Case
Exclusive use of UPPER CASE letters is justified in the case of CAPTIONS or LABELS.
As a regular practice, AVOID USING CAPITALS UNNECESSARILY, it reduces readability.
Text Size (48)
• Use 24 - 30 point font size
• Less than 24 is too small
• Greater than 30 is overpowering
• Titles may be greater than 30.
