You Read Faster With a longer Line Length But Prefer Shorter

One of the psychology experiment says that “You Read Faster With a longer Line Length But Prefer Shorter”

Have you ever had to decide how wide a column of text you should use on a screen? Should you use a wide column with 100 characters per line? or a short column with 50 characters per line?

It turns out that the answer depends on whether you want people to read faster or whether you want them to like the page!

Research demonstrates that 100 characters per line is the optimal length for on-screen reading speed; but it’s not what people prefer. People read faster with longer line lengths (100 characters per line), but they prefer a short or medium line length (45 to 72 characters per line). In the example above from the New York Times Reader, the line length averages 39 characters per line.

The research also shows that people can read one single wide column faster than multiple columns, but they prefer multiple columns (like the New York Times Reader above).

So if you ask people which they prefer they will say multiple columns with short line lengths. Interestingly, if you ask them which they read faster, they will insist it is also the multiple columns with short line lengths, even though the data shows otherwise.

It’s a quandary: Do you give people what they prefer or go against their own preference and intuition, knowing that they will read faster if you use a longer line length and one column?

What would you do?
