Many things in the birth chart offer insight into compatibility and romance, and a person's "sign" is not the only contributing factor. I've provided the following list of signs which have traditionally been considered to be harmonious or inharmonious. Whether you are compatible with your same sign (for example, Aries with Aries) depends on how much you like yourself, since they'll share many of your traits, including the undesirable ones. Whether you can get along with your opposite sign (for example, Aries with Libra) depends on whether the two of you can allow each other to be opposites, rather than insisting your partner be more like you. Signs not listed at all do not significantly impact each other.
As you read this general list, please remember that you are not composed of all one "sign" and your Sun sign may be compatible with another's, while your Moons may be in signs that are incompatible. For best results, read the signs of your Sun, Moon, Mercury, Venus, Mars and Ascendant (if known). Since each planet in your chart, as well as its house placement and relationship to the other planets, reveals something about your overall personality, considering all these factors will give you a more accurate picture of your needs in relationships. If you don't know the signs these planets were in at the time you were born, you can order a birth chart on-line for $3 or a personalized report for $30.
