Fire / Earth / Air / WaterHow compatibility works
Our methodology, brieflyA compatibility reading is not a verdict. We compute it from three signals first: elemental affinity (fire-air and earth-water rhyme; the cross-element pairs need more translation), modality balance (two cardinals make plans, two fixed dig in), and ruling-planet flavour (Venus-ruled signs cluster around aesthetic ease, Mars-ruled around drive). The matrix on this page colour-codes the first signal; the pair pages add the rest.
But a real reading depends on the whole chart — Moon, Venus, Mars, the houses, the angles. Two charts can share sun-sign tension and feel perfectly aligned at the Venus level, and vice versa. The synastry calculator computes the exact inter-chart aspects when you have both birth times. Sun-sign compatibility is the conversation starter; chart synastry is the conversation.
