Then vs Than: Difference, Usage, and Examples

Then vs than is a common mix-up because the words look almost the same and often sound alike in fast speech.

The correct choice is simple once you know the job each word does. Then points to time, order, result, or the next step. Than is used for comparison.

Use then when you mean “at that time,” “next,” or “in that case.” Use than when you compare one thing with another.

Quick Answer

Use then for time or sequence.

Use than for comparison.

Correct: I finished work, then I went home.
Correct: This plan is cheaper than the old one.

If the sentence compares people, things, amounts, choices, or qualities, choose than. If the sentence shows when something happened or what came next, choose then.

Why People Confuse Them

People confuse then and than for three main reasons.

First, they differ by only one letter. Second, many speakers pronounce them very similarly in casual speech. Third, both words are short function words, so readers often move past them quickly.

The mistake usually happens in writing, not because the writer does not know the meaning, but because the sound in the sentence feels close enough. That is why a quick test helps: comparison needs than; time or order needs then.

Key Differences At A Glance

Context	Best Choice	Why
Comparing two things	than	It introduces the second part of a comparison.
Showing what happened next	then	It marks the next step in time or order.
Referring to a past or future time	then	It means “at that time.”
Using more, less, better, worse, taller, smaller	than	These comparison words are usually followed by than.
Using an if statement	then	It can mean “in that case.”
Saying “rather ___”	than	The phrase compares choices.
Saying “back ___”	then	The phrase points to a time in the past.

Meaning and Usage Difference

Then is mainly an adverb. It tells when something happened, what happened next, or what follows from a condition.

Examples:

I lived in Chicago back then.
Text me when you get there, and then I’ll leave.
If the office is closed, then we’ll meet online.

In these sentences, then is tied to time, order, or result.

Than is used in comparisons. It often follows words such as more, less, better, worse, older, younger, faster, and rather.

Examples:

She is taller than her brother.
This route is faster than the highway.
I would rather call than text.

In these sentences, than introduces the thing being compared.

A useful memory trick: then and when both have e. If the idea answers “when?” then is probably right.

Tone, Context, and Formality

There is no major formality difference between then and than. Both are standard in everyday, school, business, and formal writing.

The difference is not tone. It is function.

In casual speech, the words may sound close. In careful writing, the spelling matters because the wrong choice can change the meaning or make the sentence look careless.

Correct in a work email: We’ll review the draft, then send it to the client.
Correct in a work email: This option costs less than the first one.

The pronunciation is worth noting only because it causes confusion. In careful speech, then usually has the vowel sound in “pen.” Than may sound like “than” with a short “a,” but in fast American speech it is often reduced and can sound very close to then.

Which One Should You Use?

Choose then when the sentence is about time.

Use it for:

• something that happened at a certain time
• the next step in a series
• a result after “if”
• phrases like back then, since then, until then, and now and then

Choose than when the sentence compares.

Use it for:

• bigger than
• smaller than
• more than
• less than
• better than
• worse than
• rather than
• other than

Compact comparison:

• then = time, order, result
• than = comparison
• then often answers “when?” or “what next?”
• than often follows a comparison word
• then fits “after that”
• than fits “compared with”

When One Choice Sounds Wrong

Use than after comparison words.

Wrong: This laptop is faster then mine.
Correct: This laptop is faster than mine.

Wrong: We need more time then we expected.
Correct: We need more time than we expected.

Use then when showing the next step.

Wrong: Log in, than click Settings.
Correct: Log in, then click Settings.

Wrong: I was younger than.
Correct: I was younger then.

That last pair shows why meaning matters. Younger than needs something to compare with. Younger then can mean younger at that time, though the full sentence should make the time clear.
