The choice of fonts is very important for any print or web project. Like colours, the typeface can determine the mood and feel of a design as well as readability and style.
So here are some basics:
Letterforms and fonts vary in where the x-height falls, and how long ascenders and descenders are. These factors shape the style and effect fonts and letterforms have. These factors also affect readability of the text.
Typographical faces are split into two main groups. Sans Serif and Serif. Serif faces are those which have short strokes which project from the principal strokes of the character, otherwise known as “feet”.
Leading, Kerning and Tracking
Leading is pronounced "ledding," as in lead, the metal. Because in the days of mechanical typesetting they used strips of lead to create space between lines of text. In other words, leading is line spacing. With it, the designer can alter the density of blocks of text. Newspapers are quite dense and as such use a tighter line spacing value than you would find in magazines, brochures, or posters.When the typeface is designed, the designer assigns a particular amount of space for each character. Sometimes it is not enough and sometimes it is too much. Tracking allows you to manually adjust the space between all the characters evenly.
Kerning allows you to manually adjust the space between any two characters.
When using letterforms consider all these elements, and choose a typeface that is appropriate for your design. Usually, it is better to use only one, maybe two different fonts in each design, more than that is just unnecessary and will make the design look messy.
