65% - This is a 60% with arrows and extra navigation keys on the main layer. Just like a 60%, the remaining keys are accessed via layers.

75% - The main layer includes the alpha numeric cluster, navigation keys, and f row. This form factor is basically a TKL(tenkeyless) in a condensed form factor.

80%/TKL/Tenkeyless - Like the 75%, a TKL includes the alpha numeric cluster, navigation keys, and f row but in a more standard layout. This form factor is a full size without a numpad.
