Bar charts are a common IELTS Academic Writing Task 1 question type. In this guide, you will learn how to identify the main features, organise a four-paragraph report, use accurate comparison vocabulary and check your work against the assessment criteria. You can also study three practice questions and a complete model report.

1. Question Overview
An IELTS bar chart, also known as a bar graph, is one of the visual formats you may encounter in Academic Writing Task 1. The full Writing test lasts 60 minutes. You should spend about 20 minutes on Task 1 and write at least 150 words. Task 2 contributes twice as much as Task 1 to the Writing score, so protect enough time for both tasks. These timings and scoring details follow the official IELTS Academic Writing test format.

Explore the IELTS course1.1 Objective
The aim is to produce a report of at least 150 words that summarises the data rather than explaining or interpreting causes. Select the main features, support them with relevant figures and make meaningful comparisons where appropriate.
1.2 Skills Used
This task assesses your ability to:
- Select and summarise the key features of a chart
- Identify trends in information
- Describe and compare data
- Produce a report using a formal register
2. IELTS Bar Chart Sample Questions
A bar chart presents data using horizontal or vertical rectangular bars. You may also receive two related charts that must be summarised and compared in one response. Read the task statement and every label before you plan. Depending on the visual, check:
- The subject and scope described in the task statement
- The categories on the horizontal and vertical axes
- The unit of measurement, such as a number, percentage, currency or time
- The dates, colour key or legend, where provided
2.1 Sample Question 1- Horizontal Bar Chart
You should spend about 20 minutes on this task.
The graph below shows the number of international graduates from UK universities in 2000 and 2015.
Summarise the information by selecting and reporting the main features and make comparisons where relevant.
Write at least 150 words.
2.2 Sample Question 2- Vertical Bar Chart
You should spend about 20 minutes on this task.
The graph below compares estimated wild gorilla populations in seven African countries in 1990 and 2015.
Summarise the information by selecting and reporting the main features and make comparisons where relevant.
Write at least 150 words.
2.3 Sample Question 3- Two Bar Charts Presented
You should spend 20 minutes on this task.
The graphs below give information about computer ownership as a percentage of the population between 2000 and 2010, and by level of education for the years 2000 and 2010.
Summarise the information by selecting and reporting the main features and make comparisons where relevant.
Write at least 150 words.
3. Structure for Bar Chart Reports
A strong Academic Writing Task 1 report normally follows a clear four-paragraph structure: an introduction, an overview and two body paragraphs. A separate conclusion is unnecessary because the overview already summarises the main features.
A simple four-step method
- Analyse: read the title, labels, units, categories and dates. Identify what is being compared.
- Select: choose two or three main features for the overview, then group the remaining evidence logically.
- Write: paraphrase the task, state the overview, and support two body paragraphs with selected figures and comparisons.
- Check: verify every number, unit, tense and comparison. Remove opinions, causes and repeated information.
Use the same decision process when you practise, while adapting the paragraph groups to the specific chart.
3.1 Introduction
Your introduction should always paraphrase the given statement, meaning you should write it again in your own words. Memorising some good phrases to start a bar graph should help as well, but make sure the phrase you use is relevant to the given IELTS bar graph in the real exam. Let’s have a look at some examples below:
- The bar chart shows / presents
- The bar graph compares
Paraphrasing demonstrates to the examiner that you have fully
understood the meaning of the writing task 1 statement and that you
have the knowledge and understanding to be flexible with the
language. The aim is to change the words and structure of the
original statement whilst maintaining the meaning of the text.
Successful paraphrasing may involve some of the
following:
- Using synonyms/parallel expressions
- Changing the word order of the sentence
- Changing the phrase from active to passive
- Changing the form of words (e.g., noun to verb)
Example of paraphrasing
Original statement:
The chart shows consumer spending on luxury goods in the UK in 2010
and 2020.
Paraphrased statement:
The chart illustrates the amount of money spent on
luxury goods (foreign holidays, high-end vehicles, designer clothes
and spa services) by consumers in the United Kingdom in the years
2010 and 2020.
