If you often pause over than vs then, you are not alone. These two words look and sound similar, but they have different meanings and grammatical jobs.

The simplest rule is:

Than is mainly used for comparisons.
Then is mainly used for time, sequence, or consequence.

For example:

My car is faster than yours.
We ate dinner, then watched a movie.
If you finish your work, then you can leave.

The confusion happens because than and then are only one letter apart, and their pronunciation can be similar in some varieties of English. However, choosing the correct word becomes much easier once you understand what each one does.

This guide explains than vs then, including their meanings, grammar, pronunciation, history, common expressions, mistakes, formal and informal usage, and practical examples for everyday, academic, business, technical, and professional writing.

Quick Answer: Than vs Then

Word	Main Function	Basic Meaning	Example

Easy memory trick

Think:

Than = comparison

Then = time or next

If you are comparing two things, choose than.

If you are describing what happens next, choose then.

It commonly appears after comparative words such as:

better
bigger
smaller
faster
slower

fewer
rather
sooner

Examples

This book is better than the other one.

For example:

This laptop is lighter than my old one.

The comparison is between this laptop and my old one.

What Does “Then” Mean?

It can mean:

At that time
After that
Next
In that case
As a consequence

Examples

At that time:

The exact meaning depends on the sentence.

Than vs Then: The Key Difference

The easiest way to understand than vs then is to look at their purpose.

Use “than” for comparison

My new phone is cheaper than my old phone.

You are comparing two phones.

Use “then” for sequence

I bought a new phone and then transferred my data.

You are describing what happened next.

Use “then” for a condition or result

If you have finished, then you can leave.

Here, then means something like in that case.

Than vs Then Comparison Table

Feature	Than	Then
Main idea	Comparison	Time, sequence, or result
Common question	“Compared with what?”	“What happened next?”
Common position	After comparative words	Before or after an action
Meaning	Compared with	At that time, next, afterward, in that case
Example	Better than expected	Finish this then call me
Comparative adjective	Yes	No
Time reference	Usually no	Yes
Conditional statements	No	Yes

A useful test is to replace the word mentally.

If you can replace it with compared with, use than.

If you can replace it with next, afterward, at that time, or in that case, use then.

When Should You Use “Than”?

Use than when one person, object, action, or amount is being compared with another.

Comparisons With Adjectives

When Should You Use “Then”?

Use then when talking about time, order, or a result.

“Then” Means “Next”

First, read the instructions. Then, answer the questions.

Here, then tells the reader what happens next.

More examples:

Why Do People Confuse Than and Then?

The confusion between than and then has several causes.

They look almost identical

The only spelling difference is the letter a versus e.

than
then

That small difference is easy to miss when typing quickly.

They can sound similar

In some accents, unstressed vowels may become less distinct. This can make the words harder to distinguish in casual speech.

However, in careful standard American pronunciation, they are generally distinguished:

than: /ðæn/
then: /ðɛn/

The th sound is the voiced sound heard in words such as this and that.

Autocorrect does not always help

Both than and then are correctly spelled English words. A spell checker may therefore accept the wrong one.

For example:

This one is better then that one.

Every individual word is spelled correctly, but then is grammatically wrong. It should be than.

This is an example of a contextual spelling error, not a simple spelling mistake.

Than vs Then Pronunciation

In standard American English, the two words are commonly pronounced differently.

Than

Than usually sounds like:

“than”

Its vowel is similar to the vowel in cat for many American English speakers.

Then

Then usually has a vowel similar to the vowel in bed.

The distinction can become less noticeable in fast or casual speech, especially when than is unstressed.

For writers, however, pronunciation should never determine which spelling you use.

Meaning and grammatical function determine the correct word.

Is “Than” a Preposition or a Conjunction?

This is a more advanced grammar question.

Than can function in different ways depending on the sentence structure.

As a conjunction

She is taller than I am.

Here, than introduces a clause.

As a preposition

She is taller than me.

In modern English, this construction is extremely common, especially in everyday American English.

There has been long-standing debate about whether expressions such as than me or than I are more grammatically appropriate. The answer often depends on the sentence structure, style, and level of formality.

For formal writing, you may choose a complete clause when clarity matters:

She is taller than I am.

In casual conversation:

She’s taller than me.

Both are widely understood.

Is “Then” an Adverb?

Yes. Then is most commonly used as an adverb.

It can modify an action by showing when or in what order something happens.

We ate then.

Then we left.

It can also indicate a logical consequence:

If that’s true, then we need to reconsider the plan.

Because then has several related meanings, context determines its exact function.

Common Expressions With “Than”

Many familiar English phrases use than because they involve comparison.

Common expressions

better than
more than
less than
rather than
other than
sooner than
later than
bigger than
easier than
harder than
different than

Examples

This is more than enough.

She chose tea rather than coffee.

The answer was different than I expected.

He arrived later than usual.

Common Expressions With “Then”

Then appears frequently in expressions related to time and sequence.

Common expressions

back then
since then
until then
by then
from then on
just then
now and then
every now and then
and then
then again
if-then

Examples

Back then, we didn’t have smartphones.

I haven’t seen her since then.

By then, the store had closed.

We decided to move from then on.

I still visit every now and then.

“Rather Than” vs “Rather Then”

The correct expression is:

rather than

Not:

~~rather then~~

Rather than introduces a preference or alternative.

