All 30 MLB Stadiums: Capacity, Dimensions & What Makes Each Park Unique

No two Major League Baseball stadiums are alike. Unlike basketball arenas or football stadiums, which follow strict dimensional standards, MLB rules specify only minimum and maximum distances for certain measurements — leaving teams enormous creative freedom in how they design their parks. The result is 30 stadiums with completely different personalities, each one shaping the style of play and statistics produced within it in measurable ways.

This guide covers all 30 current MLB stadiums with key facts, dimensions, and what makes each park distinct — whether you're planning a visit, making a fantasy baseball decision, or just wanting to know your ballparks better.

American League East

Oriole Park at Camden Yards — Baltimore Orioles

Opened: 1992  ·  Capacity: ~44,970  ·  Surface: Grass  ·  Roof: Open

Camden Yards revolutionized stadium design when it opened in 1992 — it was the first "retro classic" park and inspired nearly every new stadium built in the decades that followed. The warehouse behind right field (the B&O Warehouse, which predates the stadium) is an iconic backdrop visible from much of the park. The dimensions are relatively symmetrical and the park plays as a mild hitter's park with the short right-field line at 318 feet.

Fenway Park — Boston Red Sox

Opened: 1912  ·  Capacity: ~37,755  ·  Surface: Grass  ·  Roof: Open

The oldest active MLB ballpark and one of the most storied venues in American sports. Fenway's defining feature is the Green Monster — the 37-foot-2-inch wall in left field just 310 feet from home plate. The Monster turns would-be home runs into doubles and creates a unique offensive environment. Fenway's irregular shape (a product of being built around existing Boston streets in 1912) gives it a character no other park can replicate.

Yankee Stadium — New York Yankees

Opened: 2009  ·  Capacity: ~46,537  ·  Surface: Grass  ·  Roof: Open

The current Yankee Stadium opened in 2009, directly across the street from the legendary original. It is one of the most expensive stadiums ever built and is known for its short right-field porch (314 feet down the line) which inflates left-handed home run totals significantly. The park consistently ranks among the most hitter-friendly in the American League, particularly for power hitters who pull the ball to right.

Tropicana Field — Tampa Bay Rays

Opened: 1990  ·  Capacity: ~25,025  ·  Surface: Artificial turf  ·  Roof: Fixed dome

The oldest dome currently in use in MLB, Tropicana Field is divisive among fans and players. The artificial turf and catwalk roof supports (which are technically in play if a ball hits them — the Rays have occasionally used this to their advantage) make it unlike any other park. The dome eliminates weather as a factor entirely, and the fast turf surface boosts infield singles and stolen base attempts. The Rays are expected to move into a new ballpark in St. Petersburg.

Rogers Centre — Toronto Blue Jays

Opened: 1989  ·  Capacity: ~49,282  ·  Surface: Artificial turf  ·  Roof: Retractable dome

The Rogers Centre (formerly SkyDome) was revolutionary when it opened in 1989 as the first stadium with a fully retractable roof. When it's open, Toronto's weather — often cold and windy in spring — comes into play. When closed, it becomes a dome environment with fast turf and suppressed offense. The dimensions are spacious, keeping home run totals relatively modest.

American League Central

Guaranteed Rate Field — Chicago White Sox

Opened: 1991  ·  Capacity: ~40,615  ·  Surface: Grass  ·  Roof: Open

A straightforward, symmetrical park with above-average dimensions that generally plays as a slight pitcher's park. The home run explosion at the 2021 Field of Dreams Game played in Iowa has zero relevance here. The park is scheduled to be replaced; the White Sox plan to move to a new stadium in the South Loop area of Chicago.

Progressive Field — Cleveland Guardians

Opened: 1994  ·  Capacity: ~34,788  ·  Surface: Grass  ·  Roof: Open

One of the better examples of the retro-classic era that followed Camden Yards, Progressive Field features an asymmetrical outfield with a deep left-center (410 feet) that suppresses left-handed power. Cold springs in Cleveland keep early-season offenses down. The park plays as a mild pitcher's park overall, particularly suppressing home runs relative to league average.

