Sign Compatibility: All 78 Astrological Pairings

Every possible sun-sign combination, analyzed by element, modality, aspect, and ruling planet. Sun-sign compatibility is the floor of compatibility, not the ceiling, but it is the right place to start. Pick a sign below to see all twelve of its pairings.

By Sign

Click your sun sign or your partner's to see all twelve compatibility pages for that sign.

How to Read These Pages

Each pairing analyzes four structural factors: the elemental mix (fire, earth, air, water), the modality mix (cardinal, fixed, mutable), the aspect between the two signs in the zodiac (conjunction, sextile, square, trine, opposition, semi-sextile, quincunx), and the relationship between the two ruling planets. These four factors give you the basic temperature of any pairing.

What they cannot tell you is whether you actually fit. That requires Moon-to-Moon, Venus-to-Mars, and house overlay analysis. Synastry is the practice of comparing two full charts, and it produces a much more accurate picture than sun-sign matching alone.

What ZODIA Does Differently

Generic compatibility tools treat the sun sign as the entire chart. ZODIA treats your full natal chart as the input and reads it against the current sky every morning. Calculate your free birth chart to see what you are actually working with, then start your 7-day free trial to receive personalized daily readings on WhatsApp.

ZODIA reads compatibility from the whole chart, grounded in traditional astrological technique. Sign-level matches follow the classical element and modality groupings; the real fit is judged from both complete charts, especially the Moon, Venus, and rising sign.
