Q:
# What is a linear inch ?

**A linear inch is a unit of measurement that corresponds to one-twelfth of a foot.** A standard inch is the same as a linear inch, because inches themselves are units of linear measure. Linear measures are one-dimensional, measuring length or distance along only one geometrical axis.

By contrast, square inches, square feet and other square measurements are two-dimensional measures. Square measurements incorporate length and width, and are found by multiplying one by the other. Linear measurements, on the other hand, can be found simply by using a ruler or similar tool. Linear inches are used to express the perimeter of rooms, the height of people or objects and the length of small objects like a shoelace or a sheet of paper.
