Zodiac Compatibility Calculator
Two signs
Just for fun — this is entertainment, not real relationship advice. A score compares two sun signs only; how two people actually treat each other matters far more.
Aries and Leo are both Fire signs in a trine, the easiest angle on the zodiac wheel — bold, warm and quick to cheer each other on. Enjoy it, and remember it is still just for fun.
Example: Aries and Leo — both Fire signs in a trine — score 95%.
Behind the numbers
How the score is worked out
Two things decide the score: the elements of the two signs, and the aspect — the angle between them on the zodiac wheel. Add the two scores together for a result out of 95, shown as a percentage.
Aries + Leo: 45 (Fire + Fire) + 50 (trine) = 95%.
Element scores (out of 45)
| Element pair | Score |
|---|---|
| Same element (Fire + Fire, Earth + Earth…) | 45 |
| Fire + Air, or Earth + Water | 45 |
| Air + Water, Earth + Fire, or Air + Earth | 30 |
| Fire + Water | 20 |
Aspect scores (out of 50)
| Aspect | Signs apart | Score |
|---|---|---|
| Trine | 4 | 50 |
| Sextile | 2 | 45 |
| Same sign | 0 | 40 |
| Opposite | 6 | 40 |
| Square | 3 | 25 |
| Quincunx | 5 | 20 |
| Next-door signs | 1 | 15 |
A few comparisons
Example sign pairs
| Pair | Elements | Aspect | Score | Verdict |
|---|---|---|---|---|
| Aries + Leo | Fire + Fire | Trine | 95% | An outstanding match |
| Taurus + Virgo | Earth + Earth | Trine | 95% | An outstanding match |
| Gemini + Sagittarius | Air + Fire | Opposite | 85% | Excellent match |
| Pisces + Gemini | Water + Air | Square | 55% | A fair match |
| Aries + Cancer | Fire + Water | Square | 45% | A fair match |
Reading your result.
Same-element pairs usually click fast because they want the same things — two Fire signs push each other on, two Earth signs build steadily together.
A trine is the smoothest aspect and a square the tensest, but a square is not a bad sign on its own: it often means the two of you challenge each other to grow.
Opposite signs score well here because opposites attract — and because each one has what the other is missing. The friction usually shows up in small daily habits, not big values.
Do not take a low score to heart: this only compares sun signs. Moon signs, rising signs and — most of all — how you treat each other count for far more than any number on this page.
Good to know
Your zodiac questions, answered.
How is the compatibility score calculated?
The score is the sum of two parts: an element score out of 45 and an aspect score out of 50. Same-element and friendly-element pairs score 45, neutral pairs score 30 and Fire with Water scores 20. The aspect — the angle between the two signs on the zodiac wheel — adds 50 for a trine, 45 for a sextile, 40 for the same sign or an opposite sign, 25 for a square, 20 for a quincunx and 15 for next-door signs.
What do the four elements mean?
Fire signs (Aries, Leo, Sagittarius) are bold and energetic, Earth signs (Taurus, Virgo, Capricorn) are steady and practical, Air signs (Gemini, Libra, Aquarius) are curious and social, and Water signs (Cancer, Scorpio, Pisces) are sensitive and intuitive. Same-element pairs usually understand each other quickly, while Fire and Air, and Earth and Water, tend to balance each other well.
What is a trine, a square or an opposite sign?
These are the angles between two signs on the zodiac wheel. Signs four places apart form a trine, the easiest angle; signs three places apart form a square, the tensest angle; and signs six places apart sit opposite each other, which brings both attraction and contrast.
Can a low score mean a relationship will not work?
No. This calculator only compares two sun signs, which is a tiny slice of astrology and none of real life. Plenty of happy couples have a low score here, and plenty of high-scoring pairs still argue about the dishes. Treat the result as entertainment, not relationship advice.
