# Size vs. Dimension — What's the Difference?

Edited by Tayyaba Rehman — By Fiza Rafique — Updated on November 2, 2023
Size refers to the magnitude or extent of something, often measured in units, whereas dimension denotes a measurable extent of a particular kind, such as length, width, or height.

## Key Differences

Size is a general term that refers to how big or small something is, often quantifiable by units of measurement like meters or kilograms. Dimensions are specific to the proportions and measurable extents that define the shape and scale of an object, such as length, width, and height.

While size is a scalar quantity giving a sense of scale or amount, dimensions are often given in a series of numbers, which, taken together, define the space an object occupies. Size is a single or multi-dimensional attribute, but dimensions are always multi-faceted and directional.

For instance, the size of a room might be described as small, medium, or large, which is a subjective measure. The dimensions of the same room would be expressed in terms of its length, width, and height in units like feet or meters, providing an objective measure.

When buying clothing, size might be indicated by a number or letter, and it refers to the overall fit. In contrast, the dimensions of a piece of fabric used to make the clothing would include specific measurements such as the length and width of the material.

Understanding the size of an object often requires knowing its dimensions, but dimensions alone do not describe the size. Size can imply overall space occupancy or capacity, while dimensions provide the detailed measurements of each aspect of an object's shape.

#### Dimension

In physics and mathematics, the dimension of a mathematical space (or object) is informally defined as the minimum number of coordinates needed to specify any point within it. Thus a line has a dimension of one (1D) because only one coordinate is needed to specify a point on it – for example, the point at 5 on a number line.
