Best think to do it to change it in the css file.
Here’s how:
1) Log in, then go to Appearance > Editor
2) The style.css file should be the one you’re looking at, if not click it in list on the right hand side. This (put simply) is the file that controls the look of your site, ie general colours, font sizing and styles etc. Warning: You can mess up your site if you screw this up – a backup first is recommended!
3) In the editing page, search for body. It’ll look something like this:
body{
font-family:"Times New Roman",Georgia,Serif;
}
4) Change the font line to the font you like.
Things to note:
– The reason there are a few fonts written on this line is incase the first choice font isn’t available.
font-family: first choice, second choice, third choice;
– If your chosen font is more than one word, put ” ” around it,
ie: “Times New Roman”
The final serif/sans-serif at the end is in case none of your chosen fonts are on the users computer, and so the browser knows whether to choose a serif or sans-serif type font.
Hope this helps! Here’s some more reading on it, which may explain it better than I just did! CSS font-family Property
