Within Western Astrology there are several house systems used by astrologers. Personally I use the equal house system, my teacher uses it, the Faculty of Astrology uses it. But most of all it resonates with me. I will explain you a little bit more about the equal house, whole sign and placidus house systems.
Equal House System this is my preferred system
What it is:
- The Ascendant always marks the start of the 1st house
- Then, each house is exactly 30° after that, regardless of sign boundaries
- So if your Ascendant is at 20° Virgo, your 2nd house starts at 20° Libra, and so on
Where it comes from:
- It’s an ancient system, used in Hellenistic astrology alongside Whole Sign
- Was revived in medieval and Renaissance astrology
- Still popular in psychological, esoteric, and Vedic approaches today
Why it makes sense:
- It keeps the Ascendant personal, anchoring it to your true rising degree
- It acknowledges that your identity (1st house) is not the whole zodiac sign, but a unique slice of it
- You still get to experience multiple signs within one house (like Pisces–Aries in 7th), which can feel more true in real life
For me this fits my experience. I can feel the mix of signs in a house, while not oversimplifying personality or relationships. I also like that it’s not too abstract or rule-heavy.
Whole Sign Houses: currently trendy, especially in traditional astrology
What it is:
- The sign of your Ascendant becomes the whole 1st house, no matter the degree
- So if your Ascendant is 20° Virgo, the entire sign of Virgo is the 1st house, Libra the 2nd, and so on
Where it comes from:
- This is the oldest house system, used in Hellenistic astrology (~2nd century BCE)
- Was forgotten in the West for a long time, but revived in the 1990s–2000s by traditional astrologers
Why some people like it:
- It simplifies charts, making prediction (e.g. annual profections, transits) more direct
- Clear boundaries: one sign per house
- Easier to use for timing techniques like Zodiacal Releasing, Solar Returns, etc.
Critiques (from my POV):
- It feels too black-and-white, suddenly your entire 7th house is just Pisces, not Pisces and Aries
- Ascendant degree is lost as the anchor which to me feels less personal
- Can make people obsess about literal 3D questions (“will I have 7 kids?”), because it emphasizes traditional meanings like marriage, children, death, etc.
It feels too general or flattened. I would say the experience of life is more nuanced.
Placidus: the most commonly used modern system
What it is:
- A time-based system that divides houses by how long it takes signs to rise over the horizon
- House cusps are irregular (not 30° each), and in far northern/southern latitudes, houses can get distorted
Where it comes from:
- Developed in the 17th century by Placidus de Titis (Italian monk and mathematician)
- Became the default in modern Western astrology, especially psychological astrology
Why some people like it:
- Brings nuance to internal dynamics and timing
- Feels more psychological, suited to therapy and introspective work
- The Midheaven (MC) is used as the actual 10th house cusp (vs Whole Sign / equal where MC can fall in a different house)
Critiques (from my POV):
- Can get mathematically messy, especially in high latitudes (e.g. Scandinavia, Alaska)
- Some houses get huge and others get tiny which can be hard to interpret
- Feels too abstract or confusing if you want to feel the real energy of signs flowing
For me it is a little too much. I like clarity, symbolism that works viscerally, and a system that aligns with lived reality.
Why Equal house system makes intuitive sense for me:
- I experience life as flowing, not stuck in one sign per house
- I feel the energy of sign transitions in each area (e.g., relationships that move from Pisces to Aries – dreamy to assertive)
- I want a house system that is logical but intuitive, symbolic but grounded
- I honor the Ascendant as the truest beginning of your life story, not just “a sign”
