Zodiac Compatibility
Zodiac compatibility measures how two sun signs interact in love and friendship, based on their elements (fire, earth, air, water) and modalities (cardinal, fixed, mutable). Comparing two signs shows where they naturally click and where the differences need work.

Frequently asked questions
How is the zodiac compatibility score calculated?
Each zodiac compatibility score comes from Keiro's sun-sign calculator, which weighs the two signs' elements and modalities. The result is a 0–100 score with a verdict of compatible, balanced, or growth-oriented — applied consistently to every sign pairing.
Which zodiac signs are most compatible?
Signs that share an element, or sit in harmonious elements like fire and air, generally score highest, while square aspects take more effort. Pick your sign and your partner's above to read the exact compatibility score and the reasons behind it.
