You always read the old rule ?use serif type which is easier to read than sans serif.?
That may be true in print but it?s not online.
Reason: the lower resolution of the screen vs. print renders the serif imperfectly, making it less attractive and more difficult than sans serif to read.
With that in mind, here are the best typefaces for online marketing:
>> For e-mail marketing messages, use either 12-point Arial or Verdana.
>> Do not use Times Roman for web pages ? it?s a serif type and difficult to read online.
>> Recommended typefaces for web sites include Helvetica, Arial, Verdana, and other popular san serif fonts.
>> If your web pages are too light to read on screen or when printed, use a boldface font like Helvetica Bold Condensed.
>> The most common error in web page design is using too small a type size. Use at least 12-point type. Even 16-point won?t look awkward, and larger is easier to read than smaller.
>> For web page headlines, use Impact or Arial Bold in 2 or more point sizes larger than the body copy.
>> Avoid gray or colors other than black for headlines, except if you want to emphasize a word or short phrase within the headline, put it in red.
>> Georgia is a good font for subheads. Bold Times Roman can work for copy subheads in a pinch. As can bold Arial.
