A device used to measure true horizontal or relative heights, frequently used in surveying and construction.
Plumb and Level[]
The definition of plumb means measuring with a level tool up and down or vertical positions.
On the other hand, a level means measuring with the level tool horizontal or side to side positions. You check these two measurements with a plumb stick, otherwise known as a level.
Choosing a Level[]
Levels come in all shapes and sizes. It seems like there is almost a different level for every job. A good all purpose level to have around the house is a 24 inch or two foot level. A two-foot level is perfect for household or construction projects.
