The Six Principles of Design

1. Balance

2. Proximity

3. Alignment

4. Repetition/Consistency

5. Contrast

6. White Space  

Balance:

there is writing on both sides of the page, the weight of the writing is distributed evenly on the page. an example would be writing on both sides of the paper, a non example would be writing on only one side of the paper.

Proximity

the distance between two elements on a page, an example would be putting a caption next to the related photograph, a non example would be putting a caption far away from the related photograph or not putting a caption at all.

Alignment:

the justification of elements, emphasize their relationship to each other. an example would be centering the location, date, time and the cost of an event on a flyer

Repetition/Consistency:

Consistent pattern of font and color schemes and graphic types. an example would be a specific font size, and color for headings, sub headings and body text.

Contrast

using colors to emphasize the importance of the text on a page. an example would be using black or dark font on a light colored page.

White Space:

Blank or unused space on a page, it's used to focus the reader's attention on important details. an example of white space would be using a wide margin.
