Zodiac Compatibility
Compatibility for every zodiac pairing — love, communication, friction and long-term potential, each with a compatibility score grounded in real astrology. Pick a sign to see all its matches, then go beyond sun signs to your true chart-based compatibility.
How zodiac compatibility works
Astrological compatibility starts with two things every sign carries: its element and its quality. The four elements — fire, earth, air and water — describe how a sign is fuelled: fire runs on passion and action, earth on steadiness and the practical, air on ideas and connection, water on emotion and intuition. Signs of the same element understand each other instinctively; complementary elements (fire with air, earth with water) feed one another; and opposite temperaments (fire with water, earth with air) attract strongly but have the most to translate.
The three qualities — cardinal, fixed and mutable — describe how a sign moves. Cardinal signs initiate, fixed signs sustain, and mutable signs adapt. Two initiators build momentum but jostle to lead; two fixed signs are loyal but stubborn; a cardinal-and-mutable pair often divides the work gracefully. Put element and quality together and you have the backbone of any compatibility reading.
The elements in love
Fire and air are the classic live-wire match — air fans the flame, fire gives air's ideas life, and neither is ever bored. Earth and water are the great nurturers — earth gives water form and security, water gives earth feeling and depth. Same-element pairings feel like home, for better and worse: the resonance is easy, but there is no opposite energy to balance a shared blind spot. And the "difficult" pairings — fire with water, earth with air — are often the most magnetic precisely because each partner works nothing like the other.
None of this is destiny. Every element pairing can flourish or founder; the elements simply tell you where the natural ease is and where the growth lives.
Beyond sun signs
Sun-sign compatibility is a genuinely useful starting point — but the Sun is one of many moving parts. Real compatibility lives in synastry: the aspects between two complete birth charts. It is your Moon meeting their Venus, your Mars landing in their houses, the trines that flow and the squares that spark. Two people of the "wrong" signs can fit beautifully when the rest of the chart agrees, and two "perfect" signs can struggle when it doesn't.
That is why the scores below are a first word, not the last. To read how you actually fit, calculate both birth charts and let Sigastra interpret the real synastry between them.

Frequently asked
Which zodiac signs are most compatible?+
Traditionally, signs share the easiest chemistry with others of the same element or a complementary one — fire with air, earth with water. But every pairing can work; the elements only point to where the natural ease is.
Is sun-sign compatibility accurate?+
It is a useful starting point that captures the broad temperament of a match, but it describes only one part of each person. Real compatibility comes from the synastry between two full birth charts.
How is the compatibility score calculated?+
Each pairing's score is derived deterministically from the two signs' elements, qualities and traditional affinities — the same astrology, applied consistently across all 78 pairings.
How do I get my real compatibility?+
Calculate both birth charts and read the synastry between them. Sigastra's personal compatibility reading interprets your actual inter-chart aspects for a tailored verdict.
