IELTS Academic Writing Task 1: How to Describe Two or More Charts Together

Most Academic Writing Task 1 practice focuses on a single visual — one line graph, one pie chart, one map. But a significant number of real exam questions give you two charts at once: a bar chart and a table, two pie charts, a line graph paired with a pie chart, and so on. Candidates who have only ever practised single visuals often panic, write two disconnected mini-reports, and lose marks for both Task Achievement and Coherence. This guide shows you how to handle multiple charts calmly and score Band 7.

The task is the same — only the planning changes

The rules do not change when you get two charts. You still write at least 150 words in about 20 minutes, and you are still marked on four equally weighted criteria: Task Achievement, Coherence and Cohesion, Lexical Resource and Grammatical Range and Accuracy. What changes is the planning. Before you write a word, spend 60 seconds deciding two things:

1. What does each chart show? Note the units, the time frame (past, present or projected), and the single biggest feature of each.
2. Are the two charts connected? Do they share a category, a total, or a time period you can link — or are they measuring different things entirely?

Your answers decide how you split the report and whether you can make a cross-chart comparison.

The reliable four-paragraph structure

The same four-part shape that works for one chart works for two — you simply give each visual its own body paragraph:

• Introduction (1 sentence): paraphrase the prompt and mention both charts, e.g. "The bar chart shows … while the table gives …".
• Overview (2 sentences): state the main feature of each chart, with no specific figures. This is the paragraph examiners look for first.
• Body paragraph 1: describe the first chart in detail, with selected data.
• Body paragraph 2: describe the second chart in detail, and add one link back to the first where the data connects.

A report with no overview is capped at Band 5 for Task Achievement, and with two charts the overview matters even more because it proves you have read both. If you are unsure how to write those two sentences, our guide to the Task 1 overview paragraph walks through it step by step.

Writing a combined overview

The trick is to summarise each chart in a single clause and join them. Suppose one pie chart shows household spending and a second shows it 20 years later. A strong overview would be:

"Overall, food accounted for the largest share of household spending in both years, though its proportion fell markedly over the period. Meanwhile, the amount spent on leisure and transport rose, becoming a much more significant part of the average budget by the end."

Notice there are no exact percentages — those belong in the body. The overview names the biggest feature of each chart and already hints at the link between them.

Common mistakes with two charts

• Writing two separate essays. Two introductions and two overviews signals you have not seen the task as a whole. Keep one introduction and one overview.
• Trying to report everything. With twice the data, selection matters more, not less. Pick the main features and a few supporting figures; ignore minor detail.
• Forcing a false comparison. If the charts genuinely measure unrelated things, do not invent a link — describe each accurately instead.
• Mixing tenses carelessly. One chart may show past data and the other a projection. Let each chart's time frame fix its tense, and switch deliberately.
• Inventing combined totals. Never add figures across two charts unless the data clearly allows it. Report what is shown.

A quick worked plan

Imagine a line graph of visitor numbers to a museum from 2000 to 2020 and a table showing where those visitors came from in 2020. Your plan might be: introduction naming both; overview saying visitor numbers rose overall and that most 2020 visitors were domestic; body one describing the graph's trend with a few dates and figures; body two describing the table's largest and smallest visitor groups, ending with a sentence linking the record 2020 total to the fact that it was driven by domestic tourists. That single link is what turns two descriptions into one coherent report.

Practise and check your work

Multiple-chart questions reward drilling because the structure is always the same once you have seen a few. Write full 150-word reports against the clock using authentic prompts on our IELTS Writing Questions page, then paste your answer into the IELTS Writing Checker for instant, criteria-based feedback — the free tier gives you one full sample report, so save it for an answer you have genuinely timed.

Plan the split, write one overview for both visuals, and make a single clear link between them — do that, and a two-chart question becomes no harder than one.
