Compatibility Chart for Zodiac Signs

Zodiac compatibility charts profess to help daters find ideal mates based on how well the personalities of people with the different signs align. The ability of these charts to deliver, of course, depends on two conditions being met: that zodiac signs can predict personalities and that we can predict what personality types are most ideally suited to each other.

Compatibility

Unfortunately, the reliability of these zodiac charts is suspect, to say the least. None of the claims of zodiac compatibility charts is supported by research evidence. Instead, the reality is a little less dreamy and a lot more realistic.

"Compatibility" in the sense of certain personality types being naturally better together is a fallacy. What's more, while zodiac signs may be a fun topic to discuss with friends, evidence to support their usefulness in predicting personality or the future is lacking. However, if you are looking to these charts merely for some inspiration and fun, rather than 100% accuracy, then, by all means, enjoy.

History of Astrology

Let's first understand where the zodiac system originates. Astrology was first used by the Babylonians to predict seasons and celestial events. In this way, for 2000 years, astrology and astronomy were viewed as the same form of science.

Astrology was introduced to the Greeks in the early 4th century B.C., and Plato, Aristotle, and other philosophers highly regarded it. As it was embraced by the Romans and spread to the world as a way to predict weather and other phenomena, so, too, was the concept of the zodiac—which first originated in Egypt.

The zodiac system was based on the 12 lunar cycles required for the sun to return to its original position and 12 constellations linked to the seasons. Indeed, each Zodiac sign is linked to either fire (Aries, Sagittarius, Leo), water (Cancer, Scorpio, Pisces), air (Libra, Aquarius, Gemini), or earth (Capricorn, Taurus, Virgo).

How Charts Are Made

Zodiac charts are based on several "readings" from a person's astrological makeup. One of the most important and well-known factors is a person's sun sign, which is what we often see referred to in popular horoscope columns. Also called the 12 signs of the zodiac, sun signs are based on the Earth's yearlong rotation around the sun and are said to convey character traits.

There are also 12 houses, which are based on the Earth's daily rotation and are intended to relate to relationships, finance, travel, and more. Each person is also assigned a moon sign that is supposed to inform their emotional portrait, and a rising sign that reflects a person's public persona.

An astrologer creates a person's individual chart and/or compatibility chart based on the relative positions of the planets, sun, and moon at the time of birth, using this alignment data to infer personality traits. Exactly how this alignment information is translated into real-world profiles and characteristics of individual people or couples is quite subjective and varies significantly from astrologer to astrologer.

Chinese Zodiac

There is a parallel zodiac compatibility system in China that also goes back centuries. In the Chinese zodiac tradition, each person is assigned one of 12 zodiac animals based on the year they were born. The 12 zodiacal animal signs in the Chinese calendar are rat, ox, tiger, rabbit, dragon, snake, horse, sheep, monkey, rooster, dog, and pig. Like the zodiac methodology in the Western tradition, each animal (rather than each sign) has personality traits attributed to them, as well as a system in which compatibility is assessed.

In general, according to the Chinese zodiac system, mates with a 4-year age difference are most suited to each other, while those that are six zodiac animals apart tend to be least compatible. There is more cultural than scientific significance to this system as, like in the Western zodiac tradition, there is also no empirical research to back it up.

Zodiac Compatibility

In the Western astrological tradition, determining compatibility is called synastry, a newer concept that was developed in the 1970s. In synastry, astrologists use multiple methods for creating birth charts for each person as well as for comparing them to assess the likely success of the match.

One prominent approach is to focus on each person's rising or ascendant sign (the zodiac sign that was rising on the eastern horizon) at the moment they were born, as well as the relative positions of the sun, moon, and planets. To determine compatibility, the characteristics attributed to the rising sign, sun, moon, and planets thought to be most significant at the time of each person's birth are then compared with the findings on the other person.

Zodiac compatibility hangs on the premise that compatibility, in terms of zodiac signs (in essence, when a person was born) and how various personality traits interact (do opposites attract or do similarities create a bond?), can help determine which people will make a good match.

One way to think about this is to understand that the zodiac aims to describe personality characteristics simply based on the time of year a person is born. To see how "accurate" this system, the first step would be to look up your sign and decide how well the description matches you. Additionally, you can compare how well your friends and relatives' personalities align with their sign descriptions.

This is a bit of a gamble since there is no evidence to support that you will be who your sign describes you to be. However, many fans who follow the zodiac system (as well as many astrologers) say science isn't the point and that zodiac compatibility should be considered more of a guide rather than a hard and fast prescription. If the zodiac characteristics resonate for you, there is probably no harm in considering it—as long as you take the recommendations with a grain or two of salt.

If you've spent a lifetime not identifying with the description of your sign, it's probably best not to base any compatibility decision on what a zodiac compatibility chart might say. Note that just like "headache" or "fatigue" can be symptoms for many ailments, these personality descriptions are rather vague and tend to be able to fit with many different types of people.

Personality Profiles

Below is a list of some of the common descriptors for the various signs.

