The Golden Ratio: 1.000000 to 1.618034
or 0.618034 to 1.000000

This Fibonacci Gauge holds constant the "Golden Ratio" and takes the math out of creating pleasingly proportioned Art and Craft items. I make each gauge individually, using apple wood, metal hardware, and Danish oil finish. Apple wood is a wonderful medium for this tool, because it is durable and flexible, and attractive, with smooth satin texture. With proper care, it will last for many years. And I maintain a margin of error of less-than-two-percent, which provides a very accurate rendering of the Golden Ratio across the span so you can use it with confidence.

The size is 7 inches (18 cm) long, 1/4 inch (0.6 cm) thick, and the total usable span ranges from 1 1/2 inches (3.8 cm) to about 12 inches (30 cm). A fibonacci gauge this size is suitable for use with small to medium-sized objects or paintings/drawings. Permanent make-up artists have used them to design eyebrows. It can also be used in scaled drawings, bearing in mind that the actual golden ratio is 1.000 to 1.618, or 0.618 to 1.000, for when you need to calculate the actual dimensions. Since these gauges are made with high grade wood, no two of them are alike; each has a unique appearance or a "personality" all its own.

I can make larger fibonacci gauges if requested... usable on larger projects or drawings, or for demonstrating the golden ratio on a chalkboard. If you want a larger size, just ask. I have double-size fibonacci gauges made of cherry wood or walnut or mahogany wood in stock at a reasonable price (See my other listings). And if it does not render the golden ratio at at least 98 percent accuracy, it never leaves the shop.
