Hi, thanks for looking in. Typographically speaking, does size really matter? Personally, I don't believe it does! In this tutorial I will attempt to explain why.

There are a number of things that need to be taken into consideration when creating your website: Layout, Legibility, Ease of Navigation, but one of the most important of them all is choice of fonts, Choosing the right fonts goes a long way into determining how long visitors stay on your site.

So, how do you choose the right fonts? First they must be legible, easy on the eye, and appropriate to your niche. There are many fonts that appear very similar in style, but differ in one very important aspect:

What is x-height you may ask? It is the height from the baseline to the top of the lowercase letters and determines how large your text appears on your website. Even though fonts may have the same point or pixel size they can look quite different in size according to their x-height.

Now the question arises: Why use a font with a small x-height that needs to be increased to 19px (14pt, 1.2em); or 22px (16pt, 1.4em), to make it easily readable when you can use a similar font with a large x-height that is easily readable at 16px (12pt, 1em)?

As you can see from the previous paragraph, there are various ways to determine font size, but for this tutorial we'll keep it simple and use pixels. I would also advise using a test site and installing a simple custom css plugin, as this will save you the trouble of creating a child theme for a test site.

If the changes you make are successful, you can then create a child theme of your new or published website's parent stylesheet or you can carry on using a custom css plugin, just install it into your published website and copy and paste the changes from your test site into the plugin or your newly created child theme.

In the following pages I will be giving examples of fonts similar in appearance but with different x-heights, character widths, line-heights, letter spacing, etc. These can all be modified in your child theme or css plugin, which I will be explaining as we progress. The fonts I have used are purely for demonstration purposes and need not be used on your website unless you so wish.

These can also be modified by using HTML code, but isn't recommended unless it is just for the odd paragraph, heading, or horizontal rule, as you would need to do it for each paragraph, heading, and horizontal rule, creating problems with loading time and inline css.

It would also create problems if you want to edit your pages and posts, as each page would have to be edited individually, one hell of a task if you have a large number of posts and pages. Using css will automatically apply any changes you make to all your posts and pages.
