Sister signs are positioned opposite each other on the zodiac wheel. These signs are technically polar opposites, but their differences complement each other, so they tend to be pretty compatible in friendship and romance. They have a yin-yang dynamic, which usually makes for a balanced and harmonious connection. The two members of each pair also have complementary elements (either earth and water or fire and air).^{[1]

Sister signs share the same modality, which increases compatibility. Each pair is made up of two cardinal signs, two mutable signs, or two fixed signs. The modalities in astrology represent specific qualities, so the shared modalities between sister signs lead to a sense of understanding and commonality between them. Here’s a breakdown of each:
- Cardinal sign pairs (Capricorn & Cancer, Aries & Libra) begin a new season, so they’re dynamic and bold.
- Fixed sign pairs (Taurus & Scorpio, Leo & Aquarius) carry the middle of the season, so they’re sturdy and stable.
- Mutable sign pairs (Gemini & Sagittarius, Virgo & Pisces) fall at the end of the season, so they’re flexible and good with change.^{[5]

1
Aries and Libra are both known for being extroverted leaders. Both signs tend to be popular and well-liked, but for slightly different reasons. Aries is all about individual expression and boldness, so others admire and look up to them. Libra, on the other hand, has a friendly and personable nature that makes it easy for them to connect with people. Nevertheless, this pair bonds over their shared confidence and sociability, and as Cardinal signs, they’re both leaders and initiators.^{[6]

- Elements: Fire (Aries) and Air (Libra)
- Modality: Cardinal

Pros: This pair works because each has something the other lacks. Fire sign Aries is assertive and a bit impulsive—they’re not afraid to speak up and go after what they want.^{[7]

Research source} Air sign Libra, on the other hand, is peacemaking and diplomatic, with a special talent for mediating arguments and bringing people together.^{[8]

- In other words, Aries brings boldness and strength, and Libra complements this with collaboration and people skills. When these two different types of leadership come together, there’s nothing this pair can’t achieve!

Cons: They approach decisions differently, which can be a challenge. Aries isn’t one to sit back and ponder their choices—they charge into a situation head-first, guided by their confidence and intuition. Libra, on the other hand, is all about weighing the options carefully and coming to a logical conclusion. At times, Aries may become impatient with Libra’s indecisiveness, and Libra may become stressed out by Aries’ tendency to act before thinking.^{[12]

- To overcome this: Aries and Libra will need to focus on being patient with each other and opening their minds to the other’s perspective.
- There are times when it’s best to be decisive and bold, and times when it’s necessary to work through things rationally before taking action.
- If Libra and Aries can learn this and recognize the value in the other’s position, they can truly push each other to be better people and achieve their goals.^{[13]

Cons: This pair may struggle with stubbornness and jealousy. The similarities that make Taurus and Scorpio compatible also present a few challenges.

They can also be possessive and distrustful, which can lead to issues with jealousy, especially in romantic relationships.^{[18]

- To overcome this: Both Taurus and Scorpio must learn to compromise and keep their stubbornness in check. Instead of putting up walls when they disagree, they’ll need to talk things out and be open to each other’s perspectives.
- They’ll also need to work on their trust issues individually, so that they can give each other the benefit of the doubt and avoid unwarranted jealousy.
- Ultimately, if Taurus and Scorpio keep these things in mind, they make a super solid match for friendship and beyond.^{[19]

Virgo can be a bit critical, but Pisces is good at letting things go. Although Virgo is a fluid sign, they’re also prone to micromanaging. Luckily, these things are water off a duck’s back for Pisces, meaning they’re able to let Virgo’s little criticisms roll off their back, rather than taking them personally.
3
Cons: Virgo’s rationality and Pisces’ emotionality may clash at times. Virgo values consistency and predictability, so Pisces’ shifting moods can definitely unsettle them. Pisces, on the other hand, is all about “vibes and instincts and feelings,” says Eyedealism, so they may find Virgo’s focus on logic and rationality frustrating.^{[40]

One big reason for this is the fact that sister signs share the same modality, which means they have a lot of shared traits. The cardinal sign pairs are natural leaders, the fixed signs are stable and trustworthy, and the mutable pairs are flexible and adaptable. With these commonalities, the sister sign pairs tend to understand each other instantly and feel safe around each other.

Are sister signs a good match?

This is likely because sister signs are opposites on the zodiac wheel and have opposite elements. In romance, opposites often attract, so sister sign pairs often feel magnetically drawn to each other. And, once they start a relationship, their complementary energies can make for very passionate and intense connections.
