Point 18: People read faster with a longer line length, but
they prefer a short line length.
100 characters per line is the optimal length for on-screen reading speed.
We actually prefer shorter line lengths between 45-72 characters per line.
We read one single wide column faster than multiple column pages.
But we prefer multiple column layouts
People READ longer line lengths and single column text FASTER.
People LIKE shorter line lengths and multiple columns, but read SLOWER.
A study was conducted through CXL Institute to compare
form completion times for a single-column form versus a
multi-column form. The results shared that the
single-column form was completed faster at an average
15.4 seconds than the multi-column form.
