IELTS Writing Task 1: Line Graph Template for Band 8
Quick answer: An IELTS line graph Task 1 follows the 4-paragraph template (introduction, overview, body 1, body 2). The dominant vocabulary is trend verbs (rose, climbed, plateaued, declined) paired with adverbs of degree (sharply, gradually, slightly). Aim for 170–195 words in 18 minutes.

Line graph sub-types
Single line: one variable over time. Describe the overall trajectory and 1–2 key turning points.
Multiple lines (2–4 lines): compare across categories and time. The most common Task 1 line graph format.
Multiple Y-axes: rare but possible. Be careful to associate each line with its correct axis.
Template structure
Introduction: paraphrase the question. Include time period and units. "The line graph illustrates [X] from [Y] to [Z], measured in [units]."
Overview: 2 main trends without numbers. "Overall, [variable A] showed [direction] while [variable B] [contrast]."
Body 1: dominant trend with figures, turning points, and rate of change.
Body 2: secondary trend or comparison line.
Trend vocabulary by direction and speed
Sharp rise: surged, soared, skyrocketed, shot up.
Steady rise: rose, increased, climbed, grew, expanded.
Slow rise: edged up, crept up, ticked up, gradually rose.
Sharp fall: plummeted, plunged, crashed, dropped sharply.
Steady fall: fell, declined, decreased, shrank.
Slow fall: dipped, slipped, edged down.
No change: plateaued, levelled off, remained stable, held steady.
Fluctuation: fluctuated, oscillated, varied.
- Pair every trend verb with an adverb: "rose sharply", "declined gradually", "fluctuated wildly"
- Mix verb-noun pairs: "there was a sharp rise" alternates with "the figure rose sharply"
- Use "reached a peak of" / "hit a low of" for extremes
Worked Band 8 example
Question: line graph showing internet users (millions) in three countries — UK, India, China — from 2000 to 2024.
Introduction: "The line graph illustrates the number of internet users, in millions, in the United Kingdom, India, and China between 2000 and 2024."
Overview: "Overall, internet usage rose dramatically in all three countries over the period, with China leading throughout. India experienced the steepest acceleration, while the UK showed steadier, more modest growth."
Body 1: "China's internet user base climbed from 22 million in 2000 to over 1 billion by 2024 — a fifty-fold increase. The growth was particularly steep between 2005 and 2015, during which China added approximately 600 million new users."
Body 2: "India followed a similar but later trajectory: starting from just 5 million users in 2000, it surged to roughly 800 million by 2024, with most of the growth concentrated post-2014. The UK, by contrast, grew more gradually from 15 million to 65 million over the same period — a comparatively modest fourfold increase."
Common line graph mistakes
Mistake 1: describing every data point. Pick turning points and overall direction only.
Mistake 2: forgetting to compare lines (in multi-line graphs). The instruction asks for comparisons.
Mistake 3: tense errors. Past data uses past simple; projections use will/is expected to.
If the graph extends into the future, switch to future tense for forecast portions: "is projected to reach", "is expected to climb".
Time management
3 minutes planning. Identify 2 most important trends.
13 minutes writing.
2 minutes proofreading. Check tense consistency and word count (170–195 ideal).

Frequently Asked Questions
How many figures should I include?
5–8 specific figures across body paragraphs. Anchor extremes (peak, trough), turning points, and start/end values.
What tense should I use?
Past simple for past data. Present simple for general patterns. Future tense for projections.
Can I describe lines one at a time or compare directly?
Direct comparison scores higher because the instruction asks for comparisons. Avoid describing each line in isolation.
Should I mention every data point?
No. Selectivity is rewarded. Pick the data points that illustrate the main trends.
How long should body paragraphs be?
55–70 words each. Together with 30 words intro and 35 words overview, you reach 175–205 total.
What if two lines cross?
Highlight the crossover point: "the two figures converged in 2015 before diverging again". Crossovers are key features.
