Major League Baseball (MLB) was founded in 1903 and is the oldest existing professional sports league in both the United States and Canada. Although baseball's heyday as America's favorite pastime is long gone, having been eclipsed by football, MLB remains one of the most popular sports league in the United States. In 2018, MLB games enjoyed an average attendance of 28,660 people, and the total number of spectators reached almost 70 million, which is more than any other professional sports league in the world.

In this post, we'll take a look at every MLB stadium ranked by their seating capacity. But we also include other facts like when a stadium opened, the type of playing surface, and the combined cost it took to build and renovate each stadium (in 2018 prices). Unlike NFL stadiums and NBA arenas, MLB ballparks are more varied in their layout and design, so we also include details like ballpark typology and the distance to center field.

Before you scroll down to find out the rankings, here are some interesting facts about MLB stadiums:

• The largest stadium is Dodger Stadium with a capacity of 56,000 and the smallest stadium is Tropicana Stadium with a capacity of 31,042, which means MLB's largest stadium is 80% larger than the smallest one in terms of capacity.
• The oldest MLB stadium still in use is Boston's Fenway Park, which opened in 1912.
• There are currently 30 teams in the MLB (29 in the USA and one in Canada) and every team has their own stadium.
• The average stadium seating capacity is 42,675.
• Arizona Diamondback's Chase Field has a swimming pool located in right-center field just 415 feet from home plate, which means it's possible for batters to hit a home run into the pool.
• The most expensive MLB stadium is Yankee Stadium, which cost a whopping $2.7 billion to build.
