Frequently asked questions

How is zodiac compatibility calculated?

Traditional astrology looks at the angle between two signs on the zodiac wheel. Signs of the same element (a trine, 120° apart) are considered the most harmonious, followed by complementary elements (a sextile, 60° apart). Signs 90° apart (a square) are considered the most challenging.

Which zodiac signs are most compatible?

Signs of the same element tend to score highest: fire signs (Aries, Leo, Sagittarius), earth signs (Taurus, Virgo, Capricorn), air signs (Gemini, Libra, Aquarius) and water signs (Cancer, Scorpio, Pisces).

Can incompatible signs have a good relationship?

Yes. Sun-sign compatibility is a fun, very broad guide. Real relationships depend on personality, values and communication, and astrologers also look at full birth charts rather than sun signs alone.
