Typography is the art and technique of arranging and formatting text. Type is not just used for body text, headings and captions but can also be used to create bespoke logos and branding with or without the additional use of graphics. A typeface is made up of consistently designed glyphs which are singularly formed characters usually representing a letter, numeric digit or punctuation symbol. Studying and extracting the shapes and idiosyncracies of individual characters within a font can produce original and impactive results.
Choosing and displaying the fonts that best suit your project is an important part of the design process for many reasons and cross-platform compatibility, type size and legibility may need to be considered as well as being able to use your chosen typeface across a wide range of media platforms to give a consistent branding identity.
