Calculateur de Compatibilité Gratuit en Ligne
Découvrez la compatibilité astrologique entre deux signes du zodiaque.
Zodiac compatibility explores how two sun signs interact based on their elemental nature, modality, and angular relationship in the zodiac wheel. While the full picture includes Moon sign, Venus, and rising sign, sun sign compatibility offers a reliable starting point for understanding relationship dynamics.
The four elements and compatibility
| Element | Signs | Best with |
|---|---|---|
| 🔥 Fire | Aries, Leo, Sagittarius | Fire, Air |
| 🌱 Earth | Taurus, Virgo, Capricorn | Earth, Water |
| 💨 Air | Gemini, Libra, Aquarius | Air, Fire |
| 💧 Water | Cancer, Scorpio, Pisces | Water, Earth |
What compatibility scores mean
85–100% (Excellent): Signs of the same element or complementary elements — natural understanding, shared values, and high emotional resonance. 70–84% (Great): Strong connection with minor friction points that add depth rather than conflict. 55–69% (Good): Solid foundation with meaningful differences that require communication. 40–54% (Fair): Real challenges but also high growth potential if both are committed. Below 40% (Low): Requires significant effort and mutual respect — challenging but not impossible.
Beyond sun signs
Sun sign compatibility is a starting point, not a verdict. Moon sign (emotional nature), Venus sign (love style), and rising sign (outward personality) all shape relationship dynamics. Many couples with "incompatible" sun signs have strong Moon or Venus connections that sustain the relationship. Treat compatibility scores as a lens for self-awareness, not a prediction.
Frequently Asked Questions
Which zodiac signs are most compatible?
Traditional high-compatibility pairings by element: Fire signs (Aries, Leo, Sagittarius) with each other. Earth signs (Taurus, Virgo, Capricorn) with each other. Air signs (Gemini, Libra, Aquarius) with each other. Water signs (Cancer, Scorpio, Pisces) with each other. Trines (same element) and sextiles (compatible elements) show strong synergy.
Are Scorpio and Pisces compatible?
Scorpio and Pisces are considered highly compatible — both are water signs sharing emotional depth, intuition, and sensitivity. Scorpio provides intensity and direction; Pisces brings creativity and empathy. They typically score 85–95% compatibility in water sign pairings.
Can incompatible zodiac signs have successful relationships?
Yes. Sun sign compatibility is just one factor in astrology. Moon sign, Venus sign, Mars sign, and rising sign all play significant roles. Many real couples have "incompatible" sun signs but high compatibility in other chart placements.
What makes two signs incompatible?
Square aspects (signs 90° apart: Aries-Cancer, Leo-Scorpio) create tension and friction. Opposite signs (180° apart: Aries-Libra, Taurus-Scorpio) have high tension but also high attraction — they challenge each other to grow.
Is zodiac compatibility scientifically valid?
No scientific study has validated zodiac sign compatibility as a predictor of relationship success. Personality compatibility depends on communication, shared values, and emotional intelligence — not birth month. Treat compatibility scores as fun, not prescriptive.
