Case & Spacing
  • Use proportional spacing - Proportional spacing is more legible and facilitates word recognition. Monospacing is appropriate when an aligned structure is needed such as in tables of numbers. Monospacing can also be used in single line input fields for clarity.
  • Upper and lower case - UPPERCASE IS MORE DIFFICULT TO READ than lowercase. Lowercase letters are more distinct from each other which aids the perception of words by shape. Uppercase should be reserved for titles, captions, or labels that need to standout.
    • Mixed Case - increases reading ease.
    • Uppercase - decreases search time when embedded in mixed or lower case.
  • Italics - Avoid the use of italics on electonic displays. They are typically difficult to read, particularly for longer text passages displayed. One reason, is that displays do not render slanted lines well. As opposed to vertical lines, slanted lines appear wavy.
