Chart Shape Calculator
The overall shape your planets make around the wheel — whether they bunch up, fill one half, or scatter everywhere — is a big-picture signature of your personality. These are the classic "Jones patterns." This calculator finds your chart shape from the spread of your ten planets and explains what it means.
Frequently asked questions
What are chart shapes (Jones patterns)?
Chart shapes, introduced by astrologer Marc Edmund Jones, classify a birth chart by how the planets are distributed around the wheel. The main patterns are the Bundle, Bowl, Bucket, Locomotive, Seesaw, and Splash. The shape gives a quick read on your temperament — how focused, self-driven, balanced, or wide-ranging your energy tends to be.
How is my chart shape calculated?
We take the positions of your ten planets (the Sun through Pluto), sort them around the zodiac, and measure the gaps between them. The size of the largest empty gap — and how many large gaps there are — determines the pattern: a tight cluster is a Bundle, planets filling half the wheel make a Bowl, an even spread is a Splash, and so on. We state the method and show how your chart fits.
Do I need an exact birth time for my chart shape?
Usually not. Chart shapes are based on the planets, which move slowly enough that your birth date and place almost always pin the pattern. The Moon is the only fast-moving body, so only charts where it sits right at the edge of a gap are time-sensitive — and even then the shape rarely changes.
