What Is Chart Type in Astrology? Read Astrological Chart
Walk into any conversation about astrology and someone will ask you: “What’s your rising sign?” Before you can answer that, you need to understand your chart. But the bigger question most people never get to ask is this – what is chart type in astrology, and does it change what the chart actually tells you?
The answer is yes. Profoundly so. The chart type determines the visual format, the reading direction, the fixed and moving elements, and ultimately how easily an astrologer can extract insights from it. Two astrologers can look at the same planetary data and arrive at different levels of precision – purely because of chart type.
This guide covers every major chart type across Vedic and Western astrology. It explains how to read each one, what divisional charts are, and how to finally understand your own birth chart with confidence.
What Is a Birth Chart in Astrology and Why Does Format Matter?
A birth chart – also known in Indian etymology as the Janam Kundali – captures the exact astronomical locations of stars and planets at the precise moment of an individual’s birth. It is a snapshot of the cosmic energy present when you entered the world and is thought to stay with you throughout your life.
Every chart contains the same core data: the twelve houses, the nine or ten planets, the twelve zodiac signs, and the Ascendant or Lagna. What changes between chart types is how this information is visually organised and read. There are different types of astrology charts – they have different shapes, but they all say the same thing. The idea behind these charts is to tell people how to manage their lives. Each shape is different, but the contents are the same.
That said, format is not trivial. The simplicity of the North Indian horoscope becomes very visible when it comes to divisional charts. In Vedic astrology, the importance of the divisional chart is very high. Choosing the right chart type makes the difference between clarity and confusion – especially when working with the more advanced layers of Vedic analysis.
The Four Major Astrology Chart Types
1. North Indian Chart – The Diamond Format
The North Indian chart is the most widely used format across India, particularly in Hindi-speaking states. Its immediately recognisable feature is its diamond-shaped grid.
The North Indian Kundali has diamond-shaped boxes to mention the houses and signs. According to the North Indian style Kundali, the houses are assumed to be fixed. They remain the same throughout, once the Kundli is prepared after the birth of a child.
The Ascendant is always the focus of the Kundli, and the Lagna is shown in the diamond box that is the topmost in the chart. The other signs take their position in sequence following the Ascendant, and the astrological signs are read in the anti-clockwise direction, left to right.
Where you see “Lagna” in the top diamond, that is synonymous with “rising sign” or “ascendant”. Whatever number you see in that top diamond will represent which sign was on your Ascendant at the moment of birth. You then count counter-clockwise to learn which signs govern which house.
This fixed-house structure is one of the North Indian chart’s greatest practical advantages. In the North Indian horoscope format, the Lagna is always the same house, and the Rasis will change. This means any astrologer can immediately locate the first house, the seventh house, and all Kendras without needing to reorient themselves for every individual chart.
In some ways Vedic astrology keeps things simpler. Instead of learning symbols, you just need to follow numbers – at least in the North Indian chart – and know the zodiacal order of the planets.
2. South Indian Chart – The Fixed-Sign Grid
The South Indian chart uses a rectangular grid format. The South Indian chart is designed in a symmetrical square shape, and the Ascendant is marked with two lines at the upper corner. If the Ascendant is Pisces, then the next sign is Aries, followed by Taurus, Gemini, and so on clockwise.
The key difference from the North Indian format is exactly what is fixed and what moves. In the South Indian chart, the signs stay fixed and you read clockwise. In conclusion, the biggest difference between the South Indian and North Indian charts is that in the North Indian chart, the houses stay fixed and you read counter-clockwise, while in the South Indian chart, the Rasis remain fixed and the Lagna will change.
Because the zodiac signs occupy fixed positions in the grid, the South Indian chart is excellent for observing planetary sign placements at a glance. It is particularly popular in Karnataka, Tamil Nadu, Andhra Pradesh, and Kerala.
However, due to the static nature of the Rasis in the South format, it can be difficult to understand the placement, aspect, and conjunction of planets in divisional charts. In the North format, it is very easy to detect patterns – such as a career promise in the government sector – in divisional charts as well.
3. East Indian Chart – The Hybrid Format
The East Indian Kundali is a combination of the South Indian and North Indian Kundali formats. Like South Indian, the astrological signs are fixed in East Indian Kundali. And like North Indian Kundali, the East Indian chart is read from right to left. Houses in the East Indian Kundali chart change according to the position of the Ascendant, and there are no borders to define the shape of the East Indian Kundli chart.
This format is common in West Bengal, Odisha, and parts of Northeast India. It is less frequently encountered by practitioners trained in either the northern or southern tradition, but it carries the same planetary data as both.
4. Western Circular Chart – The Natal Chart
Most Western astrologers use a circular format birth chart. This is not used in Jyotish. The two main types of chart formats used in Vedic astrology are the North Indian and South Indian systems.
