The BSBL Infinite Keystroke Database

Tables showing the average percentage user accuracy for each keystroke on a QWERTY, AZERTY and QWERTZ keyboard in alphabetical order.

(all languages combined except Greek and Russian)

Click here to go to Page 5 to view the same data in Order of Average Accuracy

The data on this page is collected from the following Better Skills Better Life products combined:-

  • All Typing Tests
  • All Competitions
  • Classic Typing Tutor
  • Classic Typing Tutor with Dictate
  • Dual Learning

…in all of the following languages combined:-

American English, Catalan, Danish, Dutch, English, Finnish, French, German, Italian, Brazilian Portuguese, Spanish, Swedish

The tables show the results of our analysis of every keypress made by all of our users in every one of the above languages. The main take-away from the data on this page is that we can see the average accuracy for every computer keyboard key based on a worldwide typist basis.

The data is set out in the tables 1-6 below to show the overall Average Accuracy Percentage Per Key. The Percentage Accuracy per key is calculated as follows:

(Correct Keypresses made by user ÷ Total keypresses made by user) x 100

e.g. To calculate the user accuracy for pressing the character ‘a’ :

(where the user makes 75 Correct keypresses of character ‘a’ ÷ 100 Total keypresses intended to be a keypress for character ‘a’) x 100 = 75%

To see the language specific analyses of the above plus statistics for Greek and Russian characters too, go to Page 9. Note that you need to be a Registered User or Subscriber to view all of the data so click here to Register first.
