Pairing tool
Zodiac Compatibility Calculator
Choose two tropical sun signs. The guide returns a short verdict, a few sentences on chemistry and friction, and a climate label you can check against a published rule. It does not invent a percentage from a gut feeling, and it does not use a birth hour.
Or jump into a pairing
Compare two sun signs
The result uses sun signs only. It is not a natal chart, not synastry by birth time, and not a promise that two people will last. Swap the two names and the climate stays the same: the guide treats the pairing as shared weather.
This is entertainment. It is not counseling, not a medical reading, and not a guaranteed forecast. If a paragraph makes cruelty sound like a sign, close the page and deal with the behavior.
How the climate is named
Each sign has an element (fire, earth, air, water) and a modality (cardinal, fixed, mutable). Same or complementary elements — fire with air, earth with water — score 3. Fire with earth or air with water scores 2. Fire with water or earth with air scores 1. Different paces, or two mutable signs, score 2 for modality. Two cardinal signs or two fixed signs score 1. Those two numbers are added. Five is an easy climate, four is steady, three is mixed, two is high-friction.
| Ingredient | 3 or 2 | 1 |
|---|---|---|
| Element | Same, or fire–air, or earth–water (3). Fire–earth or air–water (2). | Fire–water or earth–air |
| Modality | Different paces, or two mutable signs (2) | Two cardinal or two fixed |
Zodiac compatibility chart
Many results pages print a zodiac compatibility chart: twelve signs across and twelve down, each cell a score or a heart. This guide does not invent those 144 numbers. The table above is the whole chart we use — two ingredients, four climate names — applied to any pair you choose. If you want a grid of percentages, you will not find one here. If you want a label you can check against a published rule, run two suns.
The paragraph is not one template with the names swapped. Element pairs, modality pairs, and each sign’s habit in love are combined. A few well-known pairs, including several Capricorn pairings, get an extra note. Swapping the two signs does not change the result.
