What follows are my personal typing tests results, expressed in percentage of my average touch-typing speed on a standard full-size keyboard and actual words per minute (wpm), using both virtual and hardware keyboards on various mobile devices.

The results reflect approximately two weeks of regular use of the keyboards and are based on unscientific tests by TypingMaster (Java test) and Learn2Type. Extended practice and use would yield improved speeds.

“UMPC mode” refers to holding a unit between two hands and typing with both thumbs, while “laptop mode” refers to setting the unit on a flat surface and typing with multiple fingers.

The results are provided for reference and context purposes only. Your own typing speeds will vary.

Note: I am now typing considerably faster on my Sony Vaio TZ notebook (90% keyboard size) than on a full-size keyboard. My average touch-typing speed on the latter is 86 wpm, while I now exceed 100+ wpm on the TZ. For the sake of the chart, I will continue to gauge my mobile keyboard typing speeds against my now obsolete touch-typing speed.
