Is synastry or a composite chart better for marriage compatibility?
Synastry compares two people’s planetary placements; a composite chart is a symbolic chart commonly constructed from midpoints between their placements. They ask different questions rather than competing to deliver a final marriage score. Synastry explores the interaction between individuals, while a composite is often read as a picture of the relationship.

Neither method replaces knowing the people involved. A supportive synastry aspect can coexist with a difficult pattern in daily life, and a composite interpretation is not an independent forecast. Zenith’s web calculator currently calculates individual natal charts, not composite charts or a full synastry report. You can begin by understanding each natal chart before interpreting a comparison.
A question to take with you.
Try: “Am I asking how we affect each other, or what themes we create together?” Choosing the question first makes the difference between these methods clearer.
Try this.
- Calculate each individual natal chart with verified details where possible.
- Use the actual relationship to evaluate whether a comparison feels relevant.
