Enneagram Tritype Complete Guide: How Three Centers Create Your Unique Personality Code

Beyond the basic nine types, Tritype identifies your dominant type in each of the three centers — Gut, Heart, and Head — to produce a richer, more precise personality profile. Developed by Katherine Fauvre Chestnut, this concept is the cornerstone of advanced Enneagram study.

What Is Tritype?

The nine Enneagram types are organized into three Centers:

Center	Types	Core Emotion
Gut (Body) Center	8, 9, 1	Anger
Heart Center	2, 3, 4	Shame
Head Center	5, 6, 7	Fear

Your Tritype is a combination of three numbers — one from each center.

Example: Tritype 479

From the Gut Center (8, 9, 1): 1
From the Heart Center (2, 3, 4): 4
From the Head Center (5, 6, 7): 7

Tritype Order: The first number listed is your primary type. 147, 471, and 714 share the same numbers but indicate different primary drives.
