How to read a birth chart

A birth chart looks complicated, but it is built from just four ingredients: planets, signs, houses and aspects. Here is a simple, step-by-step way to start reading your own.

The full deep dive

The chart is a map of the sky

A birth chart (or natal chart) is a map of the sky at the moment and place you were born, drawn as a wheel. The outer ring shows the twelve signs; the inner sections are the twelve houses; the symbols are the planets; and the lines across the middle are the aspects.

A five-step way in

  1. Start with your big three. Find your Sun, Moon and Rising sign. These give the outline of your personality. See Your big three.
  2. Look at the balance of elements. Count how many planets are in Fire, Earth, Air and Water signs. A lot of one element is a strong theme; a missing element is something you may seek in others. See Fire, Earth, Air and Water.
  3. Notice busy houses. Several planets in one house show an area of life that matters a great deal to you. See The twelve houses.
  4. Find the closest aspects. The tightest angles between planets are the loudest conversations in your chart. See The major aspects.
  5. Put it into a sentence. Planet (what) + sign (how) + house (where). “My Mars (drive) is in Capricorn (patient and ambitious) in the tenth house (career).”

Don’t try to read it all at once

Even professional astrologers take a chart one piece at a time. Start with what interests you, and let the rest unfold. Starlight’s First Timers reading explains each part as it goes.
