Free Typing Speed Test — What Is a Good WPM?

The average typing speed for adults is 40 words per minute (WPM). Professional typists average 65–75 WPM. Competitive typists reach 100–150 WPM. For reference, the average person speaks at 125–150 WPM — most people speak faster than they type. A typing speed above 60 WPM is generally considered fast enough for professional work without typing being a bottleneck. Our typing speed test measures your WPM and accuracy across a standardised passage, giving you a comparable score you can track over time.

Reaction Time Test — What Is a Good Reaction Time?

Average human reaction time to a visual stimulus is 200–250 milliseconds. Athletes typically average 150–200 ms. Reaction time worsens measurably with sleep deprivation (each hour of missed sleep adds approximately 10 ms), alcohol (even at legal driving limits), and ageing (reaction time slows roughly 10–15% per decade from age 30). Our reaction time test measures your average across multiple attempts to reduce the effect of individual variation.

Memory Test Online — How Good Is Your Short-Term Memory?

Short-term (working) memory capacity averages 7 items (plus or minus 2) — a finding established by psychologist George Miller in 1956 and still broadly accurate. This capacity declines with age and is impaired by sleep deprivation, stress, and distraction. Our memory test measures your digit span — the number of items you can hold and recall in sequence. It is a quick, validated measure of working memory capacity used in neuropsychological assessment.

Frequently Asked Questions

The average adult types at 40 WPM. A good speed is 60–80 WPM. Professional typists and programmers typically reach 80–120 WPM. Take our Typing Speed Test to measure yours and get a personalised improvement tip.

Average reaction time to a visual stimulus is 200–250 milliseconds. Under 200ms is excellent (top ~10%). Reaction time worsens with age, fatigue, alcohol, and distractions. Measure yours at our Reaction Time Test.

Our Colour Blind Test uses Ishihara-style plates — circular patterns of coloured dots hiding numbers or shapes. People with red-green colour deficiency cannot see the hidden number. The test can detect the most common types of colour vision deficiency.

Studies show that regularly practicing memory tasks improves performance in those specific tasks. Working memory training can also have modest transfer effects on attention and executive function. The best approach is variety — combine memory games with physical exercise and adequate sleep.

The most effective method is to focus on accuracy first, speed second — typing slowly and correctly builds correct muscle memory faster. Touch typing is approximately 35% faster than hunt-and-peck typing on average. Practice in 15–20 minute focused sessions. Most people can increase from 40 WPM to 70 WPM within 4–6 weeks of daily practice.

Yes — reaction time slows progressively from around age 24, declining approximately 10–15% per decade. By age 70, average reaction time is roughly 50–60% slower than peak. However, experience and anticipation can partially compensate. Regular physical exercise, good sleep, and cognitive stimulation slow the age-related decline.

The scientific evidence is mixed. A large 2014 Stanford study concluded that commercial brain training programs had not been shown to produce meaningful improvements in real-world cognitive ability. However, specific skills like working memory capacity and processing speed show modest improvements with targeted practice. The strongest evidence for long-term brain health points to physical exercise, quality sleep, and learning new complex skills.
