Golden Ratio Calculator++
Make your layouts divine
Golden Ratio Calculator++ calculates the width or height of a rectangle using the golden ratio, the silver ratio or any other ratio of your choice. You have the length of one side, Golden Ratio Calculator++ finds the other. Golden Ratio Calculator++ is the best and fastest way to easily incorporate the golden ratio in your layouts or designs!

I build my own canvases and like to use the four ratios preset in this app. This app also gives calculations for any other random ratio by using the slider while also giving an immediate visual of the shape proportions. Multiple decimals are available in settings. All functions are quick and easy. This is the perfect app!

Beloved by users, Golden Ratio Calculator++ will make your creative life easier:
The Golden Ratio is just as useful as Pi. Your calculator is just what I was looking for. I could do the same thing with a Calculator or a Slip Stick but your App is SO much faster. THANK YOU!

The calculated value is automatically added the pasteboard, making it easy to use it in other apps. You can also adjust the accuracy of calculation, making the results suited to your needs.

Golden Ratio Calculator++ comes preloaded with a host of useful ratios, all of them also available as quick actions or from Spotlight:
The golden ratio is a special number approximately equal to 1.618. It appears many times in geometry, art, architecture and other areas, often with pleasing results. It has been called divine proportion due to its numerous occurrences in nature.
The silver ratio arises in many mathematical and geometric expressions. The name is an allusion to the golden ratio; analogously to the way the golden ratio is the limiting ratio of consecutive Fibonacci numbers, the silver ratio is the limiting ratio of consecutive Pell numbers. You can cut A-series paper in half repeatedly and maintain the silver ratio.
The bronze ratio is often used in origami for making shapes with 30°, 60° or 120° angles.
The Yamato ratio is the ratio used for the face of a Buddha statue, Japanese architecture, sculptures and flower arrangements.
All these ratios make the app incredibly useful while doing design or layout work.
