IELTS Writing Task 1 Band 7: Charts, Graphs and Maps Complete Guide (2026)

Quick answer: Academic Writing Task 1 asks you to describe a chart, graph, table, map or process in at least 150 words within 20 minutes. Band 7 needs four things at once: (1) a paraphrased introduction that does not copy the prompt; (2) a clear overview paragraph stating the two or three biggest patterns — missing this caps you at 5; (3) two body paragraphs grouping data by trend, magnitude or category, never listing every number; (4) accurate trend and comparison language (rose sharply, fell marginally, plateaued, fluctuated, in stark contrast). Aim for 160–180 words; under 150 triggers an automatic Band 5 cap. Free AI Task 1 feedback at English AIdol IELTS.

Why Task 1 is the section students under-prepare

Task 1 is one-third of your Writing band, and the gap between Band 6 and Band 7 here is small but stubborn. Most candidates over-prepare Task 2 essays and treat Task 1 as a quick warm-up. The result is predictable: a Band 6.5 in Task 2 paired with a Band 6.0 in Task 1 gives a Writing band of around 6.0 — half a band below where the candidate could have landed with twenty extra hours of Task 1 practice.

The honest news: Task 1 is more formulaic than Task 2. The structure is fixed, the vocabulary is finite, and the four scoring criteria reward the same handful of habits on every chart, every graph, every map. Once you internalise the structure and the vocabulary lists in this guide, Band 7 in Task 1 is a question of reps, not talent.

The five chart types you will see

IELTS Academic Task 1 prompts come from a fixed menu. Knowing the menu means you walk into the test having already practised every type.

• Bar chart — vertical or horizontal bars comparing categories or time points. Approximately 25% of recent tests.
• Line graph — one or more lines tracking change over time. Approximately 25% of recent tests.
• Pie chart — proportions of a whole, single year or compared across two years. Approximately 15%.
• Table — rows and columns of numbers. Approximately 10%.
• Mixed / multiple charts — two of the above shown side by side, requiring cross-comparison. Approximately 15%.

The remaining ~10% of tests show a map (describing changes to a location over time, e.g. a town in 1990 vs 2020) or a process diagram (describing how something is made or how a natural cycle works). Both are rarer but tested often enough that you must practise at least two of each before test day.

The 4-paragraph Band 7 structure

Every Task 1 answer follows the same four-paragraph shape. The structure itself is worth marks under Coherence and Cohesion.

Paragraph 1 — Introduction (1–2 sentences, ~25 words)

Paraphrase the prompt. Do not copy it word for word. Replace key nouns and verbs with synonyms.

• Prompt: "The bar chart below shows the percentage of households owning a car in five countries between 2000 and 2020."
• Paraphrased intro: "The chart illustrates car ownership rates among households in five nations across a two-decade period from 2000 to 2020."

Paragraph 2 — Overview (2–3 sentences, ~40 words) — THE MOST IMPORTANT PARAGRAPH

State the two or three biggest patterns visible in the data. No specific numbers here. The overview is where examiners decide whether you scored 7 or 5 on Task Achievement.

• What rose, what fell, what stayed flat?
• What was the highest / lowest at the start vs the end?
• What is the single most striking feature?

Start with: "Overall, …" or "It is clear that …" or "Broadly, …"

Paragraph 3 — Body 1 (3–4 sentences, ~50 words)

Topic sentence + supporting data. Group the data logically — by category that rose, by region that led, by period of stability — never go left-to-right reciting every number.

Paragraph 4 — Body 2 (3–4 sentences, ~50 words)

The remaining group. Cross-reference Body 1 where appropriate using comparison language ("in contrast," "similarly," "by comparison").

The 20-minute time budget

• 3 minutes — read the prompt, study the chart, decide how to group the data, identify the 2–3 biggest patterns for the overview.
• 15 minutes — write the four paragraphs at a steady pace.
• 2 minutes — proofread for tense (past for historical data, present for general charts), articles, plurals, and word forms.

Aim for 160–180 words. The minimum is 150; under-length is a heavy penalty (Band 5 cap regardless of quality). Above 200 you start eating Task 2 time, which is twice as valuable.

Trend vocabulary — the language of change

Half of Task 1 marks come from describing change accurately. Memorise these in clusters of three.

