Zodiac sign compatibility

How the compatibility model works

Traditional astrology reads compatibility through the four elements. Two signs of the same element run at a similar temperature and understand each other instinctively. Fire and air signs feed one another, as do earth and water. The more contrasting pairings, fire with water or air with earth, are cast as growth matches: more friction, but more to learn from each other. Modality, whether a sign is cardinal, fixed or mutable, adds a second layer, since two signs of the same modality can compete for the same role.

The percentages here are a light reference heuristic built from those traditions, not a prediction about any real relationship. Every pair page explains the reasoning so you can see where the number comes from.

Frequently asked questions

Which signs are most compatible?

Same-element pairs and the fire-air and earth-water combinations. Leo and Sagittarius, or Taurus and Cancer, are classic strong matches.

Do opposites attract in the zodiac?

They can. Contrasting element pairings need more effort but often balance each other well, since each sign brings what the other lacks.
