Choose two signs to see the pairing.
What zodiac compatibility measures
This tool compares Sun signs by element—fire, earth, air and water—and modality—cardinal, fixed and mutable. Supporting elements often flow easily, identical elements share instincts, and contrasting styles can create productive tension.
What it cannot tell you
A Sun-sign pairing is one layer, not a verdict. Moon, Venus, Mars, Rising signs, communication and lived choices all matter. Use the score as a conversation starter rather than a prediction.