Increase (verbs)

• Slight: edged up, crept up, inched higher
• Steady: rose, increased, climbed, grew
• Sharp: surged, soared, jumped, rocketed, shot up

Decrease (verbs)

• Slight: dipped, slipped, eased
• Steady: fell, declined, decreased, dropped
• Sharp: plunged, plummeted, collapsed, crashed

Stability and fluctuation

• plateaued, levelled off, remained stable, held steady, stayed constant
• fluctuated, oscillated, varied, see-sawed

Reaching extremes

• peaked at, reached a high of, hit a maximum of
• bottomed out at, fell to a low of, troughed at

Adverbs of degree (to pair with verbs)

• Small: slightly, marginally, modestly
• Medium: steadily, gradually, moderately
• Large: sharply, dramatically, significantly, substantially

Noun forms (alternate to verb forms for grammatical range)

• Increase: a rise, a surge, a jump, a marked increase
• Decrease: a fall, a drop, a decline, a sharp decrease
• Stability: a period of stability, a plateau

The Band 7 trick: alternate verb and noun forms in the same paragraph. "Sales rose sharply between 2010 and 2015" followed by "This sharp rise was followed by a plateau." Examiners reward this variation under Lexical Resource and Grammatical Range.

Comparison vocabulary — the language of contrast

Most Task 1 prompts ask you to compare two or more groups. Memorise these phrases.

• Significantly higher / lower than: "Car ownership in Germany was significantly higher than in Vietnam throughout the period."
• Marginally higher / lower than: "France was marginally lower than the UK in 2020."
• Roughly equivalent to / on a par with: "By 2015 Spain was roughly on a par with Italy."
• In stark contrast: "In stark contrast, Vietnam saw almost no change."
• Conversely / By comparison / On the other hand: standard contrast connectors.
• Whereas / While: "Whereas Germany rose steadily, Italy declined."
• Twice / three times / half as much as: "Germany owned roughly twice as many cars per household as Vietnam."

Approximation vocabulary — when not to use exact numbers

Reading every exact figure is the Band 6 mistake. Examiners reward approximation language.

• around / approximately / roughly + number
• just under / just over / a little above / a little below + number
• nearly / almost / close to + number
• slightly / well over / well above + number

Example: "The figure rose to just over 60 percent by 2015" is Band 7. "The figure rose to 61.3 percent by 2015" is Band 6 because it sacrifices range for false precision.

The Topic Sentence + Detail formula for body paragraphs

Each body paragraph follows the same shape:

1. Topic sentence — a generalisation about the group of data. Example: "Among the European countries, Germany consistently led car ownership."
2. Two or three supporting data points — specific numbers using approximation language. Example: "German ownership rose from approximately 70 percent in 2000 to just over 90 percent by 2020."
3. One comparison or trend statement tying it back. Example: "This represented the steepest increase of any nation in the chart."

Avoid: a body paragraph that is just a list of every number. Examiners call this "data dumping" and it caps Task Achievement at 6.

Model Answer 1 — Bar chart

Prompt: "The bar chart below shows the percentage of households owning a car in five countries between 2000 and 2020."

Model answer (172 words, Band 7+):

The chart illustrates car ownership rates among households in five nations across a two-decade period from 2000 to 2020.

Overall, household car ownership rose in every country shown, although the scale of growth varied considerably. Germany consistently led the group, while Vietnam remained the lowest throughout despite a substantial increase in absolute terms.

Among the European countries, Germany dominated, with ownership climbing from around 70 percent in 2000 to just over 90 percent by 2020. France and the UK followed a similar pattern, both moving from roughly 60 percent at the start of the period to approximately 80 percent by the end. Italy lagged slightly behind, ending the period at around 75 percent.

In stark contrast, Vietnamese ownership began at a very low base of just under 10 percent in 2000 but more than tripled to reach approximately 35 percent by 2020. Although this represented the largest proportional rise of any country in the chart, Vietnam still remained well below the European nations.

Why Band 7+: paraphrased intro, clear overview with two patterns and no numbers, body 1 groups by region, body 2 cross-references body 1 with "in stark contrast," approximation language throughout (around, roughly, just over), trend verbs (climbed, lagged, more than tripled), comparison phrases (significantly, in stark contrast), 172 words.

Model Answer 2 — Line graph

Prompt: "The line graph below shows the number of international visitors to four cities (London, Paris, Rome and Bangkok) between 2010 and 2020 in millions."

Model answer (168 words, Band 7+):

The graph depicts annual international visitor numbers to four major cities — London, Paris, Rome and Bangkok — over an eleven-year period from 2010 to 2020.

Overall, all four cities experienced rising tourism throughout the decade, though the pattern was disrupted in 2020. London and Paris consistently received the highest visitor numbers, while Bangkok recorded the steepest growth before the 2020 decline.

