How Many Stitches Are On a Baseball? Here’s How One is Made

The game of baseball evolved a great deal since its early beginnings. Alexander Cartwright (no, it was not Abner Doubleday) first established a true set of rules for America’s Pastime in 1845, including doing away with the practice of pegging runners.

Since then, baseball changed quite a bit. Babe Ruth transformed the game forever (and also struck out against this kick-ass girl), Reggie Jackson and Derek Jeter became World Series heroes, and players like Nolan Ryan and Barry Bonds elevated baseball to new levels.

The baseball itself also looks different today than it did back in the 1800s. Everything from the stitching to the leather and the size and weight of MLB’s official baseball is completely different than its early origins.

Of course, one of the more common topics is the number of stitches on the baseball. It’s a handy tidbit of knowledge if you ever find yourself engulfed in a round of baseball trivia. Let’s “unwind” just what all goes into the making of a baseball.

History of the Baseball

Early versions of the baseball weren’t exactly high-tech. A rubber core was formed from old, melted shoes that was then wrapped in yarn and leather.

In the 1840s and 1850s, pitchers typically made their own balls and pitched with them. Balls back then were called “lemon peel balls” for their distinct four lines and stitching design that gave it the appearance of a lemon. They were also smaller and weighed less than the ones we’re used to, which meant home runs and high-scoring baseball games were common.


It wasn’t until 1876 that the sport had one standardized ball. According to Smithsonian Magazine, Boston Red Sox pitcher A.G. Spalding (ever heard of that name?) retired from the game and convinced the National League of Professional Baseball Clubs to use the balls he made. Spalding’s company then produced the official baseball for the next 100 years.

In 1976, MLB switched from Spalding’s to Rawlings Sporting Goods. All these balls are produced in Costa Rica, where Rawlings is based out of, and then shipped to the United States.

How The Modern Ball is Made

According to MLB’s rulebook, MLB baseballs must weigh between 5 and 5.25 ounces and measure between 9 and 9.25 inches in circumference.

Official major league baseballs first start with a core of cork mixed with rubber. That is covered in a layer of black rubber before another red rubber layer is added. Yarn winding comes next. A revolving machine winds more than 200 yards of wool and another 150 yards of fine white cotton around the core.

Once rubber cement is applied, two strips of white horsehide or cowhide leather in the shape of a figure-8 are applied, stapled and stitched together. In 1934, the American League and National League first agreed on the cushion cork center, yarn wrappings, rubber cement coating and the horsehide cover. Cowhide covering was adopted in 1974.

The baseball stitching process is the most intricate and time consuming part of the creation of a baseball.

Once the cowhide covers have been stapled on, someone has to hand-stitch them with red thread. In total, 108 hand-stitched double stitches are used to cover the baseball. At the MLB level, these red stitches and the rest of what is used in a baseball are stored in temperature controlled facilities and wound under tension so no “soft spots” exist in the ball, according to Smithsonian Magazine.

How Long Does Hand Stitching Take?

These 108 red threads are carefully applied to each baseball by hand.

A total of 88 inches of waxed red thread are used in the process. According to, this process takes an average of 13-14 minutes for each ball.

Typically, the first and last stitch are completely hidden. Once the threading is finished, the staples are taken out and the ball is put through a rolling machine for another 15 seconds to eliminate any raised stitches. Once the ball passes inspection, it’s good to go.
