Zodiac compatibility

Pick two signs and we’ll tell you how their energies tend to fit. With an honest warning: sun signs are the cover — the whole book is each person’s full chart.

Our real chemistry →

The serious comparison uses both complete charts: date, time and place for each of you.

What the sign can tell (and what it can’t)

Sun-sign compatibility rests on the elements: fire and air feed each other, earth and water nourish each other, and cross mixes ask for more translation. It’s a fine first glance — but two people are far more than their Suns: the Moon, Venus, Mars and the rising sign weigh as much or more in how you love and live together. That’s why our serious couple reading compares both full charts, degree by degree.

The serious version
Really curious? Express compatibility (€1.90) compares your two full charts, and the Couple pack (€6.90) includes the whole synastry with your real aspects.

Frequently asked questions

Is zodiac sign compatibility reliable?

Comparing only Sun signs is fun but very partial. Real compatibility between two people shows in the synastry, which compares both full charts, not just the Sun.

Which signs are most compatible?

By element there's usually good chemistry within the same element, and between fire and air or earth and water. But it's a general guide: it depends on the rest of the chart.

What's the difference between sign compatibility and synastry?

Sign compatibility looks at one piece, the Sun. Synastry crosses both full charts (Moon, Venus, Mars, rising signs, houses and aspects) and explains what unites you, where you clash and how to care for each other.

Is this calculator free?

Yes, sign compatibility is free and needs no sign-up. The serious reading of both full charts (Express compatibility and the Couple pack) is paid.
