Apply layout, hierarchy and data visualisation to design effective posters and information graphics that communicate clearly

What this dot point is asking

This dot point asks you to apply layout, hierarchy and data visualisation to design effective posters and information graphics. Posters must grab attention and communicate a message quickly, often from a distance; information graphics (infographics) must turn complex information or data into something easy to understand. You should know how to make a poster stand out and read clearly, how to build a strong visual hierarchy, and how to visualise data simply and honestly. This dot point applies the principles of visual communication and composition to two of the most common real design tasks.

The answer

What makes a poster work

A poster has to do two things in seconds: stop the viewer and deliver the message. It must grab attention, usually through a bold focal point (a striking image or a large headline) and strong contrast, so it competes with everything around it. Then it must communicate clearly, with the key information easy to read, even from a distance. A useful way to think about persuasive posters is attention, interest, desire, action (the AIDA idea): catch the eye, build interest, create desire, and prompt an action such as attending or buying.

Visual hierarchy in posters

Hierarchy is the heart of poster design. The viewer should read the information in order of importance: the main message or event name first (largest, boldest), then the essential details such as date, time and place, then supporting information last (smallest). Hierarchy is created with size, weight, colour, position and space. A poster with no hierarchy, where everything is the same size, forces the viewer to work too hard and usually fails.

Clarity and restraint

Effective posters and information design include only what is needed. Cluttered designs with too much text and too many elements bury the message. Restraint, legible type, a clear layout aligned to a grid, and generous white space let the message come through. This is where the clean, ordered thinking of Swiss Style is especially valuable: clarity above decoration.

Information design and infographics

Information design turns complex information into something clear and quick to understand. An infographic combines charts, icons, images and short text to communicate facts and data visually. Infographics work because visuals are processed faster than text, patterns in data become visible, and the result is more engaging and memorable. Good information design organises content logically, guides the reader through it, and uses visuals to do the explaining.

Data visualisation, done honestly

Data visualisation presents numbers as charts and graphics so comparisons and trends are easy to see. The skill is choosing the right chart for the data (a bar chart to compare amounts, a line chart for change over time, a pie chart for parts of a whole) and keeping it simple and clear. Crucially, data must be shown honestly: misleading scales, distorted proportions or cherry-picked figures break the trust that information design depends on. Clear, truthful visuals are the goal.

Examples in context

Example 1. A public health infographic. A health campaign turns statistics into a clear infographic with bold numbers, simple icons and a single bar chart, so the public grasps the key facts in seconds. It shows information design making data faster to understand and more memorable than a page of text would be.

Example 2. An event poster from a distance. A well-designed gig poster reads at three levels: the band name catches the eye across the street, the date and venue are clear as you approach, and the small print is there when you stand close. This layered hierarchy shows a poster designed for how people actually encounter it.

Try this

• Cue. Find a poster and identify its hierarchy: what you read first, second and third. Explain how size, colour and position create that order, and whether the most important information truly stands out.

• Cue. Take a few simple statistics and sketch an infographic for them, choosing a suitable chart and one bold headline figure. Check that your chart is clear and represents the numbers honestly.

• Cue. Redesign a cluttered notice as a clear poster: choose one focal point, build a three-level hierarchy, cut unnecessary content, and add white space. Explain how the message now reads more quickly.
