Hello,

To restrict the number of words on a page is not an available feature.

But, to restrict the number of words in a post is possible if you edit an individual post(edited) then you can find an ‘Excerpt’in the right side which appears like the screenshot below:

And after the post displays, the front page looks like the screenshot below. You can add the text you want to display.

Hope this helps.

If you have further queries, let us know.

Thank you.

Hello,

The feature to limit word through the Excerpt option is a feature given by WordPress itself. No plugin is required for the excerpt option to appear in the post editor.

However, to limit word on the page, you can add the given code in the child theme. Firstly, you have to create a child theme referring to the documentation below:

https://wptravel.io/how-to-create-a-child-theme/

Then you can add the code given below in the function.php folder of the child theme

add_action( 'init', 'add_excerpts_to_pages' );
function add_excerpts_to_pages() {
    add_post_type_support( 'page', 'excerpt' );
}

Hope this helps.

If you have further queries, let us know.

Thank you.
