A regulation baseball has a circumference of 9-91/4 inches (229-235 mm) and a diameter of 73-75 mm (255/64-215/16 in. or 73-75 mm). The weight of a regulation ball is not listed by official rules officials, but most weigh between 330 and 350 grams (12-13 oz).
The size of baseballs has varied over time. Early balls were made from cowhide, which was then wrapped with string to make them spherical. These balls were often black or dark blue in color. It was not until 1866 that Charles Hoyt & Co. produced the first white ball. This ball was made from the soft skin of cows killed for their meat rather than for their hides. These balls were more likely to be scuffed up after being hit since there was no hard leather inside like there is today. In 1903, an English company called W. G. Farish created the first ball made from leather. Called "Duroball", it was marketed as being better for play in the hot summer months when the leather ball would dry out earlier than the current ball does.
Modern baseballs are made from cowhide or synthetic materials such as polyurethane or polyvinyl chloride. They usually have a red border around they cover to help players identify their own ball during play.
A big league baseball now weighs between 5 and 51/4 ounces (142 and 149 g) and measures 9 to 91/4 inches (229-235 mm) in circumference (27/8-3 in or 73-76 mm in diameter). The ball must weigh between 1 and 11/2 pounds (0.5-0.6 kg) and be spherical in shape.
The weight of the ball and the size of the stitches used by the manufacturer determine how much pressure will be applied when hitting it. A heavy ball feels more "firm" when pitched than does a light one. Also, balls made from synthetic materials feel different from those made from leather because they don't have your natural oil on them. However, all modern balls are manufactured with the same goal in mind: to provide maximum distance while keeping the player's experience at its best possible for defense and batting.
In 1872, an Englishman named Alexander Cartwright established rules and regulations for baseball. These laws included a requirement that all balls must be made of rubber, which was first thought to be animal skin. In fact, cotton and linen yarn were used before this. But even though real leather has been used since then, only three manufacturers still make them today: Dunlop, Rawlings, and Wilson. Each makes balls of different sizes for men's, women's, and youth leagues as well as indoor games.
A baseball is a tiny, spherical, hard object. A baseball must weigh between 5 and 5 1/4 ounces (142 to 149 grams) and have a circumference of 9 to 9 1/4 inches (22.9 to 23.5 centimeters). The ball starts with a 1/2 ounce (14 g), 2.9 inch (7.4 cm) diameter cork core. This is then wrapped in leather until it forms a sphere. The final weight of a baseball varies depending on the material used for the leather wrapping. A standard ball weighs 5 ounces (141 grams). A light ball weighs 4 3/4 ounces (128 grams), a softball weights 5 1/4 ounces (149 grams), and a superball weights 6 ounces (170 grams).
Baseballs are made by hand, one at a time. First, the cork core is soaked in water to soften it enough to be worked like butter. Then the ball maker covers the core with wool fabric and begins to wrap it around the core using very thin layers of leather, about 20-24 inches (50-60 cm) long. As he or she wraps the leather around the core, the ball maker slips smaller and smaller pieces of wood into the holes in the core to keep it intact while still allowing the air to move inside the ball.
When finished, a single ball maker will have made several dozen balls before moving on to another project. They can make from two to five balls per hour. The leather ball makers use tools called "dies" to shape the balls as they go.
Teams in New York convened in the mid-1850s in an attempt to standardize baseball. Baseballs were regulated to weigh between 5 1/2 and 6 oz and have a circumference of 8 to 11 inches. Because baseballs were entirely handcrafted, there were several differences. Some manufacturers used leather balls while others used cork or rubber. Some had panels printed with pictures while others had painted scenes.
The first written record of baseball's rules comes from N. L. Bachman, who published them in 1857. They include a requirement that a ball be used in games played within New York City limits. The size of a baseball has been a subject of speculation since then. However, recent studies of early balls done by researchers at the National Baseball Hall of Fame and Museum provide evidence that the size of a baseball has not changed much over time.
In the 1840s, there are reports of balls being as large as 12 inches in circumference. In the late 1850s, balls made by Goodrich and Hurd with diameters of 10 inches or more are advertised. By the late 1860s, balls with 11-inch circumferences are being sold by vendors all across America.
In conclusion, baseballs in the 1850s were about 10 inches in circumference.
A baseball is a ball that is used in the sport of the same name. It has a circumference of 9 inches (22.9 cm) to 9 1/4 inches (23.5 cm). The ball is made of leather and usually white, but other colors are also available. Leather balls are manufactured by tanning and shaping cow hides into balls. Human hair can also be used instead.
The size of the ball determines which players are involved in the game. A softball is smaller than a baseball and weighs between 15 ounces and 20 ounces (425 grams and 500 grams). A baseball weighs between 16 ounces and 17 ounces (440 grams and 480 grams). A mass-produced ball tends to be around 16 ounces (440 grams), while a ball that is hand-stitched from natural materials may weigh more or less.
There are several methods used to measure the size of a baseball, including the bat dimension and the circle diameter. The bat dimension is measured at the end of the handle opposite where it meets the shaft. This is called the "sweet spot" on a baseball bat - it is here that a hitter wants the ball to hit. A large bat dimension allows for better hitting distance; while a small one limits the ability to drive the ball out of town.
The circle diameter is the distance across the ball's surface at its widest point.
