1. A lead for spinal cord simulation, the lead comprising:
a paddle having a distal end and a proximal end along a midline of the paddle; and
an electrode array distributed in the paddle, the electrode array comprising a first column of electrodes and a second column of electrodes;
wherein:
the first column of electrodes and the second column of electrodes are symmetric about the midline of the paddle;
the first column of electrodes and the second column of electrodes each comprises a plurality of electrodes; and
a vertical inter-electrode distance between the plurality of electrodes within the first or second column of electrodes decreases from the distal end to the proximal end.
