Key Differences
The area is specifically used to quantify the space within the boundaries of a two-dimensional figure, calculated in square units (e.g., square meters). On the other hand, size can refer to the dimensions of any object, whether it is two-dimensional or three-dimensional, and is not limited to a specific unit of measure.
While the area is a term often used in the context of geometry, land measurement, or surface coverage, size is a more versatile term that can refer to the volume of a three-dimensional object, the length of an object, or even abstract concepts like the size of a population.
The calculation of area involves specific formulas depending on the shape (e.g., length × width for rectangles), whereas determining the size of an object might involve measurements of length, width, height, or diameter, depending on the object’s shape and the relevant dimensions.
In terms of usage, when one speaks about the area, it is clear that they are referring to the extent of a surface. Size, however, requires context to understand whether it refers to length, volume, weight, or another dimension.
Despite these differences, area and size are related concepts; the area can be considered a component of size when describing flat surfaces or components of three-dimensional objects. For example, the size of a park might be described by its area in square kilometers.
