IELTS Writing Task 1: Chart & Letter Structure

IELTS Writing Task 1 rewards clear structure and precise language. Here's how to describe charts, graphs, maps and processes to hit Band 7+.

Task 1 question types

Task 1 gives you a visual — a bar/line/pie chart, a table, a map or a process diagram — and asks you to describe it in 150+ words. Unlike Task 2 essays, Task 1 is purely factual: you summarise key features, highlight trends and compare data without opinion. The key is accuracy and organisation.

The winning structure for charts

Introduction (paraphrase the visual + overview of main trend), Body (2–3 paragraphs describing key data, comparisons and patterns), Conclusion (recap the main takeaway). Use the overview paragraph to signal what you will describe in the body — examiners reward this 'roadmap'.

Vocabulary and language for Task 1

Use present simple and passive voice (the highest point is reached, there was a rise in). Master trend verbs: increase, decrease, fluctuate, plateau, peak, plummet. Use comparison language: whereas, in contrast, compared to. Avoid repetition by using synonyms. Precision matters more than complexity.

Common traps and how to avoid them

Do not add opinion or interpretation beyond what the data shows. Do not repeat the same figures. Do not write over 190–200 words (examiners penalise you for exceeding the word limit). Do not use the same sentence structure repeatedly — vary your syntax.

Letter vs Report (Academic vs General)

Academic Task 1 is always a visual; General uses formal letters or semi-formal emails instead. For letters, follow a clear structure: address the recipient, state your purpose, explain your points, and close politely. Formal letters need appropriate greetings and sign-offs.

Frequently asked questions

What is the word count for IELTS Writing Task 1?
Minimum 150 words. Examiners penalise you for writing fewer. Aim for 160–190 words; over 200 is flagged as exceeding the requirement.
How much does Task 1 count towards the overall band?
Writing is 25% of your overall IELTS band, and Task 1 and Task 2 are equally weighted. So Task 1 strongly affects your Writing and overall score.
Is it better to describe all the data or just the main features?
Describe the key features and trends, not every single number. Your overview paragraph should signal what you will focus on so the examiner expects your selection.
