Golden Ratio Do It Yourself Projects

Golden Grid

If you have a printer and transparencies, you can print the “Golden Ruler”© grid below and use it to see the golden section and phi in various objects.  Simply hold the transparency in front of you and match the lines up to the object to see if its design is based on the golden section, as shown below.

Try the "Golden Ruler" grid on a transparency to see the phi or golden ratio / golden section proportions anywhere you choose.

Here’s a small sample grid or click on the Free Golden Ratio “Golden Ruler” Template below for a larger, printable version.

Golden Section Gauge

Make your own golden section gauge using the template below.  It will work best if you construct it from heavy cardboard stock or plastic.  Drill holes and place a brad at each of the indicated points.  When the gauge is adjusted the middle arm will always show the golden section or phi point between the two outer arms.

Note:  The dimensions listed actually represent the distances between the rivets and the tips, not the lengths of the pieces.  It’s best to think of the gauge conceptually as being made of very fine line segments connecting at golden section points. The actual length of piece AF is thus a little longer than the distance from the rivet at A to the tip at F in order to give the rivet some room to hold.  The tips of the gauge should all come together when it’s closed.

Note that some people call this a Fibonacci gauge, but the Fibonacci series (0, 1, 1, 2, 3, 5, 8, …) is a series whose ratios converge on the golden ratio as the series increases. I think it is more appropriately called a golden mean gauge or golden ratio gauge, as that is the precise ratio that it measures.

Dodecahedron / Icosahedron structure

You can make your own internal structure for a dodecahedron or icosahedron, both based on phi, using the template below:

    You people are great. Thank you so much for providing this information in such creative and understandable ways. Your site has been extra enjoyable at 2:45 am after working for days coding websites. I still don’t really “get it” but I will let my mind figure it out in its own time. Namaste.

    Thanks a Lot for providing such a wonderful tool..I also tried to make Golden Section Gauge but failed due to the measurement issue..need to understand the length and try again..
