How to Make a Venn Diagram Online (2 or 3 Circles)
List the items in each group and get a Venn diagram with the overlaps worked out for you — 2 or 3 circles, items or counts, proportional sizes. Free.
3 min read ·
To make a Venn diagram, open the Venn Diagram Maker, choose 2 circles or 3 circles, name each set, and list its members — one item per line. Anything that appears in two or three lists is placed in the overlap automatically. Choose whether the regions show The items, How many items or Count and items, and download the diagram.
Make a Venn diagram step by step
- Open the Venn Diagram Maker.
- Under Number of sets, choose 2 circles or 3 circles.
- Under Sets, give each set a name ("Cats", "Dogs") and list its items, one per line (or separated by commas).
- Under Options, choose In each region show: The items, How many items, or Count and items.
- Optionally tick Proportional circles to size them by their number of items.
- Check the table under the diagram, which lists every region and its items.
- Download a PNG, JPG or SVG.
Why list members instead of typing into regions?
In most Venn tools you type text into each overlapping region yourself — and it's easy to put an item in the wrong place. Here you just list what belongs to each group, and the overlaps are calculated. Matching ignores capital letters, so "Pizza" and "pizza" count as the same item.
Ideas for Venn diagrams
- Compare and contrast in school: two characters, two countries, two historical periods.
- Product comparisons: features of two or three products — what's shared, what's unique.
- Skills and roles: what a designer, a developer and a product manager each do, and where they overlap.
- Customer segments: people who bought A, B, or both.
- Survey answers: who chose which options.
- Planning: what you love, what you're good at, what pays — the classic career Venn.
Items, counts or both?
- The items — best for short lists and teaching, where seeing names matters.
- How many items — best for large lists (hundreds of customers or survey answers), where names would overflow.
- Count and items — counts as headlines with items underneath.
Proportional circles
With proportional sizing, each circle's area matches its number of items and each overlap matches how many items are shared — so a small overlap looks small. Exact proportions aren't always geometrically possible with three circles, but the layout gets as close as it can. Turn it off for equal circles, which are easier to fill with text.
Tips for clear diagrams
- Short item names fit better in small regions.
- Two or three sets — beyond three, Venn diagrams become hard to read.
- Use the table below the diagram when sharing exact membership in a report.
A worked example
Compare three streaming services' features: list each service's features under its name. The centre fills with what all three offer, the paired overlaps with what two share, and the outer parts with each service's unique selling points — a clear one-slide comparison, worked out without placing a single item by hand.

Frequently asked questions
Can I make a Venn diagram with four circles?
This tool supports two or three circles. For more groups, a table or an UpSet-style bar chart is clearer.
Why didn't two items match?
Spelling must match apart from capital letters — "colour" and "color" are different items.
Can I change the colours?
Yes — use the colour options in the style settings.
