Pisces Compatibility
All 12 matches ranked by a computed synastry score — not by tradition.
Astrology entertainment. Pisces is a mutable water sign ruled by Neptune, and it merges and absorbs. How the scores are computed.
All 12 Pisces matches, ranked
Every other compatibility site ranks Pisces's matches by tradition — same element good, opposite sign difficult. We rank them by running real birth charts through a synastry engine and averaging the result, so the order below is computed rather than inherited. The index is relative: 100 is the strongest of all 78 sign combinations.
| # | Match | Index | Harmonious | Challenging | Element |
|---|---|---|---|---|---|
| 1 | Pisces & Pisces | 86 | 15.5 | 6.2 | Water |
| 2 | Pisces & Capricorn | 76 | 15.6 | 6.5 | Earth |
| 3 | Pisces & Scorpio | 74 | 15.7 | 8.1 | Water |
| 4 | Pisces & Taurus | 69 | 16.4 | 7.9 | Earth |
| 5 | Pisces & Cancer | 61 | 15.2 | 9.0 | Water |
| 6 | Pisces & Aquarius | 46 | 14.1 | 5.9 | Air |
| 7 | Pisces & Aries | 44 | 15.4 | 6.9 | Fire |
| 8 | Pisces & Libra | 43 | 14.6 | 8.8 | Air |
| 9 | Pisces & Leo | 29 | 13.2 | 8.4 | Fire |
| 10 | Pisces & Gemini | 27 | 16.0 | 8.1 | Air |
| 11 | Pisces & Sagittarius | 27 | 14.9 | 7.8 | Fire |
| 12 | Pisces & Virgo | 15 | 14.3 | 8.6 | Earth |

Pisces's top three matches, explained
1. Pisces and Pisces — 86/100
Two water signs read each other without needing the words, which is the whole appeal and the whole hazard -- there is no natural circuit-breaker.
Across the sampled chart pairings this combination averages 15.5 harmonious and 6.2 challenging contacts, with friction carrying about 22% of the total contact weight. The contact that recurs most is Sun conjunct Sun, present in 100% of pairings — your sun is conjunct their sun — similar life energy and identity. The recurring friction is Moon square Moon at 20%.
2. Pisces and Capricorn — 76/100
Water brings feeling, earth brings form -- traditionally one of the more naturally supportive element mixes, and the data usually reflects it.
Across the sampled chart pairings this combination averages 15.6 harmonious and 6.5 challenging contacts, with friction carrying about 27% of the total contact weight. The contact that recurs most is Sun sextile Sun, present in 100% of pairings — your sun is sextile their sun — similar life energy and identity. The recurring friction is Sun opposite Moon at 17%.
3. Pisces and Scorpio — 74/100
Two water signs read each other without needing the words, which is the whole appeal and the whole hazard -- there is no natural circuit-breaker.
Across the sampled chart pairings this combination averages 15.7 harmonious and 8.1 challenging contacts, with friction carrying about 29% of the total contact weight. The contact that recurs most is Sun trine Sun, present in 100% of pairings — your sun is trine their sun — similar life energy and identity. The recurring friction is Moon square Moon at 25%.
Who is a Pisces's soulmate?
On the computed ranking above, Pisces scores highest with Pisces, Capricorn, Scorpio — and lowest with Virgo. But that ranking is an average over archetypes, and it is worth being blunt about what it can and cannot tell you: your Sun sign is one of roughly a dozen placements that matter in synastry, and it is the slowest-moving of them. Two Piscess born three weeks apart have different Moons, different Venus placements and different Rising signs, and those decide far more about who fits them than the Sun does.
Which is why the useful version of this question isn't "which sign is my soulmate" but "which birth dates fit my actual chart" — a question that needs your real birth details and a computation, not a table.
Frequently asked questions
Which sign is most compatible with Pisces?
On our computed index, Pisces — 86/100, #4 of all 78 sign combinations. The ranking comes from scoring real sampled birth charts, not from element tradition.
Which sign is least compatible with Pisces?
Virgo scores lowest at 15/100. That means the archetypes have the least natural support and the most friction — not that two real people with those Sun signs can't work.
Does Pisces compatibility depend on more than the Sun sign?
Overwhelmingly, yes. Pisces is a Sun sign, and the Sun is the slowest-moving placement in a chart. The Moon, Venus, Mars and Rising sign differ between two Piscess born weeks apart, and they carry most of the synastry weight.
Is this Pisces compatibility ranking computed or written by hand?
Computed. We generate real birth charts for each sign, score every combination with the same engine that runs the live calculator, and average the results. Nothing on this page is a hand-assigned percentage.
