English learners often stop when they see sentences like “Over 100 people came” and “More than 100 people came.” Both look different, so it is natural to wonder whether one is correct and the other is wrong.
The good news is that, when we are talking about a number, amount, age, price, or level, over and more than can usually express the same basic idea: a figure greater than a stated point.
There is also a second reason this topic can feel tricky. Over has many meanings that have nothing to do with numbers. It can mean above something, across something, during a period, or finished. More than has its own wider uses too. For example, “more than happy” does not simply mean a quantity greater than “happy.”
By the end, you will know when these expressions mean the same thing, when they do not, how to use them in questions and sentences, and which one sounds more natural in different situations.
You will also have simple rules and everyday examples you can use right away.
Most importantly, you will not need to memorize a long list of exceptions to make the right choice in everyday spoken and written English.
This is a useful point to learn because both expressions are common in school, work, shopping, news, conversations, signs, and online writing. Once you understand the pattern, sentences with over and more than become much easier to read and write.
What Does “More Than” Mean?
More than is used to show a quantity, number, amount, degree, or level that is greater than another figure or point. In a sentence such as “More than 20 students attended,” the speaker means that the number of students was greater than 20.
A simple pattern is:
more than + number/amount
Examples include:
- more than 10 people
- more than $50
- more than three hours
- more than 90 percent
- more than 18 years old
When should you use “more than”?
Use more than when you compare a quantity or show that something exceeds a stated amount.
Examples:
- “I have more than 100 photos on my phone.”
- “The trip took more than five hours.”
- “She earns more than $2,000 a month.”
It also works without a number: “This bag costs more than I expected.” Here, the speaker is comparing the actual price with an expectation.
Grammar rule for “more than”
The phrase more than normally comes before the number, amount, or comparison it introduces.
Pattern: subject + verb + more than + number/amount
Example: “More than 500 customers visited the store.”
You can also use it at the beginning of a sentence:
“More than 500 customers visited the store.”
There is no special verb form after more than. The verb agrees with the real subject of the sentence.
For example:
“More than 10 students are waiting outside.”
Here, students is plural, so are is correct.
Examples with “more than”
- More than 30 people attended the meeting.
- She has lived here for more than ten years.
- The jacket costs more than $100.
- More than half of the class finished the test.
- We waited for more than an hour.
- The video has received more than one million views.
A common learner confusion is believing that more than is only for countable things. It is not. You can use it with people, money, time, distance, percentages, and many other measurements.
The key idea is simple: the value or amount is greater than the stated point.
What Does “Over” Mean?
Over is a very flexible English word. It can work as a preposition, adverb, adjective, or part of a larger word. One of its common meanings is more than a particular number or amount. Cambridge Dictionary gives examples such as “over 100 people” and “over 10 kilos,” showing that this numerical use is standard English.
A simple numerical pattern is:
over + number/amount
Examples:
- over 10 people
- over $100
- over 18
- over 5 kilometers
- over 90 percent
When should you use “over”?
Use over when a number, age, amount, or level is above a stated point.
Examples:
- “Over 200 people came.”
- “This phone costs over $500.”
- “Children over 12 can enter.”
- “The package weighs over five kilos.”
It can also show that a limit was exceeded, as in “The project is over budget.”
Grammar rule for “over”
When over means “more than,” it normally comes directly before the number or amount.
Pattern: subject + verb + over + number/amount
Example:
“The hotel has over 300 rooms.”
You can also use over before an age:
“Guests over 18 must show ID.”
And you can use it in expressions such as:
- 18 and over
- $20 and over
- 100 and over
These mean “18 or older,” “$20 or more,” and “100 or more.” Cambridge Dictionary records this “and over” use as well.
Examples with “over”
- Over 40 students signed up for the class.
- The repair cost over $200.
- She is over 21 years old.
- We drove over 300 kilometers today.
- The building is over 100 years old.
- People aged 65 and over can receive the discount.
A common confusion is believing that over is always less formal than more than. That is too simple. Both are accepted for quantities, and the Chicago Manual of Style says they are interchangeable for that use, while noting that some traditional “sticklers” may still object.
Difference Between More Than and Over
Before numbers or amounts, the main difference is usually style and wording, not basic meaning.
“More than 500 people attended.”
“Over 500 people attended.”
Both normally mean that attendance was greater than 500.
