Quarto

What is Quarto?

In the realm of publishing and printing, a quarto (abbreviated 4to or 2″) refers to a book or pamphlet in which each sheet after printing is folded in half twice to produce four leaves (eight pages).

This folding method creates a page size that is one-quarter of the original full sheet. Historically, the quarto format was a popular size for many books, particularly in the early days of printing and before the widespread adoption of smaller, more portable formats like octavo.

The dimensions of a quarto page can vary significantly depending on the size of the original paper sheet used and the specific way it was folded, but it generally results in a book larger than an octavo but smaller than a folio.

Key Takeaways

• A quarto is a book format determined by the folding of printed sheets.
• Each sheet is folded twice, yielding four leaves (eight pages) per sheet.
• Historically, it was a common book size, larger than an octavo but smaller than a folio.
• The page size of a quarto can vary based on the original paper size.

Understanding Quarto

The term “quarto” originates from the Latin “in quarto,” meaning “in fours.” This directly refers to the process of folding a single large sheet of paper into four sections, which are then bound together to form the pages of a book. This method was prevalent from the 15th century through the 18th century.

The creation of a quarto involves taking a full sheet, folding it in half once, and then folding it in half again. When this folded sheet is cut open, it reveals four pages. When multiple such folded sheets are stacked and bound, they form the complete book. The consistent folding pattern ensures a uniform page size within a single edition.

Different paper sizes historically led to different standard quarto dimensions. For example, a large folio sheet folded into a quarto would result in a large quarto, while a smaller sheet would produce a smaller quarto. The specific dimensions were not standardized in the way modern book sizes are.

Formula (If Applicable)

There is no specific mathematical formula for the dimensions of a quarto. Its size is determined by the original dimensions of the paper sheet used and the folding process. If a paper sheet has dimensions $W \times H$, folding it in half twice to create a quarto typically results in pages with dimensions of approximately $\frac{W}{2} \times \frac{H}{2}$. However, the exact resulting page dimensions depend on how the sheet is cut after folding.

Real-World Example

Many significant works from the Renaissance and Elizabethan eras were published in quarto format. For instance, early editions of William Shakespeare’s plays, such as the First Folio (though technically a folio, many of his individual plays were printed in quarto before that), were often published as quartos. These are often referred to as “Quarto editions” or “Q1,” “Q2,” etc., to denote successive printings of the same play in this format, indicating variations in the text and printing process.

Importance in Business or Economics

In historical book production and trade, the quarto format played a role in the accessibility and cost of books. Larger formats like folios were often more expensive and reserved for significant texts or reference works, while quartos offered a more manageable and affordable size for a wider range of literature, including plays, poetry, and scholarly works.

The consistent folding and page count associated with the quarto format also facilitated standardized printing processes and inventory management for booksellers and publishers. The ability to produce a specific number of pages from a standardized sheet size simplified production planning and cost estimation in the nascent printing industry.

Understanding historical book formats like the quarto is crucial for bibliographers, literary scholars, and collectors who study the evolution of publishing, textual transmission, and the economics of the book trade across different historical periods.

Types or Variations

While the core principle of folding a sheet twice remains, quartos can be categorized by their resulting size, which is dependent on the original paper dimensions.

These are often referred to as:

• Imperial Quarto: Typically around 11 x 15 inches (280 x 380 mm).
• Crown Quarto: Typically around 7.5 x 10 inches (190 x 250 mm).
• Large Quarto: A general term for quartos derived from larger paper sheets.
• Small Quarto: A general term for quartos derived from smaller paper sheets.

The precise dimensions varied by region and printer, but these terms indicate relative size categories.

Related Terms

• Folio: A book format where each sheet is folded once, resulting in two leaves (four pages) per sheet.
• Octavo: A book format where each sheet is folded three times, resulting in eight leaves (sixteen pages) per sheet.
• Duodecimo (12mo): A book format where each sheet is folded four times, resulting in twelve leaves (twenty-four pages) per sheet.
• Binding: The process of physically assembling pages into a book.
