Baseball is a game of big numbers, but not every ballpark is built to pack in a huge crowd. While Dodger Stadium seats 56,000, the smallest park in the majors holds barely a fifth of that. Some of these intimate venues are temporary homes in transition, while others are beloved classics where the small size is the whole point. So which is the smallest MLB stadium right now, and what else makes the bottom of the list so interesting?
The capacities at the small end of the league range from around 13,000 up into the high 30,000s, and the reasons vary widely, from minor-league fill-ins to century-old ballparks that were never meant to be supersized.
The chart below ranks the smallest MLB stadiums from tiniest to largest, with each park’s capacity, team, and the year it opened. Take a look, then we’ll break down the stories behind the numbers.

The Smallest MLB Stadium
The smallest ballpark in Major League Baseball is Sutter Health Park in West Sacramento, which holds just 13,416 fans. It is the temporary home of the Athletics after the team left Oakland following the 2024 season, and it is actually a minor-league park, the regular home of the Triple-A Sacramento River Cats. The A’s are slated to stay there until their planned move to Las Vegas around 2028, so this unusually small big-league home is a short-term situation rather than a permanent one.
The Rest of the Bottom Five
Above Sutter Health Park, the next-smallest parks tell their own stories. Tropicana Field in St. Petersburg, the Rays’ home, sits at about 25,114 after the team returned for 2026, well clear of the next group. Then come a cluster of true big-league ballparks: Progressive Field in Cleveland at 34,830, LoanDepot Park in Miami at 36,742, and the iconic Fenway Park in Boston at 37,755. Fenway is the oldest park in the majors, opened in 1912, and its modest capacity is a feature of its cramped, historic charm rather than a flaw.
Why Some Parks Are So Small
There are a few different reasons a ballpark lands near the bottom. The Athletics and Rays are in temporary or transitional homes, which drags their capacities far below the league norm. Older parks like Fenway were simply built in a different era, when stadiums were smaller and squeezed into tight city blocks. And many modern parks were deliberately built smaller, since teams have learned that a more intimate, consistently fuller ballpark creates a better atmosphere and a stronger sense of demand than a cavernous stadium with empty seats. Several of the league’s newest parks, including LoanDepot Park and Truist Park, sit in the lower half of the capacity rankings by design.
Small Capacity, Big Character
A smaller park is not a lesser one. Fenway Park and Wrigley Field, two of the smallest and oldest venues in the league, are routinely ranked among the best places to watch a game anywhere in baseball. Capacity is only one measurement of a stadium, and it tells you nothing about the dimensions of the field itself, which vary dramatically from park to park and shape how the game is played. If you want to go deeper on how each ballpark is laid out, our guide to MLB stadium field dimensions and capacity breaks down the outfield distances, quirks, and 2026 changes for all 30 parks.
The Bottom Line
The smallest MLB stadium is Sutter Health Park at 13,416, a minor-league park serving as the Athletics’ temporary home, followed by Tropicana Field and then a group of full-size parks led by Progressive Field, LoanDepot Park, and Fenway. Some are small by circumstance and some by design, but the bottom of the capacity list is a reminder that in baseball, the size of the crowd is only a small part of what makes a ballpark special.
