When I was a kid, my mom (who knew a bit about astrology) would explain the signs to me, using the personalities of people I knew as examples. I was a shy Pisces, but my brother was an outgoing Gemini. “He’d make friends with the Devil!” she’d say. It’s true that Geminis (for the most part) can get along with anyone—or at least make it seem like they can get along with anyone. But when it comes to Geminis and their siblings, there are some pairings that just make more sense. Here’s our definitive ranking on Gemini sibling compatibility.
Gemini Sibling Compatibility, Ranked from ‘Can’t-Leave-These-2-Alone to Joined-at-the-Hip’
12. Scorpio (October 22 – November 21)
Geminis have a lot of energy and more than anything, they love to have fun. Leave it to Gemini to get everyone in the family screaming ‘80s pop ballads at the family holiday party or to show up to what was supposed to be a casual happy hour ready to start a badminton tournament. Scorpios, on the other hand, like to keep a certain amount of distance from their siblings, never wanting to reveal too many of their secrets. Though these two are both extremely loyal, they butt heads over how they show that loyalty.
11. Taurus (April 20 – May 20)
Gemini and Taurus are both big softies when it comes to their families. But because Gemini can be so competitive, this can lead to fights over who’s the best sibling. While Taurus cooks the perfect five course meal for their parents’ anniversary, Gemini, not one to be shown up, is stealing the show by cracking jokes around the dinner table. Taurus finds Gemini’s constant need to “lighten the mood” grating, and Gemini wishes that Taurus didn’t take everything so personally.
10. Sagittarius (November 22 – December 21)
Though Gemini and Sagittarius are the most alike of all opposite signs, as siblings they tend to clash. It might be because the two of them are so similar that their differences are glaring. As much as Geminis love to goof around, they also love to organize. Geminis are the ones sending around spreadsheets to plan Thanksgiving potlucks and volunteering to help their siblings move. Sagittarius, on the other hand, likes to take a less is more approach to sibling bonding. Though Saggittarians always dish out the best advice, they can also be aloof which hurts Gemini’s feelings.
9. Cancer (June 21 – July 22)
Cancers are the emotional regulators of the zodiac, always making sure everyone is fed, watered, and allowed to cry if they want to. As siblings, Gemini and Cancer have a lot to learn from each other as they handle life in completely different ways. Growing up, Cancer likely resented Gemini for being too reckless while Gemini wished they had some of Cancer’s discipline. Through accepting their differences though, Cancer eases up on the rules and Gemini discovers that structure isn’t so bad!
8. Capricorn (December 22 – January 19)
Geminis live in the moment while Capricorns are always planning ahead. As kids, Capricorn was probably the top student in the class while Gemini was more of the class clown. As adults, Capricorn feels like Gemini (who has a much more vibrant social life) is always leaving them on read. Both are super smart though! These two find common ground when they nerd out over shared interests.
7. Virgo (August 23 – September 22)
Virgo and Gemini are both ruled by Mercury, planet of wit, communication and technology. As siblings, these two love to make things together. This is a combo that could start anything from a sibling garage band to a successful tech startup. Both are very analytical and Gemini thrives when under the direction of practical Virgo. Though these two rarely clash, they do when Virgo feels like Gemini is giving away too many of their shared secrets.
6. Pisces (February 19 - March 20)
Mercurial Geminis love details while jovial Pisces are all about the big picture. This sibling pairing loves to live the high life together as both have classy, expensive taste. During childhood, these two likely shared a lot of mutual friends and spent time playing sports or making art together. As adults, Gemini and Pisces are the two who always bring the family together as both are very steadfast and sentimental (despite their sometimes flaky exteriors).
5. Gemini (May 21 - June 20)
It’s double trouble (or, I guess, quadruple trouble!) when two Geminis get together. These two understand each other on a soul level, and unlike other sign pairings are OK with their sibling falling off the grid or missing a few texts. Sometimes you have to do what you have to do! The only issue this double Gemini pair might run into is what to do when they like different things. Geminis get obsessed with the things they love, so if one is a philosophy geek and the other enjoys more outdoor activities, they may never see each other.
4. Libra (September 23 – October 21)
Libras tend to be the mediators in every situation so as siblings, they are kind, understanding and don’t take things too seriously. Libras tend to have a more “free -ange” approach to their family relationships where they treat childhood besties like cousins and bunkmates from summer camp like honorary siblings. Geminis love that Libra has an open mind allowing these two to have an easy relationship. Not everything has to be super deep!
3. Leo (July 23 – August 22)
Gemini and Leo are both big personalities. And though in other kinds of relationships (especially romantic or coworkers) these two might be too much for each other to handle, as siblings, they’re usually on the same page. More than siblings, they’re best friends! Both are always down to adventure together and make each other a priority even if they live in faraway cities or follow totally different career paths.
2. Aquarius (January 20 – February 18)
Because Aquarians have a perpetual wise-old grandma energy, Geminis tend to look up to their Aquarius siblings (even if the Gemini happens to be older). These are the cool siblings who everyone else wants to be. Together Gemini and Aquarius embrace all kinds of strange interests from watching Ancient Aliens to road tripping to every diner that serves a certain kind of onion rings to going to cosplay conventions together. Gemini brings out Aquarius’ playful side while Aquarius makes Gemini feel like the smartest person in the room.
1. Aries (March 21 – April 19)
Gemini and Aries are the ultimate goofball sibling pair. These are the type of siblings who coincidentally bleach their hair blonde on the same day without discussing it in advance. They’re equally chaotic and in sync! Though Aries can sometimes be more fiery or aggressive than Gemini, these two always end even their biggest fights in laughter (and also, a sing-a-long).
