A golf handicap is essentially a means of measuring a player’s potential ability. In so-called “stroke play,” it’s used to calculate the golfer’s net score in relation to the number of strokes actually played. Also known as medal play, this counts the total number of strokes taken at each hole in a round. To win a game of golf, you want to score the fewest number of strokes possible.

Golf handicaps are useful in allowing players of different proficiency levels to play against each other; they work to level the playing field. So, if you’re pitted against that guy who has ten more years of experience on the green than you do, it’s not a total waste of time.

The handicap difference between the two players determines the number of strokes that the high handicap player should get from the low handicap player during the round. Say your expert golfer pal’s handicap is 6 and yours is 21. You two are playing an 18-hole course where par is 70. Your friend would be expected to play all 18 holes in 76 strokes, while you would only be expected to play all 18 holes in 91 strokes.

While handicap systems are common among those who golf for fun, they are rarely—if ever—used in pro tournaments. These experts are largely expected to be able to make par without a handicap. This is also a raw way to assess professionals in parallel, without other influences.

If you’re not a professional golfer, however, you can still get a golf handicap to help you out. The United States Golf Association has useful information and a handicap calculator here. Most golf clubs with regional and national golf associations can administer an official handicap. This ensures your golf handicap is legitimate and recognized.