Comerica Park — Detroit Tigers

Opened: 2000  ·  Capacity: ~41,083  ·  Surface: Grass  ·  Roof: Open

Comerica Park opened in 2000 with cavernous outfield dimensions that made it one of the most extreme pitcher's parks in baseball. The original center field was 420 feet, left-center a challenging 395 feet. The fences have been brought in over the years, but the park still suppresses home runs significantly. Doubles and triples are more common here due to the deep alleys.

Kauffman Stadium — Kansas City Royals

Opened: 1973  ·  Capacity: ~37,903  ·  Surface: Grass  ·  Roof: Open

One of the best examples of 1970s stadium design, Kauffman features a famous fountain and waterfall beyond the outfield wall and wide, open sight lines. The park plays as relatively neutral to slightly pitcher-friendly. The Royals have long been known for their speed-and-defense style of play, which fits the spacious outfield well.

Target Field — Minnesota Twins

Opened: 2010  ·  Capacity: ~38,544  ·  Surface: Grass  ·  Roof: Open

Target Field is an open-air park in Minneapolis, which means cold temperatures can be a real factor in April and early May — sometimes even in September. When temperatures drop, offense drops with it. The park plays as a neutral to mild pitcher's park overall, but the early-season cold skews that number in the pitcher's favor. The left field line is relatively short at 339 feet.

American League West

Minute Maid Park — Houston Astros

Opened: 2000  ·  Capacity: ~41,168  ·  Surface: Grass  ·  Roof: Retractable

Minute Maid Park features a retractable roof that closes during Houston's brutal summer heat and frequent thunderstorms. The most distinctive feature is Tal's Hill — a grassy incline in center field with a flagpole, which was removed in 2016. Left field features one of the shortest foul lines in baseball (315 feet), which significantly boosts home run totals for right-handed hitters. The park consistently ranks as one of the most hitter-friendly in the AL.

Angel Stadium — Los Angeles Angels

Opened: 1966  ·  Capacity: ~45,517  ·  Surface: Grass  ·  Roof: Open

Angel Stadium is the second-oldest active ballpark in MLB after Fenway Park. The park is spacious with symmetrical dimensions and plays as a mild pitcher's park. The famous "Big A" scoreboard that originally stood in the outfield now serves as a sign outside the stadium. The relatively dry Southern California climate keeps conditions consistent throughout the season.

Oakland Coliseum — Oakland Athletics

Opened: 1966  ·  Capacity: ~46,765  ·  Surface: Grass  ·  Roof: Open

The Oakland Coliseum has long been considered one of the worst facilities in baseball — a multipurpose stadium designed primarily for football that was never ideal for baseball. The A's played their final games there in 2024 before moving to Sacramento temporarily ahead of a planned Las Vegas move. The deep outfield dimensions (400 feet to center) and cool Bay Area weather made it one of the premier pitcher's parks in baseball.

T-Mobile Park — Seattle Mariners

Opened: 1999  ·  Capacity: ~47,929  ·  Surface: Grass  ·  Roof: Retractable

T-Mobile Park is consistently rated one of the best fan experiences in baseball, with excellent sight lines and a retractable roof that keeps Seattle's rain out without eliminating the outdoor atmosphere (the sides stay open even when the roof is closed). The deep power alleys (375 feet) suppress home runs and make it one of the better pitcher's parks in the AL.

Globe Life Field — Texas Rangers

Opened: 2020  ·  Capacity: ~40,300  ·  Surface: Artificial turf  ·  Roof: Retractable

Globe Life Field opened during the 2020 pandemic season (hosting the entire World Series in a bubble). The retractable roof keeps out Texas's oppressive summer heat. The artificial turf surface is unusual for a new stadium in 2020, when most parks had transitioned to natural grass. The park has played as a moderate hitter's park in its early years.

