text: Gemini is an air sign and thus a perfect match for Gemini would be considered other air signs. However Fire signs also match up well with Gemini and despite what you may have heard, Sagittarius (which is Gemini's Polar Opposite) is a GREAT match if you can learn to make your differences work for you. However be careful with aries and leo who are too arrogant for the tastes of geminis (and most other people too, lol). \nLibra and aquarius are air signs and thus considered perfect matches for gemini. Libras are the only ones who are capable of bending enough for stubborn geminis. Aquarians tend to be a little too suspicious for anything to really come about with gemini. \n\nAll of this is generally speaking of course. There are plenty of websites and books you can consult but keep in mind that everything you read will be generally speaking. Astrology tells you a lot about basic personality but it is highly complex science.
