Posters are one of the most common multimodal texts we study in IB English. They appear in advertising, awareness campaigns, political messaging, film promotion, and many other areas. Because they combine text and image, posters are designed to persuade, inform, provoke, or inspire. In IB assessments such as Paper 1 and the Individual Oral, you are expected to analyse how these elements work together to create meaning.
Analysing a poster means going beyond surface impressions. You need to consider how it looks, how it reads, and what message it is trying to communicate. Every element has been chosen for a reason: the image, the layout, the colour palette, the font, and the specific wording. Posters are constructed with care, aiming to influence the viewer’s thinking, behaviour, or emotional response.
A strong poster usually:
• Has a clear purpose (such as promoting a product, encouraging a behaviour, or raising awareness)
• Targets a specific audience (such as children, voters, or consumers)
• Uses eye-catching visuals (including colour, composition, and symbolism)
• Includes short, persuasive, and memorable text
• Communicates its message quickly and clearly
Understanding context is also important. A political poster from a conflict zone will work very differently to a health campaign aimed at teenagers. The social and cultural background helps shape both the poster’s message and how audiences interpret it.
When analysing a poster, it helps to follow a structured approach such as ITSLIDETH. This allows you to comment on both the textual and visual features in an organised way.
• Information: Who created the poster? When and where was it made? What is its purpose?
• Tone: What mood or attitude is being communicated? Is it serious, humorous, emotional, or ironic?
• Structure: How is the layout arranged? Where is your eye drawn first?
• Language: What kinds of words are used? Are there slogans, statistics, or rhetorical questions?
• Image: What does the imagery show or suggest? What symbolism is used?
• Devices: Are there any persuasive techniques at work, such as repetition, contrast, or exaggeration?
• Evaluation: How successful is the poster in achieving its goal?
• Thesis: What is your overall interpretation of the poster’s message and method?
Posters help build your ability to analyse how meaning is shaped through a combination of text and visuals. They also support your development as a critical thinker and reader of media. Many posters deal with global issues, including the environment, human rights, gender, and consumerism, which makes them highly relevant to IB themes.
By learning to unpack how posters communicate, you strengthen your ability to interpret the media that surrounds us. These are skills you will use throughout the IB course and beyond.
Hierarchy: The visual arrangement of elements in order of importance, guiding the viewer’s attention.
White space (or negative space): Empty space around design elements, used to create focus or avoid clutter.
Alignment: The arrangement of elements in a straight line or according to a grid, which affects balance and readability.
Grid layout: A structured layout system that helps organise content spatially, often used in modern poster design.
Margins and gutters: The borders and spaces between elements; used to separate information clearly.
Balance: The distribution of visual weight within the poster, which may be symmetrical or asymmetrical.
Visual flow: The path the viewer’s eye naturally takes across the poster, often starting with the focal point.
Typeface: The design of lettering (e.g. serif, sans-serif, decorative) that communicates tone and function.
Kerning: The spacing between individual characters in a word.
Leading: The spacing between lines of text.
Tracking: Uniform spacing across all letters in a word or sentence.
Vector graphics: Clean, scalable images often used in poster illustrations (as opposed to pixel-based photos).
Iconography: The use of simple, recognisable symbols or icons to convey ideas quickly.
Silhouette: A solid outline or shape used to convey form with minimal detail.
Posterisation: A visual effect that reduces the number of tones in an image, often used for a dramatic, stylised look (e.g. Shepard Fairey’s Obama “Hope” poster).
Complementary colours: Colours opposite each other on the colour wheel, used to create strong contrast.
Analogous colours: Colours next to each other on the colour wheel, used for harmony and cohesion.
Saturation: The intensity or purity of a colour; high saturation grabs attention, while low saturation can suggest calm or sadness.
Colour temperature: The emotional association of colours — warm (red, orange, yellow) versus cool (blue, green, purple).
