What is theme.json?
theme.json is a special file used in WordPress block themes to control the design of your site, like colors, spacing, fonts, and more — all without touching CSS or PHP.
What is Typography (Font Family)?
Typography refers to how text looks on your website. A font family is just the name of a group of fonts, like "Arial, sans-serif" or "Roboto".
Where do you add fonts in theme.json?
You add fonts in this section:
"settings": {
"typography": {
"fontFamilies": [ ... ]
}
}
Each font entry looks like this:
{
"fontFamily": "Arial, sans-serif",
"slug": "arial-sans",
"name": "Arial"
}
- fontFamily: the actual font (like in CSS)
- slug: a unique ID used in the background
- name: what shows in the WordPress editor
