Fewer or Less: The Complete Guide to Using Them Correctly

Fewer is used with things you can count, while less is used with things you cannot count. A simple trick is: if you can count the items one by one, use fewer. If you cannot, use less.

A few years ago, I was editing an article for a client when I spotted a sentence that read, “There were less mistakes this time.” It looked normal at first glance. Many people say it every day. Yet something felt wrong.

That tiny word choice changed the whole sentence.

I have spent more than ten years teaching English and editing writing. One grammar question appears again and again: Should I use fewer or less? Even native English speakers mix them up. You hear both on TV, read both online, and see both in stores. That makes the rule seem confusing.

The good news is that it is much easier than many people think.

By the end of this guide, you will know exactly when to use fewer and less. You will also learn the history behind the rule, common mistakes to avoid, real-life examples, and simple tips that help you remember the difference forever.

Let’s begin with the quick answer.

Fewer or Less: Quick Answer

Use fewer with countable nouns.

Use less with uncountable nouns.

Examples

• Fewer students came to class today.
• I drank less water yesterday.
• We need fewer meetings.
• She has less patience than before.

A simple memory trick is:

Count it? Use fewer. Measure it? Use less.

The Origin / Background of Fewer or Less

The words fewer and less have existed in English for hundreds of years.

Originally, people often used less with both countable and uncountable nouns. Writers such as Shakespeare even did this. Later, grammar experts suggested a clearer rule.

Around the late 1700s, grammarian Robert Baker recommended using:

• Fewer for things you count.
• Less for things you measure.

People liked this idea because it made writing more precise.

Today, this rule is taught in schools around the world. Still, everyday speech often breaks the rule. That is why phrases like “10 items or less” are still common, even though many editors prefer “10 items or fewer.”

Fewer or Less Explained: Key Differences

The biggest difference is whether the noun can be counted.

Term	Meaning	When to Use	Region/Context
Fewer	Smaller number of countable things	Books, people, cars, apples	Standard English worldwide
Less	Smaller amount of something not counted	Water, money, sugar, time	Standard English worldwide

Countable Nouns → Use Fewer

You can count them one by one.

Examples:

• fewer chairs
• fewer emails
• fewer children
• fewer mistakes

Uncountable Nouns → Use Less

These are measured rather than counted.

Examples:

• less water
• less milk
• less information
• less stress

Common Exceptions

English has a few exceptions.

We usually say:

• less than 10 minutes
• less than 20 miles
• less than $50

Even though minutes, miles, and dollars are countable, English treats measurements differently.

Which Version Should You Use?

Different situations call for different choices.

For Students

Use the grammar rule.

Choose fewer for countable nouns and less for uncountable nouns. This is what teachers and exams expect.

For Professional Writers

Always follow the standard rule.

Editors, publishers, and businesses prefer correct grammar because it sounds polished.

For Everyday Conversation

People often say less when they mean fewer.

Most listeners will understand you. However, using the correct word makes your English stronger.

For Global English

Follow the traditional grammar rule whenever possible.

It is accepted in American English, British English, Canadian English, Australian English, and many other varieties.

Common Mistakes with Fewer or Less

These mistakes appear everywhere.

Mistake	Correct Version	Why
Less people	Fewer people	People can be counted.
Less books	Fewer books	Books are countable.
Fewer water	Less water	Water is uncountable.
Less apples	Fewer apples	Apples are counted individually.
Fewer patience	Less patience	Patience cannot be counted.

Why Do People Make These Mistakes?

• They hear incorrect examples every day.
• Some signs and advertisements use less.
• Spoken English often ignores grammar rules.
• The words sound similar.

Remember the simple question:

Can I count it?

If yes, choose fewer.

If no, choose less.
