How sign compatibility works

Sun-sign compatibility is the simplest way astrology compares two people: take both zodiac signs and look at how they relate around the wheel. It is also the most limited one. Your Sun sign is one placement out of dozens; the Moon, Venus, Mars, the Ascendant and the aspects between two whole charts say far more about how two people actually feel together. Treat this page as a starting point for conversation and self-reflection, not as a verdict on any relationship.

The logic behind sign compatibility is geometric. Signs of the same element — fire, earth, air or water — sit 120° apart (a trine) and tend to understand each other's pace and values. Fire and air feed each other, as do earth and water; these complementary pairs sit 60° apart (a sextile) or directly opposite (an opposition). Signs 90° apart (a square) share a modality — both cardinal, fixed or mutable — but belong to elements that work differently, which brings friction and momentum. Signs 150° apart (a quincunx) or side by side (30°) share neither, so they need more conscious translation.

The chart below turns those two ingredients into a transparent sign-level harmony number from 0 to 100: points for how the elements relate plus points for how the modalities relate, with the exact breakdown on every pair page. A lower number does not mean a pair can't work — squares and oppositions often describe strong attraction and growth — and a high number guarantees nothing. For a real comparison, synastry looks at both birth charts in full, which is what our matching does.

How the elements get along

Same element: easy understanding — a shared basic temperament and pace.

Complementary elements (fire with air, earth with water): you feed and balance each other.

Contrasting elements: different needs and speeds — attraction is possible, understanding takes translation.
