Cancer in love: Cancer loves deeply and builds a sense of home with their partner. They're devoted and affectionate, needing emotional security and reassurance — and they remember both kindnesses and slights.
Water signs read love as felt safety, which the other water signs and the earth signs provide, and the detached air signs often do not. As a cardinal sign it starts things, so the friction usually comes with the other cardinal signs, which all want to be the one deciding.
The tradition usually names Scorpio (4th), Pisces (3rd), Taurus (1st), Virgo (2nd) as Cancer's classic matches and Aries (12th), Libra (9th) as the difficult ones. On our scale, which scores element, modality and opposition rather than reputation, the two mostly agree, which is what you would expect when the tradition and the arithmetic are both reading the same elements.
Best match on our scale is Taurus at 92/100; the pairing that asks the most of both people is Aries at 41/100. A low score is a translation problem, not a verdict: plenty of the hardest pairings on this list are also the ones people describe as the most alive.
Cancer with every sign, best to worst
How to read these scores
Element, modality and opposition, weighed the way the elements and modalities page explains. What a Sun-sign score cannot see is a birth chart, so treat it as the opening read and run the synastry calculator with both charts for the real thing.
Cancer's element-mates are Scorpio and Pisces, and their hubs are the natural next read. The whole grid is on the zodiac compatibility page.
