North vs South Indian Chart Style: A Visual Guide
Show a North Indian astrologer a South Indian chart and watch the brief, comical confusion — then watch them read it perfectly anyway. India's three classical chart formats look nothing alike but say exactly the same thing. Here's how to read all three, why they differ, and which one you'll encounter where.
North Indian: the diamond
The North Indian chart is a square divided by diagonals into twelve diamond-shaped houses. The ascendant's sign always sits in the top-center diamond; the other signs follow counterclockwise in fixed order. Houses are fixed in position — the 1st house is always top-center, the 7th always bottom-center — while the signsrotate depending on the ascendant. Once you know the layout, the eye goes straight to the house: Mars in the top-center diamond is Mars in the 1st house, whatever sign it's in.
This house-fixed design makes yogas and house-based patterns jump out visually — which is presumably why it evolved in the region most focused on Parashari house analysis. See it rendered for your own chart at kundli.site/kundli.
South Indian: the grid
The South Indian chart is a 4×4 square grid (corners removed, leaving twelve boxes). Here the signs are fixed in position — Aries always top-left-center, Taurus next clockwise — while the houses move: the box containing the ascendant sign is the 1st house. It's the mirror image of the North Indian logic: sign-fixed rather than house-fixed.
South Indian astrologers, often more nakshatra-focused, find this layout natural — the sign's position never moves, so planetary relationships by sign are instantly visible. The tradeoff: house patterns require a moment's orientation ("where's the ascendant?") that North Indian readers never need.
East Indian: the variant
The East Indian (Bengali/Oriya) chart resembles the South Indian grid with its own arrangement conventions. Less common outside its region, but complete and traditional. If you receive a chart from a Kolkata astrologer, this is likely what you're looking at.
How to read any of them
- Step 1: find the ascendant mark (usually "Lg" or "As"). Everything orients from here.
- Step 2 (North Indian): houses are fixed — read planets by diamond position. Signs are written inside each diamond (often as numbers 1-12).
- Step 2 (South Indian): signs are fixed — find which box holds the ascendant sign; that's house 1, and houses proceed clockwise.
- Step 3: verify against the planet table. Every traditional chart comes with (or should come with) a written list of planetary positions — the diagram is the overview, the table is the authority.
Frequently asked questions
Which chart style is more accurate?
They show identical data — same planets, same signs, same houses. The difference is purely visual layout. Accuracy lives in the calculation, not the diagram. Use whichever your teacher or region uses.
Why are there different chart styles?
Regional manuscript traditions. North India developed the diamond (kendra) layout, South India the square grid, East India its own variant. Each region's astrologers learned to read their local format, and the formats stuck through centuries of use.
Can I convert between North and South Indian charts?
Yes — they're the same data drawn differently. Any competent astrologer reads both. Software typically lets you toggle the display style without recalculating anything.
Which style does kundli.site use?
We render the North Indian diamond style by default as it's the most widely recognized, but the underlying data is identical regardless of display format.
The bottom line
Same sky, three frames. Learn the one your region uses, recognize the others on sight, and never mistake the frame for the picture — the planets don't care which boxes you draw around them.
