Cutting elements having laterally elongated shapes for use with earth-boring tools, earth-boring tools including such cutting elements, and related methods

A method of forming a fixed cutter earth-boring rotary drill bit, comprising:

• selecting at least one PDC cutting element including a substrate and a volume of polycrystalline diamond material on an end of the substrate, an exposed surface of the volume of polycrystalline diamond material defining a front cutting face of the PDC cutting element, the at least one PDC cutting element having an elongated shape in a lateral dimension parallel to a front cutting face of the at least one PDC cutting element, the at least one PDC cutting element having a maximum lateral width in a first direction parallel to the front cutting face of the at least one PDC cutting element, a maximum lateral length in a second direction parallel to the front cutting face of the at least one PDC cutting element, the second direction perpendicular to the first direction, the maximum lateral length being at least two times the maximum lateral width, wherein the at least one PDC cutting element is configured such that an area of a wear scar on the at least one PDC cutting element will be maintained below 22.6 mm2 at a linear wear distance of 3.81 mm or less measured from an unworn cutting edge of the at least one PDC cutting element in the second direction;
• and
• mounting the at least one PDC cutting element to a body of the fixed-cutter earth-boring rotary drill bit.
