The Blog Layout Decisions That Improve Reading Completion
Measure line length
60-80 characters per line. Wider breaks readability; narrower creates too-frequent eye returns.
Contrast and font size
18px minimum on body text. 1.7 line-height. Dark text on off-white background. Boring, but it works.
Progress indicators
Scroll progress bar, reading time estimate, and table of contents on long posts. Makes long content feel shorter.
