Chart patterns
Grand cross
A grand cross is four planets arranged in two oppositions that also square each other, forming a cross across the chart. The four usually share a modality, so it combines the drive of a T-square with a second axis of tension pulling the other way. It is the most demanding of the common patterns, a chart carrying a lot of pressure at once, but also a great deal of stamina and drive once its forces are balanced.
A grand cross is the heaviest of the tension patterns, four planets locked into a square-cornered cross. It is really two T-squares sharing their arms, or two oppositions crossed at right angles, and it pulls a chart in four directions at once.
Four planets 90° apart with no empty leg
Four planets take up positions 90 degrees apart all the way around the wheel, so each one opposes the planet across from it and squares the two on either side. The result is a closed cross with no empty leg to drain the pressure, unlike a T-square. The four planets almost always share a modality, giving a cardinal, fixed or mutable grand cross, and that shared mode sets the theme of the strain.
Huge capacity held under constant tension
Tradition reads a grand cross as huge capacity held under constant tension. The person is credited with stamina, resourcefulness and the ability to carry a lot, but also warned about feeling boxed in and stretched across four competing demands. A cardinal grand cross is read as a crisis of action, a fixed one as a standoff of wills and values, a mutable one as a scramble of shifting directions. Integrated, it is a powerhouse; unintegrated, it can feel like being pulled apart. Astrologers often suggest working the pattern one arm at a time, since trying to satisfy all four points at once is what wears a person down.
A fixed cross in Taurus, Leo, Scorpio and Aquarius
Picture a fixed grand cross with planets in Taurus, Leo, Scorpio and Aquarius, each squaring its neighbors and opposing its partner. A reader might describe a clash of stubborn wills around security, pride, power and ideals, someone with tremendous staying power who has to learn when to give ground, since none of the four points will yield on its own.
Grand cross, T-square and grand trine
A grand cross is not a T-square; it has four planets and a closed shape rather than three and an open one. It is also the opposite of a grand trine in feel, all friction where the trine is all flow. And it is fairly uncommon, since four planets rarely align so precisely around the wheel.

FAQ
Frequently asked questions
What is a grand cross in astrology?
Four planets spaced 90 degrees apart, forming two oppositions that also square each other into a cross. It is essentially two T-squares sharing their arms, with no empty leg.
Is a grand cross rare?
Fairly. Four planets rarely line up so precisely, which is why a grand cross shows up far less often than a single square or a T-square.
What is a fixed grand cross?
A grand cross made of fixed signs, Taurus, Leo, Scorpio and Aquarius. It is read as a standoff of stubborn wills around security, pride, power and ideals.
