FAQ
What is the average reading speed?
Adults: 200-300 words per minute (wpm) for casual reading. College students: 250-350 wpm. Speed readers: 600-1000 wpm. Technical/academic material: 100-200 wpm (slower comprehension). Fiction reads 10-20% faster than non-fiction. Screen reading is 20-30% slower than print for many people.
How can I increase my reading speed?
Eliminate subvocalization (saying words in head - limits to ~250 wpm). Use pointer (finger/pen) to guide eyes. Practice with apps: Spreeder, ReadMe!, Velocity. Read in chunks (3-5 words) not word-by-word. Improve vocabulary (less pausing on unfamiliar words). Speed reading courses claim 600-1000 wpm with training.
What is a good article length for web content?
Optimal: 1500-2500 words (7-10 min read time). Most readers won't finish 10+ minute articles. Blog posts: 500-1500 words (3-7 min). Long-form: 2500-5000 words for in-depth topics (requires highly engaged audience). Medium.com popularized reading time estimates for better UX.