Other things to consider when writing your introduction of a bar
chart:
- You do not need to change every word to paraphrase a text successfully
- You may list given categories ( if the list is not too long). Use the word For instance, The bar graph presents wine production data in liters in three countries, namely Australia, New Zealand and Canada.
- Include any dates as this is important for tense
- Use brackets to put data and information inside
- Write 1-2 sentences maximum
- Look at the chart itself to see if there is any additional information to introduce not given in the statement
- This should be your most straightforward paragraph to write. Don’t spend too much time here and move onto your overview and main body paragraphs
3.2 Overview
Your aim in Academic Writing Task 1 is to produce a clear overview that selects and describes the main features or trends in the bar chart. The overview is essential: the official Task Achievement descriptors distinguish a Band 6 response that attempts a relevant overview from a Band 5 response that may recount details mechanically without a clear overview. Read the IELTS Writing band descriptor guide for a full explanation.
You do not need to write a conclusion for task 1. A conclusion summarises the main ideas of a text. Your report is too short to do this, and you will end up repeating yourself which is something you want to avoid.
Typically, your overview should come directly after your introduction (recommended). However, you may find some sample reports where the overview comes at the end of the report.
Here are some key things to consider when writing your overview:
- Start your overview with ‘Overall’ to make it easy for the examiner to locate your overview paragraph. Other possible words / phrases are:
- It is clear from the graph that….
- Broadly, it can be seen that..
- There could be 2, 3, 4 or even 5 key features in your chart (we recommend you focus on 2-3)
- Your key features should stand out as the highest or overall figures in some way
- Describe the overall pattern, such as the highest and lowest categories, a clear ranking, a shared trend, or a notable exception
- You should not give precise figures for your overview, save this for your main body paragraphs
3.3 Main Body Paragraphs
Two main body paragraphs are usually the clearest way to group the selected details. This is a practical structure rather than a fixed scoring rule: the important point is that the organisation is logical and easy to follow.
There are different ways you could choose to organise your paragraphs depending on the data. For example:
Main Body Paragraph 1– Compare the highest and lowest categories in the dataset
Main body paragraph 2– Summarise and compare the other categories
The content of your body paragraphs will depend on the chart, but here are some general points to consider:
- Make sure to use the correct tense (look carefully at the given dates, are they in the past, present, future, or perhaps they range from the past to the predicted future)
- Determine whether the chart compares categories at one point in time, shows change over time, or does both
- Always provide data and support your sentences with numbers
- Do not just provide a long list of numbers; the examiner will check every number and they need to be accurate and clear for the reader
- Use symbols given to you on the axis for currency, percentage etc. (e.g., £, $, %)
- Avoid repetition
4. IELTS Writing Task 1 Band Descriptors Explained
4.1 Task Achievement (25%)
To achieve a high band score in task achievement, you must:
- Produce a factual report (use a formal register; do not give your opinion; avoid the first person ‘I’)
- Write at least 150 words (you need to be able to sufficiently develop your ideas)
- Report and compare the key features of the chart (do not try to describe every detail of the chart)
- Provide a relevant overview that clearly highlights the main features; the public descriptors distinguish this from a Band 5 response that may recount details without a clear overview
- Accurately describe the data
4.2 Coherence and Cohesion (25%)
To achieve a high band score in Coherence and Cohesion of your bar chart task 1, you must:
- Organise your report logically
- Use paragraphs (include an introduction, an overview, and two main body paragraphs)
- Use a range of linking devices accurately and appropriately
- Use referencing effectively to avoid repetition (e.g., using ‘this’ to refer to refer back in your text to a noun/noun phrase)
4.3 Lexical Resource (25%)
To achieve a high band score in Lexical Resource of task 1 bar graph, you must:
- Use a range of Academic Task 1 vocabulary appropriate for describing bar-chart data
- Show understanding of collocations
- Avoid making spelling mistakes
- Use an appropriate register throughout the report (e.g., avoid slang/ phrasal verbs/ idioms)
4.4 Grammatical Range and Accuracy (25%)
To achieve a high band score in Grammatical Range and Accuracy, you must:
- Use the correct tense according to your data set (confirm if your data is taken from the past, present, future, or a combination, and use the corresponding tense in your report)
- Use a range of simple and complex sentences (e.g., compound, relative, or subordinate sentences)
- Avoid grammatical errors
- Use punctuation accurately
What separates a Band 6, 7 and 8 response?
