In graphic design and advertising, a comprehensive layout or comprehensive, usually shortened to comp, is the page layout of a proposed design as initially presented by the designer to a client, showing the relative positions of text and illustrations before the specific content of those elements has been decided on, as a rough draft of the final layout in which to build around.

The illustration element may incorporate stock photography, clip art, or other found material that gives an idea of what should be visually communicated, before entering any negotiations concerning the rights to use a specific image for the purpose. Picture agencies may encourage such use free of charge, in the hope that the comp image (sometimes referred to as a "positional" image) will end up being used in the final product. For this reason, it is sometimes mistakenly believed that "comp" is short for "complimentary," as it is in some other promotional contexts.

Even in the age of rapid desktop publishing software, comps may be developed using hand-rendering techniques and materials to avoid investing too much time on the computer before client approval of the idea, depending on the complexity of the production task. A hand-rendered comp may be useful in helping the client refrain from "nitpicking" the production quality and focus on the design idea.

"Comp" may also stand for composition or composite layout.
