Comparison of some book sizes based on American Library Association.

The size of a book is generally measured by the height against the width of a leaf, or sometimes the height and width of its cover. [2] A series of terms is commonly used by libraries and publishers for the general sizes of modern books, ranging from folio (the largest), to quarto (smaller) and octavo (still smaller). Historically, these terms referred to the format of the book, a technical term used by printers and bibliographers to indicate the size of a leaf in terms of the size of the original sheet. For example, a quarto (from Latin quartō, ablative form of quartus, fourth [3] ) historically was a book printed on sheets of paper folded in half twice, with the first fold at right angles to the second, to produce 4 leaves (or 8 pages), each leaf one fourth the size of the original sheet printed – note that a leaf refers to the single piece of paper, whereas a page is one side of a leaf. 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.

Book formats

In the hand press period (up to about 1820) books were manufactured by printing text on both sides of a full sheet of paper and then folding the paper one or more times into a group of leaves or gathering . The binder would sew the gatherings (sometimes also called signatures) through their inner hinges and attached to cords in the spine to form the book block. Before the covers were bound to the book, the block of text pages was sometimes trimmed along the three unbound edges to open the folds of the paper and to produce smooth edges for the book. When the leaves were not trimmed, the reader would have to cut open the leaf edges using a knife.

Books made by printing two pages of text on each side of a sheet of paper, which is then folded once to form two leaves or four pages, are referred to as folios (from Latin, foliō, ablative of folium, leaf [3] ). Those made by printing four text pages on each side of a sheet of paper and folding the paper twice to form a gathering containing four leaves or eight pages are called quartos (fourths). Similarly, books made by printing eight pages of text on each side of a sheet, which was then folded three times to form gatherings of eight leaves or sixteen pages each, are called octavos . The size of the resulting pages in these cases depends, of course, on the size of the full sheet used to print them and how much the leaves were trimmed before binding, but where the same size paper is used, folios are the largest, followed by quartos and then octavos. [4] :80–81 The proportion of leaves of quartos tends to be squarer than that of folios or octavos. [5] :164

These various production methods are referred to as the format of the book. These terms are often abbreviated, using 4to for quarto, 8vo for octavo, and so on. The octavo format, with eight leaves per gathering, has half the page size of the quarto format before trimming. Smaller formats include the duodecimo (12mo or twelvemo), with twelve leaves per sheet and pages one-third the size of the quarto format, and the sextodecimo (16mo or sixteenmo), with sixteen leaves per sheet, half the size of the octavo format and one quarter the size of the quarto. The vast majority of books were printed in the folio, quarto, octavo or duodecimo formats. [4] :82

There are many variations in how such books were produced. For example, folios were rarely made by simply binding up a group of two leaf gatherings; instead several printed leaf pairs would be inserted within another, to produce a larger gathering of multiple leaves that would be more convenient for binding. [5] :30–31 For example, three two-leaf printed sheets might be inserted in a fourth, producing gatherings of eight leaves or sixteen pages each. Bibliographers still refer to such books as folios (and not octavos) because the original full sheets were folded once to produce two leaves, and describe such gatherings as folios in 8s. Similarly, a book printed as an octavo, but bound with gatherings of four leaves each, is called an octavo in 4s. [5] :28

In determining the format of a book, bibliographers will study the number of leaves in a gathering, their proportion and sizes and also the arrangement of the chain lines and watermarks in the paper. [4] :84–107

In order for the pages to come out in the correct order, the printers would have to properly lay out the pages of type in the printing press. For example, to print two leaves in folio containing pages 1 through 4, the printer would print pages 1 and 4 on one side of the sheet and, after that has dried, print pages 2 and 3 on the other side. If a printer was printing a folio in 8s, as described above, he would have to print pages 1 and 16 on one side of a leaf with pages 2 and 15 on the other side of that leaf, etc. The arrangement of the pages of type in the press is referred to as the imposition and there are a number of methods of imposing pages for the various formats, some of which involve cutting the printed pages before binding. [4] :80–110

See Further reading for more on imposition schemes.

Modern book production

As printing and paper technology developed, it became possible to produce and to print on much larger sheets or rolls of paper and it may not be apparent (or even possible to determine) from examination of a modern book how the paper was folded to produce them. For example, a modern novel may consist of gatherings of sixteen leaves, but may actually have been printed with sixty-four pages on each side of a very large sheet of paper. [6] :429 Similarly, the actual printing format cannot be determined for books that are perfect bound, where every leaf in the book is completely cut out (i.e., not conjugate to another leaf as in gatherings) and is glued into the spine. Modern books are commonly called folio, quarto and octavo based simply on their size rather than the format in which they were actually produced, if that can even be determined. Scholarly bibliographers may describe such books based on the number of leaves in each gathering (eight leaves per gathering forming an octavo), even where the actual number of pages printed on the original sheet is unknown [4] :80–81 or may reject the use of these terms for modern books entirely. [note 1]

Today, octavo and quarto are the most common book sizes, but many books are produced in larger and smaller sizes as well. Other terms for book size have developed, an elephant folio being up to 23 inches tall, an atlas folio25 inches, and a double elephant folio50 inches tall.

