Description

Font is defined as a design describing size, style, height and thickness for a groups of characters. E.g. a group of characters for Times New Roman for a certain size(lets say 10) is a font. While doing the usability design it is important to ensure that due consideration is placed on the right usage of the fonts, in terms of their style, size, color, highlighting/underline patterns etc. A rightly used font to display text/information to the user can go a long way in providing higher usability index for the application.


Some usability guidelines

  • Unless required, try to use the fonts which are already defined by the system.
  • If you are using custom fonts that not defined in system then make sure that it will render properly on all devices

  • While defining the font size, the screen resolution must be kept in mind.
  • Keep the font size which is in sync with the display screen space available to the application.

  • Font should make text easily readable. Font properties like color/size/style should make the text look nice on the UI.
  • While using background images, use a proper combination of font type and colour so that the text is readable.
  • Keep the backgrounds behind your text solid and plain, it is more readable.
  • Because blue-receptors in the eye are least numerous, avoid blue for small font.
  • It serves to use the font in sync with the overall theme color/background image combinations to give it a harmonious look on the UI.
  • One can make use of bold font styles or use underlines etc so that the text looks highlighted and easily noticable.

  • The best combination for readability is black font on a white background and vice versa.
