The standard size of comic books is 6 5/8" x 10 1/4" (a strange size, I know). Most comics are drawn at a larger scale so that when they're shrunk down to the standard size for printing, the detail will be finer (and the mistakes less apparent) than if it were drawn to size. Depending on the project, I work at either 133% or 150%.
In the the sizes of books had names. Most of these names included the size of a signature. A book consists of a number of folded sheets of paper. A printed sheet of paper can be folded in half to make 4 pages; this is a folio. If a sheet is folded in half, and then folded in half again, it will have 8 pages, and so on. The number of pages on a folded sheet is always a power of 2.
The size and proportions of a book will thus depend on the size of the original sheet of paper used in producing the book. For example, if a sheet by is used to print a quarto, the resulting book will be approximately tall and wide, before trimming. Because the size of paper used has differed over the years and localities, the sizes of books of the same format will also differ. A typical octavo printed in Italy or France in the thus is roughly the size of a modern book, but an English octavo is noticeably larger, more like a modern or hardcover novel.
The size of a is generally measured by the height against the width of a leaf, or sometimes the height and width of its cover. A series of terms is commonly used by and for the general sizes of modern books, ranging from (the largest), to (smaller) and (still smaller). Historically, these terms referred to the format of the book, a technical term used by printers and to indicate the size of a leaf in terms of the size of the original sheet. For example, a quarto (from Latin , ablative form of , fourth) historically was a book printed on a sheet of paper folded twice to produce four leaves (or eight pages), each leaf one fourth the size of the original sheet printed. Because the actual format of many modern books cannot be determined from examination of the books, bibliographers may not use these terms in scholarly descriptions.
