How we match signs

The three keys to compatibility

Element

Fire, earth, air or water: the basic temperament. Same and complementary elements connect most easily.

Modality

Cardinal, fixed or mutable: how each sign uses energy, which shapes how you share decisions and change.

Polarity

Same sign, opposite sign or neighbours. Opposites often feel magnetic and balancing.

Real compatibility lives across the whole chart. Compare your Moon signs for emotional rhythm and your Rising signs for how you approach life together.

Beyond Sun signs

Sun signs give a quick first impression of a match, but astrologers compare whole charts to understand a relationship. This is called synastry.

The Moon shows emotional rhythm, Venus shows how you love and Mars shows how you act on desire. Comparing these placements often explains chemistry that Sun signs alone cannot.

Zodiac compatibility: your questions answered

How does zodiac compatibility work?

This checker looks at element, modality and polarity, the classic foundations of Sun sign compatibility. For a deeper reading, compare Moon, Venus and Mars signs too.

Which zodiac signs are most compatible?

Signs of the same element often connect easily, as do fire with air and earth with water. Opposite signs can also be strongly attracted.

Can incompatible signs make a good couple?

Yes. Sun signs are only one part of the picture, and challenging matches often grow the most. Communication and shared values matter far more.