Comparison table
| Point | More than | Over |
|---|---|---|
| Basic numerical meaning | Greater than a stated number or amount | Greater than a stated number or amount |
| Example | More than 100 people came. | Over 100 people came. |
| Used with money | Yes | Yes |
| Used with age | Yes | Yes |
| Used with time | Yes | Yes |
| Used with percentages | Yes | Yes |
| Used in questions | Yes | Yes |
| Other major meanings | Comparison, degree, addition | Above, across, during, finished, and more |
| Common feel | Clear and explicit | Short and natural |
Usage difference
The key difference is that more than is mainly a comparison phrase, while over has many meanings. With physical nouns, over may mean “above” or “across.” Cambridge lists these meanings separately from its numerical use.
Compare:
- “More than 20 people came.”
- “Over 20 people came.”
Both are about quantity.
Now compare:
- “The lamp is over the table.”
- “The plane flew over the city.”
- “We climbed over the wall.”
These sentences are not about quantity at all.
So context decides the meaning of over.
Grammar logic
Both forms can introduce a quantity:
- more than 100 people
- over 100 people
The important part is the relationship between the number and the quantity. In either sentence, the actual number is above 100.
Consider:
“More than 1,000 people watched the game.”
“Over 1,000 people watched the game.”
In ordinary modern English, these sentences communicate the same basic numerical fact.
Sentence structure difference
The most common structures are:
More than + number/amount + noun
- more than 50 books
- more than $1,000
- more than three hours
Over + number/amount + noun
- over 50 books
- over $1,000
- over three hours
In noun phrases, both can modify the noun that follows:
“More than 50 students joined.”
“Over 50 students joined.”
Meaning comparison
There are situations where the two expressions cannot simply replace each other.
For example:
“The picture is over the sofa.”
You cannot replace over with more than because the sentence is about position.
Likewise:
“She is more than happy to help.”
Here, more than means something stronger than a simple numerical comparison; it can mean “very” or “extremely” in certain expressions. Cambridge Dictionary lists this idiomatic use, such as “more than happy” and “more than likely.”
So the useful rule is:
For quantities above a number or limit, they are usually interchangeable. Outside that meaning, they may be completely different.
Grammar Rules You Must Remember
Rule 1: For numbers and amounts, both can mean “greater than”
Use either expression before a numerical quantity when you want to show that the amount is above the stated figure.
Examples:
- More than 100 people came.
- Over 100 people came.
- The box weighs more than 10 kilos.
- The box weighs over 10 kilos.
Chicago’s current online guidance says the two are interchangeable for quantities, reflecting modern usage.
Rule 2: “Over” has many non-numerical meanings
Do not assume that over always means “more than.”
For example:
- The bird flew over the house.
- Put the blanket over the baby.
- We talked over lunch.
- The movie is over.
Here, over means something different in each context. Cambridge lists uses involving position, movement, time, and completion, among others.
Rule 3: “More than” can introduce comparisons and degrees
More than is not limited to numbers.
Examples:
- This is more than I expected.
- She needs more than a quick answer.
- He was more than happy to help.
- The problem is more than we can handle.
In these sentences, replacing the phrase with over would either change the meaning or produce an incorrect sentence.
Rule 4: Use “and over” for minimum ages or amounts
Expressions such as 18 and over mean “18 or older,” while $20 and over means “$20 or more.”
Examples:
- This event is for people aged 18 and over.
- The discount is available for purchases of $50 and over.
- Tickets are free for children five and under and discounted for those six and over.
This is a common structure on signs, notices, websites, and forms.
Common Mistakes Students Make
Learners often make mistakes because they try to create one strict rule: “Always say more than” or “Always say over.” English is more flexible.
Mistake 1: Thinking “over” is wrong before a number
Wrong idea:
“Over 100 people came” is incorrect.
That is not true. Modern English accepts over 100 as a normal way to express a quantity greater than 100.
Correct:
“Over 100 people came.”
Also correct:
“More than 100 people came.”
Mistake 2: Replacing every “over” with “more than”
This creates errors when over has a different meaning.
Incorrect:
“The helicopter flew more than the building.”
The intended meaning is probably about physical movement above the building.
Correct:
“The helicopter flew over the building.”
Mistake 3: Replacing “more than” with “over” in idioms
Incorrect:
“I am over happy to help.”