The Western chart is in circle format, and the Ascendant is always on the left side, with the Rasis moving in an anti-clockwise direction. The entire zodiac wheel is 360 degrees, and the houses are divided equally into 30 degrees. The chart has two main points: Imum Coeli (IC) and Medium Coeli (MC). The IC comes in the fourth house, and the MC comes in the tenth house. The advantage of this format is that planets are shown at their exact degree.
In Western Tropical astrology, charts are pie-shaped. To read the chart, you need to learn both the symbols for the signs and the planets – otherwise you will not be able to make sense of it.
The Western chart excels in showing planetary degrees with visual precision. It is also the format used for progressions, solar arcs, and synastry overlays – techniques central to Western astrological practice.
How to Read Your Astrology Chart: The Core Elements
Regardless of chart type, every astrology chart contains five foundational layers. Understanding these layers is the foundation of knowing how to read your astrology chart.
Layer 1 – The Ascendant (Lagna). This is the zodiac sign rising on the eastern horizon at the exact moment of your birth. It defines the first house and anchors the entire chart. Every prediction starts here.
Layer 2 – The 12 Houses. Each house governs a specific area of life. The 1st house represents identity and body. The 4th rules home and mother. The 7th governs marriage and partnerships. The 10th covers career and public life. The 12th rules liberation, isolation, and foreign lands.
Layer 3 – Planetary Placements. Each of the nine planets (seven classical planets plus Rahu and Ketu in Vedic astrology) occupies a specific house and sign. Their placement determines the energies influencing each life domain.
Layer 4 – Aspects and Conjunctions. Planets influence each other through aspects – either by occupying the same house (conjunction) or by casting their gaze across the chart according to specific rules. In Vedic astrology, all planets aspect the 7th house from their position. Mars, Jupiter, and Saturn have additional special aspects.
Layer 5 – Yogas. Yogas are planetary combinations that produce specific results. Raja Yogas indicate authority and success. Dhana Yogas bring financial prosperity. Parivartana Yogas create powerful exchange relationships between planetary rulers.

What Are Divisional Charts in Astrology?
The birth chart – or D-1 Rashi chart – is the beginning, not the end. It gives the broad strokes of a person’s life. While the D-1 chart uncovers the overall theme of a person’s life, hinting towards their struggles and upcoming gains, the divisional charts give final details about these subtle layers.
In astrology, apart from the main natal chart called D-1, divisional charts are used to read the hidden layers about specific areas of life. These are sub-charts that uncover domains like your spiritual path, success, profession, marital life, children, parents, and much more.
The divisional charts are calculated by dividing each sign of the zodiac into smaller parts. For example, the D-9 or Navamsa chart is obtained by dividing each sign into 9 equal parts of 3 degrees 20 minutes each. Similarly, the D-10 or Dashamsa chart is obtained by dividing each sign into 10 equal parts of 3 degrees each.
Traditionally, 16 primary divisional charts known as “Shodashvarga” are used for detailed analysis in Vedic astrology. Advanced classical textbooks have mentioned up to 60 divisional charts that can uncover the tiniest detail about a person’s life.
Think of divisional charts as a microscope layered over the telescope of your birth chart. The birth chart reveals the landscape. Divisional charts reveal the terrain.
How to Read Divisional Charts in Vedic Astrology: The Key Charts
D-1 – The Rashi Chart (Birth Chart)
The Rashi chart, also known as the Lagna chart, is the primary chart in Vedic astrology. It represents the native’s Ascendant or Lagna and provides a comprehensive overview of the individual’s life, personality, and characteristics. All divisional charts derive from this foundation.
D-2 – The Hora Chart (Wealth)
The Hora chart focuses on wealth and financial matters. It reveals insights into the native’s financial prosperity, assets, income sources, and financial stability. This is the first divisional lens to examine when assessing a person’s potential for wealth accumulation.
D-3 – The Drekkana Chart (Siblings and Courage)
The D-3 chart, or Drekkana chart, divides each zodiac sign into three parts and is used to analyse one’s siblings, courage, and communication skills. It also shows how well one can take initiative and overcome challenges.
D-7 – The Saptamsa Chart (Children)
The D-7 chart, or Saptamsa, is used to assess matters related to children, fertility, and progeny. It divides each sign into seven parts and helps predict happiness from children and parenting experiences.
D-9 – The Navamsa Chart (Marriage and Soul)
The Navamsa is arguably the most important divisional chart after D-1. Navamsa means Nava Amsa – Nava means ninth and Amsa means division. This is the 9th division of a sign, also known as the D9 chart. The 9th house indicates fortune or Bhagya in Vedic astrology, which is why the Navamsa is sometimes called the chart of Fortune, or Bhagyamsa.
Any planet debilitated in the Rashi chart but exalted in the Navamsa will give the result of exaltation. But a planet exalted in the Rashi chart and debilitated in the Navamsa will give results of debilitation. This principle alone makes the Navamsa essential for any serious prediction.
For specific marriage timing guidance, the VAMA marriage prediction guide explains how the D-9 Navamsa interacts with Dasha periods to reveal when relationships will materialise.
