Free Venn Diagram Maker

A Venn diagram uses overlapping circles to show the relationships between two or more sets. Each circle represents one group of things; the overlapping regions show what the groups have in common, while the outer parts show what makes each group unique. The diagram is named after the English logician John Venn, who popularized it in the 1880s.

Because it turns an abstract comparison into a picture you can read at a glance, the Venn diagram has become one of the most widely used thinking tools in classrooms and workplaces alike — for comparing characters in an essay, positioning products against competitors, planning features, or teaching set theory and probability.

When to use 2 circles vs. 3 circles

A 2-circle Venn diagram is the classic compare-and-contrast layout: two subjects, their differences on the outside, their similarities in the middle. Use it when the question is "how are these two things alike and different?"

A 3-circle Venn diagram adds a third set and creates seven distinct regions, including a center shared by all three. It's ideal for comparing three options, mapping skills against roles, or finding the sweet spot where three criteria meet — the classic "passion / skill / market" framing, for example.
