Average typing speed is 40-50 WPM for non-typists; professional typists average 65-75 WPM; power users reach 100+ WPM. The difference matters: at 40 WPM, a 2,000-word document takes 50 minutes to type. At 80 WPM, it takes 25 minutes. Typing faster with the same accuracy essentially doubles your writing productivity for everything from code to emails to reports.
The fastest way to improve is consistent daily practice (15-20 minutes), focusing on accuracy before speed. Errors are more costly than slowness: at 95% accuracy you are spending almost as much time correcting mistakes as gaining from typing fast. The WPM line chart tracks your improvement over the last 50 tests, making your progress visible over days and weeks of practice.
