Elegant calipers empowering you to discover the golden ratio around you and to use this tool to aid in designing your creations.

Due to its precise design, the middle pointer always proportionally indicates the golden ratio with respect to the width of the outer arms.

The Proportioner's range is from 1-5/8" to 1'2-3/4" (41-375mm).

The whole is to the larger segment in exactly the same "golden ratio" as the larger segment is to the smaller. The golden ratio (~1.618), symbolized by the Greek letter Phi (Φ), is a gateway to the study of sacred geometry.

The golden ratio is found in mathematics, geometry, music, philosophy, psychology, art, archaeology, architecture, geography, molecular biology, plant morphology, human physiology, physics and astronomy.

The golden ratio isn't some rarefied or esoteric thing. It's used extensively in corporate logos and chances are you have several golden rectangles on you right now in the form of credit cards.

People consistently prefer designs with golden ratios without necessarily being aware of its presence or even its existence. The best designers know this proportion really works! Why not incorporate its natural power into your own designs?

If mechanical hinges loosen over time, you can easily finger-tighten their wide slotted heads. The Proportioner comes pre-assembled and are ready to use, right out of the box.

Warning: Keep Proportioners away from small children. Proportioners are not toys. Proportioners have pointy ends and thin parts that can be broken if sat on or otherwise misused.

Proportioners make thoughtful gifts for the artists, scientists, intellectuals, and would-be philosophers in your life. I hope you will acquire one or a trio today and bring the golden ratio into your life and/or the lives of your loved ones!

I love this caliper so much. The legs move smoothly and it's made of a high quality material. Such a nice addition to my collection of math and physics-related objects. It also arrived surprisingly fast from Canada. Thank you very much, Scott :)

Love, love, love! The calipers have just the right amount of resistance to move them comfortably and maintain their set position. They're lightweight and decently sturdy. Highly recommend!
