Genogram symbols and their meanings

This reference shows each symbol and line that Genogram Builder draws, together with its meaning in the standard genogram notation.

4 min readChecked 16 October 2026

Genogram Builder follows the notation described by McGoldrick, Gerson and Petry (2020). Every symbol in this reference is drawn by the editor’s own renderer, in the same form as in the key on the canvas. Of the 74 entries, 15 are conventions of Genogram Builder and are not part of the published notation. They include the dashed line to a step-child, the red zigzag for a non-consensual incident, the outlines for a temporary arrangement and for a highlight, and the couple statuses that the editor distinguishes beyond those of the book, such as an engagement, a legal separation or an annulment. Each of them is marked Genogram Builder convention, and if you use one in submitted work, you should state that it is an addition.

Other genogram programs sometimes draw the same facts in different ways. In this editor, an adoption is drawn as a solid and a dotted line in parallel, a household as a dotted outline and a non-binary person as an arched shape. A chart made with another program should therefore be read with that program’s own key.
