Font types should be carefully selected. For standard text use fonts that
are legible (Arial, New Times Roman, etc.). For each lesson use three or
fewer fonts. Use one font for headings and titles and another for text
messages. Versatility can be achieved by varying the amount of size
rather than choosing a new font. Some fonts are better for headlines - they
are called sans serif fonts like Arial. Other fonts are better for body text.
They are called serif fonts like New Times Roman. Ensure font and size
selections are appropriate for on-screen reading.
San serif fonts are good for headlines.
Serif fonts (Times New Roman) are good for body text. They are easier
to read because the curly flourishes on the letters lead the reader's eye
along through the text.
The style of a font can contribute a certain message of its own (bold,
larger, italics, etc.). Use style to convey a message only when needed.
