Fewer vs less: the counting rule, the exceptions editors accept, and examples
Use fewer for things you can count: fewer chapters, fewer readers, fewer typos. Use less for amounts you measure: less time, less money, less doubt. Dictionary.com sums it up: "If you can count it, go for fewer. If you can't, opt for less." Here are the exceptions editors accept, examples and how to check your manuscript.
The rule
Fewer goes with plural nouns you count one by one. Less goes with nouns that name an amount or a mass, which stay singular.
- Fewer: fewer pages, fewer interviews, fewer clients, fewer mistakes
- Less: less time, less research, less money, less pressure
A quick test: can you put a number in front of the noun? "Three pages" works, so it is fewer pages. "Three researches" does not, so it is less research.
The Elements of Style (1918) put it in five words: "Less refers to quantity, fewer to number." It adds that the two can mean different things: "His troubles are less than mine" means they are not as great; "His troubles are fewer than mine" means there are not as many.
The exceptions editors accept
Less is standard with numbers that stand for an amount rather than a set of separate things:
- Money: "The ebook costs less than $10." (You are thinking of a sum, not ten separate dollars.)
- Time: "I wrote the first draft in less than six months."
- Distance and weight: "The printer is less than 20 miles away."
- Round totals: The Elements of Style says "The signers of the petition were less than a hundred" is correct, because the round number works like a single amount.
- "Or less" after a number: "Keep the subtitle to 12 words or less" is common in everyday writing. In a book, "or fewer" is the safe choice.
Why "10 items or less" is everywhere
Dictionary.com points out that less has been used with countable things since Old English, the time of Alfred the Great. That long history is why supermarket signs say "10 Items or Less" and why "less people" sounds normal in conversation. Wiktionary's usage note says the same: less has been widely used as a synonym for fewer since it first appeared. But many readers have learned the counting rule, and to them "less" with a plural noun sounds wrong. In a book, follow the rule.
Examples
| Sentence | Word | Why |
|---|---|---|
| The second draft had ___ chapters than the first. | fewer | Chapters are counted |
| I spent ___ time on research this year. | less | Time is an amount |
| We got ___ than 50 reviews in the first month. | fewer | Separate reviews, counted |
| The audiobook runs ___ than eight hours. | less | A span of time |
| Cut the intro to ___ than 1,000 words. | fewer | Words are counted one by one |
| Printing in black and white costs ___ money. | less | Money as an amount |

Checking your manuscript
Search your file for "less" and look at the noun that follows. If it is plural and countable (people, books, words, steps), change it to fewer. Leave it where the noun is an amount, or a number that stands for money, time or distance. A copy editor will catch the rest; see what a copy editor does. For more word choices editors flag, see who vs whom and that vs which.
Start here: search your manuscript for "less people" and "less than" followed by a number of things (copies, clients, pages). Change those to "fewer."
Common questions
What is the difference between fewer and less?
Fewer is for things you can count one by one: fewer pages, fewer interviews, fewer typos. Less is for amounts you measure rather than count: less time, less money, less confidence. If you can put a number in front of the noun, use fewer.
Is it 10 items or less or 10 items or fewer?
By the usage rule, "10 items or fewer," because items are counted. Dictionary.com notes that less has been used this way since Old English, which is why "10 items or less" signs are so common, but many readers still notice it.
Is it less than or fewer than with numbers?
With a number of separate things, fewer than: "fewer than 200 copies sold." With a number that stands for an amount, such as money, time, distance or a round total, less than is accepted: "less than $20," "less than three hours." The Elements of Style gives "less than a hundred" as correct for the same reason.
Is less people wrong?
Most editors will change it to fewer people. Less with a plural count noun is common in speech and has a long history, but in a book it reads as a mistake to many readers.