London and Paris followed remarkably similar trajectories. Both rose steadily from approximately 16 million visitors in 2010 to roughly 21 million by 2019. Rome trailed behind these two, climbing from around 9 million to just over 12 million across the same period.

By comparison, Bangkok showed the most dramatic growth. Its visitor numbers surged from a base of approximately 11 million in 2010 to a peak of nearly 24 million by 2019 — overtaking even Paris. However, in 2020 all four cities suffered a sharp decline, with Bangkok plummeting most heavily, dropping by roughly two-thirds to around 8 million.

Why Band 7+: trends grouped by similarity (London + Paris together), one outlier story (Bangkok), the 2020 dip noted in the overview, vocabulary range (rose, climbed, surged, plummeted), comparison language (remarkably similar, by comparison, overtaking), 168 words.

The seven mistakes that cap most candidates at Band 6

1. Copying the prompt verbatim as your introduction. Examiners ignore copied text when counting words; you can drop below 150 without realising it.
2. Missing the overview paragraph entirely — the single fastest way to a Band 5 ceiling on Task Achievement.
3. Including specific numbers in the overview when the overview is supposed to summarise patterns, not data.
4. Listing every data point rather than grouping by trend, region or magnitude. Examiners call this "data dumping."
5. No comparison language at all — every Task 1 prompt asks you to compare. If you do not, Task Achievement caps at 6.
6. Tense slippage — drifting between past and present in the same paragraph. Use simple past for historical data; present for timeless charts (e.g. a process diagram).
7. Word count violations — under 150 words triggers an automatic Band 5 cap on Task Achievement, no matter how good the rest is.

Maps and process diagrams — the rarer formats

Maps

Two snapshots of the same place at different times (e.g. "The map shows the village of X in 1990 and 2020"). The structure is identical: intro, overview, body 1 (what changed), body 2 (what stayed). Vocabulary shifts to: was demolished, was constructed, was replaced by, was converted into, was relocated, expanded, was extended. Use compass directions: to the north of, in the south-east corner, on the western side.

Process diagrams

How something is made or how a natural cycle works. Use the present passive throughout: is mixed, is heated, is then transferred to, is finally packaged. Sequence connectors: firstly, next, subsequently, after this, in the final stage. Treat each visible stage as one sentence.

• Whether the overview paragraph captured the two or three biggest patterns or missed them.
• Whether your trend vocabulary range was sufficient (it counts the variety of trend verbs used).
• Whether you grouped data logically or fell into the data-dumping trap.
• Sentence-level grammar errors with explanations.
• Word count flag if you fell below 150.

You can submit unlimited Task 1 attempts on the free tier and receive a band-by-criterion breakdown within seconds.

Daily 14-day Task 1 plan

1. Days 1–2: Two bar charts.
2. Days 3–4: Two line graphs.
3. Days 5–6: Two pie charts.
4. Days 7–8: Two tables.
5. Days 9–10: Two mixed/multiple charts.
6. Days 11–12: Two maps.
7. Days 13–14: Two process diagrams.

After each, get an AI band score, identify your weakest criterion, and rewrite the lowest-scoring response of the previous two days using the criterion-specific feedback. Two weeks of this routine moves the median student from Band 6 to Band 7 in Task 1.

Frequently asked questions

What is the minimum word count for IELTS Writing Task 1?

150 words. Falling below triggers an automatic Band 5 cap on Task Achievement, regardless of the quality of the rest. Aim for 160–180 to leave a safety margin in case you under-count or copy something inadvertently.

How should I split time between Task 1 and Task 2?

20 minutes Task 1, 40 minutes Task 2. Task 2 is worth roughly twice the marks. If you spend more than 22 minutes on Task 1 you start eating Task 2 time, which is the worse trade.

Can I get Band 7 in Task 1 without Band 7 in Task 2?

Your Writing band is roughly the average of Task 1 (one-third) and Task 2 (two-thirds). A Band 7 in Task 1 paired with Band 6.5 in Task 2 gives an overall Writing band of approximately 6.5–7.0. So yes, a strong Task 1 raises your Writing band even if Task 2 stays at 6.5.

What are the most common Band 6 mistakes in Task 1?

Five usual suspects: (1) missing or weak overview paragraph, (2) copying the prompt verbatim, (3) listing every number rather than grouping data, (4) no comparison language, (5) word count under 150. Fix the overview first — it is the single highest-leverage repair.

Where can I find free Task 1 sample charts and model answers?
