How do you measure Cor on a golf course?
Oct 24, 2005 · Updated on 05/24/19. "COR" is an acronym for "Coefficient of Restitution." It's a term from the world of science and physics, but one that many golfers know because it is also used in conjunction with golf clubs. "Coefficient of restitution" is a term describing the energy transference between two objects.

What should my smash factor be?
A golfer would hope to achieve a smash factor near 1.50 on driver shots. That means for a 100 mph club speed the ball speed would be 150 mph. The higher the loft of the club, the lower the smash factor is expected to be. A PW should have a smash factor near 1.25.

What is COR in golf clubs?
COR stands for Coefficient of Restitution. This is defined as the ratio of the final velocity to the initial velocity between two objects after their collision.
How is COR calculated?
The club speed after impact is subtracted from the ball speed after impact. This is then divided by the club speed before impact.
How is COR measured?
To measure COR you need to launch a ball at the clubface. The speed velocity of the ball before and after it has made contact with the clubface is then measured. This is a complicated test to run so the R&A introduced a measurement called Characteristic Time (CT) to measure the elasticity of the clubface.
How does COR effect driving distance?
Whenever you hit a shot there is always some energy lost when the club hits the ball. At impact the ball is compressed against the clubface and can squash up to 30% of its diameter against the driver face. This is where the energy is lost.
Technical Specs
Tom Wishon, golf club designer and founder of Tom Wishon Golf Technology, gives a more technical definition of COR this way:
Regulation of Coefficient of Restitution in Golf Clubs
The USGA and R&A regulate COR in golf clubs to prevent manufacturers from making golf clubs that totally overwhelm golf courses with distance. The current COR limit in golf clubs is 0.830. Any club with a COR measuring higher than .830 is ruled non-conforming .
Distance Differences In Clubs of Different CORs
What kind of differences in distance performance will two golf clubs of differing CORs exhibit? We turn once again to Wishon for the answer:
What is COR?
COR is an acronym that stands for “Coefficient of Restitution, and is a term that originates from the world of physics, but has now been applied to the world of golf.
What is CT?
In 2004, the USGA and the R&A decided to move away from COR values to regulate drivers and instead have decided to use a term called characteristic time (CT).

What is the CT test?
The CT test also measures the spring-like effect of a club face, except it uses a small, portable pendulum system that strikes the face with a steel ball. Sensors then read the amount of time the two objects stay in contact with each other. The limit of time placed on golf clubs is ...
Did Xander Schauffele fail the CT test?
As you may remember in 2019 ahead of The Open Championship, Xander Schauffele had a run-in with the R&A after his driver failed a CT test. During the aftermath of that ordeal, the PGA Tour implemented mandatory driver testing for the 2019-2020 season.

What Is CT?
- In 2004, the USGA and the R&A decided to move away from COR values to regulate drivers and instead have decided to use a term called characteristic time (CT). COR value is still the metric used to regulate all other clubs, however.
