In line and inline are both correct, but they are used in different ways. The right choice depends on what you mean.
Use in line when you mean in a row, in a queue, aligned, or consistent with something:
We waited in line for tickets.
The results are in line with expectations.
Use inline when you mean included within, built into, or placed directly within something else:
The editor supports inline editing.
The article contains inline images.
So, in line with expectations is correct. Inline with expectations is not the normal form for that meaning.
Quick Answer
| Form | Meaning | Example |
|---|---|---|
| in line | In a row or queue | We stood in line. |
| in line with | Consistent with or matching | Sales were in line with expectations. |
| inline | Included within or built into something | The page supports inline editing. |
| online | Connected to the internet | I completed the form online. |
| in-line | Hyphenated form used in some established compounds | An in-line engine |
The key is not simply the number of words. Meaning and context determine the correct form.
What Does “In Line” Mean?
In line is a two-word phrase. Its most common meanings relate to position, arrangement, or agreement.
In a Queue
When people wait one behind another, use in line:
- We waited in line outside the store.
- The children stood in line for lunch.
- Please get in line behind the other customers.
In a Row or Position
It can also describe things arranged in a row:
- The chairs are in line along the wall.
- Keep the boxes in line with the markings.
- The cars were parked in line.
Consistent With Something
In the phrase in line with, it means consistent with, compatible with, or aligned with something:
- The results are in line with expectations.
- The new policy is in line with company goals.
- Her decision was in line with the rules.
- The price is in line with similar products.
This meaning is especially important because inline cannot normally replace in line here.
What Does “Inline” Mean?
Inline is a one-word form with several established uses.
Its general idea is that something is within, incorporated into, or directly part of another structure or flow.
For example:
- inline editing
- inline code
- inline images
- inline links
- inline elements
- inline comments
In technology and digital writing, inline is especially common.
For example:
The website allows inline editing.
This means users can edit the content directly where it appears instead of moving to a separate editing screen.
In Line With or Inline With?
If you mean consistent with, matching, or aligned with, use:
in line with
For example:
The results are in line with expectations.
The decision is in line with company policy.
The proposal is in line with our goals.
Do not normally write:
The results are inline with expectations.
Here, inline has a different meaning and should not be used as a replacement for the phrase in line with.
“In Line With Expectations”
In line with expectations means that something is approximately what people expected.
For example:
The company’s sales were in line with expectations.
The exam results were in line with expectations.
You could also say:
- as expected
- consistent with expectations
- matching expectations
- in keeping with expectations
But in line with expectations is a natural and widely used phrase.
Inline in Technology and Computing
The word inline appears frequently in technical writing.
Common terms include:
- inline code
- inline CSS
- inline HTML
- inline element
- inline editing
- inline image
- inline link
- inline comment
- inline function
For example:
The developer added inline CSS to the element.
The documentation uses inline code for short commands.
Users can make inline edits without leaving the page.
In these contexts, writing in line would normally change the intended technical term.
In Line or Inline in a Sentence
Here are some clear examples.
Examples of “In Line”
We stood in line for coffee.
The students were in line outside the classroom.
The figures are in line with the forecast.
Her decision was in line with company policy.
The desks were arranged in line.
Examples of “Inline”
The article contains inline links.
The software supports inline editing.

The image appears inline with the text.
The website uses inline styles.
The forms are not interchangeable. The meaning of the sentence tells you which one to use.
In Line or Inline for Alignment?
This depends on what you mean by alignment.
If you mean that people or objects are arranged in a row, use in line:
The chairs are in line with the windows.
If you mean that something is incorporated into existing content or a technical structure, inline may be correct:
The image is displayed inline with the text.
There is also a very common figurative use:
The plan is in line with our objectives.
Here, in line with means aligned with or consistent with, not physically arranged in a line.
In Line vs Inline vs Online
These three forms are easy to confuse, but they have different meanings.
In line
Used for a queue, row, position, or consistency:
We waited in line.
The plan is in line with our goals.
Inline
Used for something incorporated into another structure:
The page contains an inline image.
Online
Used for something connected to or operating through the internet:
I paid the bill online.
So:
in line ≠ inline ≠ online
Do not choose between them based only on how they sound.
In Line vs On Line
In line is the standard general expression for waiting in a queue:
We waited in line for tickets.
You may also hear on line, particularly in some regional American English, including New York City speech.
That does not make on line interchangeable with online.
Compare:
I waited in line at the store.
I completed the application online.
The first describes a queue. The second refers to the internet.
For general writing, in line is the safest choice when you mean a queue.
Is “In-Line” Correct?
Yes, in-line can be correct in certain established compounds.
For example:
- in-line engine
- in-line production
- in-line inspection
However, you should not add a hyphen simply because you are unsure whether in line should be one word.
Compare:
We waited in line.
The system uses an inline feature.
The vehicle has an in-line engine.
The spelling depends on the expression and its meaning.
Common Mistakes
“Inline with expectations”
Incorrect for the intended meaning:
The results were inline with expectations.
Better:

“We stood inline”

When you mean a queue, use the two-word phrase.
“In line editing”
If you mean editing directly within existing content, use:
inline editing
“In line code”
In technical writing, the established term is:
inline code
The difference is not just spelling. The words form different grammatical and technical expressions.
