How To Write Out Numbers: A Comprehensive Guide for Writers and Editors

Writing numbers correctly can seem like a minor detail, but it significantly impacts readability and professionalism. This comprehensive guide will equip you with the knowledge to confidently handle numerical representation in any writing context. We’ll explore the various styles, exceptions, and best practices to ensure your writing is polished and accurate.

When to Write Out Numbers vs. Use Numerals

The decision to write out numbers (e.g., “one,” “two”) or use numerals (e.g., “1,” “2”) depends largely on style guides and context. Generally, write out numbers from zero to nine and use numerals for numbers ten and above. However, this is a guideline, not a hard and fast rule. Consistency is key.

Exceptions to the General Rule

There are several situations where the general rule bends. For instance, you’ll typically use numerals for:

  • Dates: “January 1, 2024”
  • Times: “3:00 PM”
  • Measurements: “5 feet tall”
  • Addresses: “123 Main Street”
  • Percentages: “25%”
  • Page numbers: “Page 12”
  • IDs or serial numbers: “Order #12345”

Numbers at the Beginning of a Sentence

A common stylistic issue arises when a number starts a sentence. The general rule is to always write out numbers at the beginning of a sentence. For example, instead of “15 people attended,” write “Fifteen people attended.” However, if rewriting the sentence is cumbersome, it’s acceptable to restructure the sentence to avoid this issue.

Using Hyphens with Numbers

Hyphens play a crucial role in correctly writing compound numbers. Use hyphens with compound numbers from twenty-one to ninety-nine. For example: twenty-one, thirty-two, forty-three, etc. This rule also extends to hyphenated fractions like “two-thirds” or “one-half.”

Handling Large Numbers

For extremely large numbers, consider using a combination of numerals and words for better readability. For example, instead of “1,234,567,” you might write “1.23 million.” This enhances clarity and avoids overwhelming the reader with a long string of digits.

Consistency in Style

Maintaining consistency is paramount. Choose a style guide (such as AP, Chicago, or MLA) and adhere to its rules throughout your writing. Inconsistent use of numbers can detract from the overall professionalism of your work.

Numbers in Lists and Tables

When presenting numbers in lists or tables, consistency is vital. Use either numerals or written-out numbers consistently throughout the list or table, depending on the style guide you are following.

Handling Ordinal Numbers

Ordinal numbers (first, second, third, etc.) generally follow the same rules as cardinal numbers (one, two, three, etc.). Write them out for numbers one through nine, and use numerals for numbers ten and above, unless a style guide dictates otherwise.

Using Abbreviations for Numbers

While generally avoided in formal writing, abbreviations like “No.” (number) and “pp.” (pages) are acceptable in certain contexts, particularly when referring to page numbers or item numbers. However, use these sparingly and ensure consistency.

Specific Cases: Money and Decimal Numbers

Money amounts are typically written with numerals, including the currency symbol. For instance, “$25,” not “twenty-five dollars.” Decimal numbers should also use numerals, and be clear about the unit of measurement.

Conclusion

Mastering the art of writing numbers correctly enhances the clarity and professionalism of your writing. By understanding the general rules, exceptions, and the importance of consistency, you can confidently navigate the nuances of numerical representation in your writing. Remember to always prioritize readability and choose a style guide to maintain consistency throughout your work. Careful attention to these details elevates your writing to a higher level of polish and credibility.
