Hi vf478,
The length of the text is displayed from the excerpt. You need to change in the core file. We always recommended you to change create a child theme before making any changes on it.
The core file is inside interface -> inc -> functions -> functions.php on line no 146 and change the numeric value to any value you want.

function interface_excerpt_length( $length ) {
	return 50;  // this will return 50 words in the excerpt
}

Thank you!
