Estimating Your Place in the Population
Let’s brainstorm examples of how to estimate what percentage of the population someone can read faster than based on their reading speed (in WPM). We’ll base this on research about average reading speeds and their distribution across populations, then tie those speeds to approximate percentiles. The goal is to keep this conceptual and grounded in research before turning it into code later. I’ll use widely accepted studies on reading speed to inform these examples and critically examine the data to ensure reasonable estimates.
Everyday Readers: The General Benchmark
Our first benchmark comes from a 2019 study by Marc Brysbaert. It looked at over 18,000 people and found the average adult reads nonfiction silently at 238 WPM. Most people fall between 175 and 300 WPM, with standout readers—like college students at 334 WPM or exceptional speed readers hitting 1000 WPM, as noted in research on visual reading limits (Dehaene, 2009)—showing the upper range. This variety highlights how reading speeds differ widely across a large population.
Speed Enthusiasts: The SwiftRead Study
Our second benchmark is from a 2023 SwiftRead study of their users, who are all about boosting reading speed. Their middle speed is 334 WPM, with 75% reading below 460 WPM. This group is faster than average because they’re actively training, giving us a different angle to compare your skills.
Putting It Together
So, how do we rank you? We take your WPM and see where it fits in these two distributions—one for typical readers and one for speed enthusiasts. This lets us estimate what percentage of each group you’re ahead of, without diving into tricky math. It’s a practical way to show your reading prowess!
