What's the "right" house system for me to use?

This week, one of you asked a great question in the community forum:
Should I use Whole Sign or Placidus for my birth chart?
Here's how I replied đ:
(Pro astrologers & advanced astrology students - please chime in on the community thread! I'd love to know how you're thinking about this.)
Ahh, the age-old question: which astrology house system should I use?
As someone whose chart placements are almost 100% different between Whole Sign & Placidus, this is something Iâve personally explored in depth :) In fact, I started my astrology journey with Placidus, and ultimately moved over to Whole Sign because as I evolved, it became the system that felt truer to me.
This could be a whole class - but Iâll give you a quick technical overview of each system below, as well as my perspective on picking âthe right oneâ.
Hereâs the deal:
Whole Sign is the âOGâ house system, from a Western astrology perspective.
This is what the ancient Greeks used.
Itâs simple (which is why itâs great for beginners), and I (personally) find it to be more archetypal simply because in Whole Sign, every house (i.e. life area) is the same size and contains ONE zodiac sign. That sign has a planetary ruler (and, according to the Greeks, rulers are the visible planets only - not outer ones like Uranus, Neptune or Pluto).
It also uses certain timing techniques - like profections - that just donât âworkâ with other house systems.
Placidus is a more âmodernâ house system.
It was popularized in the 1600âs by a monk named Placidus de Titi.
It uses whatâs called a âtime-basedâ system that basically gives each house a different size (and thus importance). Houses can be really big - in which they can contain 2 (or more) signs - or really small (in which case you could end up with 3+ houses that all contain the same zodiac sign!).
Some people find Placidus to be more personal & nuanced because charts look more different with this system. But, itâs also not very useful for extreme North / South latitudes (because you could end up with your chart being entirely 6th/12th house, for example, containing 6 different zodiac signs).
There are other house systems too, like Porphyry, or Vedic. All have a different flavor, and some (like Vedic) even have a totally different approach to astrology.
SoâŚwith all of these house systemsâŚhow do we choose?
I wish there was an easy answer. But most astrologers agree...thereâs no one ârightâ house system.
- There are medical astrologers who start with Placidus first, then reference Whole Sign (in the same reading!).
- Then there are Hellenistic astrologers who use Whole Sign exclusively.
- Or evolutionary astrologers who prefer Placidus because itâs better at showing the soulâs journey & evolution through a particular area of life (e.g you can start with the cusp sign, evolve through & activate the interception, and culminate with a partially contained sign).
Hereâs my personal perspective:
Start with one, explore them all.
I believe astrology is useful mostly because it tells us a story about who we are. That story evolves over our life, as the result of our experiences and our choices.
And sometimes, we get âstuckâ in ruts around our stories - either due to our life experience (e.g. trauma can do that), or due to over-focusing on a particular societal narrative, or âwhat my chart saysâ.
-
If the story frees you? And evolves you? Thatâs good.
-
If it helps you make sense of your current life experience? And co-create with it more effectively? Thatâs also good.
-
If the story starts to feel contracting, or like youâve outgrown it, or like it doesnât quite landâŚmaybe itâs time to explore a new house system.
-
Or, if youâre ready for an up level, and you want to simply see more possibilities for what you (and your life) might be likeâŚit can be GREAT to explore another house system!
Sometimes, what we see in our charts wonât quite land.
That could be because youâre not fully embodying it yet. Or, it could simply be that another âsystem of selfâ might resonate more. Both are ok.
To me, astrology is an invitation to explore.
Who you are. What youâre here for. What you want to DO in this life. And how youâre going to take action to do it.
So which house system should you use?
Iâd say go with the one that feels true for you right now.
And if you come to a place where you want something fresh - like a new perspective - explore another house system.
Thereâs no rush. People spend lifetimes studying this stuff (not to mention figuring out who they are).
Sorry the answer isnât more simple :) Itâs like when you ask a question and someone says âit dependsâ. Gah. But in this case, it truly does (it depends on you).
