These are some double page spread examples from a popular basketball magazine in America named Slam.
Although these 2 articles are more than just double-page spreads, they follow the same format of a double page spread. Key conventions that I have noticed are that pictures play a bigger role than the text, as on every page the pictures stand out and fill the empty space, whereas text looks to play a secondary role (although the text is undoubtedly still important). This allows the pictures to be dynamic and in some cases the pictures do speak more than the words. This means that I will look to fill space with large pictures and the text will fit around it.
