How the comparison is built
Classical astrology judges two signs by their structure. Elements (fire, earth, air, water) describe temperament; modalities (cardinal, fixed, mutable) describe how each sign acts; the angle between the signs — 0°, 30°, 60°, 90°, 120°, 150° or 180° — is read like an aspect between planets; polarity groups signs into active and receptive; and each sign’s ruling planet adds a motive of its own. The tool shows all five for every one of the 78 possible pairs.
Why there is no love percentage
A single score hides the reasoning, and astrologers themselves read squares and oppositions as growth and attraction, not as failure. Instead you get a transparent count of how many factors flow easily and a short explanation of each one, so you can see where a pair is naturally in tune and where it needs adjusting.
Sun signs are only the start
Compatibility based on Sun signs is the simplest layer. Astrologers also compare Moon, Venus and Mars signs and the rising sign, which need a birth time. Relationships, of course, depend on the people involved; the readings here follow tradition and are meant for entertainment and self-reflection.
Frequently asked questions
Which zodiac signs are most compatible?
Traditionally, signs of the same element (trines, such as Aries and Leo) and signs of complementary elements (sextiles and oppositions, such as Aries and Gemini or Aries and Libra) are considered the easiest combinations.
Are squares and oppositions bad matches?
Not in astrology. A square brings friction that astrologers read as motivation, and an opposition brings strong attraction between two sides of the same theme. Both simply need more conscious adjustment.
What if I don’t know my partner’s sign?
Enter their birth date instead; the tool calculates the sign from the Sun’s real position. If they were born on the day the Sun changed signs, it tells you to check with a birth time.
Does the order of the signs matter?
No. Aries and Leo give the same result as Leo and Aries, which is why there are 78 unique pairs, including twelve same-sign pairs.
