Quick Answer
The short answer is simple:
✅ Hundreds of thousands is the correct and natural expression in standard English.
❌ Hundred thousands is generally considered incorrect in modern English usage.
For example:
- Hundreds of thousands of people attended the festival.
- The video received hundreds of thousands of views.
- Hundreds of thousands of dollars were donated.
These examples sound natural because English uses the structure:
Plural number word + of + noun
When discussing an approximate large quantity.
By contrast:
- Hundred thousands of people attended. ❌
This construction sounds awkward and ungrammatical to most native speakers.
Understanding the Difference at a Glance
| Expression | Correct? | Meaning |
| Hundred thousands | ❌ Usually incorrect | Nonstandard construction |
| Hundreds of thousands | ✅ Correct | A large but unspecified number between roughly 200,000 and 999,999 |
| One hundred thousand | ✅ Correct | Exactly 100,000 |
| Five hundred thousand | ✅ Correct | Exactly 500,000 |
The key difference is whether you’re expressing an exact quantity or an approximate quantity.
What Does “Hundreds of Thousands” Mean?
The phrase hundreds of thousands refers to a very large number, usually somewhere between 200,000 and 999,999.
It doesn’t specify an exact figure. Instead, it communicates scale.
For example:
- Hundreds of thousands of visitors travel to the park annually.
- Hundreds of thousands of books were sold.
- Hundreds of thousands of fans watched the livestream.
In each sentence, the exact number isn’t important. The emphasis is on the fact that the amount is very large.
Why Writers Use It
Sometimes exact numbers aren’t available.
Other times, the precise figure doesn’t matter.
Imagine saying:
487,263 people attended.
That’s accurate.
However, in casual conversation or general writing, you might simply say:
Hundreds of thousands attended.
The message remains clear while sounding more natural.
Why “Hundred Thousands” Is Usually Incorrect
To understand why hundred thousands sounds wrong, you need to understand how English forms large numbers.
English treats large-number words differently depending on whether the quantity is exact or approximate.
Consider these examples:
- One hundred thousand
- Two hundred thousand
- Three hundred thousand
These are exact numbers.
Notice that hundred remains singular.
The same rule applies to:
- One hundred
- Two hundred
- Five hundred
English does not usually pluralize “hundred” after a specific number.
You wouldn’t write:
- Two hundreds ❌
- Five hundreds ❌
Instead:
- Two hundred ✓
- Five hundred ✓
The same pattern extends to larger numbers.
Therefore:
- Three hundred thousand ✓
- Three hundred thousands ❌
The Missing Word That Changes Everything
When expressing an approximate quantity, English introduces a different structure.
Instead of:
Hundred thousands
English uses:
Hundreds of thousands
The word of creates a grammatical bridge between the pluralized quantity and the larger unit.
Compare:
| Incorrect | Correct |
| Hundred thousands | Hundreds of thousands |
| Thousand millions | Thousands of millions |
| Million billions | Millions of billions |
The preposition of is essential.
Without it, the phrase sounds incomplete.
The Grammar Rule Behind Large Number Expressions
Once you understand this rule, you’ll rarely make mistakes with large numbers again.
The pattern works like this:
Exact Quantities
When a specific number comes first, use the singular form.
Formula
Number + hundred/thousand/million/billion
Examples
- One hundred thousand
- Four hundred thousand
- Seven hundred thousand
- Ten million
- Fifty billion
Notice something interesting:
Even though the quantity is plural, the word itself remains singular.
You say:
- Five hundred
- Six thousand
- Eight million
Not:
- Five hundreds ❌
- Six thousands ❌
- Eight millions ❌
Approximate Quantities
When discussing a large but uncertain amount, pluralize the number word and add of.
Formula
Plural number word + of + noun
Examples
- Hundreds of thousands
- Thousands of people
- Millions of dollars
- Billions of stars
This structure signals approximation rather than precision.
Hundreds of Thousands vs. Hundred Thousand
Many learners confuse these expressions because both involve similar words.
Let’s compare them directly.

When to Use “Hundred Thousand”

Examples:

This construction emphasizes magnitude rather than accuracy.
Similar Expressions That Follow the Same Rule

English uses the same pattern for many numerical expressions.
| Exact Quantity | Approximate Quantity |

Understanding one pattern helps you master all of them.

Population and Migration
Governments often report that hundreds of thousands of people move between regions every year.
For example:
- Hundreds of thousands relocate for work.

The exact number changes each year, making approximation practical.
Social Media Growth
Content creators frequently use the phrase when discussing audience size.
Examples:
- The post received hundreds of thousands of likes.

- Hundreds of thousands of comments were posted.
This wording feels more natural than citing exact statistics every time.
Natural Disasters
News organizations commonly report:

Business and Sales
Companies often announce:

These statements highlight success without overwhelming readers with exact figures.
A Simple Case Study: Why Approximate Numbers Matter
Imagine two headlines:
Headline A
468,294 People Attend Annual Festival
Headline B
Hundreds of Thousands Attend Annual Festival
Both communicate essentially the same idea.
However, the second headline is:
- Easier to read
- Easier to remember
- Faster to understand
This is why journalists, marketers, and professional writers frequently use approximate numerical expressions.
They communicate impact instantly.
Common Mistakes and How to Avoid Them
Even experienced writers occasionally make errors with large-number expressions.
Let’s examine the most common ones.
Mistake: Writing “Hundred Thousands”
Incorrect:
Hundred thousands of people attended.
Correct:
Hundreds of thousands of people attended.
Why?
English requires both:
- The plural form (hundreds)
- The preposition (of)
Without them, the phrase sounds unnatural.
Mistake: Adding “Of” to Exact Numbers
Incorrect:
Three hundred of thousand people attended.
Correct:
Three hundred thousand people attended.
Exact numbers don’t require “of.”
Mistake: Pluralizing Exact Numbers
Incorrect:
Five hundreds thousand dollars
Correct:
Five hundred thousand dollars
After a specific number, “hundred” remains singular.
