How to Read Your Birth Chart, Step by Step

What a birth chart is

In plain EnglishA birth chart is a snapshot of the sky from where you were born, at the minute you were born.

It’s drawn as a circle. The outer ring shows the twelve zodiac signs. The inner ring splits into twelve houses. Small symbols mark where ten planets (the Sun and Moon count as planets in astrology) were at the time. Lines through the middle connect planets that make an angle to each other.

It looks busy the first time. It stops looking busy once you know there are only four things to read: signs, planets, houses and aspects.

Step 1: Find your Big Three

In plain EnglishStart with Sun, Moon and Rising, because they cover most of what people recognize.

Your Sun sign is the one in the newspaper horoscope. Your Moon sign is where the Moon was when you were born, and it describes how you feel and what you need to settle. Your Rising sign (or Ascendant) is the sign on the eastern horizon at birth, and it describes how you come across at first.

Read all three together before you read anything else. A Sun in Scorpio with a Moon in Gemini and a Rising in Leo is a very different person than a plain Scorpio. We cover this in full in our guide to Sun, Moon and Rising.

Step 2: Learn what each planet does

In plain EnglishEach planet is a part of you, and the sign tells you its style.

The Sun is identity. The Moon is feeling. Mercury is how you think and talk. Venus is what you like and how you love. Mars is how you act and fight. Jupiter is where you grow, and Saturn is where you’re serious. Uranus, Neptune and Pluto move slowly and mark whole generations, so they matter most when they touch a personal planet.

To read a planet, put it in a sentence: “My Venus is in Taurus,” meaning “I love slowly and through the senses.” That’s already a reading.

Step 3: Place the planets in houses

In plain EnglishThe house tells you which part of life the planet works in.

Locate each planet’s symbol on the wheel and note which of the twelve slices it sits in. Venus in the 2nd house is about money and value. Venus in the 7th is about partnership. The Ascendant is on the left side of the wheel, where the 1st house begins, and the houses count counterclockwise from there. Our guide to houses explains all twelve.

If you don’t have a birth time, you can still read the signs and planets, but not the houses. We explain that in our guide to charts without a birth time.

Step 4: Look at the aspects

In plain EnglishAspects are the planets’ conversations, and the angle tells you the tone.

An aspect is an angle between two planets, measured in degrees around the circle. The main ones: a conjunction (0 degrees) fuses two planets together. A sextile (60) is a friendly opening. A square (90) is friction that pushes you to act. A trine (120) is ease. An opposition (180) is a pull between two poles.

Astrologers allow a few degrees of wiggle room, called an orb. Tighter is stronger. Many astrologers say that squares and oppositions are not “bad”: they often drive the most effort and growth. Others read them more cautiously, and the field is split.

Step 5: Put it together in one sentence

In plain EnglishA reading is a short sentence that joins a planet, a sign and a house.

Take the Moon. Say it sits in Cancer in the 10th house. Your reading: “My feelings (Moon) are tender and protective (Cancer) and show up in public life (10th house).” Add one aspect: if the Moon squares Saturn, “and I’m hard on myself about it.”

Do that for the Sun, Moon, Rising and any planet that is alone, tight to an angle or in a cluster. That’s a chart reading. Anything beyond that is detail.

What to watch for

In plain EnglishThe most useful reading focuses on patterns, not single items.

Look for a stellium, which is three or more planets in the same sign or house, because it shows where your attention piles up. Look at the balance of elements, since a chart heavy in water behaves differently from one heavy in earth. Notice a planet that rules your Rising sign, because astrologers call it the chart ruler.

Be careful of reading every line as a fact. A chart describes tendencies and themes, and two people with similar charts live different lives. Astrologers disagree on house systems, on which minor points matter and on how much of a chart is destiny, and it helps to hold it loosely.

Where to go next

In plain EnglishGenerate your chart, then read one placement at a time.

Use our birth chart tool to calculate yours with the real positions, and read the page for each sign it lists. Reading one planet in one sign each day is a better way to learn than trying to read the whole wheel at once.

A worked example

In plain EnglishHere is one planet read all the way through, so you can copy the method.

Suppose your Mercury is in Gemini in the 3rd house, trine Saturn. Mercury is how you think and talk. Gemini says it’s quick and curious. The 3rd house says it works in everyday conversation, writing and learning. The trine to Saturn says that speed has discipline behind it. In one line: you think fast, talk well and take what you say seriously. Do the same for your Venus, Mars and Moon and you’ve read the heart of the chart.
