HOW IT WORKS
The calculator preserves your unit. Pixels remain pixels; millimetres remain millimetres. Whether you call it the golden mean, golden section or golden proportion, the same φ relationship is used at full numeric precision.
Longer = shorter × φ.
Shorter = longer ÷ φ.
The whole is divided into two golden-related parts.
