Zodiac Compatibility Chart: Which Signs Are Compatible? A Guide to All 12 Signs

"Which signs are compatible?" is one of the most common questions in astrology. The short answer: where two signs sit on the zodiac wheel gives a clue about how energy will flow between them. Signs of the same element understand each other easily, opposite signs attract each other, and signs in a square experience friction but can help each other grow. In this article we share the compatibility chart for all 12 signs and explain what it does and does not tell you.

An important note: we are talking about Sun signs here. For real relationship compatibility, the Moon, Venus, Mars and the rising sign matter at least as much as the Sun. So use the chart as a starting point, not as a final verdict.

How Is Zodiac Compatibility Worked Out?

Zodiac compatibility is based on the angle between two signs. The zodiac is a 360-degree circle and each sign covers 30 degrees. The distance between two signs corresponds to the traditional aspects of astrology:

• Same element (trine, 120°): the relationship between fire, earth, air or water signs among themselves. Considered the smoothest and easiest compatibility; both sides speak a similar language.
• Complementary element (sextile, 60°): fire with air, earth with water. A supportive, stimulating and lively match.
• Opposite sign (opposition, 180°): the sign directly across the zodiac. It brings strong attraction and a sense of completion, but balance takes effort.
• Square (90°): signs of the same modality (cardinal, fixed or mutable) but different elements. They create friction and tension; handled well, this becomes a driving force that helps the relationship grow.

By element, the signs group like this: the fire signs are Aries, Leo and Sagittarius; the earth signs are Taurus, Virgo and Capricorn; the air signs are Gemini, Libra and Aquarius; the water signs are Cancer, Scorpio and Pisces.

Compatibility Chart for All 12 Signs

Pairings that look "incompatible" in the chart can still work. The tension between square signs gives both sides room to learn from each other, while the ease between same-element signs can sometimes turn into monotony. No sign pairing on its own means "it will never work."

Love Compatibility by Element

Fire signs (Aries, Leo, Sagittarius) love excitement, adventure and frankness. They tune into each other's energy easily, and the ideas of air signs fan their fire even more. With water signs they gain emotional depth, but need to watch their speed and reactivity.

Earth signs (Taurus, Virgo, Capricorn) look for trust, stability and concrete steps. They understand each other's rhythm easily, and their relationships with water signs gain emotional warmth. With fire signs they learn to be spontaneous; with air signs, to think flexibly.

Air signs (Gemini, Libra, Aquarius) want communication, exchange of ideas and freedom. They can talk with each other for hours, and the enthusiasm of fire signs gets them moving. With earth signs they learn to make their ideas concrete.

Water signs (Cancer, Scorpio, Pisces) connect through emotional depth, loyalty and intuition. They understand each other without words, and earth signs give them safe ground. With air signs they learn to put their feelings into words.

The Sun Sign Is Not Enough: A Real Compatibility Chart

Sun sign compatibility shows the general tone between two people's core characters. But other placements shape the day-to-day texture of a relationship:

• Moon sign: emotional needs and the sense of safety. When two people's Moons are compatible, it is easier to comfort each other.
• Venus sign: how you love and what attracts you. See our Venus sign article for details.
• Mars sign: passion, desire and how you handle conflict. Our Mars sign article covers this.
• 7th house: the area of partnerships and marriage in the chart; read it with our 7th house guide.

Comparing two birth charts planet by planet is called synastry, and it is usually what people mean by a compatibility chart. We explain how it works step by step in our synastry guide. The method that builds a single relationship chart from the midpoints of two charts is called the composite chart. For broader relationship dynamics, also see the astrological dynamics behind love compatibility.

In the Spatyom app, when you add a friend, your compatibility is calculated from both people's own birth charts. Your birth details are not shown to your friend; only the compatibility result is shared.

Frequently Asked Questions

Which signs are the most compatible?

Traditionally, signs of the same element find the easiest compatibility: Aries, Leo and Sagittarius in fire; Taurus, Virgo and Capricorn in earth; Gemini, Libra and Aquarius in air; Cancer, Scorpio and Pisces in water. Fire with air and earth with water are also considered mutually supportive pairs.

Are opposite signs compatible?

Opposite signs (Aries-Libra, Taurus-Scorpio, Gemini-Sagittarius, Cancer-Capricorn, Leo-Aquarius, Virgo-Pisces) feel a strong attraction because each sees in the other what it lacks. These relationships can be fulfilling, but they require both sides to be willing to compromise.

How do you make a compatibility chart?

You need each person's date, time and place of birth. Two birth charts are drawn from this information and the aspects between the planets are compared. This method is called synastry.

If our Sun signs are incompatible, will the relationship fail?

No. Sun sign compatibility is only one layer of a relationship. Compatibility between the Moon, Venus, Mars and rising signs can build a strong bond even when the Sun signs are square. Astrology shows tendencies; what really shapes a relationship is the effort and communication of both people.
