1 Why You Should Change The Font In WordPress?

Typography can give any website a whole new appearance and feel. Everything from the font size to the color of the text could be a factor. It’s a means of indicating professionalism and is frequently used to engage a specific audience.

On a desktop computer, some WordPress layouts may look stunning while they may appear radically different when seen on a mobile device.

Your content’s structure is crucial for visitors and SEO. A decent content structure helps search engines scan the primary subjects of your content, particularly lengthy ones. This will assist in obtaining a higher ranking on search engine results pages.

There are various ways you can change the font size in WordPress. So, without further ado, let’s get started.

2 How to Change The Font Size In WordPress

2.1 Using the Headings

You can choose to use the headings to change the font size in WordPress posts. Using headings in your content to attract user attention with a larger font is one of the best approaches. Headings usually appear in a larger font than typical body text in most WordPress themes. You can use them to divide your posts and pages into sections.

Headings are also beneficial to SEO. You should not forget that search engines give proper headings more weight than regular paragraph content.

You might be able to modify the font size in some WordPress themes. If you can identify it, you can use it without writing CSS code. However, if your theme doesn’t have that feature, you can use custom CSS to create your own font size rules.
