Golden Ratio Calculator

Simply enter any measurement (width, height, or size) in the base measurement field. The calculator instantly shows you both the larger and smaller proportions based on the golden ratio. You can adjust decimal places using the +/- buttons and copy results to your clipboard.

The golden ratio (φ ≈ 1.618) is a mathematical proportion found throughout nature and art. When a line is divided according to this ratio, the relationship between the parts creates visually pleasing proportions. It's been used in architecture, art, and design for thousands of years because it naturally appeals to the human eye.

Use the larger proportion for your main content area and the smaller for sidebars or secondary elements. For typography, set your body text size, then use the golden ratio to determine heading sizes. In photography, position key elements along golden ratio lines instead of the traditional rule of thirds.

The calculator works with any unit of measurement - pixels, inches, centimeters, points, or any other unit. Since it calculates proportional relationships, the unit doesn't matter. Just ensure you apply the same unit to your results.

You'll find it in nautilus shells, flower petals, pine cone spirals, and even human body proportions. In design, it appears in logos like Apple and Twitter, classical architecture like the Parthenon, and famous artworks like the Mona Lisa. Many modern websites and apps also use golden ratio proportions in their layouts.

While the golden ratio creates pleasing proportions, it's a tool, not a rule. Use it as a starting point for layouts and proportions, but don't feel constrained by it. Sometimes other ratios or proportions might work better for your specific design goals or brand requirements.
