The percentage of golfers who can break 90 varies depending on the source. According to the United States Golf Association, 73.4% of golfers have a handicap of 17.9 or better, which means that 73.4% of golfers can regularly break 90. However, this percentage is highly debated and considered dubious by many golfers. The National Golf Foundation gives a more realistic and accurate percentage, stating that only 21% of golfers get an average score of 80 to 89, which would mean that only 26% of golfers regularly break 90. Other sources suggest that the number of golfers who can break 90 is around 70% or 7 out of 10 golfers. It is important to note that breaking 90 consistently is difficult, especially for newer golfers who do not have a solid game yet.
