So how do we find a width for the content that accommodates both focused/engaged reading (shorter line lengths, less density) and scanning/searching/skimming (longer line lengths, more density)? Based on the above information it seems safe to assume we should limit the width by some amount, while still enabling readers to skim and search around, obtaining a visual map of the page without having to scroll too much.
