What is the middle of a Venn diagram called?

The overlapping area is called the intersection. It contains the elements that belong to all of the sets being compared.

Can a Venn diagram compare three things?

Yes. A three-set Venn diagram has three circles, three pairwise overlaps and a central area shared by all three. In this template, add a third set branch and a branch for each overlap.

Venn Diagram Template

By RP Hobbyist · Updated October 2026

A Venn diagram compares sets by showing what each has on its own and what they have in common. It is named after the English logician John Venn, who introduced it in 1880. Two overlapping circles are the classic form: the outer parts hold what is unique to each item, and the overlap holds what they share.

This template turns the diagram into an editable map with three branches: Set A, Set B and their Intersection. Listing items as nodes, instead of squeezing text into overlapping circles, leaves room for as many points as you need and keeps the comparison readable when you export it.

When to use a Venn Diagram

Comparing two products, tools, ideas or candidates
Compare-and-contrast exercises in school and study notes
Finding common ground between two teams, audiences or proposals
Checking where two customer segments overlap

What goes in each branch

Set A: Everything that is true of the first item but not the second. Rename the branch to the item's name.
Set B: Everything that is true of the second item but not the first.
Intersection: Characteristics both items share. This is often the most useful branch for finding common ground.

Example: Comparing working from home with working in an office

Home only: no commute, flexible hours, fewer interruptions
Office only: face-to-face collaboration, a clear separation from home life
Shared: the same tasks, deadlines and team goals

Tips

Compare items at the same level, for example two tools rather than a tool and a company.
Check each point: if it applies to both items, move it to the Intersection.
For three items, add a Set C branch and a branch for each pair's overlap.
Finish with a conclusion node that says what the comparison means for your decision.
