The theory is that serif fonts are easier to read than sans-serifs. Almost all
commercially printed material in the UK (books and newspapers) are in serifs
such as a Times Roman or a Garamond. Wikipedia says that the use of
sans-serif fonts are more common in Europe than the US.
Personally I favour fonts that are in the humanist sans-serif family, such as
Gill Sans. Though I usually end up using Verdana which is only a
semi-humanist sans-serif, but because it was designed for low resolution
computer screen use it is easy to read. Apparently Tahoma and Vera
Sans/DejaVu Sans are reasonable Verdana substitutes.
