[[File:FakeRealLogSpiral.svg.png|thumb|Approximate and true golden spirals: the green spiral is made from quarter-circles tangent to the interior of each square, while the red spiral is a golden spiral, a special type of logarithmic spiral. Overlapping portions appear yellow. The length of the side of a larger square to the next smaller square is in the golden ratio.]] | [[File:FakeRealLogSpiral.svg.png|thumb|Approximate and true golden spirals: the green spiral is made from quarter-circles tangent to the interior of each square, while the red spiral is a golden spiral, a special type of logarithmic spiral.

In geometry, a [[Golden Spiral]] is a logarithmic spiral whose growth factor is φ, the [[Golden Ratio]]. That is, a golden spiral gets wider (or further from its origin) by a factor of φ for every quarter turn it makes.<ref>[https://en.wikipedia.org/wiki/Golden_spiral Golden | In geometry, a [[Golden Spiral]] is a logarithmic spiral whose growth factor is φ, the [[Golden Ratio]].
