Set Content Width

WordPress block themes include a layout setting that provides two essential key/value pairs for setting the content width:

• contentSize, which establishes the default width for blocks in both the editor and the front end
• wideSize, which activates the wide-width feature and sets the width for wider blocks

In Frost, the values for these are 640px and 1200px, respectively. These widths can be set using two different methods: via theme.json (Code) and through the Site Editor (No-code).

Setting Content Width (CODE)

Inside the theme.json file inside of the Frost theme, look for the code below. Change the values for Content and Wide as desired.

{
	"settings": {
		"layout": {
			"contentSize": "640px",
			"wideSize": "1200px"
		}
	}
}

Setting Content Width (NO-CODE)

Go to Appearance > Editor > Styles > Layout, and you will see a panel like the one below. Change the values for Content and Wide as desired.
