How a 4th house overlay feels
The fourth house is home, family and emotional roots, so overlays here are felt privately. The planet person tends to make the house person feel at home — or disturbs their sense of security. These overlays are common in long-term partnerships and families because they describe living together, family ties and the emotional foundation beneath the relationship. They are usually felt more strongly over time than at first meeting.

Planet by planet
Their planets in your 4th house
Their Moon in your 4th house
Their Moon is deeply at home with you. One of the strongest overlays for emotional security and domestic closeness.
Their Mercury in your 4th house
Their Mercury brings conversation and activity into your home. Talk about family, the past and practical domestic plans.
Their Venus in your 4th house
Their Venus makes your home feel beautiful and loving. A favorable overlay for living together.
Their Mars in your 4th house
Their Mars stirs up your home life — energy for renovating and building, or tension at home and with family.
Their Jupiter in your 4th house
Their Jupiter expands and protects your home. Moving to a bigger place or growing a family together is traditionally favored.
Their Saturn in your 4th house
Their Saturn brings responsibility at home. Stable and committed, but family duties or old wounds can weigh on the bond.
Their Uranus in your 4th house
Their Uranus unsettles your home life — frequent moves, unconventional living arrangements or sudden domestic changes.
Their Neptune in your 4th house
Their Neptune creates a dreamy, idealized home together, with a risk of unclear boundaries around family.
Their Pluto in your 4th house
Their Pluto transforms your family life and emotional foundations. Powerful, sometimes difficult, dynamics at home.
Overlays run both ways: check where your planets fall in their chart too. Houses show where the other person’s influence is felt; aspects between the charts show how well the two of you actually get along.
House person and planet person
Who feels a 4th house synastry overlay more?
The house person feels a 4th house overlay more privately: the planet person becomes part of their sense of home, family and safety, or unsettles it. The planet person often feels unusually at home with the house person, sometimes like family from the start, and may not see how deep into the other person's private life they have reached.
By rising sign
Whose Sun lands in your 4th house
With whole-sign houses your 4th house is the sign 3 steps on from your rising sign. A partner born while the Sun was in that sign has their Sun in your 4th house; their other planets need their own chart.
| Your rising sign | Your 4th house | Partner’s Sun there if born |
|---|---|---|
| Aries rising | Cancer | June 21 – July 22 |
| Taurus rising | Leo | July 23 – August 22 |
| Gemini rising | Virgo | August 23 – September 22 |
| Cancer rising | Libra | September 23 – October 22 |
| Leo rising | Scorpio | October 23 – November 21 |
| Virgo rising | Sagittarius | November 22 – December 21 |
| Libra rising | Capricorn | December 22 – January 19 |
| Scorpio rising | Aquarius | January 20 – February 18 |
| Sagittarius rising | Pisces | February 19 – March 20 |
| Capricorn rising | Aries | March 21 – April 19 |
| Aquarius rising | Taurus | April 20 – May 20 |
| Pisces rising | Gemini | May 21 – June 20 |
Sun-sign dates shift by a day in some years. Equal and Placidus houses can give a different answer near a cusp; the synastry calculator places every planet of both charts.

House type
angular
This house pairs with the 10th across the chart — public standing and direction of work — and the two work as one axis. A planet landing here looks straight across at that house, so the two readings belong together rather than separately.
It is an angular house, which sits on an axis of the chart, so it is the group most distorted by an inexact birth time. Its natural ruler is the Moon, so a partner's Moon arriving here doubles the theme rather than adding a new one.
Being angular, it shifts first when the birth time is off. How much →
The 4–10 axis
Home, family and the private self sits opposite public standing and direction of work. A planet in one faces the other across the chart, so an overlay here is always a statement about both — they end up inside the part of your life outsiders do not see; at the 10th-house end, the relationship becomes visible to others and affects how you are read.
