Here's some more wisdom from Helen Hollick about choosing the correct font for your book.
My UK books published by SilverWood Books are set in Palatino, which is a nice rounded serif font created in the 20th century. Very readable!
Helen Hart says: "Most book publishers will have a pallette of tried and trusted fonts which are selected for their readability. Among them will be Palatino, Sabon, Garamond, Baskerville and Swift. These fonts have one thing in common - they're simple, effective and lead the reading eye over the words so that the content can be easily absorbed by the reader."
So what are the Fonts?
Serif fonts have a little line at the end of each stroke. Some examples are:
Serif fonts can be used for every part of your book. such as title, chapter titles, main text, contents table - everything. It is easy to read large blocks of Serif fonts printed text, and should be the only type of font used for the main body text of your book. Except for Times New Roman, which was designed for newspaper printing presses in the 1930’s 1932 and is not suitable for modern printed books. It can make your book appear unprofessional.
Non-serif fonts: There is no little line at the end of each stroke in non-serif fonts.
These are appropriate for the title, chapter headings, headers, footers, subheadings and short lines of text, such but they are not ideal for use as the entire chapter of text or large blocks of text, such as an introduction because the font is not easily readable in a printed format
Text on the Computer Screen:
Note – reading text on a screen is very different to reading text in a printed book. If your text looks pretty good on screen in a sans-serif font, it’s readability could be very different when it appears in your printed novel (or submitted MS!)
Are for design and artwork - for the titles on the cover, and maybe sub titles Part One, etc. Be careful – what may look good on your computer can look terrible in your printed book.
Bold and Italics:
Need bold or italics added to your text? Make sure you use a true bold or italic font – i.e. that the font has a different font set as a normal, bold, and italic face. If it doesn’t have this capability a “fake” bold or italic will be applied and the quality of print in the final actual version could be corrupted.
So what is wrong with Comic Sans?
The word “comic” should tell you all you need to know.
It is a perfectly adequate design for children, comic books or cartoons, but it has no place in professional work. It is ill-suited for large amounts of text.
