Have you ever wondered why some relationships feel effortless while others are a constant uphill battle? In astrology, the answer often lies in the elements, aspects, and planetary rulers that define each zodiac sign.

Fire signs (Aries, Leo, Sagittarius) thrive with Air signs (Gemini, Libra, Aquarius), feeding each other's energy. Earth signs (Taurus, Virgo, Capricorn) find grounding with Water signs (Cancer, Scorpio, Pisces), creating stability and emotional depth. But compatibility goes beyond elements — the angle between two signs on the zodiac wheel, their shared or clashing modalities, and their ruling planets all play a role.

Our compatibility tool draws on these classical astrological principles to show you how your sign connects with every other sign across three dimensions: Romance, Sex, and Communication. Select your zodiac sign below to discover your scores and a brief description for each pairing.

Note: Sun sign compatibility offers a general overview. For a complete picture of relationship dynamics, a full synastry chart analysis — comparing both partners' complete birth charts — provides much deeper insight.