D-10 – The Dashamsa Chart (Career)
Dasamsa gives clues to the way of livelihood, power, and authority. We have to see the 10th house and 10th lord from the Ascendant and the Moon sign in the D-10 chart. This is the essential chart for career direction, professional reputation, and public achievement. No career prediction is complete without referencing the D-10.
D-12 – The Dwadasamsa Chart (Parents)
The Dwadasamsa chart pertains to the native’s parents. It provides information about the relationship with parents, their influence, and potential events involving them.
How to Understand Birth Chart Astrology: A Practical Reading Framework
Understanding your birth chart does not require years of study. It requires a clear framework. Here is where to start.
Step 1 – Identify your Lagna (Ascendant). This tells you the lens through which you experience life. Every planet in your chart is interpreted relative to this point.
Step 2 – Locate your Moon sign. In Vedic astrology, the Moon sign carries enormous weight for emotional life, mental patterns, and the Dasha cycle that governs your timing.
Step 3 – Find where each planet sits. Note the house and sign for each planet. Which houses are occupied? Which are empty? Strong, occupied houses become the active arenas of your life.
Step 4 – Identify strong and weak planets. Planets in their own sign or exaltation are strong and deliver their best results. Debilitated or combust planets require careful analysis – though principles like Neecha Bhanga can reverse debilitation.
Step 5 – Cross-reference with the Navamsa. Once you have read the D-1, open the D-9. How does the same planet appear in the Navamsa? Does its strength improve or weaken? This determines the actual lived experience behind the birth chart’s promise.

North Indian vs South Indian vs Western: Which Chart Type Should You Use?
Each chart format is just a different way of representing the same information. The charts seem completely different but both contain the same astrological data.
The North Indian format is recommended for beginners and for divisional chart analysis – its fixed-house structure makes it easier to see patterns across D-1, D-9, and D-10. The South Indian format suits those who prefer visual sign clarity. The Western circular chart is ideal for psychological analysis, degree-level precision, and relationship synastry.
There is no wrong choice. The right chart type is the one your astrologer reads best and the one that allows you to most clearly see the map of your life.

Conclusion: Your Chart Is a Living Document
Every chart type – North Indian, South Indian, East Indian, Western – is a different window looking at the same sky. What matters most is not the format but the depth of analysis brought to it. A skilled astrologer using the North Indian format with divisional charts will deliver far more precision than a cursory sun-sign reading in any format.
The birth chart is not a prediction. It is a map. The divisional charts are the legend that makes the map readable. Together, they reveal your dharma, your karma, and your potential.

Frequently Asked Questions
Q1. What is chart type in astrology?
Chart type in astrology refers to the visual format used to represent a birth chart. The four main types are the North Indian diamond format, the South Indian rectangular grid, the East Indian hybrid format, and the Western circular natal chart.
All four contain the same planetary data but organise it differently – affecting readability, reading direction, and suitability for different types of analysis.
Q2. How do I read my astrology chart?
Start with the Ascendant or Lagna – the zodiac sign on the eastern horizon at your birth. This anchors the twelve houses. Then identify each planet’s house and sign placement, note strong and weak planets, check for major yogas, and cross-reference with the Navamsa (D-9) chart.
In the North Indian format, the Ascendant is always in the top diamond and houses are read counter-clockwise.
Q3. What are divisional charts in astrology?
Divisional charts – also called Varga charts – are sub-charts derived from the main birth chart (D-1) by dividing each zodiac sign into smaller equal parts. Each division corresponds to a specific area of life. The D-9 Navamsa reveals marriage and spiritual life. The D-10 Dashamsa reveals career. There are 16 primary divisional charts used in classical Vedic astrology.
Q4. How do you read divisional charts in Vedic astrology?
Identify the relevant divisional chart for your question – D-9 for marriage, D-10 for career, D-7 for children. Locate the relevant house and its lord in the divisional chart. Compare the planet’s placement in the divisional chart with its placement in the D-1 birth chart.
A planet debilitated in D-1 but exalted in the Navamsa performs well. The D-chart placement takes precedence for the specific life area it governs.
Q5. How do you read a Western astrology chart?
A Western chart is circular, with the Ascendant on the left. Signs and planets are represented by symbols. The Ascendant moves anti-clockwise around the wheel. Planets show their exact degree positions. Key points include the IC (4th house cusp) and MC (10th house cusp). Reading a Western chart requires knowing both planetary and zodiac sign glyphs.
Q6. Is the North Indian or South Indian chart format better?
For divisional chart analysis and pattern recognition, the North Indian chart’s fixed-house structure is generally more practical. For seeing exact zodiac sign placements at a glance, the South Indian fixed-sign format has advantages.
Q7. What is the most important divisional chart in Vedic astrology?
After the main Rashi chart (D-1), the Navamsa (D-9) is considered the most important divisional chart. It modifies the strength of all planets from the birth chart and is essential for marriage, relationship, and spiritual analysis. The Dashamsa (D-10) is the second most critical, governing career and professional achievement. No serious Vedic prediction is made without consulting both.
