Typography. This is the term for all the text in your design, the fonts and sizes used, and how they show up on your site. You should use a consistent hierarchy throughout all pages when applying size, weight and strength of your header, sub-header and body text.
The size of your text should be balanced and consistent. That means use the same font throughout your site for your body text, and the same font for all of your headers.
There are so many fonts to choose from and it can be tempting to try to use all your favourites, but, limit yourself here! Choose one font for headers and one more for body. Maybe if you’re feeling really creative, choose one more additional display font. And make sure your chosen fonts play well together! Don’t pair two serif fonts together, or two really boring fonts. Again, you’re looking for balance here. There can be a bit of an art to this. Working with a good designer can help here, because they’ll do this automatically and you won’t have to think about it, but you can totally do this yourself too.
Bonus Tip: Here’s a good cheat sheet for how to pair fonts together!
Keeping it simple with typography ensures that your site visitors are not being distracted by how your words look, but they’re actually reading and connecting with your thoughtfully planned out message!
This goes without saying, but please use very readable fonts and text sizes! Same as above, don’t distract your customers with funky things that are hard to read.
