Once you know your partner well enough to unabashedly ask for everything you need to draw up their birth chart, then beginners will want to focus on where each of the seven inner planets lies in both of your charts. That includes your Sun, Moon, Mercury, Venus, Mars, Jupiter, and Saturn placements (via Psychic Science). The Sun will illuminate just how temperamentally compatible you are, while the Moon indicates emotional suitability. Mercury measures intellectual rapport; Mars is physical compatibility,'and again, Venus is your romantic fit. Jupiter indicates ideological agreeability, and, finally, Saturn measures potential long-term unity. If you'd like, you can look at your Ascendant sign, which is social agreeability, just to be thorough.
When you understand what each planet indicates, it really helps you to understand why a full birth chart is an important tool for really finding out how compatible you are on all of the most important components of a relationship. These tools reflect exact planetary influences on individuals, and it is very unlikely that any two are completely identical.
So, study up on your birth charts, and find out the areas where your relationship could thrive or suffer. Remember, you have control over your actions. You still can make things work even if you're not totally compatible. If you know there are things that could be difficult points in the relationship, such as communication or romantic styles, just be aware of it.
