Then vs Than: Difference, Meaning, and Examples

Then and than differ by only one letter, but they do very different jobs in a sentence.

Then is mainly connected with time, sequence, or what happens as a result.

Than is mainly used for comparisons.

That basic distinction works well, but a few common constructions are worth understanding more carefully.

Then vs Than: The Main Difference

The simplest distinction is:

If the sentence is about when something happened, what happened next, or what follows from a condition, you probably need then.

If the sentence is comparing things, amounts, qualities, or actions, you probably need than.

When to Use Then

Then has several related uses. They are not all about clock time, but they share the idea of a point in time, a sequence, or a consequence.

Then Meaning “At That Time”

Use then to refer to a particular time in the past or future.

I was working in Singapore then.

The neighborhood was much quieter back then.

By then, the research team had already collected enough data.

In these examples, then points to a time already understood from the context.

Then Meaning “Next” or “After That”

Then can show the next step in a sequence.

Review the figures first, then update the forecast.

The lights dimmed, then the presentation began.

Marcus finished the client call and then returned to the budget report.

Here, then helps show the order in which events happen.

Then Meaning “In That Case” or “As a Result”

Then can also introduce what follows from a condition, fact, or decision.

If the roads are still closed, then we will postpone the delivery.

If that is your final decision, then there is nothing more to discuss.

In this use, then means something close to in that case or as a consequence.

So then is not limited to chronological time. It can also connect a condition with what follows from it.

When to Use Than

Use than when making a comparison.

The northern route is shorter than the coastal road.

Revenue increased faster than analysts expected.

The new policy affects more departments than the previous one.

Than often follows comparative words such as:

taller than

more expensive than

less complicated than

faster than

better than

worse than

It can compare people, objects, quantities, actions, or entire situations.

Olivia handles unexpected questions more calmly than I do.

The renovation cost less than the original estimate.

Working from the regional office takes longer than working from home.

In these constructions, than introduces the second side of the comparison.

Rather Than, Other Than, More Than, and Less Than

Than also appears in several common expressions.

Rather Than

Rather than introduces an alternative or preference.

She chose to revise the proposal rather than withdraw it.

We decided to repair the existing equipment rather than replace it.

Other Than

Other than often means except for or apart from.

No one other than the project manager had access to the final report.

Other than a minor delay, the launch went as planned.

More Than and Less Than

These expressions compare quantities, amounts, or degrees.

More than fifty applications arrived before noon.

The repair took less than an hour.

The final cost was more than we had originally budgeted.

No Sooner … Than

One common construction does not fit neatly into the simple idea that than only introduces an ordinary comparison.

The standard expression is:

no sooner … than

It shows that one event happened immediately after another.

No sooner had the meeting ended than reporters began asking questions.

We had no sooner submitted the proposal than the client requested a revision.

Even though the meaning involves sequence in time, than is the correct word in this fixed construction.

Not:

no sooner … then

This is worth remembering as a pattern rather than trying to force it into the usual time-versus-comparison shortcut.

Than Me or Than I Am?

Both forms can be standard, but the grammar is different.

She is taller than me.

Here, than can function like a preposition, with me as its object.

She is taller than I am.

Here, than introduces a clause. I is the subject of am.

The second version can sound more formal, but the first is common and standard in everyday English.

The choice can also affect clarity.

Consider:

Daniel respects Maya more than me.

This can be ambiguous.

It might mean:

Daniel respects Maya more than he respects me.

Or it might mean:

Daniel respects Maya more than I respect Maya.

Expanding the comparison removes the ambiguity:

Daniel respects Maya more than he respects me.

or:

Daniel respects Maya more than I do.

So the issue is not simply whether me or I is correct. The full structure and intended meaning matter.

Then and Than in the Same Sentence

Because then and than have different jobs, both can appear naturally in the same sentence.

She was more confident then than she is now.

Here:

• then means at that time;
• than introduces the comparison with the present.

Another example:

The office was much smaller then than it is today.

Seeing both words together makes the distinction especially clear. One points to time, while the other connects the comparison.

How to Choose Then or Than

Use then for:

• a point in time;
• what happens next;
• a sequence;
• what follows from a condition.

Finish the draft, then send it for review.

Use than for:

• comparisons;
• more than;
• less than;
• rather than;
• other than.

The revised draft is shorter than the original.

And remember the fixed expression:

no sooner … than

A useful memory clue is that then often relates to when, while than usually belongs with comparison.

The main distinction is simple: then points to time, sequence, or consequence; than usually connects things being compared.
