Then vs Than: Understanding the Difference

By the Dictionary Wiki Editorial Team · Published February 19, 2024 · Updated April 7, 2024 · 1,317 words · Word Comparisons

Only one letter separates then from than, but that small spelling change does a lot of work. One word helps you place events in time or order. The other helps you compare people, things, choices, amounts, or qualities. That is why writers mix them up so often, just as they do with pairs like there/their/they're and your/you're.

Here is the dependable split: use then when the idea is time, sequence, or consequence. Use than when the idea is comparison. Once you learn to spot those two jobs, the then vs than choice becomes much easier.

The Fast Rule

Then = time (when, next, at that time).
Than = comparison (more/less, bigger/smaller, rather).

Choose “then” for timing, order, or what follows. Choose “than” when one thing is being measured against another. That one distinction answers almost every then vs than question you are likely to face.

How “Then” Works with Time

Then is usually an adverb, and its meanings are tied to time or order. It can point to a moment in the past or future, show the next step, or introduce a result that follows from a condition. Different uses, same basic idea: something is happening at a time or after something else.

“Then” for a Specific Time

“I worked at the bookstore then.” (At that time, I worked there.)
“Prices were lower back then.” (During that earlier period.)
“Send me the final numbers by then.” (By that future point.)
“He was then the only freshman on the varsity team.” (At that moment.)

“Then” for What Comes Next

“Pack your bag, and then call a taxi.” (After packing.)
“Open the app. Then, tap the blue button.” (The next step.)
“They signed the lease, then started painting the apartment.” (After signing.)
“Wash your hands, then help set the table.” (After washing.)

“Then” for a Result or Consequence

“If the road is closed, then take the bridge.” (In that case.)
“If everyone is ready, then we can begin.” (In that situation.)
“If the soup is too salty, then add a little water.” (As a result.)

“Then” for an Added Point

“We need to pay for the room, and then there are cleaning fees.” (Added to that.)
“The hike was steep and then some.” (Even more than that.)

How “Than” Works with Comparisons

Than is used when a sentence compares. It may compare size, speed, value, number, quality, preference, or expectation. If the sentence is setting one thing beside another, “than” is the word you want. In a then vs than choice, comparison always points to “than.”

Using “Than” to Compare

“My backpack is heavier than yours.” (Comparing weight.)
“This route is faster than the highway.” (Comparing speed.)
“She saved more than we expected.” (Comparing amount.)
“The second draft is clearer than the first.” (Comparing quality.)
“The meeting lasted longer than planned.” (Comparing length to a plan.)
“A quiet apology can matter more than a grand speech.” (Comparing effect.)
“Fewer than twenty tickets remain.” (Comparing a number to twenty.)
“He would rather cook than order takeout.” (Comparing preferences.)

Words such as more, less, better, worse, larger, smaller, higher, lower, quicker, slower, and rather often signal that “than” is coming. You may not always see one of those exact words, but if the sentence contains a comparison or a preference, use “than.”

“Than” with “Rather” and “Other”

“I’d rather email than call.” (Preference comparison.)
“They decided to save the money rather than spend it.” (Choosing one option over another.)
“Someone other than Maria locked the door.” (Exclusion comparison.)

Easy Ways to Remember

Then = timE. Both “then” and “time” have the letter E. When the sentence is about when something happens, think thEn.

Than = compArison. Both “than” and “comparison” contain the letter A. When you compare, choose thAn.

Try “next” or “afterward.” If “next” or “afterward” fits the sentence, “then” is probably right. “We ate, next we left” sounds like the same idea as “We ate, then we left.”

Ask the comparison question. Are two things, actions, amounts, or choices being compared? If yes, write “than.” If not, check whether “then” makes sense instead.

Errors That Show Up Often

Incorrect	Correct	Why
“This phone is cheaper then that one.”	“This phone is cheaper than that one.”	Comparing prices → use “than.”
“She would rather text then talk.”	“She would rather text than talk.”	Showing preference → use “than.”
“Turn left, than stop at the gate.”	“Turn left, then stop at the gate.”	Order of actions → use “then.”
“Less then an hour remains.”	“Less than an hour remains.”	Comparing time to one hour → use “than.”
“If you’re finished, than hand in the quiz.”	“If you’re finished, then hand in the quiz.”	Result or consequence → use “then.”

The error you will see most often is “then” used where a comparison needs “than”: “more then,” “better then,” “less then,” and “rather ... then.” In those phrases, the sentence is comparing, so “than” is the correct spelling.

Sentences Where Meaning Can Shift

Sometimes both words can be grammatical, but they do not say the same thing. In those cases, the then vs than choice changes the meaning of the whole sentence.

“I would rather work than wait.” (Comparison: I prefer working to waiting.)

“I would rather work, then wait.” (Sequence: I want to work first and wait afterward.)

Both versions can be correct, depending on what you mean. The first is about preference, so it takes “than.” The second is about order, so it takes “then.”

“The answer is no more useful here than there.” (Comparison of usefulness in two places.)

“She checked the front desk, and then she went upstairs.” (A sequence of actions.)

How the Words Sound

In careful pronunciation, “then” and “than” do not have the same vowel. “Then” sounds like “pen” and uses /ɛ/. “Than” sounds like “can” and uses /æ/. In quick everyday speech, though, both words can be reduced and sound very similar, often like /ðən/. That overlap is one reason the spelling mix-up sticks around.

If you are proofreading, try saying the sentence slowly and exaggerating the vowel: then for time, than for comparison. Hearing the difference can help you notice a wrong choice on the page.

Try It Yourself

Fill in each blank with “then” or “than.”

This chair is more comfortable _____ the old one.
We locked the doors, and _____ turned off the lights.
Marcus has less free time _____ his sister.
If the printer jams, _____ restart it.
I’d rather arrive early _____ miss the opening song.
Back _____, the town had only one grocery store.
The repair cost more _____ I expected.
Mix the flour, _____ add the milk slowly.
Our dog is bigger _____ our neighbor’s dog.
If the wind gets stronger, _____ we’ll move the party indoors.

Answer Key

than (Comparing one chair to another.)
then (Sequence: after locking the doors.)
than (Comparing free time.)
then (In that case.)
than (Comparing preferences.)
then (At that earlier time.)
than (Comparing cost to expectation.)
then (The next step.)
than (Comparing size.)
then (In that situation.)

The Main Takeaway

Keep the difference simple: then belongs with time, order, and results; than belongs with comparisons and preferences. If you can substitute “next” or “after that,” choose “then.” If the sentence compares one thing with another, choose “than.” The E/A reminder also helps: thEn for timE, thAn for compArison.
