Many designers fail because they don't know how to use text correctly. Visual messages must be accompanied by the proper use of typography to be truly effective. Therefore, it is important to take into account the following 18 rules:
Know the font's personality: Every typeface has a personality that works or doesn't work depending on the context. It's important to be very clear about the audience and purpose of the design to avoid ruining the work.
Avoid default fonts: It gives a bad impression to use default fonts in Word or InDesign, it indicates that the designer does not know that other fonts exist. While Time New Roman and Calibri are not bad fonts, they have been used too much.
Stay away from clichés: Some fonts have become french mobile numbers very popular because they are installed by default, so it is essential to avoid using them. Also, installing a new font on a computer is very simple.
Use two fonts: Most designs look better when more than one font is used. However, more than three fonts is a mistake unless you are designing a collage. It is always a good idea to use one font for headings and another for the actual text.
Use contrasting fonts: While it is good to use two typefaces, it is important to use two fonts that do not look alike. That is, they are not part of the same family.
Pay attention to size: the default size of 12 points doesn't matter, it doesn't mean that everything has to be readable at that size. For example, it has been proven that most documents are perfectly legible using a 10-point font.
Avoid capital letters: when writing in capital letters, all shapes disappear and words become simple rectangles. Furthermore, using capital letters is synonymous with shouting.
Beware of inverse colours: using light text on dark text or vice versa is useful for titles and headings, but not for much else. If you use this resource, make sure to use high contrast colours.
Line length or underlining: If you underline too much, the text will become difficult to read. For example, lines should be long as long as the font size is large enough, as in a news headline.
Adjust line spacing: The vast majority of line spacing is designed to be slightly larger than the font size. However, a recommended technique is to increase line spacing to improve readability when dealing with large text boxes.
Readability: the idea is to find an optimal level of writing for the text, accessible to the target audience. Technical texts should be reserved for the specific target audience.
Legibility: All important content must be 100% legible, functionality is always above design. Sometimes difficult-to-read text can be very attractive if used correctly, such as in a logo .
Use of small caps: small caps have legibility problems if used in very large sections of text. Small caps should be used for abbreviations and never capital letters, in this way the user's attention would not be immediately drawn to the abbreviation.
Avoid line breaks: they are aesthetically terrible and very bad for reading.
Don't leave any orphans: It is best to reformulate the texts so that no words are left behind. Generally, this problem is solved by using justified paragraphs.
