Fewer or Less?

by Craig Shrives

What Is the Difference between "Fewer" and "Less"?

"Fewer" and "less" are easy to confuse because the rules are not as simple as many people believe.
  • Use "less" when referring to a single item. For example:
    • less money correct tick
    • less cheese correct tick
    • less haste correct tick
  • Use "fewer" when referring to more than one item. For example:
    • fewer coins correct tick
    • fewer pieces of cheese correct tick
    • fewer rats correct tick
  • Use "less than" when referring to a time or a measurement. For example:
    • less than 4 weeks correct tick
    • less than 90 degrees correct tick
    • less than 300 calories correct tick

    "less than 300 calories"

    Not all grammarians agree that "less than 300 calories" is acceptable. Some would prefer "fewer than 300 calories," claiming that only a time or measurement preceded by a number attracts "less than." However, most judge that any noun preceded by a number constitutes a measurement, thereby justifying "less than."

    Our stance? We would use "less than."

    More about "Fewer" and "Less"

    The rules on using "less" and "fewer" mean that "less" is always used with non-countable nouns (as they can't be pluralized), and "fewer" is always used with countable nouns.

    However, remember that there is a quirk. The term "less than" is used with numbers before times and measurements (e.g., less than four days, less than 12 miles).

    Example Sentences with "Fewer" and "Less"

    • There is less cheese on this plate. correct tick
    • (The word "cheese" is singular.)
    • There are fewer pieces of cheese on this plate. correct tick
    • (The word "pieces" is plural.)
    • There are less pigeons in Trafalgar Square than there used to be. wrong cross
    • (should be "fewer pigeons")
    • In the future, there will be less coins in circulation. wrong cross
    • (should be "fewer coins")
    • Fewer people will vote in the forthcoming elections. correct tick

    "Less Than" with Times and Measurements

    Use "less than" (as opposed to "fewer than") with numbers used with times and measurements. For example:
    • Unemployed? You can get a great job in less than three months. How? Learn to program. correct tick (Author Tucker Max)
    • Butterflies cannot fly if their body temperature is less than 86 degrees. correct tick
    The rules with "fewer" and "less" are under change. Few people would challenge "less than" being used with a number that doesn't quantify a date or a measurement.
    • There are fewer than 10 species left. correct tick
    • There are less than 10 species left. correct tick
    • (A strict grammarian might expect this second example to be marked wrong, but nowadays it is "fewer than 10 species" that sounds the more awkward. If you're unsure whether to use "fewer than" or "less than" with a plural noun modified by a number (e.g., 4 cats, 81 books), then use the one that comes naturally. If you opt for "less than," you can claim to be dealing with a measurement, which would justify your decision to use "less than.")
    Look at this example:
    • He wanted to eat fewer calories. He limited himself to less than 2000 calories a day. correct tick
    • (The first "calories" is not measured. The second "calories" is measured.)
    Here is evidence from Google's Ngram viewer proving that "less than" is more common than "fewer than" with a plural noun modified by a number. (Remember that Google's Ngram viewer scans millions of published books. It does not trawl informal texts such as emails, blogs, or social-media entries. This makes it a powerful tool for identifying grammar usage among credible writers.)

    Adopt the Fewer/Less Ruling

    Many people consider the fewer/less ruling to be outdated. It is certainly not well observed by some large reputable companies. For example:


    less bags wrong cross (fewer bags correct tick)
    (Wall*Mart poster)


    less napkins wrong cross (fewer napkins correct tick)
    (Starbucks napkin)


    less emissions wrong cross (fewer emissions correct tick)
    (Volvo advert)

    We advise that you play it safe and adopt the ruling. Using "less" incorrectly may irk your readers. Using "fewer" correctly will showcase your grammar skills.
