Letters are not typically double spaced in standard modern writing, whether in digital documents or printed manuscripts. The practice of double spacing primarily survived the transition from typewriters to computers in professional and academic settings, where the monospaced fonts of typewriters demanded extra space between sentences for readability. Today, most style guides for general publishing, journalism, and business communication advocate for single spacing to create a cleaner, more modern appearance that is easier to scan on screens and saves physical paper.
The Historical Context of Double Spacing
The origin of double spacing after periods is deeply rooted in the limitations of manual typewriters from the early 20th century. These machines used monospaced fonts, where every character, whether an "i" or a "w," occupied the same amount of horizontal space. This uniformity created awkward gaps in the flow of text, and the extra space after a period acted as a visual delimiter, helping the reader’s eye recognize the end of a sentence. The typewriter era ingrained a habit that persisted long after technology evolved, leading to a lingering misconception that double spacing is the standard rule for professional writing.
Typewriters vs. Modern Word Processing
With the advent of proportional fonts in computers and word processors like Microsoft Word and Google Docs, the necessity for double spacing vanished. Proportional fonts adjust the width of each character to fit naturally, so the "r" in "arrow" sits closer to the "o" than the "i" does, creating a balanced and elegant text block. In this modern context, double spacing creates excessive white space, disrupts the visual rhythm of a paragraph, and can make text appear disjointed. Major style guides, including the APA, MLA (with specific exceptions for student drafts), and the Chicago Manual of Style, now recommend single spacing for the body of text.
Specific Style Guide Recommendations
For most professional and academic writing, the default should always be single spacing within paragraphs. However, specific contexts may require variations, and understanding these nuances is key to presenting a polished document. Always defer to the style guide requested by your instructor, publisher, or employer, as institutional standards can override general best practices.
When to Use Double Spacing
Editing and Proofreading: Marginal notes and corrections are easier to read when lines are separated.
Student Drafts: Many instructors require double spacing on rough drafts to provide space for feedback.
Specific Manuscript Submissions: Some older academic fields or traditional publishing houses may still request it.
The Standard for Final Documents
In the final version of a report, essay, novel, or business proposal, single spacing is the expected norm. The only common exception within final documents is the space between distinct blocks of text, such as before and after headings or block quotes, where a double space (or a designated paragraph spacing) improves structure without cluttering the page. The key is consistency; applying one standard spacing method throughout the document ensures a cohesive and professional look.
Practical Application and Digital Design
Adjusting spacing in digital documents is a straightforward process, but it requires intention. Simply hitting the space bar twice after every period is a habit that undermines the visual integrity of your work. Instead, utilize the paragraph settings in your word processor to control "line spacing" and "space after" parameters. This approach ensures that your text remains uniform, avoids the trap of inconsistent spacing, and adheres to the clean standards of contemporary graphic design, where white space is a deliberate tool rather than an accident of technology.
