Hi,

You see the font size on the posts titles is small because the font you're using for heading titles now ( "Rancho" font ) has smaller font size than other fonts.

I recommend you select another font has normal font size to get it better.

If you want to keep that font, you can try add more this code to Customize > Custom CSS to change font size for it:

.home-featured-cat-content .magcat-detail h3 a,
.widget ul.side-newsfeed li .side-item .side-item-text h4 a,
.post-pagination h5, .item-related h3 a, 
.penci-rlt-popup .rltpopup-meta .rltpopup-title{ font-size: 20px; }
.home-featured-cat-content .first-post .magcat-detail h3 a,
.penci-grid li .item h2 a, .penci-masonry .item-masonry h2 a{ font-size: 24px; }

Change values 20 and 24 to values as you want.
