Presentation is crucial to all forms of communication. There are several factors to be considered while designing a website and selecting the appropriate font type constitute a major decision as whatever content is written must be easy on eyes and readable. The selected font for a website should accomplish the following:

1. Focus attention
2. Enhance readability
3. Establish a tone
4. Project an image

Guidelines:

• Use CSS to apply the corporate fonts through controlled style sheets
• Make the default font size reasonably big (at least 10 point equivalent)
• If your site is targeted to senior citizens users, use bigger default font sizes (at least 12 point equivalent).
• If possible, avoid text that is embedded within a graphic, style sheets and font size buttons do not have any effect on graphics
• Have font size adjuster prominent on the website
• Set your font sizes using relative measurements or avoid setting font sizes altogether.
Relative or flexible units can be chosen from:

1. Percentages (%) increase or decrease from the browser font size set
2. Em (relative to the size of the capital M)
3. Ex (relative to the size of the capital X)
4. Keywords (small, medium, larger, smaller, etc.)
5. Signed units (+1, -2, etc) (HTML only)

• Avoid font sizing based on absolute or fixed units such as points (pt) , pixels(px), centimeters(cm), millimeters(mm) and inches(in).Instead, use % and “em”
• In sites where it is necessary for users to read a lot of information, use lower-case fonts and appropriate capitalization to ensure the fastest possible reading speed
• Use bold text only when it is important to draw the user’s attention to a specific piece of information

Validation Techniques:

Change the browser text size settings to "largest" and "smallest" to ensure that all text is still legible
