**Universal design rules** may not always be the measure of all things, but they can help to achieve success in different areas, including communications, manufacturing, services, technology, art and environmental design.

Only the product that is created using these rules gets the highest demand of the consumer. Main principles of these rules can be applied in *art, architecture, photography, interior design, communication technologies including advertising and website design*. Original purpose of design is the aesthetic appeal of the product. For competitive realization of design ideas one need to understand the processes that affect human perception.

**Design rules that will work for you:**

- Occam's Razor
- Fibonacci sequence
- The Golden Ratio
- The Rule of Thirds
- Pareto Law
- Signal-to-Noise ratio
- The Law of Perception

Occam's razor (the law of minimum assumptions) - formulated in the 14th century by Father of Church William of Ockham, the law which was ahead of its time. This law is not indisputable, scientific progress can do without it, but, however, it shows that the most appropriate solution is the simplest one. In other words, the most preferable is the simplest explanation of theory that becomes the only correct explanation/solution.

Leonardo da Vinci pointed out: **"Simplicity - is the most ultimate sophistication."** When applied to design, Occam's Razor warns that unnecessary complexity should be avoided in presentation of information.

*To understand this law better here are examples from TemplateMonster's collection:*

The Fibonacci sequence is named after Leonardo of Pisa, who was also known as Fibonacci. The sequence was revived in early 13th century, but was seen previously in works of old Indian mathematicians. The sequence continues by summing the last two numbers. It starts with **0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, etc**.

**Interesting!** *This sequence can be seen in nature (branching of the tree, the petals and leaves of most plants, as well as in the behavior of the bees).*

Most people find such designs as the most aesthetic ones. In fact, many of us consider this sequence as the most important model in mathematics, as well as in web design. It can be successfully used to create drawings and geometric and organic ornaments, and visual images, and even for individual tracks.

If you look at the Fibonacci sequence and consider them as possible section, margin and font sizing it should be clear that it can structure your entire design. The smaller range of the sequence **(8, 13, 21, 34, 55)** is perfect to decide margins, line heights and font sizes. The higher range of the sequence **(144, 233, 377, 610, 987)** can easily decide column widths and other section dimensions.

The Golden Ratio - in fact, this is mathematical variation of the Fibonacci sequence. Golden ratio - is a constant equal to **1.6180339887**. This law was realized more than 2,000 years ago, but for the first time Euclid defined it. Golden ratio justifies the choice of proportions of shapes of the design so that it will look more attractive.

"Geometry has two treasures: one of them - the theorem of Pythagoras, and the other - division of lines of the golden ratio. First is the precious metal of geometry, and the second is it's jewel"- Johannes Kepler.

The idea of the golden ratio is following: a larger part of one segment is referred to its lesser part as the whole segment refers to its greater part. This ratio describes the relationship between the long and short sides of the rectangle...

*Here are the examples of practical application of Golden Ratio into TemplateMonster's templates:*

**The rule of thirds** may resemble the golden section, but, in fact, it's not the same thing. This law has been ascertained for the first time in 1797 in the book of John Thomas Smith, "Notes on the background of the rural landscape." Smith saw his discovery as a generalized rule, not as an absolute law. However, in reality it turns out that if designers do not neglect this law, the results would be the most attractive for most users.

If we divide any image by imaginary horizontal and vertical squares into nine blocks, the line and the intersection of the lines will be the most important. The division of space on the image divided in to two parts onlу of them is the sky and the other one is the earth, or the sky and the water on one of the three horizontal lines is also preferable to division into two similar parts. Such disproportionate division concentrates energy and attracts more interest. For artists and designers the understanding of the rule of thirds can lead to an increase in audience interest towards their works.

*This is how this rule works in TemplateMonster's themes:*

The essence of the **Pareto law** or the **80/20 rule** is well known to team leaders, those who run meetings. Pareto's law states that no matter how many events occurred, 20% of the results are caused by 80% of the efforts.

Joseph M. Juran in 1906, called this phenomenon after Wilfredo Pareto, who proved that 80% of land in Italy belongs to 20% of population of Italy. This law was explaining why 20% of criminals commit 80% of all crimes, and why 20% of all users of the health system use 80% of its services. And in general, why 80% of all results come from 20% of all actions.

For practical use in the website, the statement should be the following: if 80% of users use only 20% of the information provided, columns, buttons, etc., than everything that is not in use should be reduced or replaced with something more efficient (or even avoided). This solution is supported by Occam's Razor - an irrational approach to simplicity of use.

Signal-to-Noise ratio determines the true balance between **message and background noise**, which may limit or reduce the value of the message. If the proposed ratio is **1:1**, it means that the background noise is almost equal to the power of posts. In this case, the results will be lower than expected.

Correction may be in the selection of the main element, which can be both audible and visual. This may also include the removal and reduction or distracting sounds or visual disturbances.

If you let important and useful information to take the main place and reduce unnecessary and useless information, it will definitely bring good results.

The law of perception practically speaks for itself. If the information or instructions are not presented in an accessible form, this information will be ineffective, and it will not have a positive effect. In most cases, the best guidance is the shortest and the simplest. Equal use of audio and video formats, including graphics and text, may make guidance more informative and at the same time easy-to-read.

Using a variety of following elements will work for you, they include: important instructions, directions and information keys.

**Сonclusio**

You may want to consider other principles and laws, such as *equal use of nearby objects* and *the law of physical force*, etc. There are many cases in which these laws can have an important role, as part of the design process. *If you find theme theme really interesting and useful feel free to express you opinion in the comments section and we will consider posting the continuation of this article.*

Understanding that "there is one common consciousness of each individual" (R. Emerson) means that the better you understand human nature and what drives our perception, the better your design will be.

**In a few words:** all spheres of human activity are interconnected, if we make an intense brainstorming we will find links with some absolutely unexpected things like the influence of Large Hadron Collider on web design, or how movement of subatomic particles affects image sliders.

**P.S.** *If you know other rules aimed at making designs better spread the word in the comments section.*