Correct:
“I am more than happy to help.”
The expression more than happy is a natural idiom meaning very happy or completely willing.
Mistake 4: Confusing “more than 18” with “18 and over”
These can be close in everyday meaning, but the wording matters.
“People over 18” commonly means people older than 18.
“People aged 18 and over” includes people who are 18.
So if the exact boundary matters, use the wording that clearly states the rule.
Easy correction tip
When you see over, ask:
“Is this about a number or amount?”
If yes, more than is often possible.
If the answer is no, check for another meaning such as “above,” “across,” “during,” or “finished.”
That one question solves many mistakes.
Easy Trick to Remember the Difference
Think “number” vs. “position”
When over comes with a number, it can often mean more than:
- over 50 = more than 50
- over $100 = more than $100
When it comes with a place or object, it may mean above or across:
- over the table = above the table
- over the bridge = across or beyond the bridge
Number? Over can mean more than.
Place? Over may mean above or across.
Another useful test is substitution. Replace over with more than.
“Over 500 people attended.”
→ “More than 500 people attended.”
The numerical meaning stays the same.
But “The painting is over the sofa” cannot use more than, because over describes position.
This is a practical test for beginners because it uses meaning rather than memorization.
Daily Life Examples
Here are eight natural examples from everyday English.
1. School
A: “How many students are in the new class?”
B: “Over 40.”
“More than 40” means the same thing.
2. Age
A: “Can teenagers join this event?”
B: “Yes, but they must be over 16.”
If 16-year-olds are included, say “16 and over.”
3. Shopping
A: “How much did your phone cost?”
B: “It was over $500.”
“More than $500” is also correct.
4. Time
A: “How long was the movie?”
B: “More than two hours.”
“Over two hours” works too.
5. Work
A: “How many emails did you receive?”
B: “More than 100.”
“Over 100” is equally natural.
6. Travel
A: “How far did you drive?”
B: “Over 300 kilometers.”
The distance was greater than 300 kilometers.
7. Crowd
A: “Was the concert busy?”
B: “Yes. Over 5,000 people came.”
The number was greater than 5,000.
8. Price
A: “Do you have a cheaper option?”
B: “The first one is under $100, but the better one is over $150.”
Here, over means above that price.
Notice how quickly context changes the job of over. In “over 5,000 people,” it expresses quantity. In “over the door,” it expresses position. In “the meeting is over,” it means finished.

FAQs
What is the difference between “more than” and “over”?
When talking about a number, amount, age, or level, they often have the same meaning. “More than 100” and “over 100” both mean a figure greater than 100. The bigger difference appears when over is used for other meanings such as position or movement.
Can we use “over” in questions?
Yes. You can say, “Did over 50 people come?” You can also ask, “Did more than 50 people come?” Both are normal when asking whether the number exceeded 50.
Is “over” formal or informal?
Over is used in both everyday and formal English when it means “more than.” It is common in news reports, business writing, signs, and conversation. Some older style traditions preferred more than with numbers, but modern guidance accepts both.
Is “more than” always better than “over”?
No. Neither word is always better. For a numerical quantity, both usually work. However, more than is necessary in some comparison or idiomatic expressions, while over is necessary when you mean “above” or “across” something.
Can “more than” and “over” be used with money?
Yes. Both are common.
- The laptop costs more than $800.
- The laptop costs over $800.
Both tell the listener that the price is greater than $800.
Does “over 18” include people who are exactly 18?
Usually, over 18 means older than 18, so it does not normally include someone who is exactly 18. When you want to include 18, say 18 and over or aged 18 and over. This distinction is important on official rules and signs.
Conclusion
The difference between more than and over becomes much easier once you focus on meaning instead of memorizing one rigid rule. When you are talking about a number, amount, age, price, distance, time, or level above a stated point, the two expressions are usually interchangeable. You can say “more than 100 people” or “over 100 people,” and the basic meaning stays the same.
The important exception is that over has many other meanings. It can mean above, across, during a period, or finished. More than also has wider uses, especially in comparisons and expressions such as “more than happy.”
A good habit is to look at the context before choosing the word. Ask yourself whether you are talking about a quantity or something else. Then practice with short, everyday sentences. Once you start noticing these patterns in real English, the choice will feel natural rather than confusing.
