What does life-sized mean?

Life-sized means having the same size as an original or being the same size as in life or nature. The term denotes a quality that is generally assigned to items or objects that are representations of people or living things.

The term “life-sized’ is synonymous with the term “life-size," and the use of either term is considered correct in most cases, with little or no significance attached to the past tense of the word "size." Both terms frequently describe works of art such as drawings, paintings and sculpture. For example, a life-sized statue is one that is the same size as the object or person it represents.
