Guide: Golden Ratio

What it does

Divides T into T/φ and T − T/φ.

How to use it

Enter total length, then split.

Formula

Long = T/φ; short = T − long; φ = (1+√5)/2.

Example

100 units → long ≈ 61.8, short ≈ 38.2.

FAQs

Is φ used in nature everywhere?

Often overstated; still a useful design proportion.

Which segment is “long”?

Typically the longer segment relates to the whole as φ:1 in classic constructions.

UI spacing?

Use rem/px consistently after you compute the split.
