This document outlines common codes and conventions used on magazine covers, including: 1) The masthead displays the magazine title in a unique font across the full page width, always as the largest text. 2) The main cover line is the largest text anchoring the main image and provides details in sublines. 3) Additional elements like the barcode, buzzwords, color schemes, images, cover lines, and puffs are used to promote articles and incentives to entice readers. 4) Positioning statements, subsidiary images, and incentives in the pug corner further communicate what readers will find inside.