Aries (March 21–April 19) 

Aries is the first sign of the zodiac and is described as bold, self-centered, impulsive, and independent. Aries is expected to be aggressive in a relationship and faithful if happy.

Taurus (April 20–May 20)

Taurus is described as practical, dependable, persistent, loyal, and possessive. In a relationship, Taurus is expected to demonstrate affection physically and may become jealous.

Gemini (May 21–June 20)

Gemini is described as independent, creative, and supportive. Gemini can also be unpredictable and crave change. 

Cancer (June 21–July 22)

Cancer is described as cautious, secretive, sensitive, complex, moody, and needy. In a relationship, Cancer is expected to be nurturing and empathetic, with a desire to please their partner.

Leo (July 23–August 22)

Leo is described as a faithful partner who demands loyalty. Leos can be bossy, demanding, flamboyant, outgoing, loyal, and sincere.

Virgo (August 23–September 22)

Virgo is described as analytical, realistic, knowledgeable, predictable, detail-oriented, and modest. In a relationship, Virgo is expected to be detached and analytical and favor an equal partnership. They may be judgmental and not forgive easily.

Libra (September 23–October 22)

Libra is described as a good listener, loyal, and fair. Libra can also be resentful, spiteful, and overindulging. Libras are seen as creative, sociable, and balanced individuals.

Scorpio (October 23–November 21)

Scorpio is described as powerful, brooding, and magnetic. In a relationship, Scorpio is seen as adventurous and loyal. They may also be viewed as jealous and unreasonable.

Sagittarius (November 22–December 21)

Sagittarius is described as upbeat, loyal, open, honest, generous, and happy. In a relationship, Sagittarius may not forgive easily.

Capricorn (December 22–January 19)

Capricorn is described as organized, classy, serious, and pragmatic. In a relationship, Capricorn is loyal, hardworking, but aloof and practical.

Aquarius (January 20–February 18)

Aquarius is described as rebellious, independent, open-minded, and honest. In a relationship, Aquarius is viewed as friendly and loving. However, they can also be unfaithful and distant.

Pisces (February 19–March 20)

Pisces is the last sign of the Zodiac and is described as dreamy, romantic, compassionate, and sensitive. In a relationship, Pisces is expected to be strongly devoted and to put the needs of a partner ahead of their own. Pisces can also be too sensitive.

Personality Compatibility

Let's say that you do happen to think that the description of your sign matches you well. What's next? Most would suggest you check what other signs are your "best matches" and leave it at that. Again, this presupposes that these characteristics can be attributed to everyone born under a certain sign and that we can predict which personalities will mesh well together. Unfortunately, there is no scientific evidence to back these assumptions up.

What does research tell us about this issue? Instead of personality match-ups, what is most important is how well a potential partner's personality matches what you perceive to be the personality of your ideal mate.

Research suggests that it's worthwhile to consider what the personality of your ideal partner would look like. Would you be looking for someone who is open, honest, caring, dependable, exciting, funny, smart, or something else?

If you're not sure what you're looking for, have a second look at the list of descriptions above and figure out which one best describes the personality of your ideal mate. Then, when you meet a potential dating partner, consider how much they fit this profile.

Keep in mind, however, that the zodiac personality descriptions are quite general and by no means exhaustive. In other words, real people are likely to have a mix and match of the various traits across several signs—as well as to have key characteristics that aren't on the list at all.

Traits That Matter

Beyond considering what you are looking for in a partner, science tells us that compatibility does not hinge on specific personality traits. If you feel a spark of something for someone, you will likely be willing to work hard to make things work. You'll also be more likely to see the other person in a positive light and show them respect.

Plus, sometimes what people think or assume they want or should want in a partner might be very different from what actually makes them happy. So, it's also important to have an open mind and not only focus on looking for a specific "type." Instead, the following are personality traits that matter most to compatibility, for both you and your partner:

  • An attitude of goodwill
  • A congenial temperament
  • Enthusiasm for your partner
  • Willingness to work through differences

Rather than hinging on how specific characteristics relate to each other, compatibility evolves out of a desire to create it.

Lasting Relationships

Experts tell us that other key ingredients to lasting relationships include having similar core values, particularly on important issues like money and children. These are deep, impactful fundamentals of life that you will need to have some agreement on in order to make things work.

In contrast, enjoying the same hobbies or activities is not as important in the bigger picture. Recreation choices evolve over time and don't always need to be done together. A relationship based on these shared interests alone may not survive.

Finally, a lasting relationship should be built upon a sense that you are creating something together and support each other's mission in life. This goes along with the personality traits of supporting each other and building each other up.

A Word From Verywell

In the end, compatibility is not so much about personality, but about the unique draw between you as well as your relationship skills and those of your partner. These skills reflect your willingness to work on being a better person for your partner, which is related to how much you hold them in high esteem (and vice versa), rather than simply what your zodiac charts say. Are you always looking for the best in your partner? If so, whether they are a Pisces or Capricorn isn't likely to matter so much.
