What is the official height (in inches) the greens should be in golf - amatuar and on the tour?

Answer 1

Depends on what type of grass and time of year. A lot of the PGA events cut the greens so low and don't water them during the event they have to rebuild them following the event.

Most of the green's are 3/16

healthy, vigorous green can be maintained at a very short cutting height (as low as 1/8-inch) for short periods of time without serious consequences if it's been prepared properly and weather conditions are acceptable. Courses hosting tournaments often take months (and spend significant extra money) to bring greens up to an ultrafast speed for PGA Tour players. For example, the greens at Augusta National or Oakmont may "stimp" up to 14 when properly prepared and dry.

Answer 2

There is no official height. It is determined by speed. stimp meter. a typical public course will usually mow them at a higher height because it is less stress on the plant and if they have a lot of rounds being played it is difficult and expensive to have the greens rolling fast all the time. I played a course 2 weeks ago and the greens were being mowed at 0.85 of an inch. were i work we are mowing at 0.125. on 1 course 0.150 on another (although they are mown at 2 different heights they still stimp the same) and 0.200 on the public course. As doug said grass species will also effect the height you can mow at. some grasses love to be mown low were others don't handle it too well. Also mowing height is not the only factor involved in getting greens fast. regular topdressing verticutting rolling and lack of water will make greens fly
