Begin with both individual bodygraphs
Each person remains their own design inside a relationship. Create the two natal bodygraphs first, then use the connection chart to see what changes when those patterns meet.

What the connection chart reveals
Shared definition
See the centers and channels each person brings consistently into the relationship, along with the definition that appears when both bodygraphs meet.
Attraction and activation
Electromagnetic connections show gates that complete a channel together, often describing chemistry, movement, and themes that become stronger in one another’s presence.
Ease, pressure, and compromise
Companionship, dominance, and compromise patterns help explain where two designs feel familiar, where one person leads the energy, and where friction may require awareness.
Frequently asked questions
Human Design compatibility questions
What is a Human Design compatibility chart?
A Human Design compatibility chart, also called a connection chart, places two bodygraphs together to show the centers, gates, and channels each person brings and the energetic patterns created between them.
What birth information do we need?
You need the birth date, exact local birth time, and birthplace for both people. Accurate times produce the most reliable gates, lines, and connection mechanics.
What do electromagnetic connections mean?
An electromagnetic connection happens when each person carries one gate of the same channel. Together the two gates complete that channel, creating a theme that becomes active in the relationship.
Does compatibility tell us whether a relationship will work?
No chart can decide the outcome of a relationship. The connection chart describes recurring energetic dynamics so both people can recognize attraction, ease, pressure, and differences more clearly.
