“Then” and “than” are both correct words, but they have different meanings. “Then” is an adverb used to refer to a time, sequence, or result, while “than” is a conjunction or preposition used to make comparisons.
Then or than?
These two small English words cause many writing mistakes. They look similar, sound somewhat similar, and often appear in simple sentences. However, their meanings are completely different.
The easiest way to understand them is this:
Than is used for comparison.
Then is used for time, order, or what happens next.
For example:
Ali is taller than Ahmed.
Here, two people are being compared.
Now look at this:
Ali finished his work, then he went home.
Here, then shows what happened next.
A single letter changes the meaning of the sentence. That is why learning the difference between then and than is important for students, writers, bloggers, professionals, and English learners.
The good news is that you do not need complicated grammar rules. Once you learn one simple question to ask yourself, choosing the correct word becomes much easier.
This guide explains the difference between then or than, with simple examples, memory tricks, common mistakes, exercises, and practical writing tips.
Then vs Than: The One-Question Test
When you are unsure which word to use, ask yourself:
Am I comparing two things?
If the answer is yes, use than.
She is taller than her sister.
This book is better than that one.
I would rather walk than wait.
Am I talking about time, order, or what happens next?
If the answer is yes, use then.
We ate dinner, then watched a movie.
Finish your work, then take a break.
Back then, things were different.
This simple test solves most then or than mistakes.
The Main Difference Between Then and Than
| Word | Main Use | Meaning |

| Then | Result | In that case |
| Than | Comparison | Compared with |

Quick Examples
Then:

Than:

The first sentence shows order.
The second sentence makes a comparison.
When Should You Use “Than”?
The word than is mainly used when comparing people, things, amounts, ideas, or actions.
Think of than as a comparison word.
1. Comparing People
Sara is younger than her brother.
John runs faster than me.
My teacher is taller than I expected.
In every example, one person is compared with another person or expectation.
2. Comparing Things
This phone is more expensive than my old phone.
Summer is hotter than winter.
Tea is cheaper than coffee at this restaurant.
Again, than shows a comparison.
3. Comparing Amounts

She spent less money than last month.
There are fewer students than yesterday.
Words such as these often appear with than:
- more than
- less than
- better than
- worse than
- bigger than
- smaller than
- faster than
- slower than
4. Expressing Preference
Than can also appear when showing a preference.
I would rather stay home than go out.
She prefers reading than watching television.
In natural English, the structure may change depending on the sentence, but than is commonly used when one option is compared with another.
When Should You Use “Then”?
Unlike than, the word then has several jobs.
The easiest way to remember it is to connect then with:
- Time
- Order
- Next
- Result
Then for Time
Use then when talking about a particular time.
I was living in London then.
Life was different back then.
I did not understand English very well then.
In these examples, then means:
at that time
Then for Order
This is one of the most common uses.
Use then to show what happens after something else.

She got dressed and then left the house.
We finished the meeting and then went for lunch.
You can think of then as meaning:
next
Then for a Result
Then can also show what happens as a result.
If you are tired, then take a break.
If the answer is correct, then continue.
If it rains, then we will stay inside.
In everyday English, people often leave out then:
If it rains, we will stay inside.
Both structures can work depending on the sentence.

The “Comparison or Timeline” Method
Here is another easy way to choose the correct word.
Imagine that every sentence belongs to one of two boxes.
Box 1: Comparison
Use than.
Questions to ask:
- Which one is bigger?
- Which one is better?
- Which one is faster?
- Which one has more?
- Which option do I prefer?
Examples:
She is taller than me.
Today is warmer than yesterday.
Box 2: Timeline
Use then.
Questions to ask:
- What happened next?
- When did it happen?
- What comes after this?
- What was true at that time?
Examples:
First study, then sleep.
I was younger then.
This method is simple and useful when proofreading your writing.
Then and Than in Professional Writing
Small spelling mistakes can affect how professional a document looks.
Imagine writing this in an email:
❌ Our new system is faster then the old system.
The correct sentence is:
Our new system is faster than the old system.
Now look at this:
❌ Please review the document, than send your feedback.
The correct sentence is:
Please review the document, then send your feedback.
The meanings are different.
In professional writing, take a few seconds to check if you are showing:
- A comparison → than
- A sequence → then
This simple habit can prevent a common mistake.
A Quick Proofreading Trick
Before submitting your writing, try replacing the word.
Test for “Than”
Replace it with:
compared with
Example:
My house is bigger than yours.
Becomes:
My house is bigger compared with yours.
The sentence still has a comparison meaning.
So than is correct.
Test for “Then”
Replace it with:
next
Example:
Finish your work, then relax.
Becomes:
Finish your work, next relax.
The wording may need adjustment, but the idea of sequence remains.
Another test is:
at that time
Example:
I was living in Karachi then.
Becomes:
I was living in Karachi at that time.
The meaning works.
So then is correct.
