What it is
Fonts Knowledge is a free learning section of Google Fonts. It is organised into modules, including Introducing type, Choosing type and Using type, made of short, illustrated articles. It explains the vocabulary of typography and, more usefully, the decisions behind it: which typeface suits a purpose, how to pair two, and how size, weight, spacing and line length change readability.
Why it matters for AI creative work
Text is where AI visuals most often go wrong, and where clients notice first. Even when a generator spells words correctly, the result may be the wrong weight, poorly spaced or unreadable at thumbnail size. Most professionals add final text in an editor such as Canva, Photoshop, Figma or a video editor, and that means making typography decisions yourself:
- picking a typeface that matches the brand's personality
- pairing at most two typefaces, one for headlines and one for supporting text
- choosing a weight and size that read in a second on a phone
- setting leading (space between lines) and kerning (space between letters)
- keeping enough contrast with the background
How to learn from it
- Read one module at a time, then open an ad or thumbnail you made and fix its type using what you learned.
- Collect five ads you think have great type and note the typefaces, weights and spacing.
- Build a small type scale for one brand: headline, subhead, body and caption sizes, and reuse it everywhere.
- For captions in video, test readability on a phone at arm's length, in daylight.
Licensing note
Fonts on Google Fonts are open source and can generally be used in commercial projects, which makes them a safe default for client work. Always check the licence of any font from elsewhere before using it in a client's ad.
Who it suits
Anyone who puts words on images or video, especially beginners whose designs look amateur without knowing why.
