What zodiac signs should not be together?
None, on the evidence. The lowest-scoring pairings are squares and quincunxes, signs 90 or 150 degrees apart that share neither element nor mode, led by Aries with Virgo at 76.0. But the gap between the best and worst pairing is only 11.5 points, while couples inside a single pairing typically spread across 24.1 points. A particular Aries and Virgo couple can outscore a particular Libra and Libra couple, and in our sample it often did.

Compatibility by date of birth
Sun signs only use the birth date. A full compatibility reading uses each person's date, time and place of birth to cast two complete charts, then compares the Moon, Venus, Mars and every angle between the two charts. That is where the other 75.7% of the score lives. The free compatibility test at the top of this page does exactly that and scores the pair out of 100. To learn to read the comparison yourself, start with how to read a synastry chart.
How zodiac compatibility works
Compatibility in astrology starts with the elements. Fire signs are bold and warm, earth signs are steady and grounded, air signs are bright and social and water signs are deep and feeling. Signs of the same element share a language, which is why they sit highest on the chart.
The angle between two signs adds the next layer. A trine of the same element flows with ease. A sextile between complementary elements sparks friendly chemistry. A square brings heat and friction, while an opposition creates the magnetic pull of opposites. None of it is destiny: a challenging match with effort can outlast an easy one left untended.
Compatibility questions
What is a zodiac compatibility chart?
A zodiac compatibility chart rates how well each pair of Sun signs matches. Ours scores all 78 pairings out of 100, using the average full birth chart synastry score from a study of 60,000 chart pairs. Libra with Libra ranks highest at 87.5 and Aries with Virgo lowest at 76.0.
How is zodiac compatibility calculated?
Sun-sign compatibility looks at the angle between two signs and their elements. Signs of the same element form a trine and flow easily. Fire pairs with air and earth pairs with water. Squares and oppositions bring friction or magnetism. A full birth chart adds far more detail.
Which zodiac signs are most compatible?
In our study of 60,000 chart pairs every one of the ten highest-scoring pairings was a same-sign match, led by Libra with Libra (87.5), Taurus with Taurus (87.0) and Scorpio with Scorpio (86.5). Signs of the same element come next, such as Taurus with Virgo and Libra with Aquarius.
What zodiac signs should not be together?
No pairing is ruled out. The lowest average scores in our study were Aries with Virgo (76.0), Cancer with Aquarius (76.4) and Libra with Pisces (76.9), signs that sit 90 or 150 degrees apart. Yet scores inside a single pairing spread by about 24.1 points, so a given couple from a low pairing often outscores one from a high pairing.
Can I check compatibility by date of birth?
Yes. The free tool on this page casts both full birth charts from each person's date of birth and birthplace, plus the birth time if you know it, then scores the pair out of 100 across heart, spark, mind and rhythm. Without a birth time it skips the rising sign and houses but still compares the Sun, Moon, Venus and Mars.
How accurate is Sun sign compatibility?
It is a real but weak signal. Across 60,000 full-chart comparisons the two Sun signs explained 24.3% of the score. The rest came from the Moon, Venus, Mars and the aspects between the two charts, which need a full birth date, time and place.
Do incompatible signs ever work?
Yes. A square or opposition shows tension, not doom. Many lasting couples have challenging Sun-sign aspects but supportive Moon, Venus and Mars connections. Compatibility is about the whole chart and real effort, never the Sun signs alone.
Should I check Sun signs or whole charts?
Sun signs give a quick, useful snapshot. For real depth, compare whole charts, especially the Moon for emotional needs, Venus for love style and Mars for desire. Run a free birth chart reading to go beyond the Sun sign.
