What is a golden ratio calculator?
A golden ratio calculator applies φ (phi ≈ 1.618) to any number you give it, returning a longer dimension (value × 1.618) and a shorter dimension (value ÷ 1.618). Designers reach for this ratio because it produces proportions that feel naturally balanced — the same relationship found in art, architecture, and nature.
Use it to size headings against body text, set column widths, space UI elements, or lay out App Store screenshots. Start from any known measurement and the calculator gives you the harmonious partner value instantly, no manual maths required.
