Footer Widgets

You can use up to five footer widget areas and can choose whether to display zero – five of them at any time.

Global Setting

You can find the global setting to set the number of footer widgets in Customize > Layout > Footer.

Change the number of footer widgets on individual pages/posts

Some individual pages and posts might require a different number of footer widgets than your global settings. In this case, you can use the Layout metabox while editing that page/post.
