What is a Venn diagram?

A Venn diagram shows how groups overlap. Each group, or set, is a circle, and where circles cross you put the things that belong to more than one set. Two circles give three areas: only the first set, only the second, and both. Three circles give seven, with the middle area for things all three sets share. Teachers use them to compare stories or animals, analysts to compare customer lists, and anyone to show what two options have in common.

Tool description

Pick two or three sets, give each a name, and list its items, one per line. You don't have to work out the overlaps yourself: an item you list in more than one set goes into the area those sets share. The diagram updates as you type, with the items in one text size, as large as the fullest area allows. Add a title, pick a color for each circle and the background, and download the diagram as PNG, JPG, WebP, or SVG. Leave the items empty to get a blank Venn diagram to print and fill in by hand.

Features

  • Two-circle and three-circle Venn diagrams
  • Items sorted into the right area automatically, ignoring capital letters and extra spaces
  • Set names above the circles and an optional title
  • A color for each set and for the background
  • Text that wraps and shrinks to fit, with a "+N more" line when an area is full
  • PNG, JPG, and WebP downloads at twice the preview's size, or SVG for any size
  • Runs in your browser

Tips

  • To compare two lists, such as email addresses or product codes, paste one into each set and see what they share in the middle.
  • The circles are all the same size. They show which items overlap, not how big each set is.
  • Choose SVG to edit the diagram later in Inkscape, Illustrator, or Figma, or to keep it sharp at any size in a document.
  • For a worksheet, leave the items empty and print the downloaded image.
