Compatibility
Sign compatibility
See the dynamic between two signs clearly. Pick your pair.
Sign compatibility is the rough draft of relationship astrology — useful as an opening, never the final word. The pairings here read each combination across four dimensions: overall, love, communication, friendship. Element compatibility (fire+air, earth+water as natural pairings) sets the floor; modality (cardinal / fixed / mutable) fills in the dynamic.
What the score doesn't tell you: a "challenging" pairing can be the most growth-producing one. Stable relationships at any score depend on awareness, not on automatic flow. For a deeper read, calculate full synastry with the Synastry tool — Moon-Moon contacts, Venus-Mars chemistry, Saturn oppositions all show up there in a way no sign-only reading can.
