Overview
What Is a Composite Chart?
The composite chart is created by calculating the midpoint between each pair of planets in two people's birth charts, creating a single chart that represents the relationship itself. Unlike synastry (which shows interaction), the composite reveals the relationship's character — its DNA. It answers: “What is this relationship about? Where is it going? What does it need to thrive?”

FAQ
Frequently Asked Questions
What is a composite chart in astrology?
A composite chart is a merged chart created from the midpoints of two individuals' birth charts. It represents the relationship itself as a unique entity, showing its strengths, challenges, and life path as a pair.
Should I use synastry or composite?
Both. Synastry is better for understanding the initial dynamic and chemistry between two people. The composite chart is more useful for understanding the long-term trajectory and purpose of the relationship. Most astrologers analyze both.
How is a composite chart calculated?
Each planet and point in the composite chart is calculated by finding the midpoint between the same planet in each individual's chart. For example, the composite Sun is the midpoint of Person A's Sun and Person B's Sun.
