The term "folio" (), has three interconnected but distinct meanings in the world of

First, a folio (abbreviated fo or 2
o) is a book or
pamphlet made up of one or more full sheets of paper, on each of which four pages of text are printed, two on each side; each sheet is then folded once to produce two
leaves. Each leaf of a folio book thus is one half the size of the original sheet. Ordinarily, additional printed folio sheets would be inserted inside one another to form a group or "gathering" of leaves prior to binding the book.
Second, folio is used in terms of

"''recto''" and "''verso''" to designate the first and second sides, and (unlike the usage in printing) disregarding whether the leaf concerned is actually physically still joined with another leaf. This usually appears abbreviated: "f26r." means the first side of the 26th leaf in a book.

Format
A folio (from Latin foliō, abl. of folium, leaf) is a book or pamphlet made up of one or more full sheets of paper, on each sheet of which four pages of text are printed, two on each side; each sheet is then folded one time to produce two leaves. Each leaf of a folio book thus is one half the size of the original sheet. This contrasts with a

, folding each sheet three times. Unlike the folio, these last, and further types involving more folds, require the pages of the book to be cut open after binding, which might be done mechanically by the printer, but in historic books was often left for the reader to do with a
paper-knife.
There are variations in how folios are produced. For example, bibliographers call a book printed as a folio (two leaves per full sheet), but bound in gatherings of 8 leaves each, a "folio in 8s."

was printed in about 1455 as a folio, in which four pages of text were printed on each sheet of paper, which were then folded once. The page size is 12 x 17.5 inches (307 x 445 mm), a "double folio" size. Several such folded conjugate pairs of leaves were inserted inside one another to produce the sections or gatherings, which were then sewn together to form the final book. Shakespeare's

In the discussion of manuscripts, a folio means a leaf with two pages, the

the second. In Western books, which are read by turning the pages over from right to left, when the book is begun with the open page edges at the reader's right, the first page to be seen is "folio 1 recto", typically abbreviated to "f1 r.". When this page is turned over "f1 v." is on the left and "f2 r." on the right of the "opening", or two pages that are visible. For books in Arabic, Hebrew, Japanese and other languages, where the book is begun from the back in Western terms, with the open page edges at the reader's left, the numbering also follows the sequence in which the reader encounters.
In the discussion of two-columned manuscripts, a/b/c/d can denote the left and right-hand columns of recto and verso pages (e.g. "f. 150a" and "f. 150b" are the left and right hand columns on the recto page, and "f. 150c" and "f. 150d" the left and right hand columns on the verso page). In the discussion of three-columned manuscripts, notation may make use of folio number + recto/verso + column a/b/c (e.g. "f. 3 v. col. c" references the third column on the verso side of the third folio).
Size
The actual size of a folio book depends on the
size of the full sheet of paper on which it was printed, and in older periods these were not standardized, so the term's meaning is only approximate. Historically, printers used a range of names such as (with approximate maximum page height): Double Elephant Folio (50 inches, 127 cm), Atlas Folio (25 inches, ca 63 cm), Elephant Folio (23 inches, ca 58 cm), Royal Folio (20 inches, ca 51 cm), Medium Folio (18 inches, ca 46 cm), and (the most common) Crown Folio (15 inches, ca 38 cm).
From the mid-nineteenth century, technology permitted the manufacture of large sheets or rolls of paper on which books were printed, many text pages at a time. As a result, it may be impossible to determine the actual format (i.e., number of leaves formed from each sheet fed into a press). The term "folio" as applied to such books may refer simply to the size, i.e., books that are approximately 15 inches (38 cm) tall.
