professional results in carpentry work.
