Interesting statistics sort of related to learning
APRIL 15, 2009
For years, I abided by the rule that users (aka learners in my setting) liked reading text that was formatted into lines of about 4 inches in length. Turns out a really long line length of 10 inches may be better than the 4 inches I thought was best. People’s eyes have to switch back to the next line less often if the lenght is longer, which decreases the number of momentary losses of concentration as their eyes go from the end of one line to the start of the next.
