Most comic books, like most magazines, are published in a portrait format.
However, there are a few comics creators who have dabbled with sideways comics, where the comic is turned on its side, in a landscape fashion, and the story is told sequentially that way.
The subtle difference in available dimensions opens up new storytelling possibilities if people are savvy enough to explore them.
Can we create a definitive list of sideways comics? Mainstream, manga, alternative, underground, reprint collections, what have you.
Incidentally, sideways comics are not the same as so-called “widescreen” comics like the THE AUTHORITY and THE ULTIMATES and ULTIMATES 2, where the panels are arranged from edge to edge on a portrait format.
Frank Miller’s 300 qualifies as a sideways comic: even though the initial monthly series was published as a portrait comic, a closer inspection reveals it’s a sideways comic using the whole folded sheet: normally two pages as canvas.
My choice: Bill Watterson’s CALVIN & HOBBES Sunday comics collections when he came back from his sabbatical with a revamped Sunday format: IT’S A MAGICAL WORLD, THE TEN ANNIVERSARY COLLECTION and THERE’S TREASURE EVERYWHERE.
