After writing a couple of lines, if you think your font size is not good, then you can easily adjust it from the block setting situated on the right side. 

At first, click on the text block of which you want to alter the size. Then from the right sidebar, click on Typography and choose your preset size. There are some preset sizes available, choose one that you prefer. 

If none of the preset font sizes fulfills your need, then click on ‘custom’ and give your preferred size. 

Change Font Size in The Classic Editor

In the classic editor, you will be able to convert the selected text into any sized heading. But to do it, you need a free plugin called TinyMCE Advanced.

Install & activate the plugin, then open your post or create a new one. Now highlight the text that you want to alter the font size. After highlighting, choose the font size.

Change Font Size Using CSS

If you need to alter font size every time, then its easier to change the font size permanently from your theme.

To do this, navigate to Appearance -> Customize. This will open the theme customizer option. Click on ‘Additional CSS.’

In the left sidebar, you will see a text field, write your CSS code for changing the font size here. 

For example, if you want to change the size of the paragraph to 20px, write down the following code.

p { 

You will see the changes in the right-hand side of the screen. Similarly, you can change the heading size. If you want to change the heading size to 30px, write down the following code. 

h2 { 

In this way, you can change the size as much as you want.
