PTE Describe Image Chart Selection Guide [2026]

You open a PTE Describe Image prompt and see a chart packed with bars, labels, years, and percentages. Your eyes try to collect everything before the preparation timer runs out. Then the recording begins, and the answer turns into a list of numbers with no clear point.

That moment is familiar to many candidates. The problem is often not understanding the chart. It is deciding what deserves space in a short spoken response. A chart may contain far more information than you can use, so the useful skill is selection, explain the overall subject, choose a few details that support it, and make the relationships easy to follow.

Pearson gives candidates 25 seconds to prepare and 40 seconds to respond. Describe Image is assessed on content, oral fluency, and pronunciation, and a human expert reviews the content before the task score is confirmed. A fixed opening sentence cannot choose the chart’s key information for you. The method below helps you make that decision while the timer is running. See Pearson’s official Speaking and Writing task guide for the current task instructions.

01 Give the chart a one-sentence overview

Before reading every value, identify what the chart is about. Check the title, axes, labels, units, and legend. Then ask yourself a plain question, is the image comparing categories, showing change over time, or presenting several measures side by side?

Turn that answer into a short overview. For a bar chart comparing transport choices, the main idea might be the number of people using each option. For a line chart, it may be how a measure changed over several years. You do not need an impressive sentence. You need a correct subject that gives the rest of your answer a direction.

The 25-second preparation window is short, so write keywords rather than complete sentences. Note the topic, one useful high or low point, and one relationship you may want to explain. This leaves you with a small outline instead of a crowded page of figures. Pearson’s own task guidance also recommends identifying the main idea and organizing important details before speaking.

02 Choose one comparison that explains the main point

A chart with ten values does not require ten numbers in your response. Pick two or three details that help explain its main point. Useful choices include the highest and lowest categories, the widest gap, a clear contrast between two groups, or one figure that stands out from the rest.

Imagine a practice bar chart comparing three ways of commuting. Public transport has the highest count, cycling the lowest, and cars fall between them. A clear answer can state that comparison and add one accurate value as evidence. If the chart also shows several years, describe the overall pattern instead of listing every value in every year.

Numbers work best when you explain how they relate. Listing 42, 35, and 18 leaves the listener to work out the comparison. Saying that public transport is the most common option and has substantially more users than cycling gives those figures a purpose. Phrases such as higher than, while, compared with, and account for help connect information without requiring advanced vocabulary.

Check the units and legend before you speak. Make sure the horizontal axis shows categories or years, and confirm which colour or symbol belongs to each group. If an exact value is difficult to recall, use a careful approximation such as about or just over, then focus on the relationship you can describe accurately. A wrong unit or direction can change the whole comparison.

03 Describe the trend, then bring the answer to a close

For a line chart or a chart with a time axis, look at the broad direction first. Does the measure rise, fall, stay fairly stable, or rise before dropping? Then choose one clear turning point or value to support your summary. This is usually easier to follow than naming every point along the line.

Tables can be handled the same way. State the subject, describe the most useful difference, and add a shared pattern if one is visible. With a map, diagram, or photograph, adapt the method by naming the main subject, selecting a few important parts, and explaining how they connect. The order stays useful across chart types, overview, key relationship, supporting detail.

In the 40-second response, move from the general idea to evidence and finish with a brief summary. Think of it as a speaking route, not a script with a required number of sentences. Some charts need more time for a comparison; others are explained by one clear trend. A simple structure keeps you from circling around minor labels when the main pattern is already visible.

After practising, record your answer and replay it with three questions in mind. Did you identify the chart’s subject? Do your chosen figures support what you said? Did your sentences connect without long breaks? Then compare the response with the image and check the values, units, direction, and legend. Sometimes the missing skill is not more vocabulary; it is a better choice of details during preparation.

I like to treat each attempt as three small actions, look, describe, and review. YoushowPTE brings PTE task practice, AI feedback for speaking and writing, mock tests, and learning records together, so you can move from a Describe Image attempt to a focused review. Try a prompt on the YoushowPTE website, then use your recording and practice feedback to notice whether you missed a comparison, trend, or unit. Platform feedback supports preparation; the official PTE result comes through Pearson’s test process.

A busy chart does not need a busy answer. Find its main idea, choose the relationship that best explains it, and support your description with a detail you can state accurately. Next time the timer starts, jot down three cues, topic, comparison, and trend. Once those are clear, the chart has a much easier story to tell.
