About the Venn Diagram Maker
Venn Diagram Maker draws a Venn diagram from your own lists. Choose two or three sets, name each set and type its items, one per line or separated by commas, and the page works out which items belong to only one set and which are shared, writes them into the right parts of the circles and counts each region. Names are matched without regard to capital letters, so Cat and cat are one item. Download the picture as a PNG for slides and worksheets or as an SVG for editing, and copy the list of regions as text.

- 5Download the PNG or SVG, or copy the regions.
What the regions mean
With two sets, A and B, there are three regions: only A, only B and both A and B (the intersection). With three sets there are seven: three for items in a single set, three for items in exactly two sets and one in the middle for items in all three. Each item sits in exactly one region, so the counts add up to the size of the union.
Ideas for using it
Venn diagrams help you compare and organise information in many subjects, from comparing two books to sorting numbers by their properties.
- Compare two characters, cities or products
- Sort numbers: even, multiples of 3, greater than 10
- Find common skills across three job roles
- Plan a survey: which people like which foods
Tips for a clear diagram
Keep names short, because long names are cut off in the title. Use one or two words per item; long items are shortened inside the circles but shown in full in the list. For a worksheet, leave a set empty and ask students to fill in the circles.

Frequently asked questions
What is a Venn diagram?
A drawing with overlapping circles that shows what several groups have in common and what is different. The overlap holds the items that belong to both.
How do I use it?
Type the items of each set. The page compares the lists for you and places each item in the correct region.
How many sets can I use?
Two or three. Four sets need other shapes, and diagrams with more sets are hard to read.
Does capitalisation matter?
No. Apple and apple are treated as the same item, and the first spelling is shown.
What if there are many items?
The circles show the first few items of each region and a +N more line for the rest. The full list of every region is written below the diagram.
Can I use it for school?
Yes. Teachers use Venn diagrams to compare characters, numbers, shapes and ideas. Download the picture and add it to a worksheet.
Can I download a transparent image?
The PNG has a white background. Download the SVG for an editable drawing you can colour.
Can I use it for numbers and words together?
Yes. Every item is treated as text, so words, numbers and short phrases all work. Numbers such as 1 and 1.0 are different items because they are written differently.
What is the union and the intersection?
The union is every item that appears in at least one set. The intersection is the items found in all of the sets, which for two sets is the overlap in the middle.
Is my data uploaded?
No. Everything is drawn in your browser.
