Criteria for effective logo design: Here is how I measure the quality of solutions for a logo design... Simple: reduced to it's most necessary visual form, and still able to evoke or engage. Appropriate: relevant to the industry, target audience, and needs defined. Memorable: distinct enough to stand out from the crowd, not appear commonplace, and creates retention. Conceptual: rooted in a good and strategic idea, be it literal or abstract. Timeless: not given to trends or fashions, so as to be enduring as long as possible. Graphic: recognizable even when words or type are not always legible, and functional in it's most basic form. Gestalt: through visual suggestion, more is expressed than the total elements might indicate.
