If you’ve ever felt the judgmental stare of a grammar enthusiast while standing in a “10 Items or Less” supermarket lane, you’ve encountered the less vs. fewer debate. While the lines between formal and informal English are blurring, the distinction remains a hallmark of high-quality, professional writing.

1. The Golden Rule
The easiest way to decide which word to use is to look at the noun that follows it.
- Fewer is for countable things. If you can count them one by one (1, 2, 3…), use fewer.
- Less is for uncountable things. If it’s a mass, a bulk, or an abstract concept, use less.
| Use Fewer for: | Use Less for: |
| Fewer calories | Less food |
| Fewer assignment | Less homework |
| Fewer buttons | Less clothing |
| Fewer people | Less humanity |
2. The “Number vs. Amount” Test
If you are still unsure, ask yourself these two questions:
- Can I ask “How many?” If yes, use fewer.
- Can I ask “How much?” If yes, use less.
Example: You have fewer coins (How many?), but less money (How much?).
3. The 4 Big Exceptions (The “Singular Idea” Rule)
This is where most writers trip up. Standard English accepts less for certain countable items when they are viewed as a single bulk amount or a measurement.
A. Time
Even though minutes and hours are countable, we view time as a continuous flow.
- Correct: “The meeting lasted less than 30 minutes.”
- Incorrect: “The meeting lasted fewer than 30 minutes.”
B. Money
We treat sums of money as a total amount rather than individual bills.
- Correct: “The book costs less than $20.”
C. Distance and Weight
Measurements are considered singular concepts.
- Correct: “He lives less than 5 miles away.”
- Correct: “The suitcase weighs less than 50 pounds.”
D. “One Less”
This is a fixed idiomatic exception. Even for countable items, we always say “one less.”
- Correct: “That’s one less problem to deal with.” (Not “one fewer problem”).
4. The Supermarket Controversy: “10 Items or Less”
Technically, according to the 1770 rule popularized by Robert Baker, a grocery sign should read “10 Items or Fewer” because you can count the apples and cans.
However, “10 Items or Less” has become so ingrained in the English lexicon that most style guides now accept it as a standard idiomatic phrase. If you are writing a formal essay, use fewer; if you are writing a casual blog post, either is generally accepted.
Summary Checklist
- Is it a plural noun you can count? Use Fewer.
- Is it a singular mass or abstract concept? Use Less.
- Is it time, money, distance, or weight? Use Less.
- Are you using the phrase “One less”? Always use Less.
FAQ: Less or Fewer?
Is “less people” grammatically correct?
In formal writing, no. It should be fewer people because people are countable. However, in casual speech, “less people” is becoming increasingly common.
Do I use less or fewer for percentages?
Generally, use less. (e.g., “Less than 20% of the population”). Even if the percentage refers to countable people, the percentage itself is considered a singular mathematical amount.
What about “no less than”?
“No less than” is an idiom often used for emphasis, even with countable numbers. (e.g., “No less than 50 people showed up”). While “no fewer than” is more “correct,” “no less than” is widely accepted for stylistic flair.
