One Tab: How Many Spaces in English?

In the world of typography and typesetting, spacing is a crucial element that can greatly affect the legibility and readability of written text. One aspect of spacing that often raises questions is the number of spaces to use after a period or a full stop. Traditionally, typewriters required two spaces after a period, but with the evolution of technology, such as computer software and digital fonts, the rules regarding spacing have changed. Today, the standard convention in English is to use only one space after a period. In this article, we will explore the reasons behind this change, the impact it has on readability, and address some frequently asked questions regarding this topic.

The History of Spacing After a Period:
To understand the reason behind the shift from two spaces to one, it’s essential to look at the history of typesetting. In the early days of typography, typesetters used varying widths for different characters, which resulted in uneven spacing between words. To improve legibility, extra space was added between sentences by using two spaces after a period. This practice carried over to mechanical typewriters, which used monospaced fonts with fixed spacing between characters. As typewriters became widely popular, the two-space convention after periods became deeply ingrained.

The Shift Towards One Space:
With the advent of digital typesetting and word processing software, typewriters were eventually replaced by computers. The traditional monospaced fonts were replaced by proportional fonts, which adjusted the spacing between characters proportionally to improve readability. These modern fonts account for the adequate natural spacing around punctuation marks, including periods. As a result, the additional space created by using two spaces became unnecessary and even disrupted the flow of text, making it harder to read. Consequently, the one-space convention was adopted as the new standard.

Impact on Readability:
The shift from two spaces to one has been supported by various studies and typographic experts who argue that it enhances readability. The extra space created by using two spaces can interrupt the reader’s rhythm and can be visually distracting, causing fatigue and slower reading times. On the other hand, using one space creates a more consistent and even typographic color, maintaining a smooth and fluid reading experience.

Frequently Asked Questions:
Q: Why was I taught to use two spaces after a period in school?
A: The widespread use of typewriters in schools during the 20th century meant that students were taught typewriter conventions, including the use of two spaces after a period. However, with the shift to digital technology, the one-space convention has become more widely accepted.

Q: Is it wrong to use two spaces after a period?
A: While it is not technically “wrong” to use two spaces, it is considered outdated and inconsistent with modern typesetting practices. Most style guides, including The Chicago Manual of Style and The Associated Press Stylebook, now recommend using only one space.

Q: Does the one-space convention apply to all languages?
A: The one-space convention is primarily applicable to the English language. Some languages, such as French and Spanish, traditionally use two spaces after a period. It is always recommended to consult language-specific typographic conventions when writing in languages other than English.

Q: Can I still use two spaces if I prefer the aesthetic?
A: From a personal preference standpoint, you can use two spaces if you genuinely prefer the aesthetic. However, it is important to note that utilizing two spaces after a period may result in inconsistency when sharing documents with others who adhere to the one-space convention.

Q: How can I update my writing style to adhere to the one-space convention?
A: Breaking a long-standing habit can be challenging, but gradually transitioning to the one-space convention is possible. Start by consciously using one space after every period in new documents. You can also use word processing software’s find-and-replace function to update existing documents.

In conclusion, the shift from two spaces to one after a period in English language writing has evolved with technology and typographic advancements. While the traditional two-space convention had its roots in typewriters, the modern typesetting practices and proportional fonts have made one space the new standard. This shift not only improves readability but also ensures consistency in modern written communication.
