How Zodiac Compatibility Works

Astrology compatibility is rooted in the elements, modalities, and planetary rulers of each sign. Fire signs (Aries, Leo, Sagittarius) thrive with fellow fire and air signs, while earth signs (Taurus, Virgo, Capricorn) find grounding with water and earth signs. But every pairing has hidden strengths — our compatibility calculator considers the full picture.