Paper sizes

During the hand press period, full sheets of printing paper were manufactured in a great variety of sizes which were given a number of names, such as pot, demy, foolscap, crown, etc. [7] [8] These were not standardized and the actual sizes varied across countries and times. [4] :67–70,73–75

The size and proportions of a book depend on the size of the original full sheet. If a sheet 19 inches (480 mm) by 25 inches (640 mm) is used to print a quarto, the resulting untrimmed pages, will be approximately half as large in each dimension: width 9+12 inches (240 mm) and height 12+12 inches (320 mm). An octavo page, oriented a quarter turn from the full sheet, would have height ½ × 19 = 9+12 inches (240 mm) and width ¼ × 25 = 6+14 inches (160 mm). The sizes of books of the same format will differ in proportion to the full sheets used to print them. For example, a typical octavo printed in Italy or France in the 16th century is roughly the size of a modern mass market paperback book, but an English 18th-century octavo is noticeably larger, more like a modern trade paperback or hardcover novel.

Common formats and sizes

United States

The following table is adapted from the scale of the American Library Association, [1] [9] which uses a basis sheet of 19-by-25-inch (483 by 635 mm) [10] which is, confusingly if not explained by the source, half the text/book stock sheet of 25-by-38-inch (635 by 965 mm)), and in which size refers to the dimensions of the cover (trimmed pages will be somewhat smaller, often by about 14 inch or 5 mm [2] ). The words before octavo signify the traditional names for unfolded paper sheet sizes. Other dimensions may exist as well. [8] [11] US Trade size corresponds with octavo and is popular for hardbacks. Mass market paperback corresponds with duodecimo.

A book is a medium for recording information in the form of writing or images. Books are typically composed of many pages, bound together and protected by a cover. Modern bound books were preceded by many other written mediums, such as the codex and the scroll. The book publishing process is the series of steps involved in their creation and dissemination.

<span class="mw-page-title-main">Codex</span> Historical ancestor of the modern book

The codex was the historical ancestor of the modern book. Instead of being composed of sheets of paper, it used sheets of vellum, papyrus, or other materials. The term codex is often used for ancient manuscript books, with handwritten contents. A codex, much like the modern book, is bound by stacking the pages and securing one set of edges by a variety of methods over the centuries, yet in a form analogous to modern bookbinding. Modern books are divided into paperback and those bound with stiff boards, called hardbacks. Elaborate historical bindings are called treasure bindings. At least in the Western world, the main alternative to the paged codex format for a long document was the continuous scroll, which was the dominant form of document in the ancient world. Some codices are continuously folded like a concertina, in particular the Maya codices and Aztec codices, which are actually long sheets of paper or animal skin folded into pages. In Japan, concertina-style codices called orihon developed during the Heian period (794–1185) were made of paper.

<span class="mw-page-title-main">Octavo</span> Technical term describing the format of a book

Octavo, a Latin word meaning "in eighth" or "for the eighth time", is a technical term describing the format of a book, which refers to the size of leaves produced from folding a full sheet of paper on which multiple pages of text were printed to form the individual sections of a book. An octavo is a book or pamphlet made up of one or more full sheets on which 16 pages of text were printed, which were then folded three times to produce eight leaves. Each leaf of an octavo book thus represents one eighth the size of the original sheet. Other common book formats are folios and quartos. Octavo is also used as a general description of the size of books that are about 8 to 10 inches tall, and as such does not necessarily indicate the actual printing format of the books, which may even be unknown as is the case for many modern books. These terms are discussed in greater detail in book sizes.

A loose leaf is a piece of paper of any kind that is not bound in place, or available on a continuous roll, and may be punched and organized as ring-bound or disc-bound. Loose leaf paper may be sold as free sheets, or made up into notepads, where perforations or glue allow them to be removed easily. "Leaf" in many languages refers to a sheet or page of paper, as in Folio, as in feuille de papier (French), hoja de papel (Spanish), foglio di carta (Italian), and ルーズリーフ.

<i>Wasōbon</i> Books in Japan

Wasōbon is a traditional book style in Japan that dates from the late eighth century AD with the printing of "Hyakumantō Darani" during the reign of Empress Shōtoku (764-770AD). Most of the books were hand-copied until the Edo period (1603–1867), when woodblock printing became comparatively affordable and widespread. Movable-type printing had been used from the late 16th century, but for various aesthetic and practical reasons woodblock printing and hand-copied remained dominant until much later. Japanese equivalents for "book" include (hon) and 書籍 (shoseki). The former term indicates only bound books, and does not include scrolls. The latter is used for printed matter only. The most general term is 書物 (shomotsu), which means all written or printed matter that has been collected into a single unit, regardless of construction.

Bookbinding is the process of building a book, usually in codex format, from an ordered stack of paper sheets with one's hands and tools, or in modern publishing, by a series of automated processes.

One can also use loose-leaf rings, binding posts, twin-loop spine coils, plastic spiral coils, and plastic spine combs, but they last for a shorter time. Next, one encloses the bound stack of paper in a cover. Finally, one places an attractive cover onto the boards, and features the publisher's information and artistic decorations.
