Formula breakdown

Formula

φ = (1 + √5) ÷ 2; longer = side × φ, shorter = side ÷ φ

= 1618.0339887499

Note

Simplified model: these are standard prepress and typographic relationships computed on nominal values. Real press bulk, paper caliper and shrinkage, ink limits for a given profile, font metrics and binding allowances vary by supplier and by job, so confirm with your printer and a proof before going to press.

Frequently asked questions

What is the golden ratio, and what number does this calculator use?+

The golden ratio is approximately 1.618, a proportion long associated with visually pleasing composition in art, architecture, and design. The calculator multiplies or divides your known dimension by this value to find its golden-ratio counterpart.

How do I use the result — is the longer or shorter side 1.618?+

If you have the shorter side, multiply it by 1.618 to get the longer side; if you have the longer side, divide by 1.618 to get the shorter side. The ratio between them should always equal roughly 1.618:1.

Is the golden ratio scientifically proven to be more attractive?+

No — it's a long-standing design tradition and aesthetic heuristic, not a proven law of perception; rigorous studies on 'golden ratio' preference in faces and layouts have produced mixed and often unconvincing results. Treat it as one useful proportion to try, not a guaranteed formula for beauty.

Where is the golden ratio commonly applied in design?+

Common uses include cropping photos, sizing text columns relative to margins, proportioning logo elements, and laying out page grids, where a 1:1.618 relationship between two measurements can guide a natural-feeling division of space.

Can I apply the golden ratio to more than two dimensions at once?+

Yes, through a golden spiral or repeated subdivision, where each new section relates to the previous one by the same 1.618 factor. This calculator handles the basic two-dimension case; extending it further is a manual repeated application of the same ratio.
