What are the Human Design centers?

The nine shapes in your bodygraph are the centers. Colored in means defined: that energy works the same way for your whole life. White means open: you take that energy in from the people and places around you and amplify it. Open centers are where most of what you assumed was your personality turns out to be borrowed.

Head · Ajna · Throat · G · Heart · Sacral · Spleen · Solar Plexus · Root

The short answer

The nine centers are the shapes in your Human Design bodygraph, and each one governs a different kind of energy: mental pressure, thinking, communication, identity, willpower, life force, intuition, emotions, and drive. Every center is either defined or open.

A defined center is colored in. That energy is consistent and works the same way for your whole life. An open center is white. You take that energy in from the people and places around you and amplify it, which is where most conditioning happens and where a great deal of what you assumed was your personality turns out to be borrowed.

What this page covers

Every percentage below is measured across the charts we calculate. The Throat is the most commonly defined center at 73%, and the Head is the most commonly open at 74%, which is why so many people carry mental pressure that was never theirs to begin with.

The Ajna Center

Certainty and how you think

The Ajna turns mental pressure into concepts, opinions, and ways of understanding. It is how you process, not what is true.

Defined

Defined, you have a fixed way of thinking that others come to rely on. You are not designed to be argued out of your own certainty.

Open

Open, you borrow certainty from whoever is present, which lets you hold several views at once. That is flexibility, though it feels like confusion when you try to be as sure as everyone around you.

The Throat Center

Communication and manifestation

The Throat is where energy becomes speech and action. Everything in the chart is trying to get here.

Defined

Defined, you have a consistent voice and a reliable way of expressing yourself, and it is the most commonly defined center of all.

Open

Open, your voice adapts to the room. Speaking to be noticed tends to backfire; speaking when you are asked tends to land, and the difference is dramatic once you feel it.

04

The G Center

Identity, direction, and love

The G center holds your sense of who you are, where you are going, and how you love.

Defined

Defined, you carry a steady sense of self and direction that does not depend on where you are.

Open

Open, your sense of identity and direction shifts with your environment and the people in it. This is why place matters so much for you, and why the right room can change how you feel about your whole life.

The Heart Center

Willpower, worth, and resources

The Heart, also called the Ego or Will center, governs willpower, self-worth, and material resources. It is the smallest center and the hardest to fake.

Defined

Defined, you have willpower available in cycles and can make promises you are actually able to keep.

Open

Open, you absorb pressure to prove your worth, and it is the most common place people over-promise. You have nothing to prove, and the promises made to prove something are the ones that cost the most.

The Sacral Center

Life force and work energy

The Sacral is the engine. It generates the energy for work, and its response is the clearest yes and no in the whole system.

Defined

Defined, you are a Generator or Manifesting Generator, with renewable energy for work that genuinely lights you up.

Open

Open, you amplify other people's energy, which means you can work like a machine and then crash. Knowing when enough is enough, before you are empty, is the practice that changes everything.

07

The Splenic Center

Intuition, health, and fear

The Spleen is your survival intelligence: instinct, health, timing, and fear. It speaks once, quietly, in the moment.

Defined

Defined, you have a consistent body-level knowing about what is healthy and what is off, and it is rarely loud.

Open

Open, you pick up other people's fears and hold onto things past their time, including relationships and jobs. Not every fear you feel started with you.

08
Defined in 47.4% of charts we calculate

The Solar Plexus Center

Emotions and emotional clarity

The Solar Plexus runs the emotional wave. When it is defined it also becomes your decision-making authority, and there is no truth in the moment.

Defined

Defined, you move through a wave of highs and lows that is yours, and clarity comes with time rather than in the moment.

Open

Open, you take in the emotional weather of the room and amplify it. A great deal of what you feel is not yours, and it fades when you leave. Learning that is often the single biggest relief in a reading.

09
Defined in 53.3% of charts we calculate

The Root Center

Pressure, stress, and drive

The Root is a pressure center that fuels action and adaptation. It is the pressure to get things done.

Defined

Defined, you generate your own pressure in pulses, and you can handle stress in a way that is consistent for you.

Open

Open, you absorb pressure and turn it into hurry. The rush to be finished is usually borrowed, and it does not stop when the task does.

Questions
What is the difference between defined and open?

A defined center is colored in and works the same way for your whole life. An open center is white and takes in that energy from the people and places around you. Defined is consistent, open is receptive.

Which center is most often open?

The Head. Across the charts we calculate it is open in about 74 percent of them, which is why so many people feel pressure to answer questions that were never theirs.

Are open centers a weakness?

No. Open centers are where you take in the world, and over time they become where you understand other people best. The difficulty is only in mistaking what you absorb for who you are.

How many centers should be defined?

There is no should. Reflectors have none defined, and most charts have between three and six. More defined means more that is consistently yours; more open means more that you take in.

Can a center change from open to defined?

Not in your own chart, which is fixed at birth. But another person, or a transit, can temporarily complete a channel and define a center for as long as that connection lasts, which is why you feel different around certain people.
