Hi Jack,

To increase the paragraph and title size just login to your dashboard and go to Appearance > Customize > Additional CSS and paste the below custom CSS code:

body, input, textarea, select {
	font-size: 15px;
}
.entry-title {
	font-size: 28px;
}

Note: Increase the above digit value 15 for paragraph and 28 for title

Thank you!
