In graphic design, what does it mean to change the scale of an object?

Changing the scale of an object in graphic design specifically refers to altering its size. This action can involve making the object larger or smaller while maintaining its proportions, so that it fits better within a layout or meets specific design requirements. Scaling is an essential tool in design, as it allows designers to create a visual hierarchy, emphasize important elements, or ensure coherence among various components within a project.

The other options relate to different aspects of graphic design. Adjusting the resolution pertains to image clarity and quality rather than size. Repositioning involves moving the object from one location to another within the design layout without changing its size. Changing the object's color focuses on its appearance but does not affect its size or scale. Thus, the core idea of scale change distinctly identifies with resizing rather than these other modifications.
