How to make WordPress Gutenberg editor wider in Genesis Sample theme

You probably noticed that content in WordPress editor becomes narrow – fills much less screen space than usual once you switch to Genesis Sample theme. It may not be a deal breaker, but it’s still not convenient if you’re using high resolution screen. Especially if you use multiple columns in pages or posts.

There are two ways to control how wide WordPress editor should in using Genesis Sample theme (or in most other themes built on Genesis framework):

I’ll show you both of them – feel free to use the one which fits your workflow best.

How to change WordPress editor width in Genesis themes

By default WordPress editor looks up for Gutenberg editor styling information in currently active theme’s files. Genesis Sample theme has some custom CSS for WordPress editor in it’s folders. So in order to change editor width we’ll need to edit one css file.

Go to Appearance >> Theme File Editor, and open lib >> gutenberg >> style-editor.css file in the editor.

To make default WordPress blocks wider you need to change .wp-block max-width to a larger number. For example, to 960px:

.wp-block {
   max-width: 960px;

You may also change wider or full width block maximum width:

.wp-block[data-align="full"] .wp-block[data-align="wide"],
.wp-block[data-align="wide"] .wp-block[data-align="wide"],
.wp-block[data-align="wide"] {
	max-width: 1200px;

After saving changes WordPress editor content will be wider – no need to make any extra steps.

In the same css file you may change font sizes, change font family, and other WordPress editor elements to make sure that WordPress editor looks similar as your customized Genesis Sample theme.
