length

Length is a measurement of how long something is from one end to the other. Think of it as the distance along the longest side of an object, like the height of a person or the width of a table. It's a fundamental way to describe how big or small something is in one dimension. Length can be measured using various tools, such as a ruler, tape measure, or a laser distance meter. It helps us compare, fit, and plan things in everyday life, construction, and many scientific fields.