| Target | What the response usually demonstrates | What to improve next |
|---|---|---|
| Band 6 | Addresses the task, presents a relevant overview and includes adequate detail, although some information may be unclear or inaccurate. | Make the overview more selective, group data more logically and check figures carefully. |
| Band 7 | Presents a clear overview, identifies main trends or differences and categorises the data appropriately. | Make comparisons more precise and maintain flexible, accurate grammar and vocabulary. |
| Band 8 | Covers all task requirements sufficiently, selects key features skilfully and presents them clearly with well-managed detail. | Remove minor lapses in precision, cohesion, word choice and sentence control. |
This is a practical summary, not a score guarantee. Consult the official IELTS Writing band descriptors for the complete wording.
5. Vocabulary for IELTS Bar Charts
5.1 Vocabulary for Accuracy
When describing bar graph IELTS task 1, you will often find that a figure cannot be precisely determined and you have to estimate the number. To show flexibility with your language, you can use words and phrases to estimate the figures. Here is some useful language to help you write about numbers that are above, below or approximate figures:
| Under | Over | About |
|---|---|---|
| Considerably less than | Considerably more than | Approximately |
| Just under | Slightly over | Around |
| Close to | Marginally above | Roughly |
| Slightly under | Well over | Near to |
| Less than | More than | In the region of |
| Almost | Just over | |
| Nearly |
5.2 Linking Devices
In order to create cohesion throughout your report, you should use a range of linking devices appropriately. Here are some useful linkers to create contrast when writing about bar charts:
- whereas
- while
- as opposed to
- compared to
Examples
80% of people owned a computer in 1990, whereas/while only 30% owned one in 1980.
Only 30% of people owned a computer in 1980 as opposed to/compared to 80% in 1990.
5.3 Language for Reference
Using the words ‘respectively’ or ‘in turn’ is an efficient and accurate way to refer back to specific
figures in your writing task 1 report. It will also help to avoid
unnecessary repetition and
improve your lexical resource score.
When using these terms, the order of the numbers follows the order in the sentence. You can also use brackets to contain the figures.
Examples
The price of oil and gas in 1990 was almost the same (about $100 and
$110, respectively).
Espressos were considerably less popular than café lattes, at 25 and 135 sales per week respectively.
6. Grammar for Bar Charts IELTS Task 1
6.1 Comparatives
You can use comparative structures to improve your range of grammar and compare the data in the bar chart/s. For example:
You can also use words together with comparative forms to indicate a small or a big difference:
- much
- a lot
- slightly
- a bit
- considerably
Examples:
Americanos were considerably more popular than espressos.
Cappuccinos were slightly more popular than caramel lattes.
6.2 Superlatives
Superlatives are a useful way to rank or order information.
Examples:
- Travelling by plane is the most expensive way to travel, at an average of £100 per ticket.
- The second most expensive is by train, where it costs around £30.
- The least expensive form of transport is by bus, coming in at £20 per ticket.
6.3 Advanced Comparisons
- X is not as + adjective + as y e.g., Coffee in Brazil is not as expensive as in America.
- Not + verb + as + noun phrase + as e.g., Coffee in Brazil does not cost as much as in America, at $2 and $2.90, respectively.
- Three times / half / twice as much as, e.g., Coffee in America costs twice as much as in Brazil.
- The number of X is three times as high as the number of Y, e.g., The number of people buying coffee in Brazil is three times as high as the figure for America.
7. IELTS Bar Chart Sample Answer
The chart shows data about the average weekly sales of two coffee shops in New York in 2015.
