Fonts are very personal things.
Whilst most people would agree that a font such as Comic Sans wouldn't be the best choice for a serious site, there's often heated discussion about the best font to use for websites.
Whilst the final choice is obviously yours, you should at least take into account some of these thoughts.
Serif or Sans Serif? Serif fonts have small extra parts that were originally designed to help our eyes read printed words and quickly understand what was printed.
Sans serif fonts don't have those optional extras.
Logically, if serif fonts are best on the printed page, that means that the same should apply to the web.
Unfortunately, logic doesn't necessarily work in this situation.
Because of the limited number of pixels available on computer and mobile screens, serif fonts aren't necessarily the best choice.
But you need to combine that information with the next point.
Fonts designed for the screen? Ideally, you should use fonts such as Verdana and Georgia that have been specially designed for viewing on screen.
There are subtle differences between how we see things on a screen versus how we see them when they are printed and these fonts are two of the earliest ones to be designed specifically for being read on screen.
Naturally, if your company has an official font that it uses then you will need to consult with higher powers to find out whether you have to use the company font or whether you're allowed to use one that works better on screen.
You also need to remember that not every computer has the same fonts installed, which brings us on to the next point.
Specify alternatives? Until recently, it was essential to specify alternative fonts using various commands in your site's CSS file.
The logic behind this is that not all systems have the same fonts installed.
There are very few fonts that are available on Windows, Mac and Linux machines.
Let alone all the various mobile devices that are increasingly being used for web browsing.
This means that your web designer needs to supply a list of alternatives in the CSS file for your website.
These are listed in descending order of preference, so the first font listed will be used if it is present on the users machine, then the next font and so on.
If you don't take this basic step then your pages are at the mercy of what the browser decides to use.
Another option nowadays is to use embedded fonts in much the same way that PDFs contain the necessary information without you having to actually install the font on the device you're reading them from.
This can be a good option but you need to remember that there will be an additional overhead whilst the user's device downloads the necessary information so you need to check that choosing this option doesn't impair your site's loading speed too much.
As with almost everything, there's no perfect solution to choosing a font for your website.
There are also other considerations such as colour schemes and font sizes that you need to consider as well but at least you should now have a clearer idea about the fonts themselves and what works best for your website.
