An earth-boring bit has a bit body having a plurality of bit legs extending longitudinally therefrom, each bit leg comprising one or more groove regions formed along a laterally outer surface thereof. Each groove region comprises a fluid course for drilling fluid and cuttings to pass across the outer surface. A ridge may be disposed adjacent a lower edge of one or more of the groove regions. Each groove region may also be positioned at differing heights on the bit legs. Methods of forming earth-boring bits are also disclosed.