Summarise the information by selecting and reporting the main features and make comparisons where relevant.
Sample
The bar chart compares the average weekly sales of eight coffee drinks at two coffee shops in New York in 2015: Club Coffee and Espresso Express.
Overall, Club Coffee sold more drinks in five of the eight categories, while the two shops recorded the same figure for espressos. Café lattes were the best-selling item at both shops. Espresso Express led only in sales of flat whites and caramel lattes.
At Club Coffee, café lattes ranked first at approximately 135 sales per week. Cappuccinos and Americanos followed at about 115 and 100 respectively. The shop sold around 80 decaf coffees and 70 iced coffees, while flat whites were lower at roughly 40. Espressos and caramel lattes were the least popular items, at approximately 25 and 18.
At Espresso Express, café lattes also ranked first, at just over 120 weekly sales, followed by Americanos at around 75 and cappuccinos at about 65. Caramel lattes accounted for approximately 60 sales, while decaf coffees and flat whites were level at 50. Iced coffees were slightly lower at around 45, and espressos had the smallest figure, at approximately 25.

7.1 Model Answer Commentary
This model is designed to illustrate high-band features; it is not an official examiner score or a score guarantee.
- Clear structure: the response uses an introduction, a selective overview and two body paragraphs divided by coffee shop.
- Accurate overview: it identifies the dominant category at both shops, the five categories led by Club Coffee, the one equal category and the two categories led by Espresso Express.
- Selective evidence: the body paragraphs include enough figures to support the comparisons without listing the chart mechanically.
- Precise language: terms such as “approximately”, “followed by”, “while” and “respectively” communicate estimates, ranking and contrast.
- No unsupported interpretation: the report describes only what the chart shows and does not speculate about customer preferences or causes.
For a broader list of useful terms, study the Academic Task 1 vocabulary guide. To practise the same comparison skills with a mixed visual, see the table and bar chart guide or the bar and pie chart guide.
Once you can analyse the model, test the method on a new chart through an IELTS course with teacher-marked writing and complete practice sets.
8. Common Errors and How to Avoid Them
8.1 Problem 1
Not understanding what information to include in your bar chart report.
Solution 1
Take a short amount of time, before you even start writing, to identify the key features of the
chart. It will be worth investing this time in finding the highest,
lowest or most interesting key features instead of wasting time
trying to write about every detail
8.2 Problem 2
Using trend language without checking whether the chart includes a time series. Bar charts can compare categories at one point in time, show changes across dates, or combine both. A line graph often emphasises movement over time, but the chart type alone does not determine the language.
Solution 2
Check the dates and the relationship between the bars. Use verbs
such as “rose”, “fell” or “remained stable” only when the same
category is measured across time. When the chart compares different
categories at one time, use comparative language such as “higher
than”, “lower than” or “twice as high as”.
Time-series bar chart: The proportion rose from 30% in 2000 to 45% in 2010.
Category comparison: The figure for X was 15 percentage points higher than the figure for Y.

10. IELTS Bar Chart FAQs
How do I start an IELTS bar chart report?
Start with one sentence that paraphrases what the chart shows. Include the subject, place, period and unit if they are given, but do not copy the task wording.
What should I write in the overview?
State the two or three most important features: for example, the highest and lowest categories, the dominant ranking, a major similarity or difference, or a clear overall change. Avoid precise figures unless they are essential to the main pattern.
Do bar charts always require comparison language?
Usually, because the task asks you to select and compare key features. If the bars show dates, you may also need trend language. Choose language from the relationships visible in the data rather than from the visual type alone.
How many comparisons should I include?
There is no fixed number. Make enough comparisons to explain the main features and support each body paragraph, while avoiding a mechanical description of every bar.
Can I give reasons for the figures?
No, unless the task itself provides those reasons. Academic Task 1 assesses your ability to summarise the visual information, not to speculate or give an opinion.
Is a conclusion required for IELTS Writing Task 1?
No. A clear overview is essential, but a separate conclusion normally repeats information and is unnecessary.