National League East

Truist Park — Atlanta Braves

Opened: 2017  ·  Capacity: ~41,084  ·  Surface: Grass  ·  Roof: Open

The Braves' suburban Cobb County park opened in 2017 with excellent fan amenities and a lively surrounding entertainment district called The Battery. The park plays as a fairly neutral to slight hitter's park, with dimensions that are spacious but not extreme. Atlanta's warm summer temperatures support good offensive production throughout the season.

loanDepot park — Miami Marlins

Opened: 2012  ·  Capacity: ~36,742  ·  Surface: Artificial turf  ·  Roof: Retractable

The Marlins' park features a retractable roof that protects against Miami's frequent summer afternoon thunderstorms. The park is known for its colorful art installations beyond the outfield walls and its fast artificial turf surface. Despite the smaller dimensions, the park has generally played as fairly pitcher-neutral, partly due to the dome-like atmosphere when the roof is closed.

Citi Field — New York Mets

Opened: 2009  ·  Capacity: ~41,922  ·  Surface: Grass  ·  Roof: Open

Citi Field replaced Shea Stadium and is modeled aesthetically after Ebbets Field. The park originally opened with extremely deep dimensions that suppressed offense severely; the fences were brought in significantly in 2012 to help hitters. Today it plays as a mild pitcher's park with particular suppression of left-handed power due to the deep left-center gap.

Citizens Bank Park — Philadelphia Phillies

Opened: 2004  ·  Capacity: ~42,901  ·  Surface: Grass  ·  Roof: Open

Citizens Bank Park consistently ranks as one of the top hitter's parks in baseball. The short dimensions (330 feet to left, 329 feet to right), combined with Philadelphia's warm summers and the park's open design that allows wind currents, inflate both home run totals and run scoring significantly. Pitchers who are used to neutral parks often get shellacked in their first start at Citizens Bank.

Nationals Park — Washington Nationals

Opened: 2008  ·  Capacity: ~41,339  ·  Surface: Grass  ·  Roof: Open

Nationals Park sits along the Anacostia waterfront and features an above-average home run environment due to its relatively modest dimensions (336 feet to left, 335 to right). The park is known for its Presidents Race between innings, a mascot race that has become one of the most entertaining in-game promotions in all of baseball.

National League Central

Wrigley Field — Chicago Cubs

Opened: 1914  ·  Capacity: ~41,649  ·  Surface: Grass  ·  Roof: Open

The second-oldest active ballpark in MLB (after Fenway) and one of the most beloved venues in American sports. Wrigley is famous for its ivy-covered outfield walls, the hand-operated scoreboard, and the rooftop seating across Sheffield and Waveland Avenues. Wind is everything at Wrigley — blowing in off Lake Michigan suppresses offense dramatically; blowing out can turn routine fly balls into home runs. Check the wind direction before any Wrigley bet or fantasy start.

Great American Ball Park — Cincinnati Reds

Opened: 2003  ·  Capacity: ~42,319  ·  Surface: Grass  ·  Roof: Open

Great American Ball Park sits on the Ohio River and is one of the most hitter-friendly parks in baseball — reliably ranking near the top in home run park factors each season. The short porch in left (328 feet) and right (325 feet) combined with warm Cincinnati summers create an environment that punishes fly ball pitchers and rewards power hitters.

American Family Field — Milwaukee Brewers

Opened: 2001  ·  Capacity: ~41,900  ·  Surface: Artificial turf  ·  Roof: Retractable

The Brewers' retractable roof handles Wisconsin's unpredictable spring and fall weather effectively. The artificial turf surface favors speed and soft contact. The park plays as moderate on the offensive spectrum — not extreme in either direction. Famous for Bernie Brewer's slide after Brewers home runs.

PNC Park — Pittsburgh Pirates

Opened: 2001  ·  Capacity: ~38,362  ·  Surface: Grass  ·  Roof: Open

Widely considered one of the most beautiful ballparks in baseball, PNC Park sits on the north shore of the Allegheny River with the Pittsburgh skyline and Roberto Clemente Bridge as a backdrop beyond right field. The park plays as a mild pitcher's park, with the deep power alleys (389 feet to left-center, 399 feet to center) providing room for outfielders to run down fly balls.

