Two charts side by side, and the weather between them

Two signs

Zodiac compatibility

Choose two signs and see where they rest easily beside each other, and where the weather turns interesting. You get a score and a short reading, free and with no account needed. Sun signs are where it begins; a comparison of two full charts says far more.

Under the tool, all 78 pairings of the 12 signs have pages of their own, from Aries with Aries to Pisces with Pisces. A pairing page tells you what draws the two together, what flows between them, where they rub, how they love and what each has to give, with the element, modality and ruling planet of both signs set beside the text.

The score follows the tradition: it weighs the aspect between the two signs on the zodiac wheel first, then their modality, then their ruling planets, and the tool, the app and the pairing pages all give the same number. Signs of one element meet most easily, square signs push each other, and opposite signs each hold what the other has to learn. Every pairing was written by hand in English from that tradition and read again by a second reader.

Questions people ask

Which star signs are most compatible?

Signs of the same element meet most easily: Aries, Leo and Sagittarius in fire; Taurus, Virgo and Capricorn in earth; Gemini, Libra and Aquarius in air; Cancer, Scorpio and Pisces in water. These trines score highest here, and the sextiles come close behind: fire with air, or earth with water, two signs apart.

Which star signs are least compatible?

The most friction comes in squares, signs three apart that share a modality and pull different ways, such as Taurus and Leo or Scorpio and Aquarius, and in quincunxes, five signs apart, such as Leo and Capricorn. The lowest scores go to these pairs, and each of their pages says plainly what the friction asks of both.

Are two people of the same sign compatible?

Yes. Two of the same sign share an element, a modality and a ruling planet, so they recognise each other at once and rarely need to explain themselves. Their friction comes from the same place: two Aries, for instance, are two leaders on one road.

Do opposite signs attract?

Yes. Opposite signs such as Aries and Libra or Taurus and Scorpio share a modality and stand in elements that feed each other, so the pull between them is strong and each holds what the other has to learn.

How is the compatibility score calculated?

The score weighs three things in turn: the aspect between the two signs first, then their modality, then their traditional rulers. The same score appears in the tool, on the pairing pages and in the app.

Can incompatible star signs make it work?

Yes. A square or a quincunx brings more friction, and its pairing page names what that friction asks of each. A comparison of the two full birth charts also reads the Moon, Venus and the rising sign, and there a couple often finds the ease its Sun signs lack.
