3:1 binding wires (if read aloud would be three to one) means that the wires will thread through 3 holes per inch of a document (typically 24 loops for A5 & 34 for A4). The looped wire will therefore be spaced more closely together than the 2:1 pitch giving the wires a much tighter look. It is worth noting that 3:1 binding wires can accept fewer sheets of paper than 2:1 wires.
