Designing with symbols — Design, 7–10 years
A simple picture or sign can give information quickly, even when there is little space or people speak different languages.
A picture with a job
A symbol is a small, planned sign that stands for an idea, action or place. A picture of a running person can mean “exit this way”, while a crossed-out cigarette can mean “do not smoke”. Good symbols are simple enough to recognise quickly, but specific enough not to be confused with another message.
Why symbols were needed
Words are useful, but they take time to read and may not be understood by everyone. In a noisy station, a dark road or an emergency, people need information at a glance. Designers developed signs to cross language barriers and guide people when there is no time for a long explanation.
Example: a hand-washing sign
A school wants visitors to find the sinks quickly. First, the designer chooses two hands under drops of water, because those shapes match the action. Next, they remove tiny details and place the picture beside an arrow. Finally, they show it to someone who has not seen the plan. If that person finds the sink, the symbol is doing its job.
The trap: clear to the maker
A reasonable mistake is to draw every detail, because details feel helpful to the person who knows the object already. But a crowded symbol takes longer to read and can lose its main meaning. The opposite mistake is making it so simple that it could mean several things. Testing it with a stranger helps reveal both problems.
Where it appears
Symbols guide people in airports, parks, toilets, hospitals and road systems. App icons use tiny pictures so you can recognise a camera, map or message without reading a label. Designers also use warning symbols on packaging and machines, where a quick glance may prevent a mistake.
