- What is a good spacebar speed?
- Around 6 presses per second is fast for a full-size keyboard, and the best runs cluster between 8 and 10. Beyond that people are usually using a technique such as alternating thumbs rather than pressing normally.
- Why is my count lower than my clicking speed?
- A spacebar has a longer travel and a heavier spring than a mouse switch, and one thumb is doing all the work. Comparing the two measures the keyboard, not you.
- Does this wear out the key?
- Mechanical switches are rated for tens of millions of presses and a membrane for a few million, so a minute of testing does not register. Your thumb will complain long before the switch does.
- Why do held keys not count?
- Because the repeats come from the operating system's key repeat rate, not from you. Counting them would turn the test into a settings check and would let anyone win by leaning on the bar.
