Compatibility in astrology is not a score. Two charts compared side by side show where the contact is easy, where it is abrasive, and what each person tends to need that the other does not naturally offer. A high number tells you very little; the location of the friction tells you almost everything.

There are two standard ways to look. Synastry lays one chart over the other and reads the contacts between them, which shows how the two of you affect each other. A composite chart builds a third chart from the midpoints and reads the relationship itself as a single body with its own temperament.

The Moon, Venus and Mars carry most of the weight: the Moon for what feels safe, Venus for what feels valued, and Mars for how conflict and desire get expressed. A pairing that struggles on Mars but agrees on the Moon has a different problem than the reverse, and the two are not fixed the same way.
