Hi,

1. First check the documentation that it has any option to customize the fonts in Appearance -> Customize.
2. If not, add this in CSS snippet in your child theme’s style.css last line, or add this in any Custom CSS plugin,

.page-title, .entry-title {
    font-size: 1.5em;
}

Instead of 1.5em, you can use px too, like 20px like that.

Regards,
