The regions of a 3-set Venn diagram
Three circles make seven regions: three for items in just one set, three for items shared by exactly two sets, and one in the centre for items in all three. It’s the most common Venn diagram in maths exams and the best size for comparing three options.
With three sets there are 2³ = 8 regions including the outside. Fill them from the centre outwards: A ∩ B ∩ C first, then the three “exactly two” regions, then the “only” regions. That order avoids double counting (the calculator page shows why).
In the editor’s Text tab every region is listed with its name and set notation, so you always know where an item belongs. Comparing real lists (class rosters, survey answers, gene IDs)? Paste one list per set into the From lists tab and every item is sorted into the right region, with counts and percentages if you want them.

Questions people ask
What is a triple Venn diagram?
A triple Venn diagram is a three-circle Venn diagram. Each circle is a set and the seven regions inside show every combination of membership, with the very centre holding what all three have in common.
How many regions are in a 3 circle Venn diagram?
Seven inside the circles, or eight if you count the region outside all three circles (inside the universal set).
How do I label the middle of a 3 circle Venn diagram?
Click the centre region, where all three circles overlap, and type. In set notation it is A ∩ B ∩ C.
