Golf balls have a diameter of 1.68 inches (42.67 mm) and a circumference of 5.28 inches (134.05 mm). They weigh 1.62 oz (45.93 g). The specifications of the golf ball are controlled by The Royal & Ancient Gulf Club of St. Andrews and the United States Golf Association (USGA). The USGA Rules of Golf state that a conforming golf ball cannot be smaller than 1.680 inches in diameter and must weigh no more than 1.620 ounces. The weight and diameter of golf balls are optimized to provide the most ball velocity and distance possible, along with a controllable spin rate.

What You'll Learn
Golf ball weight: 1.62 oz (45.93 g) max
Golf is a game that requires a lot of precision and accuracy. The equipment used in the game, including the golf ball, is highly regulated to ensure fairness. The weight of a golf ball is a critical factor that can significantly impact the shot and give golfers an unfair advantage.
The maximum weight of a golf ball is 1.62 ounces or 45.93 grams. This regulation is set by the USGA (United States Golf Association) and the R&A, the two primary governing organizations for golf equipment. Any golf ball exceeding this weight is considered non-conforming and is prohibited from use in competitions. While there may be slight variations in the weight of golf balls from different manufacturers, they must not exceed the maximum limit.
It is important to note that while there is a maximum weight limit, there is no legal minimum weight for golf balls. Golfers are free to use balls that weigh less than 1.62 ounces, but they cannot go over the specified maximum. This flexibility allows golfers to choose balls that suit their playing style and preferences.
The weight of a golf ball can impact its performance. Heavier golf balls tend to fly farther due to increased momentum. However, if a heavier ball is also larger in diameter, the increased drag may cause it to fly shorter distances. Additionally, heavier balls can produce more inconsistent results. Therefore, golfers need to carefully consider the weight of the golf ball they choose to use, as it can influence their performance on the course.
Golf ball weight can vary depending on the condition of the ball. New golf balls tend to have very little difference in weight, with negligible variations between individual balls. However, as balls age and experience wear and tear, their weight can decrease. Poor condition balls may have a weight difference of several grams compared to new or well-maintained balls. This variation in weight due to condition is something golfers should consider when choosing their balls, as it can impact their performance.

Golf ball diameter: 1.68 (42.67 mm) min
Golf balls have a diameter of 1.68 inches (or 42.67 mm) and a circumference of 5.28 inches (or 134.05 mm). The weight of a golf ball is 1.62 ounces (45.93 grams). The specifications for golf balls are controlled by The Royal & Ancient Golf Club of St. Andrews and the United States Golf Association (USGA).
The USGA Rules of Golf state that a "conforming" golf ball must have a diameter of no less than 1.68 inches (42.67 mm). The weight of the ball must not be greater than 1.62 ounces (45.93 grams). The ball must also be spherically symmetrical, meaning that it must be spherical and have a symmetrical arrangement of dimples on its surface.
The diameter of modern golf balls is designed to work well with the size of the golf hole, which has a diameter of 4.25 inches. The weight and diameter of golf balls are optimised to provide the most ball velocity and distance possible, along with a controllable spin rate.
Prior to 1990, the USGA and R&A had different regulations for the minimum diameter of a golf ball. The USGA mandated a 1.68-inch diameter limit, while the R&A allowed a smaller diameter of 1.62 inches. In 1952, there were two standardised sizes for golf balls: the smaller British ball was required to have a diameter of at least 1.62 inches, while the larger American ball had a minimum diameter of 1.68 inches.

Golf ball dimples: 300-500, symmetrically arranged
A golf ball is 1.68 inches (42.67 mm) in diameter, with a circumference of 5.28 inches (134.05 mm). Its mass is 1.62 oz (45.93 g).
Golf balls have between 300 and 500 dimples, with the average number being 336. These dimples are not just there for aesthetic purposes; they are there to change the airflow around the ball and create lift. The dimple pattern on a golf ball affects a host of factors, such as air resistance, distance and trajectory. The dimples on a golf ball are called indentations, and they are created by imprinting a design onto the surface of the ball using a mold. The mold is then filled with a rubber or plastic compound and left to cure. Once cured, the ball is painted and given its final touches.
The dimples on a golf ball must be symmetrically arranged, with each dimple having the same depth. This is in contrast to asymmetrical dimples, which are not evenly spaced and have varying depths. The symmetrical dimple pattern creates very small turbulence behind the ball, called the boundary layer. This boundary layer separates from the ball's surface, forming vortices (rotating air currents) that cause drag on the ball.
The number of dimples on a golf ball is not as important as the design and pattern of these dimples. The best dimple pattern seems to be one deeper dimple followed by a shallow dimple.

Golf ball colour: traditionally white, now also other colours
Golf balls have a diameter of 1.68 inches (42.67 mm) and a circumference of 5.28 inches (134.05 mm). Their mass is 1.62 oz (45.93 g). The specifications of the golf ball are controlled by The Royal & Ancient Gulf Club of St. Andrews and the United States Golf Association.
Golf balls are traditionally white, but they are now available in other colours too. The first golf balls, which date back to the 17th century, were made of leather, filled with feathers, and painted white. This was likely because white paint was readily available at the time, and provided a bright colour that contrasted with the natural brown of the feathers. The colour white was also probably preferred because these balls were expensive to produce, and their owners would not want to lose them.
Today, there is a wide range of high-visibility colours and finishes available for golf balls. Players can purchase balls in almost any colour or pattern. However, golf balls used in upper-tier professional golf have been slow to change and have stuck with the traditional white colour.
While some sources suggest that white golf balls are harder to spot during games, others argue that it is more important to find them on the ground than in the air. The cry of "fore!" is intended to warn people when a ball is coming towards them, rather than for them to visually spot it.

Golf ball history: from feather-stuffed to rubber to polymer
The evolution of the golf ball has been a long and winding journey, with several materials and designs coming in and out of fashion over the centuries. The game of golf itself is believed to have originated in Scotland, with golf balls made of beech wood being handcrafted by carpenters as early as the 14th century and continuing through to the 17th century.
The next significant development came in the form of the "feathery" or "featherie" ball, which was a piece of leather stuffed with goose feathers, sewn tight, dried hard, and painted. These balls dominated the game of golf for over 200 years, from the early 1400s to the late 1840s, and were handcrafted by skilled artisans. However, they were expensive to make, prone to water damage, and had a limited lifespan, with players getting only a few rounds out of each ball.
In the mid-19th century, the "guttie" ball, made from the dried sap of the Sapodilla tree, revolutionized the game. This ball, also known as "gutty", was created by Rev. Dr. Robert Adams in 1848 and offered a more affordable and durable option. It had a rubber-like feel and was formed into a ball shape by heating and shaping the sap. The guttie ball brought golf to the masses and was used until the late 19th century.
The late 19th century saw the introduction of the "Haskell" ball, named after Coburn Haskell, who developed it in 1898. This ball consisted of a solid rubber core with rubber threads wrapped tightly around it and a cover made of gutta-percha sap. The Haskell ball brought significant improvements in control, feel, and distance, and soon became the new standard.
In the 1960s, golf ball design underwent another revolution. Rubber was replaced by new, cheaper synthetic materials, and wound and liquid cores were replaced by solid ones. This ushered in the modern era of golf ball design, with computerized and robotic testing leading to advancements in aerodynamics and customization to suit a player's strengths and weaknesses.
