During a 2002 clinic in Minnesota, Bob Marshall shared a method he says will work on most symmetrical hooves.
“You take a ruler and measure across the heels at the base of the frog,” he says, demonstrating with a preserved hoof model (Figure 1). “Then you let the ruler fall forward across the hoof and measure the distance between the quarters at that point (Figure 2).”
The International Horseshoeing Hall Of Famer from Mission, British Columbia, says forging a shoe to those heel and quarter dimensions usually results in a perfect fit.
See figures below.
Bob Marshall demonstrates his hoof measurement method. He first measures the heels at the base of the frog.
Marshall lets the ruler fall forward across the foot and measures the distance between the quarters at the position of the top of the ruler.

Marshall's tip was featured in the July/August issue of American Farriers Journal in a collection of shoe-fitting tips.
