A club's weight distribution relative to a fixed fulcrum point, typically 14 inches from the butt (grip end) of the club. Swingweight is measured in alpha-numeric units such as D-1, D-2. The letters used are A through G, with numerals from 0-9 (up to 10 for G).
The higher a club’s letter-number unit, the closer its balance point is to the head, and the heavier it will feel when swung. The lightest possible swingweight is A-0; the heaviest is G-10. For men, the standard swingweights are D-0 and D-1; for women, C-5 to C-7.
Swingweight is not the same as a club’s total weight, measured in grams.
