I think that would be better to name the keyboard based on its size (not based on it's number of switches), for instance:
- class size 65% (it does not mean 65 keys, it means that the board uses our 65% size standard)
- class size 60%
- class size 70%
- etc
i agree in principal, but that would require everyone agreeing on the area defined as 100%. and would the keyboard on a Blackberry be considered a 10% keyboard just because the buttons are so small?
in practice, working with key count is logical and easier to agree on - 100% is between 101 (Winkeyless ANSI) and 105 (Winkeyful ISO) keys - so each key is ~ 1%
60% = 59-63 keys (standard keyboard without tenkey, nav cluster, and function row)
65% = 64-68 keys (usually 60% + one column)
70% = 69-73 keys (usually 60% + 3 partial columns (like OP))
75% = 74-78 keys (usually 60% + function row)
80% = 79-83 keys (usually 60% + function row + one column)
85% = 84-88 keys (usually 60% + function row + 3 partial columns (standard tenkeyless))
