The term "extra-large" refers to a size designation that is larger than the standard large size. It is commonly used in clothing, food portions, and various products to indicate that the item is designed for individuals or situations that require more space or volume. For example, an extra-large shirt typically has a greater width and length compared to large shirts. In the context of clothing, extra-large sizes are often labeled as XL and are intended to accommodate a wider range of body types. In food service, an extra-large pizza may have a larger diameter than a standard large pizza, providing more slices and serving more people.