Examples:

I stayed home rather than go out.
She chose tea rather than coffee.
We should repair the machine rather than replace it.
He listened rather than argue.

This is one of the most common than vs then spelling mistakes.

“Better Than” vs “Better Then”

The correct expression is:

better than

Not:

~~better then~~

Why?

Because better is a comparative adjective. It requires than when introducing the thing being compared.

Correct

This option is better than the first one.

Incorrect

This option is better then the first one.

A useful rule is:

Comparative word + than

Examples:

faster than
cheaper than
stronger than
more useful than
less expensive than

“If Then” vs “If Than”

The correct combination is:

if…then

Not:

~~if…than~~

Example:

If it rains, then we will stay inside.

Why?

Because then introduces the result or consequence of the condition.

This structure is common in:

everyday conversation
academic writing
programming logic
mathematics
business analysis
technical instructions

Technical example

If the value is zero, then the function returns an error.

In programming and formal logic, if-then describes a conditional relationship.

Than vs Then in Academic Writing

Academic writing requires careful distinction between the two words.

Correct

The second method was more effective than the first.

The researchers collected the data and then analyzed the results.

The sample was smaller than expected.

The experiment was repeated, and then the results were recorded.

A useful editing technique is to check every occurrence of than and then separately.

Ask:

Is this word comparing two things?

If yes, choose than.

Is it describing time, sequence, or a consequence?

If yes, choose then.

Than vs Then in Business Writing

Business communication often uses both words.

Than for comparisons

Our costs were lower than last quarter.

The new system is more efficient than the old one.

Sales were higher than projected.

Then for sequence

Review the proposal and then send it to the client.

First, approve the budget. Then, contact the supplier.

Using the wrong word can make professional writing look careless even when the meaning remains obvious.

Than vs Then in Technical Writing

Technical instructions frequently use then because procedures involve sequences.

For example:

Connect the cable. Then restart the device.

Comparisons, however, require than:

The new processor is faster than the previous model.

Technical writers should be especially careful because than and then can appear close together in complex explanations.

Than vs Then in Sports Writing

Sports reporting commonly uses than for statistics and comparisons.

The team scored more points than its opponent.

The player ran faster than expected.

Then is used to describe game sequence:

The team scored first and then defended its lead.

Formal vs Informal Usage

There is no major regional difference in the basic distinction between than and then.

American and British English both use:

than for comparison
then for time, sequence, and consequence

The larger differences involve surrounding constructions.

For example, American English commonly accepts:

Different than what I expected.

British English traditionally favors:

Different from what I expected.

However, different than is well established in American usage.

This does not change the central rule:

than and then are not interchangeable.

Common Than vs Then Mistakes

Here are some of the mistakes you are most likely to encounter.

Mistake: “Better then”

Incorrect:

My new job is better then my old one.

Correct:

My new job is better than my old one.

Mistake: “First than”

Incorrect:

First finish your work, than call me.

Correct:

First finish your work, then call me.

Here, then means after that.

Mistake: “Rather then”

Incorrect:

I’d rather walk then drive.

Correct:

I’d rather walk than drive.

Mistake: “If than”

Incorrect:

If you’re ready, than we can start.

Correct:

If you’re ready, then we can start.

Mistake: “More then”

Incorrect:

The repair cost more then expected.

Correct:

The repair cost more than expected.

Awkward vs Natural Examples

Sometimes a sentence is technically understandable but can be improved.

Awkward

I was younger than then.

More natural

I was younger back then.

Here, back then clearly refers to a past period.

Awkward

First we went to the store than we went home.

Natural

First we went to the store, then we went home.

Awkward

This method works better then the old method.

Natural

This method works better than the old method.

How to Remember Than vs Then

Here are several simple memory tricks.

Remember “A” for comparison

The word than contains an A.

Think:

A = compare

For example:

Bigger than
Better than
Faster than

This is not a grammatical rule, but it is a useful memory device.

Remember “E” for event

Then contains an E.

Think:

E = event or sequence

For example:

First this happens, then that happens.

Again, it is simply a mnemonic.

Ask one question

When unsure, ask:

Am I comparing?

If yes → than

If not, ask:

Am I talking about what happens next, when something happened, or what follows from a condition?

If yes → then

Antonyms of Than and Then

However, their meanings can be contrasted with related concepts.

For than, comparison may involve:

more vs less
greater vs smaller
better vs worse
higher vs lower

For then, time can contrast with:

now
before
earlier
currently

For example:

I lived there then, but I live here now.

The History of Than and Then

The history of these words helps explain why they look so similar.

Both than and then are historically related to old Germanic words expressing ideas involving time, comparison, and sequence. Their forms developed over centuries as English changed.

In Old and Middle English, spellings were far less standardized than they are today. Words related to then and than appeared in several forms, and their meanings were historically connected.

Over time, English increasingly developed a distinction between:

than for comparison
then for time and sequence

Modern spelling eventually settled on the forms we use today.

This history is one reason the words can seem strangely similar despite having different grammatical functions.

Can “Than” and “Then” Ever Be Interchanged?

In standard modern English, no.

They have different functions.

Comparison

He is older than me.

Not:

He is older then me.

Sequence

He ate dinner and then left.

Not:

He ate dinner and than left.

Changing the word can create a grammatical error even if the intended meaning is obvious.
