How to describe a line graph in one paragraph

A trend paragraph has three jobs: the overall direction, the exceptional moment, and where the line finished. Everything else is padding. This guide shows how to cover all three in 90–140 words, with the verbs and adverbs that make a trend description precise.

The task

The brief

A line graph shows monthly active users of an app over six months: January 12,000, February 14,500, March 15,000, April 24,000, May 26,000, June 25,500. Write ONE paragraph describing the trend. Identify the overall movement, the sharpest change, and the end state.

Points to cover
  • State the overall direction across the whole period

  • Identify the sharpest change and when it happened

  • Describe how the period ended

  • Use at least three figures from the data

Planning tip: A trend paragraph has three jobs: the overall direction, the exceptional month, and where it finished. Anything else is padding.

What a strong answer does

  • The overall direction comes first and covers the whole period: rose overall, roughly doubled, grew unevenly.

  • The sharpest change is named with its timing: which month, how large, in absolute or percentage terms.

  • The end state is described, including any final dip or levelling off. A small fall at the end is still part of the picture.

  • At least three figures are used, chosen because they mark turning points: the start, the jump, the peak, the end.

  • The trend vocabulary is precise, and the strength of each word matches the size of the change it describes.

  • There is no speculation about why the line moved.

How to structure it

  1. 1

    Overall trend

    20–30 words

    One sentence on the direction across the whole period, with the start and end figures if they make the point.

  2. 2

    The early phase

    20–25 words

    How the line behaved before the main change.

  3. 3

    The sharpest change

    20–30 words

    When it happened and how big it was.

  4. 4

    The end state

    20–30 words

    What happened after the main change, and where the period finished.

Useful phrases

Frames, not finished sentences: put your own details where the [brackets] are, and use only the ones that fit what you are saying.

The overall trend

  • Across the period, [measure] rose overall, from [figure] to [figure].
  • The general direction was upward, although growth was far from even.

Gradual change

  • [Measure] edged up / climbed steadily / grew modestly over [period].
  • Growth slowed to just [amount] in [month].

The sharpest change

  • The biggest movement came in [month], when [measure] jumped by [amount].
  • In a single month, the figure rose by more than [percentage].

The end state

  • [Measure] peaked at [figure] in [month] before slipping to [figure].
  • By the end of [period], the figure had levelled off at around [figure].

Adding precision

  • roughly · just over · just under · nearly
  • a slight / moderate / dramatic increase

Common mistakes, and how to fix them

Month-by-month narration.

A sentence for every data point is a list. The reader has to work out the trend, which is the job the paragraph was supposed to do.

Fix: Lead with the overall trend, then single out only the moments that matter.

Stopping at the peak.

The brief asks how the period ended. Leaving out a final dip hides part of the data and misses a required point.

Fix: Always include the final figure and its direction.

Trend words that do not match the size of the change.

Calling a small rise ‘dramatic’, or a huge jump ‘slight’, misleads the reader.

Fix: Compare the changes first. The biggest gets the strongest verb (‘jumped’, ‘surged’); small ones get ‘edged up’ or ‘rose slightly’.

Preposition errors with numbers: ‘increased with 3,000’, ‘rose till 18,000’, ‘fell of 500’.

Learners from many first languages, including Spanish, Portuguese, German, Hindi and Arabic, map their own prepositions onto English, and each one changes the meaning.

Fix: Use ‘by’ for the size of the change, ‘to’ for the new level, and ‘from … to …’ for both ends.

Tense mixing, or dropped past endings: ‘user increase in April’.

The graph covers a finished period, so the past simple is natural, with the past perfect for ‘by the end of…’. Speakers of Chinese, Vietnamese and Thai often drop the ending because their languages do not mark tense on the verb.

Fix: Use the past simple throughout, and the past perfect after ‘by [time]’.

Explaining the movement.

A reason such as a marketing campaign or a holiday is not in the graph, so it cannot be in the paragraph.

Fix: Describe the movement only.

Before you submit: a self-check

  • Does your first sentence state the overall direction for the whole period?

  • Have you named the sharpest change and when it happened?

  • Have you described how the period ended, including any dip?

  • Have you used at least three figures, correctly?

  • Do your trend verbs match the size of each change?

  • Is it one paragraph of 90–140 words?

Questions people ask

What words can I use to describe trends in a line graph?

For increases: rose, grew, climbed, edged up (small), jumped or surged (large). For decreases: fell, declined, dipped (small), dropped or plunged (large). For no change: remained stable, levelled off, plateaued. Add precision with slightly, steadily, sharply, roughly and just over.


Should I mention every data point?

No. Mention the points that define the shape of the line: the start, the main turning point or jump, the peak and the end. Three to five figures are usually enough for one paragraph.


How do I describe a small drop at the end?

Name it precisely and keep it in proportion, for example that the figure peaked in one month and then slipped slightly. Leaving it out misrepresents the data, and so does exaggerating it.


Does this help with IELTS Academic Task 1?

Yes. Line graphs are among the most common Task 1 formats, and the overview-first habit this paragraph trains is exactly what the task achievement criterion rewards.