Busch Stadium — St. Louis Cardinals

Opened: 2006  ·  Capacity: ~44,494  ·  Surface: Grass  ·  Roof: Open

The current Busch Stadium opened in 2006 with the Gateway Arch visible beyond center field — one of the most recognizable backdrops in baseball. The park plays as a mild pitcher's park with fairly neutral dimensions. The Cardinals consistently draw some of the best attendance in the NL, and the park's design reflects the franchise's blue-collar, baseball-first fan culture.

National League West

Chase Field — Arizona Diamondbacks

Opened: 1998  ·  Capacity: ~48,519  ·  Surface: Artificial turf  ·  Roof: Retractable

Chase Field's retractable roof is a necessity in Phoenix, where summer temperatures regularly exceed 110°F — making outdoor baseball impossible from June through September. The artificial turf plays fast, and the park features a swimming pool in right-center field that can be rented for groups. Despite the thin desert air (Phoenix sits at 1,086 feet elevation), the park has not been an extreme home run environment.

Coors Field — Colorado Rockies

Opened: 1995  ·  Capacity: ~46,897  ·  Surface: Grass  ·  Roof: Open

Coors Field is the most extreme offensive environment in Major League Baseball. At 5,280 feet above sea level — exactly one mile high — the thin air allows batted balls to travel approximately 9% farther than at sea level. ERAs for pitchers at Coors routinely inflate by 1.00–1.50 runs. The Rockies store baseballs in a humidor to control moisture, which has slightly reduced the park's impact, but Coors remains by far the best hitter's park in baseball. Any stat analysis for Colorado players must account for the Coors effect heavily.

Dodger Stadium — Los Angeles Dodgers

Opened: 1962  ·  Capacity: ~56,000  ·  Surface: Grass  ·  Roof: Open

The third-oldest active ballpark in MLB, Dodger Stadium is one of the best-maintained venues in baseball despite its age. It has the largest seating capacity in the majors and sits in the hills of Chavez Ravine with mountain views beyond the outfield. The park plays as a mild pitcher's park — the cool evenings brought by coastal marine layer and the spacious dimensions (395 feet to center) suppress offense modestly relative to the NL average.

Petco Park — San Diego Padres

Opened: 2004  ·  Capacity: ~40,209  ·  Surface: Grass  ·  Roof: Open

Petco Park ranks among the most pitcher-friendly parks in baseball, consistently suppressing home runs and run scoring year after year. The park's deep dimensions (396 to left-center, 396 to right-center), cool marine-layer evenings from the nearby Pacific Ocean, and large foul territory all benefit pitchers. Left-handed hitters especially struggle here due to the deep power alley in left-center.

Oracle Park — San Francisco Giants

Opened: 2000  ·  Capacity: ~41,915  ·  Surface: Grass  ·  Roof: Open

Oracle Park sits on San Francisco Bay with the right-field wall opening directly to McCovey Cove — home balls hit into the water are called "splash hits," a tradition started by Barry Bonds. The cold, foggy Bay Area evenings dramatically suppress offense: in contrast to the "Coors effect," the thick marine air in San Francisco is actually denser than standard air at sea level, creating a slight headwind for batted balls heading toward right field. The park is consistently one of the best pitcher's parks in the NL.

How Park Factors Affect Statistics

Understanding the differences between parks is essential for interpreting statistics correctly. A pitcher with a 3.20 ERA at Petco Park has likely pitched better than a pitcher with a 3.20 ERA at Coors Field. A hitter with 30 home runs at Citizens Bank Park may be a lesser performer than a hitter with 25 home runs at Oracle Park.

This is precisely why park-adjusted statistics like OPS+, ERA+, wRC+, and ERA- exist — they normalize for the park environment to allow fair comparisons.
