Golden Ratio Calculator

Enter one value and the calculator will automatically fill in the other to create a perfect golden ratio proportion.

The golden ratio (φ) ≈ 1.618 is a mathematical proportion found throughout nature and art.

Enter a value in either field to calculate the golden ratio proportion

How it works:

  • Enter a value in the shorter length field → the longer length is calculated as a × φ
  • Enter a value in the longer length field → the shorter length is calculated as b ÷ φ
  • The ratio b:a will always equal φ (1.618...)
  • Total length (a + b) is also in golden ratio with the longer segment (b)

This tool calculates the golden ratio for two numbers. It compares a shorter value with a longer one using a ratio of approximately 1.618.

What This Tool Does

The tool works when you enter a number in one of the input fields. It then computes the missing value. This follows a math rule seen in art and nature.

How to Use This Tool

Step-by-Step Instructions

Explanation of the Input Fields

The shorter length field is for the smaller measurement. The longer length field is for the larger number. Both fields need a positive number to work properly.

Understanding the Output

The result shows clear details:

Special Notes

Only positive numbers work. If you enter zero or a negative value, the tool will ask for a valid positive number. The tool recalculates as you type.

Common Use Cases

This calculator fits many projects such as:

Wrap-Up

Try the calculator to check if your measurements follow the golden ratio. Follow the steps to get clear results and practical numbers. Use it for art, design, or math projects.
