A farrier's measurement instrument is disclosed to use in locating the preferred position for affixing a shoe to the bottom of a horse's hoof. The invention is comprised of a base of a rectilinear shape with a lower surface, a flange disposed orthogonally to the base at one end of the base, such that a long edge of the flange is aligned with the lower surface of the base, a slot disposed centrally and longitudinally within the base, wherein the slot extends to the edge of the base opposite the flange, a sliding rule which can slide longitudinally within the slot and has a lower surface coplanar with the lower surface of the base forming a planar lower surface of the farrier's measurement instrument, and a first and a second measurement scales disposed on the lower surface of the farrier's measurement instrument. The increment of the graduations of the second measurement scale is either directly or inversely three times proportional to those of the first measurement scale. The first measurement scale may be graduated in SAE or metric units.
