Using type well increases the amount of content read on your site. Type is all about detail.
First, select a typefaces that works well on screen. You shouldn’t need more than two or three. Ensure the smallest font used is legible.
Even when deciding something as minor as how to align text, there are design principles that will improve readability. Once known, you can follow these, with rigid consistency!
Fully Justified is Tidy… but Unreadable
This is where lines of text line up on both left and right.
For body copy: word spacing can vary so much, that ‘rivers’ of whitespace appear between the text. This is very distracting. In addition, those with dyslexia will hate you for it.
For headlines: vary font size from line to line. Often used on TV headlines, it looks tidy but again… very awkward to read.
In Most Cases, Left Works Best
Left aligned paragraphs deliver a straight left edge.
This anchors readers, so they know where the next line will start each time. This means paragraphs are read faster, increasing the number of articles that are likely to be read.
