How We Calculate This

The golden ratio uses phi (φ = 1.6180339887) to create proportional divisions:

Division Points

Primary division = dimension / φ ≈ 61.8% of total

Secondary division = dimension - primary ≈ 38.2% of total

Phi Grid

The phi grid creates a 3x3 grid similar to rule of thirds but with the centre column and row narrower. The four intersection points serve as placement guides for key elements.
