Divide a length into two parts using phi.
Last updated: June 2026 | By Patchworkr Team
Choose whether you want to enter the total length, longer part, or shorter part.
Phi is the golden ratio, about 1.618.
The longer part divided by the shorter part is approximately phi.
Divide 100 using the golden ratio.
1. Total = 100
2. Longer = 100 / phi
3. Shorter = Total - Longer
Final answer: 61.8034 and 38.1966
What does the total mode do?
It treats the input as the total length and splits it into golden parts.
Can I enter a negative number?
No. Golden ratio parts are intended as non-negative lengths here.
Why is the ratio approximate?
Phi is irrational, so the calculator rounds for display.
Does the ratio always stay the same?
Yes. The longer part divided by the shorter part stays close to phi.
