Capricorn and Aquarius: a semi-sextile
Capricorn and Aquarius are a cardinal earth sign and a fixed air sign. Neighbouring signs form a semi-sextile, an angle traditionally seen as mildly awkward. The two differ in element and modality, so they approach life in quite different ways, yet each is said to have what the other is still learning. That can feel unfamiliar at first. With curiosity on both sides, the relationship becomes a steady exchange in which each rounds out the other.
Capricorn and Aquarius in love
Capricorn brings stability and commitment: plans are made, promises are kept and the future feels secure. Aquarius brings originality and friendship: new perspectives, interesting people and plenty of freedom. Earth and air are traditionally considered an unusual pairing in love. Earth thinks in practical terms and wants stability, air thinks in ideas and wants variety. Earth may find air unreliable or scattered, and air may find earth heavy or predictable. When it works, air brings fresh perspectives and earth turns ideas into reality. Respecting each other’s way of thinking is essential. In our model, love scores 44%.
Capricorn and Aquarius as friends and colleagues
A cardinal and a fixed sign are said to combine well in practical matters: the cardinal sign starts things and the fixed sign carries them through, a division that can work very well at work. Friction comes when the cardinal side wants to change direction and the fixed side wants to stick to the plan, so it helps to agree early on when a change of course makes sense. Friendship scores 50% and work 58% in our rule-based model. Work is the strongest of the three areas for this pair.
Where it can rub, and what helps
Capricorn can seem cool or too focused on work, and may put duty before feelings. Aquarius can seem distant or stubborn and may retreat into ideas when feelings run high. Capricorn needs respect, reliability and a partner who takes its goals seriously. Aquarius needs space, honesty and a partner who is also a real friend.

How the score is calculated
The score is rule-based and fully transparent. It starts from the angle between the two signs, using the traditional aspects of astrology: a trine (four signs apart, same element) scores 90, a sextile (two apart) 80, the same sign (conjunction) 68, an opposition 62, a semi-sextile (neighbouring signs) 52, a square (three apart) 45 and a quincunx (five apart) 42. Small adjustments are then made for the element pair and the modality pair, separately for love, friendship and work. The overall score is the average of the three.
Elements and modalities
Traditionally, fire and air are said to feed each other, as are earth and water, while fire with water or earth with air is considered harder going. Two fire signs get a bonus for passion and friendship, two earth signs for work. The modality adjustment looks at how two signs handle action: two cardinal signs may compete for the lead, while a cardinal and a fixed sign tend to divide work well, as one starts and the other finishes. The tool lists every adjustment, so you can see where each point comes from.
What the score can and cannot tell you
The calculator compares Sun signs only. It does not use birth charts, so it says nothing about the Moon, Venus, the rising sign or anything else astrologers would look at for a full synastry. More importantly, astrology has no scientific basis: no study has shown that zodiac signs predict whether two people get along. Treat the score as entertainment and a fun way to talk about relationships. Real compatibility depends on communication, shared values and effort, not on birth dates.
Frequently asked questions
Which zodiac signs are most compatible?
By the traditional rules used here, signs of the same element (a trine), such as Aries and Leo or Taurus and Virgo, score highest, followed by sextiles such as Aries and Gemini.
Are Aries and Leo compatible?
Yes, by traditional rules they are one of the best matches: two fire signs four apart, forming a trine. Open the Aries and Leo page for the full breakdown.
Can two people with the same sign be compatible?
Yes. Same-sign pairs score in the middle range: they understand each other easily but also share the same weak spots.
Why is the score different on other websites?
There is no standard formula. This tool uses published, traditional rules and shows each step, so you can see exactly how the number is reached.
Does the calculator use my birth chart?
No. It only compares the two Sun signs. For your planetary positions, use the birth chart calculator.
