Sourcing the fonts
I often start with Google Fonts, for their simplicity in using the fonts both online and offline, the handy preview features and the ability to download the fonts for use offline. Offline fonts help when producing the website and design mock-ups, as you can play around with a bunch of ideas and test out sizes and typography layout options, to see how they look in situ with the rest of your design ideas. You can also set up layouts for all your responsive screen sizes, to test the fonts at all the necessary scales to make sure they’ll look great everywhere.
There are a lot of alternative options like Adobe TypeKit, or simply using a site similar to dafont or purchasing typefaces on sites like MyFonts.
A lot of these font services will provide something similar to Google fonts although I don’t feel that they’re as easy to implement. I guess it’s down to the fact that Google fonts are free for everyone and are incorporated into a lot of WordPress templates and other similar systems already. Whereas to access some services like Adobe fonts, you need to purchase them or have a Creative Cloud subscription.
While tinkering with my rebrand, I’ve considered a wide range of fonts, as you can see from the image shown here. I like to get an idea of how they look using specific phrases and lettering so I can be sure they will work for my needs. Quite often a font (especially the more fancy styles) will be designed to look amazing using particular letter combinations *usually the name chosen for the font. But when you attempt to use them for more practical purposes, they can fail as the letter combinations do not join or link up well. More modern fonts include different ligatures for individual letters so you can choose a character style that works with your copy, but web-fonts still have a way to go to catch up.
I usually find a font (or at least typestyle) I like the look of and use it to create some design mock-ups. These can be anything from web page layouts to a business card or stationery layouts or a couple of poster designs. It is vital to ensure that the chosen font will work across all your marketing and media, so trying it out in multiple environments and sizes is an excellent way to test its mettle.
