Romantic compatibility stems from a variety of factors—your way of life, your principles, your goals. And while you usually determine how compatible you are with someone by getting to know them, you can also glean a lot just from knowing the person’s zodiac sign. So if you are wondering if you and your significant other are written in the stars, then keep reading for more cosmic insight into your partnership.

Why Your Sun Sign is So Important

Your sun sign contains a lot of eye-opening information about your core personality and certain zodiac signs are better suited for each other than others. For instance, a Leo sign pairs best with other fire signs and air signs like Gemini and Libra. The Leo personality can come across as confident, charismatic, and desperate for the limelight. Leos love being the center of attention and air signs are great at providing adoration and affection for their partners. And fellow fire signs can spark inspiration and spontaneity in a Leo woman or man.

How the Elements Affect Compatibility

In astrology, how compatible you are is often based on the specific element associated with your sun sign. Libra, Gemini, and Aquarius are air signs. Leo, Sagittarius, and Aries are fire signs. Taurus, Virgo, and Capricorn are earth signs. And Scorpio, Cancer, and Pisces are water signs. Air and fire signs usually go well together while earth and water signs make for a solid partnership—the same as it would work in nature. A passionate fire sign like Leo might clash with a practical and patient earth sign like Virgo or Capricorn.

In astrology, opposites on the zodiac wheel often attract—like Capricorn and Cancer—and actually may lead to a good romantic match. The rather different personality traits of the polar signs may enhance (rather than hinder) their compatibility. The intuitive and sensitive crab can help teach the too-often critical goat how to forgive themselves. Opposite zodiac signs may be able use their strengths to tend to each other’s weaknesses. In this way, Cancer and Capricorn complement each other very well.

Not Just Your Sun Sign

While your sun sign makes up your core personality, other signs in your natal chart also help to determine romantic compatibility. For instance, your moon and Venus sign play important roles as well. A person’s moon sign represents the deepest, hidden parts of themselves. So, if you two have the same moon sign or your moon signs are in the same element (earth, air, fire, and water), then you’ll likely have a natural emotional connection. And if your partner’s moon sign is the same as your sun sign (or vice versa), then you’ll probably also have a deep emotional bond too. If your moon is in the sign of Leo, you may crave the spotlight and be literally beaming with optimism. You may pair well with a person whose moon, sun, or Venus sign is in Aries, Sagittarius, or Leo.

Your Venus sign, on the other hand, demonstrates how you love and approach relationships. It determines your romantic values, how you show affection, and where you find pleasure in life. That’s because planet Venus is the ruler of love and pleasure. If your Venus is in air sign Aquarius, you may have a more laissez-faire attitude in your romantic affairs. You’re best paired with other air Venus signs like Gemini and Libra. If your Venus sign is in sensual, pleasure-seeking Taurus, you may appreciate lots of generosity in your relationship and have no issue with public displays of affection. Your best matches are typically with fellow earth signs Capricorn, Virgo, and, of course, Taurus.
