A putter selection aid includes a mat having a ball placement indicia, a stroke line extending through the ball placement indicia, and three demarcated areas. The first demarcated area is spaced from the stroke line by a first mean distance (d1), the second demarcated area is spaced from the stroke line by a second mean distance (d2), and the third demarcated area is spaced from the stroke line by a third mean distance (d3), where d1<d2<d3. The first demarcated area includes a first reference to a first putter style, the second demarcated area includes a second reference to a second putter style, and the third demarcated area includes a third reference to a third putter style. |
