White space in design = comprehension, satisfaction
Ran across this post from artist friend Paul Soupiset’s blog that he wrote a while back. Good stuff!
Well designed pages with ample margins and leading = reading comprehension, satisfaction.
Margin white space affected both reading speed and comprehension; participants read the Margin text slower, but comprehended more than the No Margin text. In general, the results favored the use of Margins. The manipulation of Leading did not seem to impact reading performance, but did result in lower satisfaction with the layout and perceived eyestrain when paired with No Margins. Forty-seven percent of participants chose the Margins, Optimal Leading layout as their favorite, while 50% of the participants chose the No Margins, Sub-Optimal Leading text as their least favorite.
