lifesize

The word "lifesize" describes something that is made or shown at its actual size, matching the dimensions of the real thing. It does not simply mean "big." It means the scale is true to life. If a portrait is painted lifesize, the person in it is shown neither smaller nor larger than they would appear in real life.

The word is often used for physical things such as statues, models, replicas, and display figures. A lifesize cardboard cutout, for example, is meant to look as tall as the actual person. Museums may show lifesize models of animals or ancient creatures so visitors can better understand their real size. Stores and advertisers also use lifesize images or displays to help people picture how large something really is.

The term is not limited to people or animals. You might also see a lifesize model of a car, a room, or a piece of historical equipment. In each case, the idea is the same: the object is shown at the same size as the original so people can judge its scale easily. This spelling is also often written as "life-size." When you hear "lifesize," think of something that matches the real thing in size as closely as possible.
