We Analyzed 32,736 Zodiac Compatibility Combinations — Here’s What the Data Shows
Published 2026-06-15 · 6 min read
Most compatibility articles recycle the same zodiac clichés. We did something different: we generated and scored 32,736 unique astrological compatibility combinations — every zodiac pairing, across both partners' genders and 30 relationship contexts — then analyzed the numbers. The average across 16,368 English pairings was 73.8, but the averages hide a far more interesting story.
Methodology: compatibility scores (1–100) for all 12×12 sign pairings × 4 gender combinations × 31 relationship contexts. Rankings aggregate those scores. The full dataset powers nostradamu.com/compatibility.
🏆 The 10 Most Compatible Zodiac Pairs
| 1 | Aries + Leo | 78.3 |
| 2 | Cancer + Scorpio | 77.3 |
| 3 | Pisces + Scorpio | 77.1 |
| 4 | Leo + Sagittarius | 77.0 |
| 5 | Aries + Sagittarius | 76.7 |
| 6 | Cancer + Pisces | 76.5 |
| 7 | Taurus + Virgo | 75.9 |
| 8 | Aquarius + Gemini | 75.6 |
| 9 | Gemini + Libra | 75.6 |
| 10 | Aquarius + Libra | 75.4 |
The top is dominated by same-element pairings — confirming the oldest rule in astrology with hard numbers.
💔 The 10 Least Compatible Pairs
| 1 | Capricorn + Gemini | 70.4 |
| 2 | Gemini + Scorpio | 71.6 |
| 3 | Aries + Capricorn | 71.9 |

| 7 | Gemini + Taurus | 72.2 |
| 8 | Leo + Virgo | 72.5 |
| 9 | Aries + Virgo | 72.5 |
| 10 | Aries + Pisces | 72.5 |
Capricorn + Gemini lands last — earth's caution meeting air's restlessness. Yet even the "worst" base pairing scores above 70: no pairing is doomed. The real damage shows up by context.
🔥 Element Compatibility, Ranked
| Fire + Fire | 77.3 |
| Water + Water | 77.0 |
| Air + Air | 75.5 |

| Air + Fire | 73.7 |
| Air + Earth | 73.1 |
| Air + Water | 73.0 |
| Fire + Water | 73.0 |
| Earth + Fire | 72.8 |
Like attracts like. Matching elements top every spot; the classic clashes — Earth + Fire and Fire + Water — sit at the bottom.
💬 Context Changes Everything
The same two signs can be soulmates or a disaster depending on the dynamic.
Healthiest
| Soulmates | 79.9 |
| Attraction | 79.7 |
| Long-term | 78.3 |
| Moving in together | 78.3 |
| Sexually | 78.2 |
Most Damaging
| Trust issues | 61.0 |
| Ghosting | 62.2 |
| Silent treatment | 68.4 |
| Fighting | 69.7 |
| Toxic | 47.3 |
The headline finding: a "toxic" dynamic drops compatibility by ~30 points versus a soulmate framing of the exact same signs. Astrology doesn't decide your fate — the pattern you fall into does.
🎯 The Extremes
- Highest score (92): Cancer woman + Scorpio woman, as soulmates. Two deeply intuitive water signs.
- Lowest score (25): Aries woman + Cancer man, in a toxic dynamic. Fire impatience meets water sensitivity at its worst.
Across 16,368 pairings, gender combination barely moved the needle (74.7 to 73.0). Compatibility is driven by signs and context, not gender.
