Horse Shoe Buckle Large One of our largest Horseshoe Buckle fits a 1 1/2 inch wide leather belt. This buckle measures 2 inches wide x 1 15/16 inches tall. The nail holes on the shoe are squared, actually from a farrier nail, which makes this piece so authentic. A personal favorite and best seller. There is another large Horse shoe buckle that is more bulky, more for the men than maybe this one. Check out our Leather Page for a great selection of belts.
