Fewer vs Less: Examples & How to Fix It
Use fewer for things you can count individually (“fewer cars”, “fewer mistakes”) and less for amounts you can’t count (“less traffic”, “less time”). If you can put a number in front and pluralize it, use fewer. Paste your own sentence into the free checker below to fix it in one click.
Use fewer for things you can count individually (“fewer cars”, “fewer mistakes”) and less for amounts you can’t count (“less traffic”, “less time”). If you can put a number in front and pluralize it, use fewer.
How it works
- 1Spot the pattern. Ask whether the noun is countable. “Three cars” works, so it’s countable → fewer. “Three waters” doesn’t, so it’s uncountable → less.
- 2Apply the rule. If the noun has a plural form you could count, switch to fewer. Exceptions exist for distances, money, and time treated as a single amount (“less than five miles”, “less than $20”).
- 3Check your sentence. Paste your text into the grammar checker below — it flags the issue and shows the correction.
- 4Re-read it. Read the corrected version aloud to confirm it says exactly what you meant.
The rule
Fewer goes with countable (plural) nouns; less goes with uncountable (mass) nouns. “Fewer cars on the road means less traffic.”

The most common mistake
Saying “less items” or “10 items or less” — items are countable, so it should be “fewer items” / “10 items or fewer”. If you’re not sure whether your sentence has the problem, paste it into the checker above — it catches this and explains the fix in plain language.
| ❌ Incorrect | ✓ Corrected | Why |
|---|---|---|
| This lane is for 10 items or less. | This lane is for 10 items or fewer. | Items are countable |
| We made fewer progress this week. | We made less progress this week. | Progress is uncountable |
| Fewer water means smaller plants. | Less water means smaller plants. | Water is uncountable |
Frequently asked questions
Fewer or less — which is right?
Fewer for countable nouns (fewer people); less for uncountable ones (less water). “Fewer cars on the road means less traffic.”
Why is “10 items or less” considered wrong?
Items can be counted, so grammar guides prefer “fewer”. Many stores use “less” colloquially, but “10 items or fewer” is the correct form.
