IELTS Academic Writing Task 1 bar charts: how to compare without listing every number

Most people describe a bar chart one bar at a time. It feels safe. It is also the fastest way to stay at Band 6.

By Teacher J · Updated November 2026

The task tells you to “summarise the information by selecting and reporting the main features, and make comparisons where relevant”. Read that again. It does not say “report every number”. It says pick the main features and compare.

So a bar chart answer is not a list. It is a short story about what is the same and what is different.

The mistake almost everyone makes

Look at this

A bar chart shows how many hours a week teenagers in Japan, Spain and Canada spend on sport, games and homework.

In Japan, sport is 5 hours, games are 8 hours and homework is 12 hours. In Spain, sport is 7 hours, games are 6 hours and homework is 9 hours. In Canada...Nine numbers, zero comparisons. The examiner has to do the comparing for you.
In all three countries, homework took up the most time, ranging from 9 hours in Spain to 12 in Japan. Sport, by contrast, was the smallest activity everywhere.One sentence covers six bars. That is what “make comparisons” means.

Step 1: find what is the same everywhere

Before you write, look at the chart for one minute and ask: what is true for every group? In the example, homework is the biggest everywhere. That goes in your overview and in your first body paragraph.

Step 2: find the one that is different

Now ask: who breaks the pattern? Maybe Japan spends far more time on games than the others. That is your second body paragraph.

Same in one paragraph. Different in the other. You do not need a paragraph for each country.

Step 3: use numbers as proof, not as the story

Every comparison needs a number or two to support it. But the comparison comes first, then the number. Not the other way round.

Take a look

Comparing Japan and Spain on games.

Japan games 8 hours. Spain games 6 hours.Two facts sitting next to each other. Still not a comparison.
Teenagers in Japan spent slightly more time on games than those in Spain (8 hours compared with 6).The comparing word does the work. The numbers just prove it.

Words that compare

You do not need fancy words. You need words that put two things side by side:

  • the most / the least
  • by far the most
  • twice as much as
  • slightly more than / a little less than
  • by contrast, whereas, while
  • the one exception was

Your 20-minute plan

  1. 1 minute: what is the same everywhere? What is different?
  2. 2 minutes: write the overview with no numbers.
  3. 14 minutes: two body paragraphs, same then different, each comparison backed by one or two numbers.
  4. 3 minutes: check every paragraph compares at least two things.
