Many of the core principles of design are based in maths to determine the scale and layout that can be beneficial to use within designs. 2 of these core principles are the:

• Fibonacci sequence - the Fibonacci sequence can be used to determine the scale that is used within many different elements within any design, the sequence ( 1, 1, 2, 3, 5, 8, etc.) can often be used to calculate the sizes of different elements within your design I.e. the width or height of an image being used in a design.
• Golden ratio - the golden ratio can effectively used to guide the layout of a design and the positions of different elements in a design, by using this to guide the layout it can also help to determine the sizes of different elements within a design like text, images and graphics.

By using maths to determine and guide choices for a design it helps to ensure consistency within a design, it also allows designers to effectively use hierarchy within their designs. By having designs be consistent it will make them more visually appealing and audiences will want to engage with that design.

Dieter Rams 10 principles of good design

• Dieter Rams: 10 Timeless Commandments for Good Design | IxDF

These 10 principles say that good designs are:

1. Innovative - Designs should adapt and advance as technologies advance as these designs will need to keep up with and be usable on these new technologies.
2. Makes a product useful - Any design should be able to effectively be used to complete its main function, it should be fully functional and allow the user to use the product for what it is designed for.
3. Aesthetic - All designs should be nice to look at and use, if a design looks nice the user will be more likely to want to use the product.
4. Makes a product understandable - A good design should be easy to understand and use, designs should be intuitive and allow for users to easily discover and know how a design funcitons.
5. Unobtrusive
6. Honest
7. Long-lasting
8. Thorough down to the last detail
9. Environmentally friendly
10. Involves as little design as possible - Good designs should show the most important aspects clearly, to achieve this designs should not be overly busy or complicated.
