Swiss Style is a graphic design approach that grew popular after the Second World War. It is also called the International Typographic Style. It is known for clear grids, carefully aligned layouts, simple shapes, and typography that is easy to read.
Imagine a poster where each piece has a clear place and the most important information is easy to find. The design can feel orderly without needing lots of decoration.
Swiss Style is a source of ideas, not a fixed recipe. A grid can help organize a page, but a designer still needs to choose what deserves attention.
