48 linear stones for a curved pool coping, plus 10% waste = 53.
Divide the wall perimeter (in inches) by the stone length plus joint width to get the number of linear stones. Add 2 cut pieces per corner for mitered joints, then add 10% for waste and breakage.
Coping stones typically come in 12, 18, or 24-inch lengths with 2-4 inch thickness. Width should overhang the wall by 1-2 inches on each side to create a drip edge that sheds water away from the wall face.
Use 3/8 to 1/2 inch joints for natural stone coping and 1/4 to 3/8 inch for cast stone or concrete coping. Wider joints accommodate natural stone irregularities better.
Concrete coping stones cost $4-$8 each, natural stone $8-$25 each, and cast stone $6-$15 each. A 60 ft wall typically needs 30-40 stones at $200-$800+ total depending on material.
