## Golden Ratio Clear Card that can be utilized for design and layout
The golden ratio is a rule based on the number "1 : 1.618", and is a ratio commonly seen in architecture, art, design that people find beautiful, as well as in many plants and organisms in the natural world. By knowing this golden ratio, you can add concrete clues to layout judgments that previously relied on intuition.
The 'Clear Card to Understand the Golden Ratio Instantly' is a clear card printed with lines of the golden spiral and the rule of thirds based on the golden ratio.
The red lines indicate the golden spiral, and the blue lines indicate the rule of thirds based on the golden ratio.
* For the rule of thirds, there are methods using diagonals, dividing all widths equally into three, and overlapping the golden ratio inside to divide into three. Our clear card adopts the rule of thirds using diagonals.
Because it uses clear material, you can proceed with your work while directly checking the ratio by overlaying it on your manuscript or rough sketch.
Since the lines can also be seen from the back, you can use it by reversing the front and back to match the motif you want to measure.
