1. Changing the site-wide font size in your theme settings

If you are using a good WordPress theme to run your blog, then there will be almost certainly be an easy way to change the font size (site wide) in your theme settings.

First of all, you need to check and see if your WordPress theme offers you this option.

Move towards: Appearance β†’ Theme options

Once you’re there, look for menu options that clearly indicate the ability to control the visual style of your blog.

Words like “styling“and”typography”Are your best bet to look below. Here is where the font size settings can be changed in my theme, OptimizePress:

Changing the font size right in your WordPress theme’s options is by far the best, safest, and most durable way to do it.

You can also adjust the size of any font used in your blog, from body text to each of your different headers.

Just make sure you are fully aware that your font size can have a huge impact on how easy your blog content is to read.

If your font size is too small, it might alienate some of your readers who have trouble making fonts smaller or who have visual impairments.

2. Using custom CSS to change font sizes

If you’ve tried to find a way to change the font size in your WordPress theme, but can’t get any results …

Contact your theme developer or consult their help documentation before resorting to using custom CSS to change font sizes (unless you have experience with CSS), as this is where it matters. become technical.

Go to your theme’s website or WordPress listing in their repertoire of themes so:

Scroll down the page until the message “View Support Forum“button. Click on it.

This is where you can browse questions that other theme users have submitted (and that the theme company has answered), or ask your own. Although you can probably expect a quicker response to a question asked directly on the topic company’s website.

Either way, there’s a good chance there is a buried setting to change your font sizes somewhere in your WordPress theme – and the right help article or explanation from the team. Your theme’s support might be just what you need. Take some time to dig.

Now if you again can’t find any help articles and your theme developer can’t help you either … my next tip is to upgrade to a better WordPress theme.

Here are some of the fastest (free) WordPress themes on the market that I highly recommend today:

If you’ve never worked with CSS before, then change WordPress theme still going to be a lot easier than changing the font size with CSS.

Now, if you’re ready to change your blog’s font size using CSS (next best solution if your theme doesn’t give the option), here’s how to do it.

Move towards: Appearance β†’ Personalize

Because I am not a professional developer myself, I prefer to add CSS rules to my blog via the “Additional CSS“In the zone”Personalize“From my appearance settings (rather than modifying the actual CSS file for my whole site).

Once you’re there, look for the menu item for “Additional CSSAnd click on it.

If there is custom CSS already added to your theme, you’ll see it here:

This is where you’ll enter your new CSS rules (to change the font sizes of specific elements on your site).

If you want to change the font size of all paragraph text <p> at 18px (for example), which is the tag used for your general body content when writing blog content, then you add this following CSS rule:

p {
	font-size: 18px;

You can exchange the 18px whatever font size you want for your paragraph text – and you’re ready to go!

Before starting the publication: Make sure to preview the font size change in the preview area to the right of where you just added in the CSS rule, to make sure you get the result you want.

Finally, you are ready to publish and set the font size change live πŸ‘

3. Installation of a WordPress font plugin (like TinyMCE)

The last way you can change font size on your WordPress blog, is to use a plugin specially designed for this purpose.

The best (free) plugin on the market to accomplish this today is TinyMCE, and they make it easy to adjust the font size as you move around an individual post or page during the editing / writing process.

Here is a screenshot of all the new editing options that are added to your content editor once TinyMCE is installed, including the ability to change the font size:

The only reason that changing the font size with a WordPress plugin like TinyMCE is last on this list of options is because these types of plugins tend to add more bloat to your website.

This increases the amount of code that loads on each page and therefore takes longer to load (which is not an ideal blog SEO best practice).

In general, the faster you can load your blog pages, the more your site will be searched for by search engines – and therefore the more traffic you will get to your blog.

Along with the code bloat issue, TinyMCE can also be a bit overwhelming for new bloggers who don’t have a lot of behind-the-scenes experience with WordPress. It adds lots of new options and features and can drastically change the visual presentation of your content editor.

Final Verdict: What’s the best way to change the font size in WordPress?

Without question, the safest and most durable way to change the font size on your WordPress blog is to adjust it in your theme settings.

If your WordPress theme doesn’t offer an option to change the font size in its available settings, I highly recommend getting a new theme. Here are over 25 to consider. Believe me, if your existing theme doesn’t have this option, what else could be missing?

Finally, you can consider adding a new CSS rule that defines new font sizes for paragraph text or specific headings.

But if that’s too technical for you, go for a WordPress plugin like TinyMCE which will add font size options to your content editor.

Remember though, getting a more robust WordPress theme will always be your best bet if what you’re currently using doesn’t support changing the font size.
