Genogram maker / Relationship lines

Genogram relationship lines

A genogram uses two kinds of lines. Structural lines show how people are related: partners, parents and children. Emotional relationship lines, drawn straight between two people, show what the relationship feels like.

Read a line by its parts

Emotional lines are built from a small grammar. More parallel lines means more closeness, up to fusion. A zigzag adds conflict. A break means the relationship has been cut off. An arrowhead means the relationship runs in one direction: someone is the focus of attention, or someone is being harmed.

Pick a relationship and watch how the line between a mother and son changes.

All emotional relationship symbols

LineRelationshipWhat it means
CloseTwo parallel lines: a warm, supportive bond.
Fused / very closeThree parallel lines: enmeshed, boundaries blurred.
DistantDashed line: little contact or emotional warmth.
ConflictualZigzag line: ongoing hostility or conflict.
Close–conflictualZigzag between two lines: close but hostile.
Fused–conflictualZigzag within three lines: enmeshed and hostile.
Cutoff / estrangedLine broken by two bars: no contact.
Focused onArrow: one person is the focus of the other’s attention or worry.
Physical abuseZigzag with an arrow pointing at the person harmed.
Emotional abuseDashed zigzag with an arrow toward the person harmed.
Sexual abuseZigzag beside a solid line, arrow toward the person harmed.
NeglectDotted line with an arrow toward the person neglected.

Structural lines

Partner and parent–child lines follow separate rules, covered in the genogram symbols key: a solid partner line for marriage, dashed for living together, one slash for separation and two for divorce; a solid line to a biological child, dashed for adoption and dotted for foster care.

Using relationship lines well

  • Look for triangles. Two people in conflict and a third close to one of them is the classic Bowen triangle. It jumps out once the lines are drawn.
  • Draw what the client reports, and date it. Relationships change; a note like “cut off since 2019” is more useful than the line alone.
  • Colour helps, but shouldn’t be required. GenogramCraft colours conflict red and closeness green, but every line type also has its own shape, so a black-and-white print still reads correctly.
  • Keep charts readable. If lines start crossing everywhere, draw a second genogram focused on one branch or one relationship pattern.

Frequently asked questions

What do the zigzag lines on a genogram mean?

A zigzag line between two people means the relationship is conflictual or hostile. A zigzag enclosed by two parallel lines means close–conflictual (intense but hostile), and within three lines it means fused–conflictual.

What does a line with two short bars mean?

A line broken by two short perpendicular bars is a cutoff: the two people are estranged and have no contact. Cutoffs are a key concept in Bowen family systems theory.

How do you show abuse on a genogram?

Abuse lines combine a zigzag with an arrow pointing to the person harmed. Physical abuse uses a solid zigzag, emotional abuse a dashed zigzag, and sexual abuse a zigzag alongside a solid line. Record only what has been disclosed or substantiated, and follow your agency’s guidance on what goes in a shared record.

What is the difference between close and fused?

Two parallel lines mean close: warm and supportive with healthy boundaries. Three lines mean fused or enmeshed: so close that individual boundaries are blurred, which Bowen theory links to lower differentiation of self.
