IELTS Pie Chart: Complete Task 1 Writing Guide

The IELTS pie chart is a common visual used in the Academic Writing Task 1. Many candidates find pie charts confusing at first, but with the right structure, vocabulary, and comparison techniques, scoring a high band is absolutely achievable. This guide will help you understand how to describe pie charts clearly, accurately, and in a band-score-friendly way.

What Is an IELTS Pie Chart?

In IELTS Academic Writing Task 1, a pie chart shows proportions or percentages of a whole, usually divided into categories. You may receive:

  • One pie chart

  • Two pie charts (often for comparison across years or groups)

Your task is to summarize the main features, make comparisons, and report key data, all within at least 150 words.

Common Types of IELTS Pie Charts

Single Pie Chart

A single chart usually shows:

  • Distribution of population

  • Spending habits

  • Usage of resources

Your focus should be on the largest and smallest segments and overall trends.

Two Pie Charts

Two charts are often compared:

  • Different years

  • Different countries or groups

Here, comparison is critical. You must highlight increases, decreases, and contrasts.
