Serif fonts are those which have small thin extensions at the ends of the lines in letters.

Serifs make sentences more readable.

T

San-serif fonts have clear lines, not at all fancy.

Text Style

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.
